The TanStack Start guide separates migration, Prisma Client generation, and seeding steps. The supported driver list adds prisma-sqlite-bun-adapter. TypeORM headings correct “Loosing” to “Losing.”
Deployment workflow instructions
apps/docs/content/docs/orm/*/prisma-client/deployment/deploy-database-changes-with-prisma-migrate.mdx, apps/docs/content/docs/orm/*/prisma-client/deployment/traditional/deploy-to-render.mdx
Deployment examples use npm ci. Render documentation links directly to the infrastructure-as-code setup guide.
Cloudflare compatibility configuration
apps/docs/content/docs/orm/*/prisma-client/deployment/edge/deploy-to-cloudflare.mdx
Cloudflare instructions replace node_compat in wrangler.toml with nodejs_compat in wrangler.jsonc and add compatibility date 2026-08-23. The previous Pages workaround note is removed.

Cloudflare Workers nodejs_compat automatically enabled compatibility date August 4 2026 documentation

💡 Result:

<search_synthesis>
As of August 4, 2026, Cloudflare Workers automatically enables Node.js compatibility for any Worker with a compatibility date of 2026-08-04 or later [1][2]. Key technical details regarding this change: Automatic Enabling: The nodejs_compat and nodejs_compat_v2 compatibility flags are now enabled by default for these compatibility dates [1][3]. You do not need to manually include these flags in your Wrangler configuration file for new projects [1][2]. Redundancy: Because these flags are enabled by default, explicitly including nodejs_compat or nodejs_compat_v2 in your configuration for a compatibility date of 2026-08-04 or later is redundant [1][4]. In some local development environments, including these flags may cause errors because the runtime now considers them redundant [5][4]. Existing projects are not required to remove these flags when updating their compatibility date [1][2]. Opting Out: To completely disable Node.js compatibility for a Worker with a compatibility date of 2026-08-04 or later, you must explicitly add both no_nodejs_compat and no_nodejs_compat_v2 to your configuration&#39;s compatibility_flags [1][6]. Adding only one of these flags is insufficient because the runtime evaluates them independently [6]. Example configuration to disable Node.js compatibility: { "compatibility_date": "2026-09-16", "compatibility_flags": [ "no_nodejs_compat", "no_nodejs_compat_v2" ] } Compatibility for Older Dates: Workers configured with a compatibility date earlier than 2026-08-04 are unaffected by this change and continue to require the manual addition of the nodejs_compat flag to enable Node.js APIs [1][2].

<title>Node.js compatibility is now enabled by default · Changelog</title> https://developers.cloudflare.com/changelog/post/2026-08-04-nodejs-compat-default/ Node.js compatibility is now enabled by default · Changelog # Changelog New updates and improvements at Cloudflare. August 4, 2026 ## Node.js compatibility is now enabled by default Workers now enable the `nodejs_compat` and `nodejs_compat_v2` compatibility flags by default for compatibility dates of `2026-08-04` or later. These flags are not used for these compatibility dates because the compatibility date enables the same behavior. This means all Node.js built-in APIs supported by the Workers runtime are available by default, including `node:crypto`, `node:buffer`, `node:stream`, `node:net`, `node:dns`, `node:fs`, `node:http`, and more. npm packages that depend on these APIs will work without additional configuration. Workers using an earlier compatibility date are not affected. They can still opt in by adding `nodejs_compat` to `compatibility_flags`. New projects do not need to add either flag. Existing projects can update their compatibility date without removing them. Wrangler, Miniflare, the Cloudflare Vite plugin, and Vitest Pool Workers ignore these redundant flags when starting the runtime. To turn off Node.js compatibility completely, remove any `nodejs_compat` and `nodejs_compat_v2` flags. Then add both of the following flags: ``` { "$schema": "./node_modules/wrangler/config-schema.json", // Set this to today&`#39`;s date "compatibility_date": "2026-09-10", "compatibility_flags": [ "no_nodejs_compat", "no_nodejs_compat_v2" ] } ``` Copy code to clipboard ``` # Set this to today&`#39`;s date compatibility_date = "2026-09-10" compatibility_flags = ["no_nodejs_compat", "no_nodejs_compat_v2"] ``` Copy code to clipboard For more information, refer to the Node.js compatibility documentation. <title>Node.js compatibility · Cloudflare Workers docs</title> https://developers.cloudflare.com/workers/runtime-apis/nodejs/ For compatibility dates of `2026-08-04` or later, Workers enables both `nodejs_compat` and `nodejs_compat_v2` by default. Built-in Node.js APIs and polyfills are available without additional configuration. ... For these compatibility dates, `nodejs_compat` and `nodejs_compat_v2` are not used because the compatibility date enables the same behavior. Existing projects do not need to remove these flags when updating their compatibility date. Omit them from new configurations. ... For compatibility dates from `2024-09-23` through `2026-08-03`, add the `nodejs_compat` compatibility flag to your Wrangler configuration file to opt in: ... ``` { "compatibility_date": "2026-08-03", "compatibility_flags": ["nodejs_compat"] } ... To turn off Node.js compatibility completely with a compatibility date of `2026-08-04` or later, remove the positive flags if present. Then add both `no_nodejs_compat` and `no_nodejs_compat_v2`. For configuration examples, refer to the Node.js compatibility flag. ... The following stubs are enabled automatically only when the `nodejs_compat` compatibility flag is enabled and your Worker&`#39`;s compatibility date is on or after the date shown. To enable one earlier, add the corresponding enable flag. To keep one unavailable after that date, add the corresponding disable flag. ... | Stub module | Enabled with `nodejs_compat` on or after | Enable flag | Disable flag | | --- | --- | --- | --- | | `node:http2` ↗ | `2025-09-01` | `enable_nodejs_http2_module` | `disable_nodejs_http2_module` | | `node:vm` ↗ | `2025-10-01` | `enable_nodejs_vm_module` | `disable_nodejs_vm_module` | ... | `node:cluster` ↗ | `2025-12-04` | `enable_nodejs_cluster_module` | `disable_nodejs_cluster_module` | | `node:domain` ↗ | `2025-12-04` | `enable_nodejs_domain_module` | `disable_nodejs_domain_module` | ... | `node:trace_events` ↗ | `2025-12-04` | `enable_nodejs_trace_events_module` | `disable_nodejs_trace_events_module` | ... | `node:wasi` ↗ | `2025-12-04` | `enable_nodejs_wasi_module` | `disable_nodejs_wasi_module` | ... :_stream_wrap ... | `2026-01-29` | `enable_nodejs ... stream_wrap_module` | `disable_nodejs_stream_wrap_module` | ... `2026-0 ... `enable_nodejs_dgram_module` | `disable_nodejs_dgram ... module` | ... | `node ... `2026-0 ... `enable_nodejs_inspector_module` | `disable_nodejs_inspector_module` | ... | `node ... sqlite` ↗ | `2026-0 ... ` | `enable_nodejs_sqlite_module` | `disable_nodejs_sqlite_module` | ... `20 ... 6-0 ... 7` | `enable_nodejs_child_process_ ... ` | `disable_nodejs_child ... `20 ... nodejs_readline_module ... | `node: ... `2026- ... 3-17` ... nodejs_repl ... module` | ... | `node:tty` ... | `2026-03-17` | `enable_nodejs_tty_module` | `disable_nodejs_tty_module` | ... | `node:v8 ... `20 ...

These flags are not used for these compatibility dates. Existing projects do not need to remove them when updating their compatibility date. For earlier dates, add `nodejs_compat` to your Wrangler configuration file to opt in. For instructions to turn off Node.js compatibility, refer to the Node.js compatibility flag. The `process` ↗ module in Node.js provides a number of useful APIs related to the current process. Initially Workers only supported `nextTick`, `env`, `exit`, `getBuiltinModule`, `platform` and `features` on process, which was then updated with the `enable_nodejs_process_v2` flag to include most Node.js process features. Refer to the Node.js documentation for `process` ↗ for more information. Workers-specific implementation details apply when adapting Node.js process support for a serverless environment, which are described in more detail below. ## `process.env` In the Node.js implementation of `process.env`, the `env` object is a copy of the environment variables at the time the process was started. In the Workers implementation, there is no process-level environment, so by default `env` is an empty object. You can still set and get values from `env`, and those will be globally persistent for all Workers running in the same isolate and context (for example, the same Workers entry point). If you use Wrangler or the Cloudflare Vite plugin, `process.env.NODE_ENV` is statically replaced at build time and is not a runtime value. Refer to Bundling for more information. When Node.js compatibility is enabled and the `nodejs_compat_populate_process_env` compatibility flag is set (enabled by default for compatibility dates on or after 2025-04-01), `process.env` will contain any environment variables, secrets, or version metadata metadata that has been configured on your Worker. Setting any value on `process.env` will coerce that value into a string. ### Alternative: Import `env` from `cloudflare:workers` Instead of using `process.env`, you can import `env` from `cloudflare:workers` to access environment variables and all other bindings from anywhere in your code. ``` import * as process from "node:process"; export default { fetch(req, env) { // Set process.env.FOO to the value of env.FOO if process.env.FOO is not already set // and env.FOO is a string. process.env.FOO ??= (() => { if (typeof env.FOO === "string") { return env.FOO; } })(); }, }; ``` Copy code to clipboard It is strongly recommended that you do not replace the entire `process.env` object with the cloudflare `env` object. Doing so will cause you to lose any environment variables that were set previously and will cause unexpected behavior for other Workers running in the same isolate. Specifically, it would cause inconsistency with the `process.env` object when accessed via named imports. ``` import * as process from "node:process"; import { env } from "node:process"; process.env === env; // true! they are the same object process.env = {}; // replace the object! Do not do this! process.env === env; // false! they are no longer the same object // From this point forward, any changes to process.env will not be reflected in env, // and vice versa! ``` Copy code to clipboard ## `process.nextTick()` The Workers implementation of `process.nextTick()` is a wrapper for the standard Web Platform API `queueMicrotask()` ↗. ``` import { env, nextTick } from "node:process"; env["FOO"] = "bar"; console.log(env["FOO"]); // Prints: bar nextTick(() => { console.log("next tick"); }); ``` Copy code to clipboard ## Stdio `process.stdout` ↗, `process.stderr` ↗ and `process.stdin` ↗ are supported as streams. `stdin` is treated as an …[truncated] <title>wrangler@4.122.0</title> https://github.com/cloudflare/workers-sdk/releases/tag/wrangler%404.122.0 # wrangler@4.122.0 - Tag: wrangler@4.122.0 - Repository: cloudflare/workers-sdk - Published: 2026-08-12T14:20:44Z - Author: workers-devprod --- ### Minor Changes - [`#15123`](https://github.com/cloudflare/workers-sdk/pull/15123) [`d0c976c`](https://github.com/cloudflare/workers-sdk/commit/d0c976c04ad890fcef56305ded11f1405e89273e) Thanks [`@dependabot`](https://github.com/apps/dependabot)! - Detect Node.js compatibility from the compatibility date, now that `nodejs_compat` is enabled by default As of compatibility date `2026-08-04`, workerd enables the `nodejs_compat` and `nodejs_compat_v2` compatibility flags by default. Previously these tools only treated Node.js compatibility as enabled when one of those flags was listed explicitly, so a Worker on a compatibility date of `2026-08-04` or later without the flag would get Node.js APIs from the runtime but no Node.js polyfills from the bundler, and `process.env` could be substituted with an empty object at build time. They now resolve these flags the same way workerd does, and honour `no_nodejs_compat` to opt out. To keep Node.js compatibility switched off on a newer compatibility date, specify both `no_nodejs_compat` and `no_nodejs_compat_v2`, since each flag has its own default. `@cloudflare/vitest-pool-workers` needs `nodejs_compat_v2` for its own test runner, so it continues to override a project that opts out of it. On a compatibility date that enables the flag anyway, it now drops the opt-out rather than adding the flag back, which workerd would reject — previously this stopped such a project from running any tests at all. `wrangler types` also no longer attributes its `@types/node` suggestion to "the `nodejs_compat` flag", which it can now make for Workers that do not set the flag at all. ### Patch Changes - [`#15123`](https://github.com/cloudflare/workers-sdk/pull/15123) [`d0c976c`](https://github.com/cloudflare/workers-sdk/commit/d0c976c04ad890fcef56305ded11f1405e89273e) Thanks [`@dependabot`](https://github.com/apps/dependabot)! - Update dependencies of "miniflare", "wrangler" The following dependency versions have been updated: | Dependency | From | To | | ------------------------- | ------------- | ------------- | | `@cloudflare/workers-types` | ^5.20260804.1 | ^5.20260811.1 | | workerd | 1.20260804.1 | 1.20260811.1 | - [`#15148`](https://github.com/cloudflare/workers-sdk/pull/15148) [`0b82b15`](https://github.com/cloudflare/workers-sdk/commit/0b82b1574b3327681a0091716ed274c8f0544a48) Thanks [`@jamesopstad`](https://github.com/jamesopstad)! - Ignore a `nodejs_compat` compatibility flag that the compatibility date already enables workerd rejects a compatibility flag that its compatibility date enables by default, so a Worker configured with both a compatibility date of `2026-08-04` or later **and** `nodejs_compat` failed to start locally with "The compatibility flag nodejs_compat became the default as of 2026-08-04 so does not need to be specified anymore".

Remove the redundant nodejs_compat flag.

For compatibility_date 2026-08-23, Workers enables Node.js compatibility by default. Cloudflare recommends omitting the flag from new configurations. The existing-project exception does not apply to this new configuration example.

Cloudflare Workers nodejs_compat automatically enabled compatibility date August 4 2026 documentation

💡 Result:

<search_synthesis>
Yes, as of August 4, 2026, Cloudflare Workers automatically enables Node.js compatibility by default for any Worker with a compatibility date of 2026-08-04 or later [1][2]. When your compatibility date is set to 2026-08-04 or later, both the nodejs_compat and nodejs_compat_v2 compatibility flags are enabled automatically [1][3]. Consequently, you do not need to manually add these flags to your configuration [1][2]. In fact, if you explicitly include nodejs_compat in your configuration for these later dates, tools like Wrangler and the local runtime (workerd) may treat it as redundant [1][4][5]. Key points regarding this change: - Automatic Enablement: Built-in Node.js APIs (such as node:crypto, node:buffer, node:stream, etc.) are available by default without additional configuration [1][2]. - Existing Projects: You do not need to remove the nodejs_compat or nodejs_compat_v2 flags from existing projects when you update your compatibility date to 2026-08-04 or later; they will simply be ignored [1][2][3]. - Opting Out: If you need to disable Node.js compatibility entirely, you must explicitly add both no_nodejs_compat and no_nodejs_compat_v2 to your compatibility_flags configuration [1][2][5]. For projects using a compatibility date earlier than 2026-08-04, you must still explicitly opt in by adding the nodejs_compat flag to your configuration file [2][3].

<title>Node.js compatibility is now enabled by default · Changelog</title> https://developers.cloudflare.com/changelog/post/2026-08-04-nodejs-compat-default/ Node.js compatibility is now enabled by default · Changelog # Changelog New updates and improvements at Cloudflare. August 4, 2026 ## Node.js compatibility is now enabled by default Workers now enable the `nodejs_compat` and `nodejs_compat_v2` compatibility flags by default for compatibility dates of `2026-08-04` or later. These flags are not used for these compatibility dates because the compatibility date enables the same behavior. This means all Node.js built-in APIs supported by the Workers runtime are available by default, including `node:crypto`, `node:buffer`, `node:stream`, `node:net`, `node:dns`, `node:fs`, `node:http`, and more. npm packages that depend on these APIs will work without additional configuration. Workers using an earlier compatibility date are not affected. They can still opt in by adding `nodejs_compat` to `compatibility_flags`. New projects do not need to add either flag. Existing projects can update their compatibility date without removing them. Wrangler, Miniflare, the Cloudflare Vite plugin, and Vitest Pool Workers ignore these redundant flags when starting the runtime. To turn off Node.js compatibility completely, remove any `nodejs_compat` and `nodejs_compat_v2` flags. Then add both of the following flags: ``` { "$schema": "./node_modules/wrangler/config-schema.json", // Set this to today&`#39`;s date "compatibility_date": "2026-09-10", "compatibility_flags": [ "no_nodejs_compat", "no_nodejs_compat_v2" ] } ``` Copy code to clipboard ``` # Set this to today&`#39`;s date compatibility_date = "2026-09-10" compatibility_flags = ["no_nodejs_compat", "no_nodejs_compat_v2"] ``` Copy code to clipboard For more information, refer to the Node.js compatibility documentation. <title>Node.js compatibility · Cloudflare Workers docs</title> https://developers.cloudflare.com/workers/runtime-apis/nodejs/ For compatibility dates of `2026-08-04` or later, Workers enables both `nodejs_compat` and `nodejs_compat_v2` by default.

These flags are not used for these compatibility dates. Existing projects do not need to remove them when updating their compatibility date. For earlier dates, add `nodejs_compat` to your Wrangler configuration file to opt in. For instructions to turn off Node.js compatibility, refer to the Node.js compatibility flag. The `process` ↗ module in Node.js provides a number of useful APIs related to the current process. Initially Workers only supported `nextTick`, `env`, `exit`, `getBuiltinModule`, `platform` and `features` on process, which was then updated with the `enable_nodejs_process_v2` flag to include most Node.js process features. Refer to the Node.js documentation for `process` ↗ for more information. Workers-specific implementation details apply when adapting Node.js process support for a serverless environment, which are described in more detail below. ## `process.env` In the Node.js implementation of `process.env`, the `env` object is a copy of the environment variables at the time the process was started. In the Workers implementation, there is no process-level environment, so by default `env` is an empty object. You can still set and get values from `env`, and those will be globally persistent for all Workers running in the same isolate and context (for example, the same Workers entry point). If you use Wrangler or the Cloudflare Vite plugin, `process.env.NODE_ENV` is statically replaced at build time and is not a runtime value. Refer to Bundling for more information. When Node.js compatibility is enabled and the `nodejs_compat_populate_process_env` compatibility flag is set (enabled by default for compatibility dates on or after 2025-04-01), `process.env` will contain any environment variables, secrets, or version metadata metadata that has been configured on your Worker. Setting any value on `process.env` will coerce that value into a string. ### Alternative: Import `env` from `cloudflare:workers` Instead of using `process.env`, you can import `env` from `cloudflare:workers` to access environment variables and all other bindings from anywhere in your code. ``` import * as process from "node:process"; export default { fetch(req, env) { // Set process.env.FOO to the value of env.FOO if process.env.FOO is not already set // and env.FOO is a string. process.env.FOO ??= (() => { if (typeof env.FOO === "string") { return env.FOO; } })(); }, }; ``` Copy code to clipboard It is strongly recommended that you do not replace the entire `process.env` object with the cloudflare `env` object. Doing so will cause you to lose any environment variables that were set previously and will cause unexpected behavior for other Workers running in the same isolate. Specifically, it would cause inconsistency with the `process.env` object when accessed via named imports. ``` import * as process from "node:process"; import { env } from "node:process"; process.env === env; // true! they are the same object process.env = {}; // replace the object! Do not do this! process.env === env; // false! they are no longer the same object // From this point forward, any changes to process.env will not be reflected in env, // and vice versa! ``` Copy code to clipboard ## `process.nextTick()` The Workers implementation of `process.nextTick()` is a wrapper for the standard Web Platform API `queueMicrotask()` ↗. ``` import { env, nextTick } from "node:process"; env["FOO"] = "bar"; console.log(env["FOO"]); // Prints: bar nextTick(() => { console.log("next tick"); }); ``` Copy code to clipboard ## Stdio `process.stdout` ↗, `process.stderr` ↗ and `process.stdin` ↗ are supported as streams. `stdin` is treated as an …[truncated] <title>Strip redundant nodejs_compat flags</title> GitHub pull request 15148 in cloudflare/workers-sdk (link omitted to avoid creating a cross-reference) # Strip redundant nodejs_compat flags - State: merged - Author: jamesopstad - Created: 2026-08-12T12:30:59Z - Updated: 2026-08-12T13:15:07Z - Repository: cloudflare/workers-sdk - Number: `#15148` - +157 -24 in 7 files - Merged: 2026-08-12T13:15:05Z - Merge commit: 0b82b1574b3327681a0091716ed274c8f0544a48 - Reviewers: NuroDev --- Ignore a `nodejs_compat` compatibility flag that the compatibility date already enables Fixes https://github.com/cloudflare/workers-sdk/issues/15146 workerd rejects a compatibility flag that its compatibility date enables by default, so a Worker configured with both a compatibility date of `2026-08-04` or later **and** `nodejs_compat` failed to start locally with "The compatibility flag nodejs_compat became the default as of 2026-08-04 so does not need to be specified anymore".

Previously these tools only treated Node.js compatibility as enabled when one of those flags was listed explicitly, so a Worker on a compatibility date of `2026-08-04` or later without the flag would get Node.js APIs from the runtime but no Node.js polyfills from the bundler, and `process.env` could be substituted with an empty object at build time. They now resolve these flags the same way workerd does, and honour `no_nodejs_compat` to opt out. To keep Node.js compatibility switched off on a newer compatibility date, specify both `no_nodejs_compat` and `no_nodejs_compat_v2`, since each flag has its own default. `@cloudflare/vitest-pool-workers` needs `nodejs_compat_v2` for its own test runner, so it continues to override a project that opts out of it. On a compatibility date that enables the flag anyway, it now drops the opt-out rather than adding the flag back, which workerd would reject — previously this stopped such a project from running any tests at all. `wrangler types` also no longer attributes its `@types/node` suggestion to "the `nodejs_compat` flag", which it can now make for Workers that do not set the flag at all. ### Patch Changes - [`#15123`](https://github.com/cloudflare/workers-sdk/pull/15123) [`d0c976c`](https://github.com/cloudflare/workers-sdk/commit/d0c976c04ad890fcef56305ded11f1405e89273e) Thanks [`@dependabot`](https://github.com/apps/dependabot)! - Update dependencies of "miniflare", "wrangler" The following dependency versions have been updated: | Dependency | From | To | | ------------------------- | ------------- | ------------- | | `@cloudflare/workers-types` | ^5.20260804.1 | ^5.20260811.1 | | workerd | 1.20260804.1 | 1.20260811.1 | - [`#15148`](https://github.com/cloudflare/workers-sdk/pull/15148) [`0b82b15`](https://github.com/cloudflare/workers-sdk/commit/0b82b1574b3327681a0091716ed274c8f0544a48) Thanks [`@jamesopstad`](https://github.com/jamesopstad)! - Ignore a `nodejs_compat` compatibility flag that the compatibility date already enables workerd rejects a compatibility flag that its compatibility date enables by default, so a Worker configured with both a compatibility date of `2026-08-04` or later **and** `nodejs_compat` failed to start locally with "The compatibility flag nodejs_compat became the default as of 2026-08-04 so does not need to be specified anymore".

To deploy Prisma ORM to Cloudflare Workers, the nodejs_compat compatibility flag is required if you are using a database driver that relies on TCP (such as the traditional pg driver) [1][2]. For projects with a compatibility date of 2026-08-04 or later, Node.js compatibility is enabled by default in the Cloudflare Workers runtime, meaning the nodejs_compat flag is no longer strictly necessary for enabling Node.js APIs [3]. However, it is common practice to continue including it or to check specific requirements in your configuration [3][4]. For compatibility dates between 2024-09-23 and 2026-08-03, you must manually add the nodejs_compat flag to your wrangler.jsonc or wrangler.toml configuration file to enable the necessary Node.js runtime APIs [5][3]: { "compatibility_flags": ["nodejs_compat"], "compatibility_date": "2026-09-16" } If you are using Prisma Postgres or other serverless HTTP-based drivers, the compatibility flag is not required, as these drivers communicate over HTTP instead of TCP [1][2]. Always ensure your compatibility_date is set to a recent date to leverage the latest runtime features and fixes [5].

The nodejs_compat flag is a compatibility flag used in Cloudflare Workers to enable a subset of Node.js APIs directly as Runtime APIs, allowing developers to use these APIs without bundling external polyfills [1][2]. Regarding your query for 2026-08-04, this date does not correspond to a specific release or change event for the nodejs_compat flag. Instead, the compatibility date is a general configuration setting in Cloudflare Workers [1][2]. To use the latest Node.js compatibility features, it is recommended to set your compatibility date to the current date (e.g., 2026-08-11 or later) in your wrangler configuration [1]. Key points about nodejs_compat: - It enables built-in Node.js runtime APIs [1][3]. - If your compatibility date is 2024-09-23 or later, the nodejs_compat flag automatically enables nodejs_compat_v2, which provides additional polyfills and globals, though it may increase bundle size [1][2]. - You can control the inclusion of v2 or specific behaviors (like populating process.env) by adding secondary flags such as no_nodejs_compat_v2 or nodejs_compat_populate_process_env alongside nodejs_compat [1][3][4]. - Unlike other compatibility flags, Cloudflare does not expect nodejs_compat to become active by default at a future date; it must be explicitly enabled in your configuration [1][2].

Cloudflare 2026-08-04 nodejs_compat default compatibility-flags documentation conflict official

💡 Result:

<search_synthesis>
As of August 4, 2026, Cloudflare enabled Node.js compatibility by default for Workers with a compatibility date of 2026-08-04 or later [1][2]. This change automatically enables both the nodejs_compat and nodejs_compat_v2 compatibility flags [1][2]. Regarding the documentation and configuration "conflict" or redundancy: 1. Redundancy: Because these flags are now enabled by default for compatibility dates of 2026-08-04 or later, explicitly including nodejs_compat or nodejs_compat_v2 in your Wrangler configuration is no longer necessary [1][2]. 2. Runtime Behavior: The Workers runtime (workerd) will treat these flags as redundant [3][4]. Including them when your compatibility date is 2026-08-04 or later may cause your Worker to fail to start locally, as the runtime rejects these flags because they are already active by default [3][4]. 3. Official Guidance: Cloudflare&#39;s updated documentation and tooling (Wrangler) now automatically ignore or drop these redundant flags when they are specified in configurations for workers using modern compatibility dates [1][3][4]. New projects should omit these flags entirely [1]. 4. How to Disable: If you need to disable Node.js compatibility while using a compatibility date of 2026-08-04 or later, you must explicitly add both no_nodejs_compat and no_nodejs_compat_v2 to your compatibility_flags [1][2][4]. Existing projects do not need to remove the flags when updating their compatibility date [1][2], as the tooling now handles the redundancy automatically [3][4]. You should continue to set your compatibility_date to a recent date to ensure access to the latest features and runtime improvements [5].

<title>Node.js compatibility is now enabled by default · Changelog</title> https://developers.cloudflare.com/changelog/post/2026-08-04-nodejs-compat-default/ Node.js compatibility is now enabled by default · Changelog # Changelog New updates and improvements at Cloudflare. August 4, 2026 ## Node.js compatibility is now enabled by default Workers now enable the `nodejs_compat` and `nodejs_compat_v2` compatibility flags by default for compatibility dates of `2026-08-04` or later. These flags are not used for these compatibility dates because the compatibility date enables the same behavior. This means all Node.js built-in APIs supported by the Workers runtime are available by default, including `node:crypto`, `node:buffer`, `node:stream`, `node:net`, `node:dns`, `node:fs`, `node:http`, and more. npm packages that depend on these APIs will work without additional configuration. Workers using an earlier compatibility date are not affected. They can still opt in by adding `nodejs_compat` to `compatibility_flags`. New projects do not need to add either flag. Existing projects can update their compatibility date without removing them. Wrangler, Miniflare, the Cloudflare Vite plugin, and Vitest Pool Workers ignore these redundant flags when starting the runtime. To turn off Node.js compatibility completely, remove any `nodejs_compat` and `nodejs_compat_v2` flags. Then add both of the following flags: ``` { "$schema": "./node_modules/wrangler/config-schema.json", // Set this to today&`#39`;s date "compatibility_date": "2026-09-10", "compatibility_flags": [ "no_nodejs_compat", "no_nodejs_compat_v2" ] } ``` Copy code to clipboard ``` # Set this to today&`#39`;s date compatibility_date = "2026-09-10" compatibility_flags = ["no_nodejs_compat", "no_nodejs_compat_v2"] ``` Copy code to clipboard For more information, refer to the Node.js compatibility documentation. <title>Node.js compatibility · Cloudflare Workers docs</title> https://developers.cloudflare.com/workers/runtime-apis/nodejs/ For compatibility dates of `2026-08-04` or later, Workers enables both `nodejs_compat` and `nodejs_compat_v2` by default. Built-in Node.js APIs and polyfills are available without additional configuration. ... For these compatibility dates, `nodejs_compat` and `nodejs_compat_v2` are not used because the compatibility date enables the same behavior. Existing projects do not need to remove these flags when updating their compatibility date. Omit them from new configurations. ... For compatibility dates from `2024-09-23` through `2026-08-03`, add the `nodejs_compat` compatibility flag to your Wrangler configuration file to opt in: ... ``` { "compatibility_date": "2026-08-03", "compatibility_flags": ["nodejs_compat"] } ... ``` compatibility_date = "2026-08-03" compatibility_flags = [ "nodejs_compat" ] ... To turn off Node.js compatibility completely with a compatibility date of `2026-08-04` or later, remove the positive flags if present. Then add both `no_nodejs_compat` and `no_nodejs_compat_v2`. For configuration examples, refer to the Node.js compatibility flag. ... The following stubs are enabled automatically only when the `nodejs_compat` compatibility flag is enabled and your Worker&`#39`;s compatibility date is on or after the date shown. To enable one earlier, add the corresponding enable flag. To keep one unavailable after that date, add the corresponding disable flag. <title>Strip redundant nodejs_compat flags</title> GitHub pull request 15148 in cloudflare/workers-sdk (link omitted to avoid creating a cross-reference) # Strip redundant nodejs_compat flags - State: merged - Author: jamesopstad - Created: 2026-08-12T12:30:59Z - Updated: 2026-08-12T13:15:07Z - Repository: cloudflare/workers-sdk - Number: `#15148` - +157 -24 in 7 files - Merged: 2026-08-12T13:15:05Z - Merge commit: 0b82b1574b3327681a0091716ed274c8f0544a48 - Reviewers: NuroDev --- Ignore a `nodejs_compat` compatibility flag that the compatibility date already enables Fixes https://github.com/cloudflare/workers-sdk/issues/15146 workerd rejects a compatibility flag that its compatibility date enables by default, so a Worker configured with both a compatibility date of `2026-08-04` or later **and** `nodejs_compat` failed to start locally with "The compatibility flag nodejs_compat became the default as of 2026-08-04 so does not need to be specified anymore".

Previously these tools only treated Node.js compatibility as enabled when one of those flags was listed explicitly, so a Worker on a compatibility date of `2026-08-04` or later without the flag would get Node.js APIs from the runtime but no Node.js polyfills from the bundler, and `process.env` could be substituted with an empty object at build time. They now resolve these flags the same way workerd does, and honour `no_nodejs_compat` to opt out. To keep Node.js compatibility switched off on a newer compatibility date, specify both `no_nodejs_compat` and `no_nodejs_compat_v2`, since each flag has its own default. `@cloudflare/vitest-pool-workers` needs `nodejs_compat_v2` for its own test runner, so it continues to override a project that opts out of it. On a compatibility date that enables the flag anyway, it now drops the opt-out rather than adding the flag back, which workerd would reject — previously this stopped such a project from running any tests at all. `wrangler types` also no longer attributes its `@types/node` suggestion to "the `nodejs_compat` flag", which it can now make for Workers that do not set the flag at all. ### Patch Changes - [`#15123`](https://github.com/cloudflare/workers-sdk/pull/15123) [`d0c976c`](https://github.com/cloudflare/workers-sdk/commit/d0c976c04ad890fcef56305ded11f1405e89273e) Thanks [`@dependabot`](https://github.com/apps/dependabot)! - Update dependencies of "miniflare", "wrangler" The following dependency versions have been updated: | Dependency | From | To | | ------------------------- | ------------- | ------------- | | `@cloudflare/workers-types` | ^5.20260804.1 | ^5.20260811.1 | | workerd | 1.20260804.1 | 1.20260811.1 | - [`#15148`](https://github.com/cloudflare/workers-sdk/pull/15148) [`0b82b15`](https://github.com/cloudflare/workers-sdk/commit/0b82b1574b3327681a0091716ed274c8f0544a48) Thanks [`@jamesopstad`](https://github.com/jamesopstad)! - Ignore a `nodejs_compat` compatibility flag that the compatibility date already enables workerd rejects a compatibility flag that its compatibility date enables by default, so a Worker configured with both a compatibility date of `2026-08-04` or later **and** `nodejs_compat` failed to start locally with "The compatibility flag nodejs_compat became the default as of 2026-08-04 so does not need to be specified anymore".

These updates apply to all Workers globally and should never cause a Worker that is already deployed to stop functioning. Sometimes, though, some changes may be backwards-incompatible. In particular, there might be bugs in the runtime API that existing Workers may inadvertently depend upon. Cloudflare implements bug fixes that new Workers can opt into while existing Workers will continue to see the buggy behavior to prevent breaking deployed Workers. The compatibility date and flags are how you, as a developer, opt into these runtime changes. Compatibility flags will often have a date in which they are enabled by default, and so, by specifying a `compatibility_date` for your Worker, you can quickly enable all of these various compatibility flags up to, and including, that date. ## Setting compatibility date When you start your project, you should always set `compatibility_date` to the current date. You should occasionally update the `compatibility_date` field. When updating, you should refer to the compatibility flags page to find out what has changed, and you should be careful to test your Worker to see if the changes affect you, updating your code as necessary. The new compatibility date takes effect when you next run the `npx wrangler deploy` command. There is no need to update your `compatibility_date` if you do not want to. The Workers runtime will support old compatibility dates forever. If, for some reason, Cloudflare finds it is necessary to make a change that will break live Workers, Cloudflare will actively contact affected developers. That said, Cloudflare aims to avoid this if at all possible. However, even though you do not need to update the `compatibility_date` field, it is a good practice to do so for two reasons: 1. Sometimes, new features can only be made available to Workers that have a current `compatibility_date`. To access the latest features, you need to stay up-to-date. 2. Generally, other than the compatibility flags page, the Workers documentation may only describe the current `compatibility_date`, omitting information about historical behavior. If your Worker uses an old `compatibility_date`, you will need to continuously refer to the compatibility flags page in order to check if any of the APIs you are using have changed. #### Via Wrangler The compatibility date can be set in a Worker&`#39`;s Wrangler configuration file. wrangler.jsonc wrangler.toml ``` { // Opt into backwards-incompatible changes through April 5, 2022. "compatibility_date": "2022-04-05" } ``` Copy code to clipboard ``` compatibility_date = "2022-04-05" ``` Copy code to clipboard #### Via the Cloudflare Dashboard When a Worker is created through the Cloudflare Dashboard, the compatibility date is automatically set to the current date. The compatibility date can be updated in the Workers settings on the Cloudflare dashboard ↗. #### Via the Cloudflare API The compatibility date can be set when uploading a Worker using the Workers Script API or Workers Versions API in the request body&`#39`;s `metadata` field. If a compatibility date is not specified on upload via the API, it defaults to the oldest compatibility date, before any flags took effect (2021-11-02). When creating new Workers, it is highly recommended to set the compatibility date to the current date when uploading via the API.

Remove the redundant nodejs_compat flag.

The Prisma v7 TCP path still requires Node.js compatibility. With compatibility_date: "2026-08-23", Workers enables that compatibility automatically, and current Wrangler drops the redundant flag. New configurations should omit it. Update the prerequisite and section title to describe the compatibility date instead.

Proposed fix
-- set `nodejs_compat` in `wrangler.jsonc`
+- set a compatibility date of `2026-08-23` or later in `wrangler.jsonc`

-#### 3. Set `nodejs_compat` in `wrangler.jsonc`
+#### 3. Set the compatibility date in `wrangler.jsonc`

-  "compatibility_flags": [
-    "nodejs_compat"
-  ],
   "compatibility_date": "2026-08-23"
