Nock 14 disableNetConnect Node fetch undici support official documentation

💡 Result:

Nock version 14 introduces support for native Node.js fetch and includes basic support for Undici, allowing you to use Nock's mocking capabilities with these modern HTTP clients [1][2][3]. Regarding the specific components of your query: 1. disableNetConnect Support: Nock's disableNetConnect() function is the standard method for forbidding unmocked HTTP requests [4][5]. In Nock v14, this functionality is designed to work with the updated interception logic that supports native fetch [6]. When disableNetConnect() is active, any request made to a host that is not explicitly mocked will trigger a NetConnectNotAllowedError [4][5]. 2. Undici Support: While Nock traditionally intercepted requests at the Node.js built-in http module level—which Undici bypasses by using the net module directly [7]—Nock v14 added basic support for Undici [3]. This is achieved by allowing Nock to act as a dispatcher within the Undici ecosystem [3]. 3. Official Documentation: Official guidance on these features is primarily found in the Nock repository's pull request descriptions, release notes, and source code [1][2][3]. Because Undici and native fetch operate differently than traditional http requests, Nock's integration with them is documented through these repository updates rather than a static, separate documentation page [1][8][3]. For users requiring advanced Undici mocking, the recommended approach remains using Undici's native MockAgent when possible, as it is purpose-built for that library [8][9][7]. If you are using Nock to support legacy and modern fetch/undici requests simultaneously, ensure you are on a recent v14 release [2][10].

Nock v14 Undici custom dispatcher Agent disableNetConnect native fetch interception

💡 Result:

Nock v14 introduced support for native fetch [1] by migrating to @mswjs/interceptors for its interception logic [2]. While Nock v14 has added basic, experimental support for intercepting Undici requests [3], it does not fully replace Undici's native mocking capabilities or handle all custom dispatcher scenarios [4][5]. Regarding your specific requirements: 1. Undici Custom Dispatcher/Agent Interception: Nock v14 provides a NockAgent that attempts to intercept Undici requests by setting the global dispatcher [3]. However, this mechanism can be bypassed if an explicit custom dispatcher or agent is provided to the fetch or Undici request call [4]. In such cases, Nock's global interceptor is ignored because the request bypasses the global dispatcher that Nock has wrapped [4]. 2. disableNetConnect: Nock's nock.disableNetConnect is primarily designed for the standard Node.js http/https modules [6]. Because Undici operates differently—often by design ignoring global monkey-patching in favor of its own dispatcher-based model—nock.disableNetConnect does not reliably block outgoing network requests made through Undici [6][7]. Recommended Approach: For Undici-based code, particularly when using custom dispatchers or agents, it is best practice to use Undici's built-in MockAgent [6][5]. This provides native, reliable mocking and network control without the limitations of Nock's interception layer: const { MockAgent, setGlobalDispatcher } = require('undici'); const mockAgent = new MockAgent; mockAgent.disableNetConnect; // Reliably disables network for Undici requests [8] setGlobalDispatcher(mockAgent); // To handle custom clients/pools, use the mock agent to get an interceptor const mockPool = mockAgent.get('http://example.com'); mockPool.intercept({ path: '/test', method: 'GET' }).reply(200, { data: 'ok' }); If you must use Nock, be aware that it currently supports interception primarily at the global level [3]. If your application architecture requires passing explicit custom dispatchers, you may need to use a manual stubbing workaround (such as using Reflect to force the use of the Nock-managed dispatcher) [4], though this is not officially supported and may be brittle.

Block real network access in KimiCode tests.

OpenAiHandler.customFetch passes an explicit undici.Agent, which bypasses Nock's global dispatcher. Therefore, nock.disableNetConnect() does not protect the request-consuming tests that rely on the forwarding mock. Install a default rejecting globalThis.fetch stub and override it only in tests that need responses, or use an Undici MockAgent.

Align the timeout comment with DEFAULT_TIMEOUT_MS.

DEFAULT_TIMEOUT_MS evaluates to 60 minutes, but the comment states 50 minutes. Update the comment or change the constant if 50 minutes is the intended default.

Suggested correction

+// 60 min default request timeout

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
