mswjs/msw v0.36.0

on GitHub

Breaking changes

• Uses path-to-regexp for URL matching (#691, #888). This makes the path matching experience identical to such in ExpressJS, and enabled various new features:
  • Optional path segments (/foo/bar?);
  • Repeating groups (/foo/bar+).
• Request path parameters are now annotated as ambiguous string | string[] (#999).
• The RequestParams generic now follows the RequestBodyType generic, changing its order (#999):

rest.post<RequestBodyType, RequestParams, ResponseBodyType>() {}

• Removes the RequestParams type (#999). Please use the PathParams type instead.

- import { RequestParams } from 'msw'
+ import { PathParams } from 'msw'

• Relative requests are now resolved against document.baseURI (previously location.origin) in a browser-like environments (#1007, #1008).

Features

• Adds a new rest.all() request handler (#896). This handler captures all REST API requests regardless of method.

import { rest } from 'msw'

rest.all('/api/*', (req, res, ctx) => {
  // Intercepts all requests to "/api/*"
  // regardless of their method.
})

• Supports encoded request path components (#980).
• Supports mocking GraphQL extensions (#981).

graphql.query('GetUser', (req, res, ctx) => {
  return res(
    ctx.extensions({
      message: 'Mocked extension',
      tracking: { version: '1.2.3' }
    })
  )
})

• Exports SetupWorkerApi and SetupServerApi from the browser and Node.js modules respectively (#994).

Bug fixes

• Specifies typescript as a peerDependency to control supported TypeScript versions (#985).
• Fixes an issue that resulted in graphql.operation handler producing a warning unable to intercept anonymous operations (#918, #904).
• Locks inquirer dependency version to 8.1.5 to propagate the fix for the Unexpected token “?” issue when using MSW CLI (#917).
• Fixes an issue that resulted in the TypeError: Failed to execute 'XXX' on 'Response': body stream already read error when reading the original response body in the fallback mode (mswjs/interceptors#152).

Internal

• Lists @mswjs/cookies and @mswjs/interceptors as external packages so that their updates propagate to you automatically upon new installations of msw.
• Updates dependencies.
