Features

  • ⚡️ Add custom Vitest testing environment. This behaves almost identically to the Jest environment. However, isolated storage must be installed manually in each test file. Call the setupMiniflareIsolatedStorage() global function and use the returned describe function instead of the regular describe/suite functions imported from vitest. See ⚡️ Vitest Environment for more details.
  • 🌐 Populate Workers Sites __STATIC_CONTENT_MANIFEST with site files instead of an empty object. Miniflare will still disable caching of Workers Sites files to ensure the most up-to-date files are always returned. Closes issues #233, #326 and cloudflare/wrangler2#1632. Thanks @ItalyPaleAle, @Skye-31, @CraigglesO, @Hexstream and @PolariTOON.
  • ⏱ Add global getMiniflareWaitUntil() method and ExecutionContext class to the Jest and Vitest testing environments. This can be used to await the results of waitUntiled Promises in tests. See 🤹️ Jest Environment and ⚡️ Vitest Environment for more details. Closes issue #202, thanks @jamesarosen and @CraigglesO for the PR.
  • ⏳ Match Web Streams implementations with Workers runtime, closes issue #168, thanks @leviwolfe:
    • Add support for the non-standard IdentityTransformStream class.
    • Add support for the streams_enable_constructors compatibility flag. ReadableStream and WritableStream constructors will throw unless this flag is enabled. ReadableByteStreamController, ReadableStreamBYOBRequest, ReadableStreamDefaultController and WritableStreamDefaultController will only be included in the sandbox if this flag is enabled.
    • Add support for the transformstream_enable_standard_constructor compatibility flag. TransformStream will behave like IdentityTransformStream if this isn't enabled, ignoring custom transformers. If transformstream_enable_standard_constructor is set, but streams_enable_constructors isn't, the TransformStream constructor will throw. TransformStreamDefaultController will only be included in the sandbox if both flags are enabled.
    • Add support for BYOB reads to the non-standard FixedLengthStream class.
  • 🇬🇧 Add support for Queues. Docs coming soon™... 👀
  • 🙉 Allow calls to addEventListener, removeEventListener and dispatchEvent in modules mode. Please note, calling addEventListener with a special event type (e.g. fetch, scheduled) will log a warning prompting you to use the export default syntax. Closes issue #207, thanks @Electroid.
  • 🍟 Add experimental and highly-inaccurate request CPU time measurements. These are not representative of deployed worker performance, should only be used for relative comparisons, and may be removed in the future. Enable measurements with the --inaccurate-cpu/[miniflare] inaccurate_cpu/inaccurateCpu option. Closes issue #161. Thanks @alexandernst and @y21.
  • 🦄 Automatically enable watch mode when live_reload = true is set in wrangler.toml.

Fixes

  • Return Responses with immutable headers from fetches to Durable Objects and service bindings. Closes issue #346, thanks @Cherry.
  • Fix CryptoKey#algorithm.name property of NODE-ED25519 keys. Closes issue panva/jose#446, thanks @ItalyPaleAle.
  • Disable automatic insertion of Sec-WebSocket-Protocol header. Closes issue #179, thanks @aboodman and @grgbkr.
  • Return Content-Length header is custom Content-Encoding is specified. Closes issue #313, thanks @vlovich.
  • Require "automatic" instead of "auto" for the encodeBody option when constructing Requests. Closes issue #357, thanks @GregBrimble for the PR.
  • Remove request.cf.cacheTtl/request.cf.cacheTtlByStatus support from the Cache API to match the behaviour of the Workers runtime, which only supports request.cf.cacheKey.
