cloudflare/workers-sdk wrangler@2.11.0

on GitHub

Minor Changes

• #2651 a9adfbe7 Thanks @penalosa! - Previously, wrangler dev would not work if the root of your zone wasn't behind Cloudflare. This behaviour has changed so that now only the route which your Worker is exposed on has to be behind Cloudflare.

• #2708 b3346cfb Thanks @Skye-31! - Feat: Pages now supports Proxying (200 status) redirects in it's _redirects file

  This will look something like the following, where a request to /users/123 will appear as that in the browser, but will internally go to /users/[id].html.

  /users/:id /users/[id] 200
  

Patch Changes

• #2766 7912e63a Thanks @mrbbot! - fix: correctly detect service-worker format when using typeof module

  Wrangler automatically detects whether your code is a modules or service-worker format Worker based on the presence of a default export. This check currently works by building your entrypoint with esbuild and looking at the output metafile.

  Previously, we were passing format: "esm" to esbuild when performing this check, which enables format conversion. This may introduce export default into the built code, even if it wasn't there to start with, resulting in incorrect format detections.

  This change removes format: "esm" which disables format conversion when bundling is disabled. See https://esbuild.github.io/api/#format for more details.

• #2780 80f1187a Thanks @GregBrimble! - fix: Ensure we don't mangle internal constructor names in the wrangler bundle when building with esbuild

  Undici changed how they referenced FormData, which meant that when used in our bundle process, we were failing to upload multipart/form-data bodies. This affected wrangler pages publish and wrangler publish.

• #2720 de0cb57a Thanks @JacobMGEvans! - Fix: Upgraded to ES2022 for improved compatibility
  Upgraded worker code target version from ES2020 to ES2022 for better compatibility and unblocking of a workaround related to issue #2029. The worker runtime now uses the same V8 version as recent Chrome and is 99% ES2016+ compliant. The only thing we don't support on the Workers runtime, the remaining 1%, is the ES2022 RegEx feature as seen in the compat table for the latest Chrome version.

• #2771 4ede044e Thanks @mrbbot! - chore: upgrade miniflare to 2.12.1 and @miniflare/tre to 3.0.0-next.10
