v0.25.5

• Fix a regression with browser in package.json (#4187)

  The fix to #4144 in version 0.25.3 introduced a regression that caused browser overrides specified in package.json to fail to override relative path names that end in a trailing slash. That behavior change affected the axios@0.30.0 package. This regression has been fixed, and now has test coverage.

• Add support for certain keywords as TypeScript tuple labels (#4192)

  Previously esbuild could incorrectly fail to parse certain keywords as TypeScript tuple labels that are parsed by the official TypeScript compiler if they were followed by a ? modifier. These labels included function, import, infer, new, readonly, and typeof. With this release, these keywords will now be parsed correctly. Here's an example of some affected code:

  type Foo = [
    value: any,
    readonly?: boolean, // This is now parsed correctly
  ]
  

• Add CSS prefixes for the stretch sizing value (#4184)

  This release adds support for prefixing CSS declarations such as div { width: stretch }. That CSS is now transformed into this depending on what the --target= setting includes:

  div {
    width: -webkit-fill-available;
    width: -moz-available;
    width: stretch;
  }
  

v0.25.4

• Add simple support for CORS to esbuild's development server (#4125)

  Starting with version 0.25.0, esbuild's development server is no longer configured to serve cross-origin requests. This was a deliberate change to prevent any website you visit from accessing your running esbuild development server. However, this change prevented (by design) certain use cases such as "debugging in production" by having your production website load code from localhost where the esbuild development server is running.

  To enable this use case, esbuild is adding a feature to allow Cross-Origin Resource Sharing (a.k.a. CORS) for simple requests. Specifically, passing your origin to the new cors option will now set the Access-Control-Allow-Origin response header when the request has a matching Origin header. Note that this currently only works for requests that don't send a preflight OPTIONS request, as esbuild's development server doesn't currently support OPTIONS requests.

  Some examples:

  • CLI:

    esbuild --servedir=. --cors-origin=https://example.com
    

  • JS:

    const ctx = await esbuild.context({})
    await ctx.serve({
      servedir: '.',
      cors: {
