Release Notes

evanw/esbuild (esbuild)

v0.25.12

Compare Source

  • Fix a minification regression with CSS media queries (#​4315)

    The previous release introduced support for parsing media queries which unintentionally introduced a regression with the removal of duplicate media rules during minification. Specifically the grammar for @media <media-type> and <media-condition-without-or> { ... } was missing an equality check for the <media-condition-without-or> part, so rules with different suffix clauses in this position would incorrectly compare equal and be deduplicated. This release fixes the regression.

  • Update the list of known JavaScript globals (#​4310)

    This release updates esbuild's internal list of known JavaScript globals. These are globals that are known to not have side-effects when the property is accessed. For example, accessing the global Array property is considered to be side-effect free but accessing the global scrollY property can trigger a layout, which is a side-effect. This is used by esbuild's tree-shaking to safely remove unused code that is known to be side-effect free. This update adds the following global properties:

    From ES2017:

    • Atomics
    • SharedArrayBuffer

    From ES2020:

    • BigInt64Array
    • BigUint64Array

    From ES2021:

    • FinalizationRegistry
    • WeakRef

    From ES2025:

    • Float16Array
    • Iterator

    Note that this does not indicate that constructing any of these objects is side-effect free, just that accessing the identifier is side-effect free. For example, this now allows esbuild to tree-shake classes that extend from Iterator:

    // This can now be tree-shaken by esbuild:
    class ExampleIterator extends Iterator {}
  • Add support for the new @view-transition CSS rule (#​4313)

    With this release, esbuild now has improved support for pretty-printing and minifying the new @view-transition rule (which esbuild was previously unaware of):

    /* Original code */
    @&#8203;view-transition {
      navigation: auto;
      types: check;
    }
    
    /* Old output */
    @&#8203;view-transition { navigation: auto; types: check; }
    
    /* New output */
    @&#8203;view-transition {
      navigation: auto;
      types: check;
    }

    The new view transition feature provides a mechanism for creating animated transitions between documents in a multi-page app. You can read more about view transition rules here.

    This change was contributed by @​yisibl.

  • Trim CSS rules that will never match

    The CSS minifier will now remove rules whose selectors contain :is() and :where() as those selectors will never match. These selectors can currently be automatically generated by esbuild when you give esbuild nonsensical input such as the following:

    /* Original code */
    div:before {
      color: green;
      &.foo {
        color: red;
      }
    }
    
    /* Old output (with --supported:nesting=false --minify) */
    div:before{color:green}:is().foo{color:red}
    
    /* New output (with --supported:nesting=false --minify) */
    div:before{color:green}

    This input is nonsensical because CSS nesting is (unfortunately) not supported inside of pseudo-elements such as :before. Currently esbuild generates a rule containing :is() in this case when you tell esbuild to transform nested CSS into non-nested CSS. I think it's reasonable to do that as it sort of helps explain what's going on (or at least indicates that something is wrong in the output). It shouldn't be present in minified code, however, so this release now strips it out.

v0.25.11

Compare Source

  • Add support for with { type: 'bytes' } imports (#​4292)

    The import bytes proposal has reached stage 2.7 in the TC39 process, which means that although it isn't quite recommended for implementation, it's generally approved and ready for validation. Furthermore it has already been implemented by Deno and Webpack. So with this release, esbuild will also add support for this. It behaves exactly the same as esbuild's existing binary loader. Here's an example:

    import data from './image.png' with { type: 'bytes' }
    const view = new DataView(data.buffer, 0, 24)
    const width = view.getInt32(16)
    const height = view.getInt32(20)
    console.log('size:', width + '\xD7' + height)
  • Lower CSS media query range syntax (#​3748, #​4293)

    With this release, esbuild will now transform CSS media query range syntax into equivalent syntax using min-/max- prefixes for older browsers. For example, the following CSS:

    @&#8203;media (640px <= width <= 960px) {
      main {
        display: flex;
      }
    }

    will be transformed like this with a target such as --target=chrome100 (or more specifically with --supported:media-range=false if desired):

    @&#8203;media (min-width: 640px) and (max-width: 960px) {
      main {
        display: flex;
      }
    }

    Bump esbuild from 0.25.10 to 0.25.11. The update appears safe given its minor nature and added features. Confirm that new behaviors (e.g., import bytes support) don't affect our build.
