Release Notes

evanw/esbuild (esbuild)

v0.27.3

Compare Source

• Preserve URL fragments in data URLs (#​4370)

  Consider the following HTML, CSS, and SVG:

  • index.html:

    <!DOCTYPE html>
    <html>
      <head><link rel="stylesheet" href="icons.css"></head>
      <body><div class="triangle"></div></body>
    </html>

  • icons.css:

    .triangle {
      width: 10px;
      height: 10px;
      background: currentColor;
      clip-path: url(./triangle.svg#x);
    }

  • triangle.svg:

    <svg xmlns="http://www.w3.org/2000/svg">
      <defs>
        <clipPath id="x">
          <path d="M0 0H10V10Z"/>
        </clipPath>
      </defs>
    </svg>

  The CSS uses a URL fragment (the #x) to reference the clipPath element in the SVG file. Previously esbuild's CSS bundler didn't preserve the URL fragment when bundling the SVG using the dataurl loader, which broke the bundled CSS. With this release, esbuild will now preserve the URL fragment in the bundled CSS:

  /* icons.css */
  .triangle {
    width: 10px;
    height: 10px;
    background: currentColor;
    clip-path: url('data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg"><defs><clipPath id="x"><path d="M0 0H10V10Z"/></clipPath></defs></svg>#x');
  }

• Parse and print CSS @scope rules (#​4322)

  This release includes dedicated support for parsing @scope rules in CSS. These rules include optional "start" and "end" selector lists. One important consequence of this is that the local/global status of names in selector lists is now respected, which improves the correctness of esbuild's support for CSS modules. Minification of selectors inside @scope rules has also improved slightly.

  Here's an example:

  /* Original code */
  @​scope (:global(.foo)) to (:local(.bar)) {
    .bar {
      color: red;
    }
  }
  
  /* Old output (with --loader=local-css --minify) */
  @​scope (:global(.foo)) to (:local(.bar)){.o{color:red}}
  
  /* New output (with --loader=local-css --minify) */
  @​scope(.foo)to (.o){.o{color:red}}

• Fix a minification bug with lowering of for await (#​4378, #​4385)

  This release fixes a bug where the minifier would incorrectly strip the variable in the automatically-generated catch clause of lowered for await loops. The code that generated the loop previously failed to mark the internal variable references as used.

• Update the Go compiler from v1.25.5 to v1.25.7 (#​4383, #​4388)
