Bump esbuild from 0.8.24 to 0.25.0

[dependabot]

Bumps esbuild from 0.8.24 to 0.25.0.

Release notes

Sourced from esbuild's releases.

v0.25.0

This release deliberately contains backwards-incompatible changes. To avoid automatically picking up releases like this, you should either be pinning the exact version of esbuild in your package.json file (recommended) or be using a version range syntax that only accepts patch upgrades such as ^0.24.0 or ~0.24.0. See npm's documentation about semver for more information.

• Restrict access to esbuild's development server (GHSA-67mh-4wv8-2f99)

  This change addresses esbuild's first security vulnerability report. Previously esbuild set the Access-Control-Allow-Origin header to * to allow esbuild's development server to be flexible in how it's used for development. However, this allows the websites you visit to make HTTP requests to esbuild's local development server, which gives read-only access to your source code if the website were to fetch your source code's specific URL. You can read more information in the report.

  Starting with this release, CORS will now be disabled, and requests will now be denied if the host does not match the one provided to --serve=. The default host is 0.0.0.0, which refers to all of the IP addresses that represent the local machine (e.g. both 127.0.0.1 and 192.168.0.1). If you want to customize anything about esbuild's development server, you can put a proxy in front of esbuild and modify the incoming and/or outgoing requests.

  In addition, the serve() API call has been changed to return an array of hosts instead of a single host string. This makes it possible to determine all of the hosts that esbuild's development server will accept.

  Thanks to @​sapphi-red for reporting this issue.

• Delete output files when a build fails in watch mode (#3643)

  It has been requested for esbuild to delete files when a build fails in watch mode. Previously esbuild left the old files in place, which could cause people to not immediately realize that the most recent build failed. With this release, esbuild will now delete all output files if a rebuild fails. Fixing the build error and triggering another rebuild will restore all output files again.

• Fix correctness issues with the CSS nesting transform (#3620, #3877, #3933, #3997, #4005, #4037, #4038)

  This release fixes the following problems:

  • Naive expansion of CSS nesting can result in an exponential blow-up of generated CSS if each nesting level has multiple selectors. Previously esbuild sometimes collapsed individual nesting levels using :is() to limit expansion. However, this collapsing wasn't correct in some cases, so it has been removed to fix correctness issues.

    /* Original code */
    .parent {
      > .a,
      > .b1 > .b2 {
        color: red;
      }
    }
    /* Old output (with --supported:nesting=false) */
    .parent > :is(.a, .b1 > .b2) {
    color: red;
    }
    /* New output (with --supported:nesting=false) */
    .parent > .a,
    .parent > .b1 > .b2 {
    color: red;
    }

    Thanks to @​tim-we for working on a fix.

  • The & CSS nesting selector can be repeated multiple times to increase CSS specificity. Previously esbuild ignored this possibility and incorrectly considered && to have the same specificity as &. With this release, this should now work correctly:

    /* Original code (color should be red) */

0.8.28

• Add a --summary flag that prints helpful information after a build (#631)

  Normally esbuild's CLI doesn't print anything after doing a build if nothing went wrong. This allows esbuild to be used as part of a more complex chain of tools without the output cluttering the terminal. However, sometimes it is nice to have a quick overview in your terminal of what the build just did. You can now add the --summary flag when using the CLI and esbuild will print a summary of what the build generated. It looks something like this:

  $ ./esbuild --summary --bundle src/Three.js --outfile=build/three.js --sourcemap
  build/three.js      1.0mb ⚠️
  
  build/three.js.map  1.8mb
  ⚡ Done in 43ms
  
  

• Keep unused imports in TypeScript code in one specific case (#604)

  The official TypeScript compiler always removes imported symbols that aren't used as values when converting TypeScript to JavaScript. This is because these symbols could be types and not removing them could result in a run-time module instantiation failure because of missing exports. This even happens when the tsconfig.json setting "importsNotUsedAsValues" is set to "preserve". Doing this just keeps the import statement itself but confusingly still removes the imports that aren't used as values.

  Previously esbuild always exactly matched the behavior of the official TypeScript compiler regarding import removal. However, that is problematic when trying to use esbuild to compile a partial module such as when converting TypeScript to JavaScript inside a file written in the Svelte programming language. Here is an example:

  <script lang="ts">
    import Counter from './Counter.svelte';
    export let name: string = 'world';
  </script>
  <main>
    <h1>Hello {name}!</h1>
    <Counter />
  </main>

  The current Svelte compiler plugin for TypeScript only provides esbuild with the contents of the <script> tag so to esbuild, the import Counter appears to be unused and is removed.

  In this release, esbuild deliberately deviates from the behavior of the official TypeScript compiler if all of these conditions are met:

  • The "importsNotUsedAsValues" field in tsconfig.json must be present and must not be set to "remove". This is necessary because this is the only case where esbuild can assume that all imports are values instead of types. Any imports that are types will cause a type error when the code is run through the TypeScript type checker. To import types when the importsNotUsedAsValues setting is active, you must use the TypeScript-specific import type syntax instead.

  • You must not be using esbuild as a bundler. When bundling, esbuild needs to assume that it's not seeing a partial file because the bundling process requires renaming symbols to avoid cross-file name collisions.

  • You must not have identifier minification enabled. It's useless to preserve unused imports in this case because referencing them by name won't work anyway. And keeping the unused imports would be counter-productive to minification since they would be extra unnecessary data in the output file.

  This should hopefully allow esbuild to be used as a TypeScript-to-JavaScript converter for programming languages such as Svelte, at least in many cases. The build pipeline in esbuild wasn't designed for compiling partial modules and this still won't be a fully robust solution (e.g. some variables may be renamed to avoid name collisions in rare cases). But it's possible that these cases are very unlikely to come up in practice. Basically this change to keep unused imports in this case should be useful at best and harmless at worst.
