User description

Bumps esbuild from 0.25.10 to 0.27.0.

Release notes

Sourced from esbuild's releases.

v0.27.0

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 ^0.26.0 or ~0.26.0. See npm's documentation about semver for more information.

  • Use Uint8Array.fromBase64 if available (#4286)

    With this release, esbuild's binary loader will now use the new Uint8Array.fromBase64 function unless it's unavailable in the configured target environment. If it's unavailable, esbuild's previous code for this will be used as a fallback. Note that this means you may now need to specify target when using this feature with Node (for example --target=node22) unless you're using Node v25+.

  • Update the Go compiler from v1.23.12 to v1.25.4 (#4208, #4311)

    This raises the operating system requirements for running esbuild:

    • Linux: now requires a kernel version of 3.2 or later
    • macOS: now requires macOS 12 (Monterey) or later

v0.26.0

  • Enable trusted publishing (#4281)

    GitHub and npm are recommending that maintainers for packages such as esbuild switch to trusted publishing. With this release, a VM on GitHub will now build and publish all of esbuild's packages to npm instead of me. In theory.

    Unfortunately there isn't really a way to test that this works other than to do it live. So this release is that live test. Hopefully this release is uneventful and is exactly the same as the previous one (well, except for the green provenance attestation checkmark on npm that happens with trusted publishing).

v0.25.12

  • 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:

CodeAnt-AI Description

Upgrade esbuild to 0.27.0 for app frontend builds

What Changed

  • The app's devDependency for the frontend bundler was bumped from esbuild 0.25.10 to 0.27.0; package-lock was updated so installs will fetch the 0.27.0 platform binaries.
  • Local and CI build/watch scripts now run with esbuild 0.27.0, which can change bundling output or build behavior because the upstream release includes breaking changes.
  • Developers should verify frontend builds after updating and adjust build targets or environment if any compatibility issues appear.

Impact

✅ Frontend builds use esbuild 0.27.0
✅ npm install pulls esbuild 0.27.0 platform binaries
✅ Potential bundling or build compatibility changes requiring local verification
