chore(deps): bump esbuild and vitest in /cloudflare-og-worker

[dependabot]

Bumps esbuild to 0.25.12 and updates ancestor dependency vitest. These dependencies need to be updated together.

Updates esbuild from 0.21.5 to 0.25.12

Release notes

Sourced from esbuild's releases.

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:
  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 */
  @view-transition {
    navigation: auto;
    types: check;
  }
  /* Old output */
  @​view-transition { navigation: auto; types: check; }
  /* New output */
  @​view-transition {
  navigation: auto;
  types: check;

Changelog

Sourced from esbuild's changelog.

Changelog: 2024

This changelog documents all esbuild versions published in the year 2024 (versions 0.19.12 through 0.24.2).

0.24.2

• Fix regression with --define and import.meta (#4010, #4012, #4013)

  The previous change in version 0.24.1 to use a more expression-like parser for define values to allow quoted property names introduced a regression that removed the ability to use --define:import.meta=.... Even though import is normally a keyword that can't be used as an identifier, ES modules special-case the import.meta expression to behave like an identifier anyway. This change fixes the regression.

  This fix was contributed by @​sapphi-red.

0.24.1

• Allow es2024 as a target in tsconfig.json (#4004)

  TypeScript recently added es2024 as a compilation target, so esbuild now supports this in the target field of tsconfig.json files, such as in the following configuration file:

  {
    "compilerOptions": {
      "target": "ES2024"
    }
  }

  As a reminder, the only thing that esbuild uses this field for is determining whether or not to use legacy TypeScript behavior for class fields. You can read more in the documentation.

  This fix was contributed by @​billyjanitsch.

• Allow automatic semicolon insertion after get/set

  This change fixes a grammar bug in the parser that incorrectly treated the following code as a syntax error:

  class Foo {
    get
    *x() {}
    set
    *y() {}
  }

  The above code will be considered valid starting with this release. This change to esbuild follows a similar change to TypeScript which will allow this syntax starting with TypeScript 5.7.

• Allow quoted property names in --define and --pure (#4008)

  The define and pure API options now accept identifier expressions containing quoted property names. Previously all identifiers in the identifier expression had to be bare identifiers. This change now makes --define and --pure consistent with --global-name, which already supported quoted property names. For example, the following is now possible:

Pull Request Review - PR #703

Summary

This PR updates esbuild from 0.21.5 to 0.25.12 and vitest from 2.1.9 to 4.0.15 in the cloudflare-og-worker package. These are dependency updates triggered by Dependabot for security and feature improvements.

---

✅ Code Quality & Best Practices

Positive aspects:

• Automated dependency management: Dependabot-generated PR ensures timely updates
• Package scope: Changes are isolated to the Cloudflare worker subdirectory (cloudflare-og-worker/), minimizing impact on the main application
• Lock file updated: Both package.json and package-lock.json are properly synchronized

Observations:

• The PR updates from Vitest 2.x to 4.x, which is a major version jump (2 major versions)
• esbuild update spans from 0.21.5 to 0.27.2 (based on lock file changes), crossing multiple minor versions

🔍 Potential Issues & Breaking Changes

Critical: Vitest v3.0 and v4.0 Breaking Changes

Jumping from Vitest 2.1.9 → 4.0.15 skips v3.0 entirely. Based on Vitest's release history, here are potential breaking changes to watch for:

1. Test API Changes: Major versions often introduce breaking changes to test APIs, assertion syntax, or configuration options
2. Node.js version requirements: Vitest 4.x may require a newer Node.js version (the esbuild engine requirement increased from Node >=12 to >=18)
3. TypeScript compatibility: Vitest 4.x may have stricter TypeScript requirements
4. Mock/spy behavior changes: Major versions often refine mocking APIs

Recommendation:

• ✅ Run the test suite to verify compatibility:

  cd cloudflare-og-worker && npm test

• ✅ Check the Vitest migration guides for v3.0 and v4.0
• ✅ Review test files (src/html.test.ts, src/crawler.test.ts, src/parser.test.ts) to ensure they still pass

esbuild Engine Requirement Change

The lock file shows esbuild platform packages now require Node.js >=18 (previously >=12). This is a significant change:

Action required:

• ✅ Verify the CI/CD pipeline and deployment environment use Node.js 18+
• ✅ Check if package.json needs an explicit engines field to enforce this requirement
• ✅ Confirm Cloudflare Workers deployment is unaffected (Workers use V8 isolates, not Node.js)

---

🛡️ Security Concerns

Positive:

• Updating dependencies addresses potential security vulnerabilities in older versions
• esbuild 0.25.12 includes fixes for CSS media query deduplication (regression from 0.25.11)
• Vitest 4.x includes numerous bug fixes and security improvements

Recommendations:

• ✅ Run npm audit to check for any remaining vulnerabilities
• ✅ Review the full changelogs for security-related fixes:
  • esbuild releases
  • vitest releases

---

⚡ Performance Considerations

esbuild improvements (0.21.5 → 0.25.12):

• Better tree-shaking with updated JavaScript globals list (ES2017-ES2025)
• CSS minification fixes for @media rules
• Support for @view-transition CSS rule
• Various parser and bundler performance optimizations

vitest improvements (2.1.9 → 4.0.15):

• New experimental caching features (v4.0.15)
• Import duration breakdown reporting
• Coverage improvements for Istanbul provider
• Better worker pool management

Expected impact:

• ✅ Faster build times for the Cloudflare worker
• ✅ Potentially faster test execution
• ⚠️ First build after update may take longer due to cache invalidation

---

🧪 Test Coverage

Current test files:

• src/html.test.ts - HTML generation and XSS prevention (44 tests based on file content)
• src/crawler.test.ts - Web crawling logic
• src/parser.test.ts - Metadata parsing

Verification needed:

• ✅ All existing tests must pass with new Vitest version
• ✅ Test coverage should remain stable or improve
• ✅ Check for any new deprecation warnings in test output

---

📝 Documentation & Changelog

Missing:

• ⚠️ No CHANGELOG.md entry for this dependency update

Recommendation:
According to CLAUDE.md, the changelog should be updated for significant changes. While dependency updates are often omitted, a major version jump in Vitest warrants documentation:

## [Unreleased] - YYYY-MM-DD

### Changed
- **Dependency updates** (`cloudflare-og-worker/package.json`):
  - Updated esbuild from 0.21.5 to 0.25.12 for latest bundling improvements
  - Updated vitest from 2.1.9 to 4.0.15 (major version upgrade)
  - Note: Requires Node.js 18+ in development environment

---

🔧 Additional Checks

Before merging, please verify:

1. CI/CD Pipeline Status: Ensure all automated checks pass
2. Test Execution:

   cd cloudflare-og-worker
   npm install
   npm test
   npm run typecheck

3. Build Verification:

   npm run deploy:staging  # Test deployment to staging environment

4. Node.js Version: Confirm development/CI environment uses Node.js 18+

---

📊 Overall Assessment

Risk Level: ⚠️ MEDIUM

• Low risk for security vulnerabilities (dependency updates are good)
• Medium risk for breaking changes (major version jump in Vitest)
• Low risk for runtime issues (changes are dev dependencies only)

Recommendation: ✅ APPROVE with verification

This PR should be merged after confirming:

1. All tests pass with Vitest 4.0.15
2. TypeScript compilation succeeds
3. No new console warnings/errors during test execution
4. Staging deployment works correctly
