chore: ESLint v10, GitHub Actions updates, stylelint config migration, and website fixes by Copilot · Pull Request #1828 · htmlhint/HTMLHint

Copilot · 2026-03-20T08:19:07Z

Batch of maintenance updates: ESLint v9→v10, GitHub Actions version bumps, stylelint config format migration, and Astro SpeculationRules correction.

ESLint v10

eslint ^9.x → ^10.1.0 (latest); added explicit @eslint/js@^10.0.0 dep (required in v10)
@typescript-eslint packages 8.44.0 → 8.57.1
Fixed two no-useless-assignment errors surfaced by v10:
- src/cli/htmlhint.ts: inlined ruleset as const inside the try block
- src/core/reporter.ts: moved evidenceLen declaration inside the for loop as const

GitHub Actions

Deleted accessibility-alt-text-bot.yml (no longer needed)
Version bumps across all workflows:

Action	Before	After
`actions/setup-node`	v6.2.0	v6.3.0
`actions/upload-artifact`	v6.0.0	v7.0.0
`github/codeql-action`	v4.32.4	v4.33.0
`streetsidesoftware/cspell-action`	v8.2.0	v8.3.0
`styfle/cancel-workflow-action`	0.13.0	0.13.1

Website

Migrated website/.stylelintrc.json → website/stylelint.config.mjs (ESM format)
Astro speculationrules: "prerender" → "prefetch"

website/stylelint.config.mjs

+export default {
+  extends: ['stylelint-config-recommended'],
+  rules: {},
+}


website/package.json does not declare "type": "module", so Node will treat stylelint.config.js as CommonJS. Using export default in a CommonJS .js file will throw a syntax error when Stylelint loads the config. Consider either switching this file to CommonJS (module.exports = { ... }) or renaming it to stylelint.config.mjs (or adding type: module) so the ESM syntax is valid.

Suggested change

export default {

extends: ['stylelint-config-recommended'],

rules: {},

}

module.exports = {

extends: ['stylelint-config-recommended'],

rules: {},

};

@copilot change to stylelint.config.mjs

Already renamed to stylelint.config.mjs in 429b5b8.

This change doesn't actually stop CodeQL from running on draft PRs: the opened/synchronize/reopened events still fire for drafts, and removing ready_for_review means CodeQL won't automatically run when a draft is marked ready. To skip drafts reliably, add a job-level if: github.event.pull_request.draft == false (for pull_request events) and include ready_for_review in the trigger types (or omit types entirely).
