ci: add release quality gates to prevent issue #419 class of misses (#421)

iamdarshshah · web-flow · commit e6d8fda131a9 · 2026-04-10T05:56:29.000-07:00
* ci: add release quality gates to prevent issue #419 class of misses - Add peer dep range assertion to test suite (catches overly-narrow peerDependencies like "^17" that block React 18/19 consumers at install) - Gate npm publish behind React 17/18/19 matrix validation (publish job requires needs:validate to pass before running) - Add test-react-versions workflow: runs tests against React 17, 18, 19 on every push/PR - Add test-build-artifacts workflow: smoke tests CJS require(), ESM export structure, and type declaration presence after each build - Add size-limit (6 kB budget) + bundle size PR comment workflow via andresz1/size-limit-action - Add test-ts-versions workflow: type-checks against TS 4.5/4.7/4.9/5.0/5.4/latest * ci: switch bundle size action to preactjs/compressed-size-action andresz1/size-limit-action checks out the base branch and runs size-limit there, but size-limit isn't in master's package.json yet, causing npx to fail with no JSON output. preactjs/compressed-size-action measures built artifact sizes directly without requiring size-limit on the base branch — same approach used by react-hook-form. * ci: fix React 19 and TypeScript matrix failures React 19: - Swap @testing-library/react to v16 when testing React 19 (v12 calls ReactDOM.unmountComponentAtNode which was removed in React 19) - Also install @testing-library/dom which v16 requires as a peer dep - Mark React 19 as experimental (continue-on-error) — pull-to-refresh touch/mouse event handling has a known compat issue under React 19 that needs a separate fix TypeScript: - Drop 4.5 and 4.7 from the matrix; transitive @types/node uses accessor syntax requiring TS 4.9+, causing parse errors skipLibCheck cannot suppress - Add tsconfig.lib.json (excludes __tests__) — the TS version matrix should check the public API surface, not test infrastructure types - In the workflow, pass --ignoreDeprecations 6.0 for TS >= 6 (moduleResolution node deprecated as node10 in TS 6; ignoreDeprecations is a 5.0+ option so cannot live in tsconfig.json without breaking the TS 4.9 matrix job) * ci: drop Node 18 from CI matrix, bump engines to >=20 Node 18 reached EOL April 2025. @size-limit/preset-small-lib@12 requires Node ^20, causing yarn install to fail on Node 18 in push.yml. * ci: remove React 19 from test matrix until compat fix is ready Pull-to-refresh setState calls are not wrapped in act(), which React 19 treats as an error. Remove React 19 from both test-react-versions.yml and publish.yml to keep CI green. Re-add once the fix lands.
