[PR #778](https://github.com/shakacode/shakapacker/pull/778) by [justin808](https://github.com/justin808). Resolves [#707](https://github.com/shakacode/shakapacker/issues/707). + - Enhanced type safety across configFile, buildValidator, and yamlSerializer modules + - Improved error message preservation for webpack/rspack build failures + - Fixed edge cases in YAML serialization (empty arrays, malformed objects) + - More robust constructor name detection for object serialization + - Better handling of Symbol, BigInt, and edge case types - **Default template no longer triggers production warning**. [PR #774](https://github.com/shakacode/shakapacker/pull/774) by [justin808](https://github.com/justin808). Fixes [#703](https://github.com/shakacode/shakapacker/issues/703). - Changed default `useContentHash` to `true` in `shakapacker.yml` template - Eliminates confusing warning about `useContentHash: false` not being allowed in production diff --git a/eslint.config.js b/eslint.config.js index a1133bae1..12dd3397f 100644 --- a/eslint.config.js +++ b/eslint.config.js @@ -23,7 +23,9 @@ module.exports = [ // Temporarily ignore TypeScript files until technical debt is resolved // See ESLINT_TECHNICAL_DEBT.md for tracking // TODO: Remove this once ESLint issues are fixed (tracked in #723) - "package/**/*.ts" + // Exception: configExporter is being fixed in #707 + "package/**/*.ts", + "!package/configExporter/**/*.ts" // Enable linting for configExporter (issue #707) ] }, @@ -189,21 +191,48 @@ module.exports = [ } }, { + // #707: Significant type safety improvements in configExporter module! + // - configFile.ts: ✅ Fully type-safe (0 type errors) + // - buildValidator.ts: ✅ Fully type-safe (0 type errors) + // - yamlSerializer.ts: ✅ Fully type-safe (0 type errors) + // - cli.ts: ⚠️ Partial (dynamic webpack config loading requires some `any`) + // + // Remaining overrides are for: + // 1.
