Changelog

All notable changes to this project will be documented in this file.

[0.1.25] - 2026-07-14

Fixed

  • CJS build bundled npm dependencies inline - The CJS build was missing packages: "external", so it bundled every bare-specifier import — including peerDependencies — into the .cjs output, while the ESM build correctly externalized them. Consumers of the CJS entry got a second copy of each peer package, and builds failed with Could not resolve in CI when a peer's dist/ wasn't present. Fixes #8.

[0.1.24] - 2026-02-21

Fixed

  • Bin exports not rewritten for dist - fixExportsForDist now handles ./dist/bin/ → ./bin/ paths, matching the existing ./dist/src/ → ./src/ behavior. Previously, packages with bin exports would publish with broken import paths in the exports map.

[0.1.23] - 2026-02-20

Added

  • Cross-platform test runner - Test runner with Bun, Node, and browser support (#3)

[0.1.22] - 2025-12-22

Fixed

  • Bin imports from src polluting source tree - Fixed .d.ts files being emitted to source directories when bin entries import from ../src/. This caused lint failures and polluted the src/ folder. Fixes #2.

[0.1.21] - 2025-12-22

Fixed

  • Internal module .d.ts generation - Fixed issue where .d.ts files were not generated for internal modules (e.g., src/impl/utils.ts), causing broken import paths in published packages. TypeScript now follows imports to generate declarations for all modules, not just entry points.
  • Module augmentation in .d.ts - Fixed declare module blocks (module augmentation) not appearing in published type definitions. This resolves #1.
  • Symlink path consistency - Fixed path mismatches on macOS where /tmp symlinks to /private/tmp, which could cause .d.ts files to be emitted to wrong locations.

Changed

  • Chunk files location - ESM code splitting chunks are now placed in dist/src/_chunks/ instead of the dist root, keeping the package structure cleaner.

[0.1.20] - 2025-12-08

Fixed

  • Ambient .d.ts export validation - Fixed validation error when using --save with ambient .d.ts files. The build now correctly handles both ./src/ and ./dist/src/ paths for ambient declarations in exports.

[0.1.19] - 2025-12-08

Added

  • Ambient .d.ts exports - Ambient TypeScript declaration files (*.d.ts) in src/ are now automatically added to the exports map, making them discoverable and importable by consumers.
  • Triple-slash references for ambient types - Generated .d.ts files now include triple-slash reference directives to ambient .d.ts files, ensuring TypeScript can find ambient type declarations.

Fixed

  • Hard fail on invalid workspace package.json - Invalid JSON in workspace dependencies now causes build to fail immediately with clear error instead of silently continuing with a warning.

[0.1.18] - 2025-12-02

Changed

  • BREAKING: Scripts not copied to dist - Scripts field is no longer copied to dist/package.json as they don't work correctly in the dist context (can't reference other scripts that were filtered out). This fixes the issue where prepublishOnly guards would block libuild publish. Users who need install scripts (postinstall, etc.) can manually add them to dist/package.json if needed.
  • prepublishOnly guards for root - Root package.json gets prepublishOnly guard (via --save) to prevent accidental publishing from root directory.
  • Copy private field - The private field is now properly copied from root to dist/, enabling actual private packages to work with libuild while npm prevents their publication.

[0.1.17] - 2025-11-25

Added

  • Ambient .d.ts file copying - Hand-written ambient TypeScript declaration files (e.g., global.d.ts with declare module statements) are now automatically copied from src/ to dist/src/ during build. These files are automatically discovered by TypeScript when the package is consumed, providing global type declarations for module augmentation.

Fixed

  • Non-deterministic export field ordering - Fixed issue where package.json exports fields (types/import/require) would reorder non-deterministically across rebuilds with --save flag, causing unnecessary git diffs. All builds now consistently use types-first ordering.

[0.1.16] - 2025-01-14

Added

  • Code splitting for dynamic imports - ESM builds now use ESBuild's splitting: true to create separate chunk files for dynamically imported modules, enabling lazy loading and reducing initial bundle size
  • Smart entry point detection - Packages with only "." or bin exports build only index.ts as entry point, allowing subdirectory files to be chunked when dynamically imported
  • Code splitting warning - Warns when dual-format builds have chunks, informing users that CommonJS builds cannot benefit from code splitting (CJS bundles dynamic imports inline)

Fixed

  • Export validation - Invalid export paths that don't point to src/ files are now properly validated and rejected with clear error messages

[0.1.15] - 2025-01-14

Fixed

  • Support bin-only packages - Packages with only bin/ executables and no src/ library code no longer crash. Main/module/types fields and "." export are now correctly omitted for bin-only packages, while bin exports are properly generated.

[0.1.14] - 2025-01-14

Fixed

  • Eliminate stderr noise from dual-purpose shebang - Changed from //bin/true to standard polyglot pattern ':' //; to prevent shell from attempting to execute non-existent path, eliminating "No such file or directory" errors while maintaining dual runtime detection

[0.1.13] - 2025-01-14

Fixed

  • Dual runtime shebang for src/ executables - src/ files referenced in package.json bin field now correctly receive dual runtime shebang support (previously only bin/ directory files were processed)
  • All executable files now have consistent dual runtime behavior regardless of directory location

[0.1.12] - 2025-01-14

Added

  • Dual runtime support for bin entries with intelligent bun/node detection based on package manager context
  • Top-level await (TLA) support with graceful CJS fallback - automatically disables CJS generation when TLA is detected
  • bin/ directory support for executable entrypoints alongside src/ entries
  • Respect engines.bun field for runtime preferences in dual runtime detection
  • Automatic shebang replacement with shell script wrapper for maximum compatibility

Changed

  • Single-batch ESM build - combined src/ and bin/ builds for better performance
  • Smart externalization - entry points are externalized, nested files are bundled to prevent code duplication
  • TypeScript declarations now conditional on tsc availability (no failures in environments without TypeScript)

Fixed

  • Fix TypeScript declaration generation for bin entries
  • Fix CLI argument parsing for directory paths with npm flags
  • Fix externalization to only apply to entry points, not nested utility files

[0.1.11] - 2025-11-02

Fixed

  • CRITICAL: Workspace dependencies (workspace:*) are now properly resolved to actual version numbers during build
  • Validation warnings for valid libuild output paths (dist/src/ files that libuild creates)

[0.1.10] - 2025-10-29

Added

  • Automatic cleanup of invalid bin/exports paths when using --save flag
  • Clear messaging that libuild is zero-config with NO libuild.config.js file

Fixed

  • --save now validates and removes bin/exports entries pointing to non-existent files
  • Package.json fields are regenerated based on actual built files during --save
  • Validation logic is now context-aware of --save flag to prevent warnings about configuration that libuild itself creates
  • CLI argument parsing to prevent npm flags from being incorrectly treated as directory arguments

[0.1.9] - 2025-10-29

Fixed

  • Preserve import attributes (with { type: "json" }) in externalized JSON imports to prevent Node.js runtime errors
  • Upgrade Node.js target to 18+ and engines requirement to >=18.20.0 for import attributes support

[0.1.8] - 2025-10-29

Added

  • Directory argument support for CLI commands - can now run libuild build /path/to/project

Fixed

  • Eliminated unnecessary CommonJS helpers (__commonJS, __require) in ESM output by externalizing JSON imports
  • Simplified externalization strategy using packages: "external" for cleaner Node.js CLI builds

[0.1.7] - 2025-10-28

Added

  • Auto-ignore patterns for common test file conventions
    • Automatically ignores *.test.* files (Jest/Vitest standard)
    • Automatically ignores *.spec.* files (Jasmine/Angular standard)
    • Automatically ignores __tests__/ directories (Facebook/React standard)
    • Automatically ignores test/ directories (simple test directory standard)
