v0.2.1-beta.0

Release Notes - v0.2.1-beta.0

🚀 New Features

Tree Shaking Support (--preserve-modules)

New CLI flag that enables Rollup's preserveModules mode, generating individual files instead of a single monolithic bundle.

package-build -m
package-build --preserve-modules

Benefits:

• Enables effective tree-shaking for consumers
• Reduces bundle size significantly for libraries with many exports (e.g., icon libraries)
• Preserves source directory structure in output

Output structure:

dist/          # CJS modules
es2015/        # ESM modules

📦 Recommended Configuration

For tree-shakable libraries, add to your package.json:

{
  "sideEffects": false,
  "exports": {
    ".": {
      "import": "./es2015/index.js",
      "require": "./dist/index.js"
    }
  }
}

v0.1.2-beta.1

0.1.2-beta.1

0.1.2-beta.0

Changed

• Use typescript 5.

0.1.1

Fixed

• Rollup regression.

0.1.0

Added

• Allow defining typescript project with -p parameter to define a different tsconfig.ts file. p.eg: package-build -p tsconfig.build.json. This is useful to have a tsconfig.json in the root to allow IDE and library implementation to get a project file including files even if they won't be included in the NPM package (.spec, .test, .stories). Otherwise, a project including these files will transform every file defined, even those not desired in the final bundle, not only forcing to exclude them explicitly but increasing compilation times and errors. By default tsconfig.json will be used as it usually does.
