🚀 Installation

# Using yarn (recommended)
yarn add -D pkg-typescript

# Using npm
npm install --save-dev pkg-typescript

📖 Quick Start

1. Create a package.ts file in your project root:

import { PackageConfig } from 'pkg-typescript'

const config: PackageConfig = {
  name: 'my-awesome-package',
  version: '1.0.0',
  scripts: {
    dev: 'vite dev',
    build: 'vite build',
    pre: {
      build: 'echo "Starting build..."',
    },
    post: {
      build: 'echo "Build complete!"',
    },
  },
  dependencies: {
    react: [18, 0, 0],
    lodash: ['github', 'lodash/lodash'],
  },
  devDependencies: {
    typescript: [5, 0, 0],
    vite: [4, 0, 0],
  },
}

export default config

2. Generate your package.json:

npx pkg-ts build

🛠️ CLI Commands

pkg-ts build

Generate package.json from your TypeScript configuration:

# Build single package
pkg-ts build

# Build specific package file
pkg-ts build --config my-package.ts

# Build all packages in directory
pkg-ts build --all

pkg-ts sync

Sync version between package.json and your TypeScript config:

# Sync version from package.json to package.ts
pkg-ts sync

# Sync specific config file
pkg-ts sync --config my-package.ts

pkg-ts add-plugin

Add a plugin to your package configuration:

pkg-ts add-plugin my-plugin

pkg-ts update

Update package configurations:

pkg-ts update

📋 Configuration

PackageConfig Interface

The PackageConfig interface provides full type safety for your package configuration:

export type PackageConfig<T = any> = {
  name: string
  version: string
  license?: string
  type?: 'plugin'
  plugins?: string[]
  private?: boolean
  scripts: {
    dev?: string
    build?: string
    start?: string
    pre?: PreScripts
    post?: PostScripts
    [key: string]: string | undefined | PreScripts | PostScripts
  }
  dependencies?: Record<string, Dependency>
  devDependencies?: Record<string, Dependency>
  config?: T
}

Dependency Types

Define dependencies using semantic versioning arrays or GitHub sources:

// Semantic version [major, minor, patch]
dependencies: {
  'react': [18, 2, 0],
  'lodash': [4, 17, 21]
}

// GitHub source
dependencies: {
  'my-package': ['github', 'username/repo']
}

// Latest version
dependencies: {
  'some-package': 1
}

Pre/Post Scripts

Define scripts that run before or after main scripts:

scripts: {
  build: 'webpack build',
  pre: {
    build: 'rm -rf dist',
    version: 'npm run test'
  },
  post: {
    build: 'npm run deploy',
    version: 'git push --tags'
  }
}

🧩 Plugin System

Create reusable plugins to extend functionality:

// my-plugin.ts
import { PluginFunction } from 'pkg-typescript'

interface MyPluginConfig {
  feature: boolean
}

const myPlugin: PluginFunction<MyPluginConfig> = (config) => {
  return {
    scripts: {
      'my-command': 'echo "Plugin command"',
    },
    dependencies: {
      'plugin-dep': [1, 0, 0],
    },
  }
}

export default myPlugin

Use plugins in your package configuration:

import myPlugin from './my-plugin'

const config: PackageConfig = {
  name: 'my-package',
  version: '1.0.0',
  plugins: ['my-plugin'],
  // ... rest of config
}
