@jsxtools/rollup-plugin-cem is a rollup plugin for generating a Custom Elements Manifest file from the Rollup module graph.

This plugin is designed to work in conjunction with the @jsxtools/rollup-plugin-tsc plugin.

Usage

import { rollupPluginTsc } from '@jsxtools/rollup-plugin-tsc'
import { rollupPluginCem } from '@jsxtools/rollup-plugin-cem'

export default {
  input: 'src/index.ts',
  output: {
    file: 'dist/bundle.js',
    format: 'es'
  },
  plugins: [
    rollupPluginTsc(),
    rollupPluginCem({
      // optional configuration
      manifestFile: 'dist/custom-elements.json'
    })
  ]
}

Features

• Analyzes TypeScript source files to generate a Custom Elements Manifest file.

• plugins - Additional CEM analyzer plugins.
• include - Glob patterns for files to include.
• exclude - Glob patterns for files to exclude.
• distDir - Distribution directory (default: dist).
• rootDir - Source directory (default: src).
• workDir - Current working directory (default: current process directory).

  fastPlugin,
