如何构建一个自己的JavaScript框架或库的脚手架工具？

npm init -y
npm install commander inquirer fs-extra ejs child_process --save

"bin": {
  "create-my-lib": "./bin/index.js"
}

#!/usr/bin/env node
const program = require('commander');
program.version('0.1.0')
  .command('init <project-name>')
  .description('初始化一个新的库项目')
  .action(require('../src/init'));

program.parse(process.argv);

// templates/package.json.ejs
{
  "name": "<%= name %>",
  "version": "0.1.0",
  "main": "dist/index.js",
  "scripts": {
    "build": "rollup -c"
  },
  "keywords": [],
  "author": "<%= author %>"
}

const ejs = require('ejs');
const fs = require('fs-extra');
const path = require('path');

module.exports = async (projectName) => {
  const targetDir = path.join(process.cwd(), projectName);
  await fs.ensureDir(targetDir);

  const templateDir = path.resolve(__dirname, '../templates');
  const files = await fs.readdir(templateDir);

  const answers = await inquirer.prompt([
    { type: 'input', name: 'name', message: 'Project name:', default: projectName },
    { type: 'input', name: 'author', message: 'Author:' }
  ]);

  for (const file of files) {
    const src = path.resolve(templateDir, file);
    const dest = path.resolve(targetDir, file.replace(/\.ejs$/, ''));

    if (path.extname(file) === '.ejs') {
      const content = await ejs.render(await fs.readFile(src, 'utf-8'), answers);
      await fs.writeFile(dest, content);
    } else {
      await fs.copy(src, dest);
    }
  }

  console.log(`✅ 项目 ${projectName} 创建完成！`);
};

const { execSync } = require('child_process');
process.chdir(targetDir);
execSync('npm install', { stdio: 'inherit' });
console.log('? 依赖已安装');

npm link

create-my-lib init my-awesome-lib

npm publish
