1.获取命令行：yargs-parser

args[0] 创建的目录名称

  1. const yParser = require('yargs-parser');
  2. // 获取命令行参数，从下标2开始
  3. const args = yParser(process.argv.slice(2));

2.命令行交互：inquirer

  1. const run = async (config) => {
  2.     // node子进程emit
  3.     process.send && process.send({ type: 'prompt' });
  4.     process.emit('message', { type: 'prompt' });
  6.     let { type } = config;
  7.     if (!type) {
  8.         const answers = await inquirer.prompt([
  9.             {
  10.                 name: 'type',
  11.                 message: 'Select the boilerplate type',
  12.                 type: 'list',
  13.                 choices: generators,
  14.             },
  15.         ]);
  16.         type = answers.type;
  17.     }
  18.     try {
  19.         return runGenerator(`./generators/${type}`, config);
  20.     } catch (e) {
  21.         console.error(chalk.red('> Generate failed'), e);
  22.         process.exit(1);
  23.     }
  24. };
