搭建一个nodejs脚手架的方法步骤

const chalk = require('chalk')
const symbols = require('log-symbols')
console.log(symbols.success, chalk.green('SUCCESS'))
console.log(symbols.error, chalk.red('FAIL'))

2.2.7 完整文件如下

#!/usr/bin/env node
const chalk = require('chalk')
console.log('Hello, cli!')
console.log(chalk.green('init创建'))
const fs = require('fs')
const program = require('commander')
const download = require('download-git-repo')
const inquirer = require('inquirer')
const ora = require('ora')
const symbols = require('log-symbols')
program
 .version(require('./package').version, '-v, --version')
 .command('init <name>')
 .action((name) => {
   console.log(name)
   inquirer.prompt([
    {
      type: 'input',
      name: 'author',
      message: '请输入你的名字'
    }
   ]).then((answers) => {
    console.log(answers.author)
    const lqProcess = ora('正在创建...')
    lqProcess.start()
    download('github:/Mr-Prune/learn/mongodb-koa',
     name, {clone: true}, (err) => {
     if (err) {
      lqProcess.fail()
      console.log(symbols.error, chalk.red(err))
     } else {
      lqProcess.succeed()
      const fileName = `${name}/package.json`
      const meta = {
       name,
       author: answers.author
      }
      if(fs.existsSync(fileName)){
       const content = fs.readFileSync(fileName).toString();
       const result = handlebars.compile(content)(meta);
       fs.writeFileSync(fileName, result);
     }
     console.log(symbols.success, chalk.green('创建成gong'))
     }
    })
   })
 })
program.parse(process.argv)

总结

通过上面的例子只是能够搭建出一个简单的脚手架工具，其实bash还可以做很多东西，比如 npm 包优雅地处理标准输入、管理并行任务、监听文件、管道流、压缩、ssh、git等，要想了解更多，就要深入了解，这里只是打开一扇门，学海无涯。
