自定义脚手架

一、涉及到的node

1、chalk：控制台输出颜色
const chalk = require('chalk');

console.log(chalk.green(val));

2、ora：控制台loading效果

const ora = require('ora')

const spinner = ora('Project loading...')
spinner.start() // 开始
spinner.fail() // 失败
spinner.succeed() // 成功

3、inquirer：问答对话

const Inquirer = require('inquirer')

const question = [
  {
    type: "input",
    message: "请输入项目名称：",
    name: "projectName",
    default: "lh-pc"
  },
  {
    type: "input",
    message: "请输入作者：",
    name: "author",
    default: 'dev'
  },
  {
    type: "list",
    message: "请选择你的模版：",
    choices: templateKeys,
    name: "templateKey",
    default: "pc-ts",
    validate: (val) => {
      console.log(chalk.green(val));
      if (val) {
        return true;
      } else {
        console.log(chalk.yellow('请选择一个模版'))
        return false
      }
    }
  }
]
// 结果
Inquirer.prompt(question).then((answers) => {
  
})

4、download-git-repo： 克隆下载git仓库

const download = require('download-git-repo')

 download(`direct:${git地址}`, '项目名',{clone:true}, err=>{
    console.log(chalk.red(err))
    if(err) {
        
        console.log(chalk.red(`Project loading failed`))
        return
    }
  })

我的配置--server.js

const chalk = require('chalk');
const ora = require('ora') // loading效果
const Inquirer = require('inquirer')
const download = require('download-git-repo')
const path = require('path')
const template = require('./template.json')
const templateKeys = Object.keys(template)
const question = [
  {
    type: "input",
    message: "请输入项目名称：",
    name: "projectName",
    default: "lh-pc"
  },
  {
    type: "input",
    message: "请输入作者：",
    name: "author",
    default: 'dev'
  },
  {
    type: "list",
    message: "请选择你的模版：",
    choices: templateKeys,
    name: "templateKey",
    default: "pc-ts",
    validate: (val) => {
      console.log(chalk.green(val));
      if (val) {
        return true;
      } else {
        console.log(chalk.yellow('请选择一个模版'))
        return false
      }
    }
  }
]

Inquirer.prompt(question).then((answers) => {
  console.log('answers', chalk.yellow(JSON.stringify(answers)))
  const spinner = ora('Project loading...')
  spinner.start()
  const { projectName,templateKey } = answers
  const tempUrl = template[templateKey]
  download(`direct:${tempUrl}`,projectName,{clone:true}, err=>{
    console.log(chalk.red(err))
    if(err) {
        spinner.fail()
        console.log(chalk.red(`Project loading failed`))
        return
    }
    spinner.succeed()
  })
})
