创建模版文件

基础vue模版

module.exports = function () {
  return `
  <template>
      <div></div>
  </template>
  <script>
  export default {
      data() {
          return {}
      }
      methods: {

      }
  }
  </sctipt>
  <style lang="scss" scoped>
  
  </style>
  `;
};

基础react模版

module.exports = function (className) {
  return `
import * as React from 'react';

export class ${className} extends React.Component{
  constructor(props){
      super(props);

      this.state = {}
  }

  componentDidMount(){

  }

  render() {
      return (
          <div></div>
      )
  }
}
  `;
};

文件模版列表

const reactClass = require('./reactClass');
const vueTemplate = require('./vueTemplate');

module.exports = [
    { name: 'reactClass', src: reactClass,fileType:'.jsx' },
    { name: 'vueTemplate', src: vueTemplate,fileType:'.vue'  }
];

读模版配置

// 引入模板文件
const templates = require('../bin/templates/index');

// 命令行选择列表
const prompList = [
    {
        type: 'list',
        name: 'template',
        message: '请选择你想要生成的模板？',
        choices: templates,
        default: templates[0]
    }
];

module.exports = {
  templates,
  prompList
};
