grunt中调用webpack

项目中一些很老的技术需要运用webpack管理，这时候必须使用grunt+webpack 配合使用 。做个笔记，不限多说直接上代码

grunt结合webpack

下面是 Gruntfile.js

const path = require('path')
const fs = require('fs');
const webpack = require("./webpack.config.js");
const destuglifyls = ['dest/limsStyle/equation.js', 'dest/limsStyle/guidance.js', 'dest/limsStyle/postil.js', 'dest/limsStyle/inject.js', 'dest/limsStyle/designTemp.js'];
const srcbabells = ['limsStyle/postil.js', 'limsStyle/equation.js', 'limsStyle/guidance.js', 'limsStyle/inject.js', 'limsStyle/designTemp.js'];
const srcjshint = ['src/limsStyle/postil.js', 'src/limsStyle/equation.js', 'src/limsStyle/guidance.js', 'src/limsStyle/inject.js', 'src/limsStyle/designTemp.js'];

module.exports = function (grunt) {
  grunt.registerTask('setapi', 'setapi..', function (arg1, arg2) {
    var RouteMapLibPath = './dest/limsStyle/RouteMapLib-1.1.js';
    var editConfigPath = './dest/lib/ueditor1_4_3-utf8-net/config.js';
    var data = fs.readFileSync('./dest/limsStyle/config.json');

    var RouteMapLib = fs.readFileSync(RouteMapLibPath).toString();
    var editConfigContent = fs.readFileSync(editConfigPath).toString();
    data = JSON.parse(data);
    if (typeof arg1 != 'undefined') {
      switch (arg1) {
        case 'dev':
          {
            replaceConfig(data.devconfig)
          };
          break;
        case 'test':
          {
            replaceConfig(data.testconfig)
          };
          break;
        case 'build':
          {
            replaceConfig(data.buildconfig)
          };
          break;
      }
    } else {
      replaceConfig(data.location)
    }
    fs.writeFileSync(RouteMapLibPath, RouteMapLib);
    fs.writeFileSync(editConfigPath, editConfigContent);

    function replaceConfig(d) {
      RouteMapLib = RouteMapLib.replace('{#ajaxUrl}', d.ajaxUrl);
      RouteMapLib = RouteMapLib.replace('{#user_token}', d.user_token);
      RouteMapLib = RouteMapLib.replace('{#ELNEdit}', d.ELNEdit);
      editConfigContent = editConfigContent.replace('{#server}', d.ajaxUrl.replace('API/', ''));
      // console.log(RouteMapLib);
    };

  });
