手动编译ts的经过

动机

以前写ts或者es6，都是用在脚手架搭建的项目中，比如vue和react，当时当我识图写一个ts的demo的，我还要创建一个完整的vue或者react项目？明显不合适，那就要研究一下如何手动搭建一套编译调试环境

源代码
src/index.ts

/*因为编译后的代码包含es6新增api，比如下边的includes，有浏览器可能不支持，故而需要引入垫片
这里可以选择core-js，也可以ts-polyfill，目的都是一样的*/
import 'core-js'; 

//具体目标
class Utils {
    protected cname:string = 'Utils';
    public test(): void{
        [1,2,3].includes(2)
    }          
}
(window as any).subject = new Utils(); //方便页面使用

方案1：tsc编译+手动做垫片+webpack处理模块

使用tsc编译
tsconfig.json配置如下

{
  "compilerOptions": {
    "target": "es5", /* 编译的目标是什么版本的 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', 'ES2018', 'ES2019' or 'ESNEXT'. */
    "module": "commonjs",/* 编译后模块化类型 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
    "lib": [ //编译过程中需要引入的库文件的列表。
      "es5",
      "es2016.array.include",
      "dom" //因为ts内用到了window
    ], 
    "strict": true,
    "esModuleInterop": true
  }
}

运行tsc命令后，编译后的代码src/index.js

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
// import 'core-js';
require("ts-polyfill/lib/es2016-array-include");
//具体目标
var Utils = /** @class */ (function () {
    function Utils() {
        this.cname = 'Utils';
    }
    Utils.prototype.test = function () {
        [1, 2, 3].includes(2);
    };
    return Utils;
}());
window.subject = new Utils(); //方便页面使用

可以从代码中看到，tsc只是将ts代码编译js代码。有两个问题仍然需要我们处理，
他不管浏览器对编译后的js代码的兼容如何，所以我们需要手动做垫片，所以我们在入口文件src/index.ts处已经引入了coreJs做了垫片
然后他不处理模块化代码部分，比如import，export。目前node直接使用没问题，但是如果放在浏览器，2019年年底浏览器均不支持，所以需要webpack进行模块化处理。

我们将项目中安装webpack，并添加配置文件
npm install --save-dev webpack webpack-cli

const path = require('path');

module.exports = {
  mode: 'development',
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'main.js'
  }
};

然后通过webpack命令webpack --mode development --progress来打包处理模块化,编译成功后的代码会很长，这里就不直接展开了。

将编译后的文件直接通过script的方式引入页面，就可以使用了

<body>
    <script src="./dist/main.js"></script>
</body>

缺点：垫片要手动处理，不智能。用到了两个工具

方案二：ts编译+babel接手垫片+webpack模块化

我们源代码需要改动一下，删除头部引入coreJs，我们不需要手动做垫片

//具体目标
class Utils {
    protected cname:string = 'Utils';
    public test(): void{
        [1,2,3].includes(2)
    }          
}
(window as any).subject = new Utils(); //方便页面使用

仍旧是ts编译，可以看到编译后src/index.js的代码，明显也少了引入垫片corejs这行代码

"use strict";
//具体目标
var Utils = /** @class */ (function () {
    function Utils() {
        this.cname = 'Utils';
    }
    Utils.prototype.test = function () {
        [1, 2, 3].includes(2);
    };
    return Utils;
}());
window.subject = new Utils(); //方便页面使用

安装babel，让babel处理垫片。创建babel配置文件babel.config.js
装babel的时候让我惊讶的是，不用安装@babel/polyfill也能(babel)编译和(webpack)模块打包成功，分析了下原因:
1、编译阶段是不需要垫片的，因为此时编译后的文件只是多出来了垫片的引用，是否找得到编译器它不考虑
2、垫片的使用时发生在用webpack打包阶段，因为他要处理垫片生成的import，import的内容就是垫片库@babel/polyfill里的文件，如果你没有安装此包webpack处理的时候找不到会报错
3、至于我为啥后边webpack成功了，是因为我刚才误多装了core-js包，而这个包恰恰就是我需要的垫片包，
    因为我的babel是7.4以上，@babel/polyfill已经被废弃了被分解成了core-js、regenerator-runtime两个包，刚好歪打正着。所以我们可以提前安装上这两个包，不然webpack打包阶段会报错

const presets = [
    [
      "@babel/env",
      {
        useBuiltIns: "usage" //自动按需引入对应的垫片
      },
    ],
  ];
module.exports = { presets };

执行babel打包命令npx babel src/index.js --out-dir src，打包后的src/index.js有看到babel已经帮我们处理好了垫片环境

"use strict"; //具体目标

require("core-js/modules/es7.array.includes");

require("core-js/modules/es6.string.includes");

var Utils =
/** @class */
function () {
  function Utils() {
    this.cname = 'Utils';
  }

  Utils.prototype.test = function () {
    [1, 2, 3].includes(2);
  };

  return Utils;
}();

window.subject = new Utils(); //方便页面使用

然后我们再用webpack处理模块化webpack --mode development --progress。然后他妈的就报错了

ERROR in ./src/index.js
Module not found: Error: Can't resolve 'core-js/modules/es6.string.includes' in '/Users/dsh/Documents/demo/tsceg/src'
@ ./src/index.js 5:0-46

ERROR in ./src/index.js
Module not found: Error: Can't resolve 'core-js/modules/es7.array.includes' in '/Users/dsh/Documents/demo/tsceg/src'
@ ./src/index.js 3:0-45

我仔细的瞅了瞅node-module下边的core-js包，发现包里的moduels下就没有es6.string.includes和es7.array.includes这两个文件。我跑到github下找到这货的项目，看了看v3确实没有，但是v2还有，那看来就是第一种方案的时候，手动装垫片的时候，coreJs的版本默认给我装到v3。简言之，版本装错了，重新改成v2后就好了，一下是打包后的文件，就不展开了

 缺点：虽然编译成了老版本的js和做了垫片，但是却多用了一个工具babel，现在是一工3个工具

方案三：只用webpack(ts-loader + babel-loader)
webpack的优秀之处在于，他能以loader和plugin的方式将其他工具整个到自身内。那么我们分别用ts-loader和babel-loader来仅用webpack去处理ts。避免了使用过多的工具的问题。
新建一个项目，
初始化node配置文件自动生成packge.json。
安装webpack，并新增配置文件。
新增入口文件src/index.ts
测试页面引入编译后的dist/main.js文件，别的内容没有
目录解构如下：


1、安装ts-loader，主要分4部分
npm install ts-loader typescript --save-dev
安装ts-loader
安装typescript
新增tsconfig.json,配置文件内容如上（当然也可以像下边babel配置文件的方式一样，只是懒得重复演示）
配置webpack对ts的loader规则，具体文件下边一起放出

2、安装babel-loader
其实这个时候，执行webpack就可以将ts编译为js了，但是为了兼容老的浏览器，我们要用babel来做垫片
安装babel核心库和babel-loader以及babel欲设
npm install -D babel-loader @babel/core @babel/preset-env

另外就是垫片包了，babel7.4以上，@babel/polylill已经被启用了，代替他的是core-js、regenerator-runtime这两个包，记得安装
npm install -D core-js regenerator-runtime

然后把babel的配置转移到webpack的配置文件里就行，无需额外的配置文件

const path = require('path');

module.exports = {
  mode: 'development',
  entry: ['./src/index.ts'],
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'main.js'
  },
  module: {
    rules: [
      { test: /.ts$/,use: [
        {
          loader: 'babel-loader',
          options: {
                presets: [
                    [
                        '@babel/preset-env',
                        {
                        "useBuiltIns": "usage",
                        "corejs": 3,
                        "targets": {"browsers":["> 1%"]},
                        }
                    ]
                ],
                // 我是真搞不懂这厮，编译现在不用它也不会报错，同学们视情况而定吧，报错用
                // 我认为可能是ts-loader已经给处理了类的实例属性，所以交付给babel-loader的时候，就不会有解析不过的问题了
                // plugins:[
                //     ["@babel/plugin-proposal-class-properties", { "loose": true }]
                // ]  
            }
        },
        {loader: 'ts-loader'}
    ]}
    ]
  }
};

这里有详细的关于匹配多个loader的用法

3、然后直接用webpack进行编译就行了
npx webpack --config webpack.config.js

优点在于一口气配置完后，只需要一个命令行就编译打包完。

对了提一下配置，如果用了ts-loader和babel-loader，
在tsconfig的配置中，尽量不要处理模块化，编译的语法也不要设置成比较低的es版本。因为后续babel会做。这是哪个老外告诉我的

 esnext是指es最新的标准，ts是es基础上加了类型，target esnext基本就等于是ts只做类型检查，然后去掉类型标注得到es代码

缺点：虽然只用了一个工具，但是却用了两个loader，ts-loader和babel-loader，需要两个工具的安装 引入和配置

方案四：只用webpack(里边只用babel-loader)
现在新版的babel可以直接处理ts文件了，那么相应的的babel-loader也能处理。所以我们都可以省去一步，或者省掉一个loader，只用增加配置babel-loader就搞定
要想让babel-loader支持ts解析，那么需要安装一个插件@babel/preset-typescript，然后在修改配置文件webpack.config.js如下

const path = require('path');

module.exports = {
  mode: 'development',
  entry: ['./src/index.ts'],
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'main.js'
  },
  module: {
    rules: [
      { test: /.js$|.ts$/, loader: "babel-loader",exclude: /node_modules/,
        options: {
          presets: [
            [
              '@babel/preset-env',
              {
                "useBuiltIns": "usage",
                "corejs": 3,
                "targets": {"browsers":["> 1%"]},
              }
            ],
            ["@babel/preset-typescript"]
          ],
          plugins:[
            ["@babel/plugin-proposal-class-properties", { "loose": true }]
          ]
        }
      }
    ]
  }
};

因为我的代码里，有类实例属性定义，目前es6还不支持在类里定义属性，只能定义方法（妈的，刚才试了下，chrome78居然支持了），但估计支持没几年吧
而且@babel/preset-typescript也尚未支持对此的处理（如果用了ts-loader的话，它就给处理了，所以这也是方案三 为啥没装这个插件也可以编译的原因了）
所以编译的时候需要安装一个额外的插件去处理此类语法，@babel/plugin-proposal-class-properties，并加入到如上的配置文件的plugins里。
我好奇，如果是js我定义了类的实例属性，会不会也需要这个插件，果然需要。
所以这个就是用来专门处理js或ts等类的实例属性编译机制的，所以单独拉出来做了个插件。
如果在preset-env和preset-typescript集合里内置了这个插件就好了，我觉得很常用啊，不然还得自己单独去加到plugins里

完事之后在webpack编译。就大工告成啦

通过配置文件分析可知，webpack已经不需要ts-loader了，而作为ts-loader的依赖包typescript也自然不需要了，作为ts的配置文件tsconfig.json也可以删除了。这样就省去了大量的ts第三方包和配置

缺点：需要较高版本的babel，但是这个问题会随着时间迎刃而解

babelCli直接编译ts
刚才有提到，babel7可以直接处理ts了，下边就讲一下单独使用babel工具的话，使用步骤？
新建一个空项目，创建src/index.ts后，除了安装如上必须的babel工具之外，还要做如下处理
a：首先要安装一个预设：npm install @babel/preset-typescript -D
b：如果你的类里边就像我的代码一样有类的实例属性，那么还要安装一个支持该特性的插件：
　　npm install @babel/plugin-proposal-class-properties -D
c：然后创建babel的配置文件babel.config.js

然后运行npx babel src/index.ts --out-dir dist即可

所以最后的结论就是，用一个工具webpack，加一个处理器babel-loader就完全可以搞定ts啦
