acorn-parse-escodegen-generate-esm-broweser

可以在浏览器中运行，不需要 nodejs 环境，压缩后体积为 155KB

使用 acorn和escodegen 来 进行 javascript 源代码 和 抽象语法树的相互转换的ES模块,

把escodegen和estraverse和esutils模块都从commonjs模块改成ES模块,acorn使用自带的ES模块

并且使用rollup 打包,并开启tree-shaking和使用terser代码压缩

获取已压缩模块

ES 模块

从 cdn 获取

https://cdn.jsdelivr.net/gh/masx200/acorn-parse-escodegen-generate-esm-broweser@latest/dist/acorn-parse-escodegen-generate.esm.min.js

<script type="module">
    import {
        parse,
        generate,
    } from "https://cdn.jsdelivr.net/gh/masx200/acorn-parse-escodegen-generate-esm-broweser@latest/dist/acorn-parse-escodegen-generate.esm.min.js";
</script>

安装模块

npm install --save https://github.com/masx200/acorn-parse-escodegen-generate-esm-broweser.git

或者

yarn add https://github.com/masx200/acorn-parse-escodegen-generate-esm-broweser.git

import { parse, generate } from "acorn-parse-escodegen-generate-esm-broweser";

var code = "var b=3";
var ast = parse(code);
var text = generate(ast);
