Parcel: Blazing fast, zero configuration web application bundler.
Parcel
Category:
Advanced
github.com/parcel-bundler/parcel:
Pipeline:
initialization
→ parcel plugin hook
→ HTML entry
→ source.{js,html,css,png}
→ Assets
→ Packager
→ Bundle tree
Parcel 默认入口为 HTML 文件,通过分析在 HTML 里面引入的资源进行加载。
同时:
import xxx from 'xxx'
Parcel 会实时通过 npm 进行包的补充拉取与引入。

只要把插件安装好并保存到 package.json 中。插件需要以 parcel-plugin- 作为前缀被命名。例如 parcel-plugin-foo。任何在 package.json 中被列出的带有此前缀的依赖,都会在初始化的时候被自动加载。
const {Asset} = require('parcel-bundler'); class MyAsset extends Asset { type = 'foo'; // 设置主要输出类型 async parse(code) { // 将代码解析为 AST 树 return ast; } async pretransform() { // 可选。在收集依赖之前转换。 } collectDependencies() { // 分析依赖 this.addDependency('my-dep'); } async transform() { // 可选。在收集依赖之后转换。 } async generate() { // 生成代码。如有需要,可返回多个转换(renditions)。 // 结果会传到合适的 packagers 去生成最终的 bundles return [ { type: 'foo', value: 'my stuff here' // 主输出 }, { type: 'js', value: 'some javascript', // 如若需要,此转换内容可被放到 JS 的 bundle 中 sourceMap } ]; } async postProcess(generated) { // 所有代码生成后的过程 // 可用于组合多种类型资源 } }
