Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

externals plugin for vite

Readme

vite-plugin-externals

English | 简体中文

使用外部库,类似webpack的externals,但现在只支持浏览器环境。

可以不另外配置 rollup 的选项,就可以使用在生产环境。

但是在默认配置下在 commonjs 环境中不生效,例如 ssr

用法

npm i vite-plugin-externals -D

增加配置在 vite.config.js

// vite.config.js
import { viteExternalsPlugin } from 'vite-plugin-externals'

export default {
  plugins: [
    viteExternalsPlugin({
      vue: 'Vue',
      react: 'React',
      'react-dom': 'ReactDOM',
      // 支持值链式取值,会转换成 window['React']['lazy']
      lazy: ['React', 'lazy']
    }),
  ]
}

警告: 如果你在开发环境中,引入了生产环境的库, 可能会使得 HMR 失败。

你也可以使用 disableInServe: true 避免在 serve 模式中转换。

例如:

<!-- 可能会使 HMR 失败 -->
<script src="./vue.global.prod.js"></script>

<!-- 这样不会 -->
<script src="./vue.global.js"></script>

原理

转换js的源代码。

// 选项
viteExternalsPlugin({
  vue: 'Vue',
}),
// 源代码
import Vue from 'vue'
// 转换后
const Vue = window['Vue']

// 源代码
import { reactive, ref as r } from 'vue'
// 转换后
const reactive = window['Vue'].reactive
const r = window['Vue'].ref

// 源代码
import * as vue from 'vue'
// 转换后
const vue = window['Vue']

// 源代码
export { useState as _useState } from 'react'
// 转换后
export const _useState = window['React'].useState

注意: 请使用该插件前,需要把代码转换成js,因为此插件只能解析js代码,例如:

import vue from '@vitejs/plugin-vue'

export default {
  plugins: [
    vue(), // @vitejs/plugin-vue 将会把SFC的代码转换成js代码

    // 所以这插件要放在@vitejs/plugin-vue的下面
    viteExternalsPlugin({
      vue: 'Vue',
    }),
  ]
}

如果出现异常报错,可以查看是否因为插件顺序引起的报错。

配置选项

disableInServe

serve 模式中禁止转换 external 代码。

viteExternalsPlugin({
  vue: 'Vue',
}, { disableInServe: true })

enforce

vite 插件顺序。 解决由于 vite 插件顺序引起的异常。 例如 #21.

详细可以查看 https://vitejs.dev/guide/api-plugin.html#plugin-ordering

filter

此插件会默认过滤 node_modules 下的文件,只转换 js/ts/vue/jsx/tsx 文件。

你可以指定 filter 函数,返回 true 将会进行转换成外部变量。

viteExternalsPlugin({
  vue: 'Vue',
}, {
  filter(code, id, ssr) {
    // 你的代码
    return false
  }
}),

useWindow

默认为 true , 设置 false , window 的作用域将不会加上。

注意: 如果模块名有特殊字符,例如 /,设置useWindow选项 false 将引发错误。

viteExternalsPlugin({
  vue: 'Vue',
}, { useWindow: false }),

// 源代码
import Vue from 'vue'
// 转换后, 不是 `const Vue = window['Vue']`
const Vue = Vue

sourceMapOptions

转换后代码sourceMap的配置项,库是 magic-string
