This plugin lets you import Vue single-file components when bundling with esbuild. This plugin works with Vue 2.
Multiple Vue imports are built in parallel using Node.js' worker_threads via Piscina.
yarn add esbuild-vue
In order to use esbuild plugins, you must use esbuild's JavaScript API, instead of the command line.
Let's assume you have a Component.vue, and a main.js that uses it somehow:
# Component.vue
<template>
<h1>Hello, World!</h1>
</template>
# main.js
import Component from './Component.vue';
import Vue from 'vue';
new Vue({
el: '#app',
render: h => h(Component),
});
First, install the plugin, esbuild and Vue:
yarn add esbuild-vue esbuild vue
Next, create a build script build.js:
const vuePlugin = require('esbuild-vue');
require('esbuild').build({
entryPoints: ['main.js'],
bundle: true,
outfile: 'out.js',
plugins: [vuePlugin()],
define: {
"process.env.NODE_ENV": JSON.stringify("development"),
},
});
Then run it:
node build.js
Now, loading index.html should display your component in its full glory.
<!-- index.html -->
<!doctype html>
<div id="app"></div>
<script src="out.js"></script>
An object containing configuration options may be passed into the plugin constructor vuePlugin. For example:
vuePlugin({
extractCss: true,
workers: false,
onReadFile: path => {
console.error("The following dependency was used:", path);
}
})
The following options are available:
extractCss: Output a separate file for inline<style>blocks in single-file components.workers: The maximum amount of worker threads to use for compilation. By default this is 4 or the amount of CPUs available, whichever is least. (During my testing, larger amounts of threads don't provide a performance improvement.) Usefalseto disable multithreading.onReadFile: Will be called with the (non-normalized) paths of every file read during the compilation process. For example, external files included using@importdeclarations in<style>blocks.postcssPlugins: PostCSS plugins which will be used when compiling<style>blocks in components.isAsync: By default, components are compiled using the synchronous (non-async) compiler. If you use async PostCSS plugins, you need to specifytruehere.assembleOptions: Allows to provide customnormalizer,styleInjectorandstyleInjectorSSRimplementations (upstream docs).
