Vite Integration For Go
A simple module that lets you serve your Vue 3 project from a Go-based web server. You build your project, tell Go where to find the dist/ directory, and the module figures out how to load the generated Vue application into a web page. Right now, the only configuration is the manifest.json from your Vue build.
Installation
go get github.com/torenware/vite-go
Getting It Into Your Go Project
You need to expose the dist/ directory so Go can find your generated assets for the Vue project, and the manifest.json file that describes it. You may need to change your vite.config.ts file to make sure the manifest file is generated, and to put the dist directory where Go needs it to be. Here's what I'm using:
/**
* @type {import('vite').UserConfig}
*/
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
export default defineConfig({
plugins: [vue()],
build: {
outDir: 'cmd/web/dist',
sourcemap: true,
manifest: true,
rollupOptions: {
input: {
main: 'src/main.ts',
},
},
},
});
Here's some pseudo-ish sample code that uses the go 1.16+ embedding feature:
package main
import (
"embed"
"html/template"
"net/http"
vueglue "github.com/torenware/vite-go"
)
//go:embed "dist"
var dist embed.FS
var vueGlue *vueglue.VueGlue
func main() {
// Parse the manifest and get a struct that describes
// where the assets are.
glue, err := vueglue.NewVueGlue(&dist, "dist")
if err != nil {
//bail!
}
vueGlue = glue
// and set up your routes and start your server....
}
func MyHandler(w http.ResponseWriter, r *http.Request) {
// Now you can pass the glue object to an HTML template
ts, err := template.ParseFiles("path/to/your-template.tmpl")
if err != nil {
// better handle this...
}
ts.Execute(respWriter, vueGlue)
}
Your template gets the needed tags and links something like this:
<!doctype html>
<html lang='en'>
{{ $vue := . }}
<head>
<meta charset='utf-8'>
<title>Home - Vue Loader Test</title>
{{ if $vue }}
{{ $vue.RenderTags }}
{{ end }}
</head>
<body>
<div id="app"></div>
</body>
</html>
Caveats
This code is a proof of concept, and while it works in my sample application, it may not work for you :-) I've posted the code so people can see it, and kick the tires on it. It's no where near production ready, and, well, it may bite.

Types ¶
type VueGlue ¶
type VueGlue struct {
// Entry point for JS
MainModule string
// JS Dependencies / Vendor libs
Imports []string
// Bundled CSS
CSSModule []string
// I use a 'data-entryp' attribute to find what
// components to load. Lookup is in the entry point JS.
// This makes the info easily available in templates.
MountPoint string
// An embed that points to the Vue/Vite dist
// directory.
DistFS fs.ReadFileFS
}
type VueGlue summarizes a manifest file, and points to the assets.
func NewVueGlue ¶
func NewVueGlue(dist fs.ReadFileFS, pathToDist string) (*VueGlue, error)
NewVueGlue finds the manifest in the supplied file system and returns a glue object.
func ParseManifest ¶
ParseManifest imports and parses a manifest returning a glue object.
