multi-vite demo setup

Vite 2 supports a very nice multi-page setup. The given "multi-page" feature shares one main vite dev server for multiple nested pages, which may now use different src, components, etc.

Similar, a "multi-vite" setup should be able to serve multiple independent vite (or webpack, nuxt, [vite|vue]press) projects in parallel. A developer should even be able to add a new vite+vue3 setup to another existing legacy webpack+vue2 setup within the same webhost. Such a setup requires running a proxy (i.e.: Nginx) in front of all projects and setting the base according to your proxies location paths.

Prerequisites

  • tmuxinator to start the preconfigured tmux sessions.
  • local Docker daemon up and running for demonstration purpose.
  • ports 80 and 443 free to bind by Nginx.

Usage

Yes, we still use Makefiles.

  • make install: installs node_modules and configures docker-compose for Nginx
  • make start: start the whole site in dev mode
  • make stop: stop the whole site

After start, you should be able to point your browser to both

And edit components independently with superfast hmr.

How it's working

For Demo, we set up a directory tree like this one:

├── Makefile
├── package.json
├── repos
│   ├── admin       // 1st repository serving an admin ui (as PWA for example)
│   └── profile     // 2nd repository serving a profile page (as SPA for example)
├── services
│   └── nginx       // nginx config consumed by docker container
└── yarn.lock

Configure all vite instances to serve a baseUrl from their directory.

// ./repos/admin/vite.config.js
import vue from '@vitejs/plugin-vue'

export default {
  base: '/admin/',
  plugins: [vue()],
  server: {
    port: 8082 // <-- port dedicated to admin
  }
}
// ./repos/profile/vite.config.js
import vue from '@vitejs/plugin-vue'

export default {
  base: '/profile/',
  plugins: [vue()],
  server: {
    port: 8081 // <-- port dedicated to profile
  }
}

And connect those instances under the same domain with an Nginx proxy config like so:

  location /admin/ {
    proxy_pass http://host.docker.internal:8082;
  }

  location /profile/ {
    proxy_pass http://host.docker.internal:8081; 
  }

Build

With the base option in place, there is no particular dev setup needed. Each run of:

$ yarn build

will build your project with a base path as prefix right into ./dist. So, for example, the default index.html of admin repository will render like:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <link rel="icon" href="/admin/favicon.ico" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Vite App</title>
  <script type="module" crossorigin src="/admin/assets/index.068891ee.js"></script>
  <link rel="modulepreload" href="/admin/assets/vendor.cee31988.js">
  <link rel="stylesheet" href="/admin/assets/index.b77793a3.css">
</head>
<body>
  <div id="app"></div>
</body>
</html>

To finally serve such a PWA on a production environment, Nginx will get configured with a location like:

location /admin/ {
  alias /path/to/your/admin/dist;
  try_files $uri $uri/ /admin/index.html;
}
