Lucky Vite

A Crystal shard to seamlessly integrate Vite with Lucky Framework.

This shard follows Vite's instructions on how to use Vite with a backend framework

Installation

  1. Add the dependency to your shard.yml:
dependencies:
  lucky_vite:
    github: wout/lucky_vite

  1. Run shards install

  2. Run yarn add -D vite vite-plugin-lucky to install Vite and the plugin for Lucky

Note: Look at vite-plugin-lucky for more info about the plugin.

Setup

There are a few things to set up and change to finalize the installation.

1. Generate files

Run bin/lucky_vite init to create the following files:

Note: The initializer accepts a name option for the entry script: bin/lucky_vite init --name=app.

2. Load the Vite manifest

Replace the Lucky::AssetHelpers.load_manifest line in src/app.cr with:

-Lucky::AssetHelpers.load_manifest
+LuckyVite::AssetHelpers.load_manifest

Note: The load_manifest macro optionally takes a path to the lucky_vite.json config.

3. Register the Vite processes

Update the Procfile.dev by removing the assets process and adding the two following ones:

system_check: script/system_check && sleep 100000
web: lucky watch --reload-browser
-assets: yarn watch
+vite_server: yarn vite
+vite_watcher: yarn watch

4. Register the Vite runners

Change the scripts section in package.json to use vite instead of laravel mix:

{
  // ...
  "scripts": {
-    "heroku-postbuild": "yarn prod",
-    "dev": "yarn run mix",
-    "watch": "yarn run mix watch",
-    "prod": "yarn run mix --production",
+    "heroku-postbuild": "yarn build",
+    "build": "yarn run vite build",
+    "watch": "yarn run vite build --watch"
  },
  // ...
}

Further steps

Usage

Start with including the shard in your app first:

# in src/shards.cr
require "lucky_vite"

Tags

This shard provides three levels of control over the individual Vite tags.

Hands-off

The vite_entry_tags macro method serves all your Vite needs, but it gives you the least amount of control over the individual tags that are generated:

# src/components/shared/layout_head.cr
vite_entry_tags "main.js"

It does a bunch of things. In development, it loads @vite/client and the given entry script. Vite will dynamically load any stylesheets imported in the entry script.

In production, it will load the static versions from the manifest and create individual tags for all of them, including stylesheets. With this macro, the whole frontend is served.

It also accepts any attributes you'd want on all the generated tags:

vite_entry_tags "main.js", data_turbo_track: "reload"

One downside is that the attributes will be applied to all generated tags, which you may not want in some cases.

A bit of control

If you need different attribtues on style tags than on script tags, you can use the following three methods:

vite_client_tag
vite_js_link "main.js"
vite_css_link "main.css"

Together they do the exact same thing as vite_entry_tags.

Note: vite_css_link won't output anything in development as stylesheets are dynamically loaded by Vite.

Full control

If you need even more control over the generated tags, you can use the asset macro in combination with Lucky's js_link and css_link methods:

vite_client_tag
js_link asset("main.js"), type: "module"
css_link asset("main.css") unless LuckyEnv.development?

The example above does the exact same thing as vite_entry_tags.

Using React

If you're using React with the @vitejs/plugin-react plugin, you need to add the vite_react_refresh_tag method before any other asset tags to inject the refresh runtime served by Vite:

vite_react_refresh_tag
vite_client_tag
# ...

Static assets

LuckyVite manages the asset pipeline by overwriting Lucky's asset and dynamic_asset macros.

img src: asset("@images/logo.png")

Note: The asset helper uses Vite's aliases for easier referencing. Aliases can be configured in config/lucky_vite.json.

Configuration

Lucky and Vite share some information which is managed through the config/lucky_vite.json file. It comes with the following defaults:

{
  "aliases": ["css", "fonts", "images", "js"],
  "outDir": "public/assets",
  "root": "src/js",
  "entry": "entry",
  "host": "127.0.0.1",
  "port": 3010
}

Here's a bit more info about the available properties:

Note: Not all Vite's configuration options are recognised here as this file covers that's shared between Vite and Lucky. You can add other Vite-specific configuration options directly in vite.config.js.
