How to build a Vue app with Vite, Oak, and Deno

If you’re looking to build a modern web application using Vue.js, Vite, Oak, and Deno can be a great stack to work with. In this article, we will walk through the steps to set up a Vue app using these technologies.

Step 1: Install Deno

Deno is a secure runtime for JavaScript and TypeScript. To use it, you need to install Deno on your machine. Visit the Deno website (deno.land) and follow the instructions to install it.

Step 2: Set up a Vite app

Vite is a build tool specifically designed for development with Vue. To create a new Vite app, open your terminal and run the following command:

	
	deno run --unstable --import-map=import_map.json --allow-net [VITE_URL]
	
	

Replace [VITE_URL] with the URL of the Vite template you want to use. This will create a new Vite app in your current directory.

Step 3: Set up Oak

Oak is a middleware framework for Deno, which can be used for building web applications. To set up Oak, create a new file called server.ts in the root of your project and add the following code:

	
	import { Application } from "https://deno.land/x/oak/mod.ts";

	const app = new Application();

	app.use((ctx) => {
	  ctx.response.body = "Hello, Oak!";
	});

	await app.listen({ port: 8000 });
	
	

This code sets up a basic Oak server that listens on port 8000 and returns “Hello, Oak!” as the response. You can customize this to fit your needs.

Step 4: Connect Vite with Oak

To connect Vite with Oak, open your Vite app’s main.ts file and add the following code:

	
	import { createApp } from 'vue'
	import App from './App.vue'

	import { oakPlugin } from './oakPlugin.ts'

	const app = createApp(App)
	app.use(oakPlugin)

	app.mount('#app')
	
	

This code imports the Oak plugin and sets it up to be used with your Vue app. The oakPlugin function should be defined in oakPlugin.ts and should export a Vue plugin object.

Step 5: Start the server

To start the server, run the following command in your terminal:

	
	deno run --unstable server.ts
	
	

Now, your Vue app should be running at http://localhost:8000. You can access it in your web browser and start building your application.

With Vite, Oak, and Deno, you have a powerful and efficient stack to build your Vue app. Take advantage of the benefits these technologies offer and build amazing web applications.
