Deploying a Hello World Application ​

This guide will walk you through deploying a simple Hello World application using Tanjun to a VPS.

Prerequisites ​

  • A VPS reachable with SSH Key Authentication

Create a new Tanjun project ​

Create a new empty folder and create a index.js file in it.

js
const http = require('http');

http.createServer((request, response) => {
    response.writeHead(200, {
        'Content-Type': 'text/plain'
    });
    response.write('Hello, World!\n');
    response.end();

}).listen(3000);

This is our Node.js Hello World application. It listens on port 3000 and returns a simple text response.

To deploy it we need to create a new Tanjun project using the following command:

bash
tanjun init

This will ask you a few questions about your project and create a new project directory with the necessary files.

Prepare your VPS for deployment ​

Next, you will need to prepare your VPS for deployment. You can do this by running the following commands:

bash
tanjun setup

This will check if Docker is installed, when not it will install it for you. It will also deploy a new Docker Container with listing to Port 80 and 443 to the VPS.

Deploy your application ​

Now that your VPS is ready, you can deploy your application by running the following command:

bash
tanjun deploy

This will automatically discover that the Project is using Node.js and build a proper Docker Image for it. It will then deploy the Docker Image to your VPS and start it and your application will be live at the given URL.
