Deploy a Node.js Project on Vercel: Shell and Git Instructions

Vercel is a cloud platform that allows you to deploy and manage applications. In this tutorial, we will cover how to deploy a Node.js project to Vercel using Git from the terminal. We will also explore the benefits of using Vercel and how it can improve your development workflow.

Benefits of Using Vercel

Vercel is a popular choice for deploying applications because of its ease of use, scalability, and performance. Here are some benefits of using Vercel:

• Easy Deployment: Vercel makes it easy to deploy your application with a single command. You don't need to worry about setting up servers or configuring infrastructure.

• Scalability: Vercel automatically scales your application to handle traffic spikes, so you don't need to worry about your application crashing under heavy load.

• Performance: Vercel uses a global content delivery network (CDN) to distribute your application, which means that your users will experience fast load times regardless of their location.

• Security: Vercel provides automatic SSL encryption and supports HTTP/2, which means that your application is secure and fast.

• Collaboration: Vercel makes it easy to collaborate with team members by providing a simple way to manage access and permissions.

Creating a New Project

In your terminal, create a new directory and initialize your project:

mkdir new-express-project
cd new-express-project
npm init -y

These commands create a new project directory and a package.json file with default settings.

Installing Express.js

Add Express to your project:

npm install express

Setting up your Express.js App

Create a directory named /api. Inside /api, create a file named index.ts. This will be your main server file.

Initializing an Express.js Server

Edit your index.ts with the following code to set up a basic Express.js server:

const express = require("express");
const app = express();
app.get("/", (req, res) => res.send("Express on Vercel"));
app.listen(3000, () => console.log("Server ready on port 3000."));
module.exports = app;

This code will:

• Define the base route /

• Return Express on Vercel when it’s called

• And start the Express.js server running on port 3000

Configuring your Project for Vercel

By using a vercel.json file, you can control how Vercel configures your application.

For our application, we’re going to tell Vercel to route all incoming requests to our /api folder.

To configure this, create a vercel.json file in the root of your project and add the following code:

{
  "version": 2,
  "rewrites": [{ "source": "/(.*)", "destination": "/api" }]
}

Running your Application Locally

You can replicate the Vercel deployed environment locally by using the Vercel CLI. This allows you to test how your application will run as if it were running on Vercel, even before you deploy.

To get started, you need to install the Vercel CLI by running the following command in your terminal:

npm install -g vercel

Next, login to Vercel to authorize the Vercel CLI to run commands on your Vercel account.

Now you use the local development command, which will also execute the vercel.json configuration you created above.

Running vercel dev will ask you some questions. You can answer however you like, but the defaults will suffice. This process will also create a new Vercel Project, but don’t worry, this will not make your Express.js app publicly accessible yet.

Deploying to Vercel

To deploy your application to Vercel, run the following command in your terminal:

vercel deploy

This command will deploy your application to Vercel.

Linking your Git Repository to Vercel

To link your Git repository to Vercel, run the following command in your terminal:

vercel link

This command will link your Git repository to Vercel.

Setting up Automatic Deployments

To set up automatic deployments, you need to configure your Git repository to deploy to Vercel on each push.

To do this, run the following command in your terminal:

vercel deploy --prod

This command will set up automatic deployments to Vercel on each push to your Git repository.

Benefits of Automatic Deployments

Automatic deployments provide several benefits:

• Efficiency: Automatic deployments save time and effort by eliminating the need to manually deploy your application.

• Consistency: Automatic deployments ensure that your application is deployed consistently every time.

• Quality: Automatic deployments reduce the risk of errors and improve the quality of your application.

• Collaboration: Automatic deployments make it easy to collaborate with team members by providing a simple way to manage access and permissions.
