How to Deploy Your NestJS Apps on Vercel

This article will guide you through the process of deploying your NestJS applications on Vercel, a popular platform for static site generation and serverless functions. We'll cover setting up your environment, configuring your project, and pushing it to Vercel for seamless deployment.

Deploying a NestJS application on Vercel can be an efficient way to get your app live without needing to manage a traditional server setup. In this guide, we'll walk through the steps necessary to deploy a NestJS application to Vercel.

Step 1: Set Up Your Environment

First, ensure you have Node.js installed on your machine. Next, create a new NestJS application if you haven't already done so. If you're using the CLI, run the following command:

npm init @nestjs/cli -y

Navigate into your project directory:

cd my-nestjs-app

Step 2: Install Dependencies

Make sure you have all the necessary dependencies installed. Run the following commands:

npm install

Step 3: Configure Vercel

Head over to the Vercel website (https://vercel.com) and log in with your GitHub or Google account. Click on "New Project" and then choose "From Git". Paste the URL of your NestJS repository. Alternatively, you can manually configure your project settings.

Step 4: Add Build Configuration

Vercel uses a build configuration file (.vercel.json) to customize how your application is built and deployed. Create a .vercel.json file in the root of your project directory with the following content:

{
  "version": 2,
  "builds": [
    {
      "src": "tsconfig.build.json",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/(.*)",
      "dest": "/index.html"
    }
  ]
}

Step 5: Customize Routes

In your src/main.ts file, add the following code to serve your NestJS application:

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
}
bootstrap();

Ensure that your routes are correctly set up to serve your NestJS application. This involves configuring your NestJS application to serve the correct files and directories.

Step 6: Commit and Push to Vercel

Commit your changes to your repository and push them to Vercel:

git add .
git commit -m "Add Vercel deployment configuration"
git push origin main

Step 7: Monitor and Deploy

After pushing your code to Vercel, you can monitor the deployment status and logs. Once your application is successfully deployed, you should see your NestJS application running on Vercel.

Additional Tips

• Environment Variables: Ensure your environment variables are correctly configured in Vercel's secrets management.
• Custom Domain: Vercel supports custom domains. Follow their documentation to set up a custom domain for your application.
• SSL Certificates: For production environments, consider obtaining SSL certificates and configuring Vercel to use them.

By following these steps, you can easily deploy your NestJS application to Vercel, leveraging Vercel's powerful features for static site generation and serverless functions.
