Vercel Deployment - A Simple Guide To Deploy Your Projects

Introduction

When we build a website or web application, we usually develop and test it on our own computer first.

For example, while developing a project, we might access it through:

http://localhost:3000

This works on our computer, but other people cannot normally access it.

To make our project available on the internet, we need to deploy it.

There are many platforms available for deployment, and Vercel is one of the most popular choices for modern web applications.

In this blog, we will understand what Vercel is, why developers use it, what we need before deployment, and how to deploy a project step by step.

1. What is Vercel?

Vercel is a cloud platform used to deploy and host web applications.

In simple words, Vercel takes your project code, builds it, hosts it on its servers, and makes it accessible through the internet.

Instead of manually setting up a server and configuring everything yourself, you can connect your project to Vercel and deploy it with just a few steps.

For example:

Your Project
     ↓
GitHub
     ↓
Vercel
     ↓
Build & Deploy
     ↓
Website Available Online

Vercel is especially popular for projects built using:

  • Next.js
  • React
  • JavaScript
  • TypeScript
  • Vite
  • Other modern web frameworks

2. Why Do We Use Vercel?

Suppose you have created a website on your laptop.

You can run it locally, but if you want your friends, customers, or users to access it, the project needs to be hosted somewhere on the internet.

You could manually configure a server, but that requires more technical knowledge.

Vercel simplifies this process.

Some useful features include:

  • Easy deployment
  • GitHub integration
  • Automatic deployments
  • Environment variable management
  • Custom domain support
  • HTTPS
  • Deployment logs
  • Preview deployments

For developers who are building modern web applications, this makes deployment much easier.

3. What Do We Need Before Deploying?

Before deploying a project to Vercel, you should have:

1. A completed project

For example:

my-project/
├── app/
├── public/
├── package.json
└── ...

The exact structure depends on the technology you are using.

2. GitHub repository

Your project should ideally be pushed to GitHub.

For example:

GitHub
   └── my-project

Vercel can connect directly to this repository.

3. Vercel account

You need a Vercel account to create and manage your deployments.

4. Environment variables

If your project uses things like:

  • API keys
  • Database URLs
  • Authentication secrets
  • Payment gateway keys
  • Firebase configuration
  • Other private configuration

you may need to add them to Vercel.

4. Push Your Project to GitHub

Before deploying, let's assume our project is already on GitHub.

If your project isn't pushed yet, a basic Git workflow looks like:

git init
git add .
git commit -m "Initial commit"
git branch -M main
git remote add origin YOUR_GITHUB_REPOSITORY_URL
git push -u origin main

After pushing, your project will be available in your GitHub repository.

For example:

GitHub
   ↓
Your-website

Now Vercel can access the project.

5. Create a Vercel Account

Go to the Vercel website and create an account.

You can sign in using GitHub, which makes connecting your repositories easier.

After logging in, you will see the Vercel dashboard.

From the dashboard, you can create a new project and connect it to your GitHub repository.

6. Import Your GitHub Project

In the Vercel dashboard, choose the option to create a new project.

Vercel will show the GitHub repositories available to you.

Find the repository you want to deploy.

For example:

Your-website

Select the repository and choose Import.

Vercel will then analyze your project and try to identify the framework being used.

For example, if your project is a Next.js application, Vercel may automatically detect:

Framework Preset: Next.js

In many cases, Vercel automatically fills in the required build settings.

7. Configure Your Project

Before clicking the final deployment button, you may see some configuration options.

The important ones are:

Project Name

This is the name of your Vercel project.

Framework Preset

Vercel tries to automatically detect your framework.

For example:

Next.js

Root Directory

This tells Vercel where your project is located.

For most projects, you can leave it as the default.

Build Settings

Vercel usually detects the appropriate settings automatically.

For example, a Node.js project may use:

npm run build

If Vercel has detected everything correctly, you usually don't need to change these settings.

8. Add Environment Variables

This is one of the most important steps when deploying a real project.

During development, you may have a file such as:

.env.local

Inside it, you might have:

NEXT_PUBLIC_FIREBASE_API_KEY=xxxxx
RAZORPAY_KEY_ID=xxxxx
RAZORPAY_KEY_SECRET=xxxxx

These values are used by your application, but they should not simply be uploaded to GitHub, especially when they contain secrets.

Instead, add the required environment variables to your Vercel project.

For example:

Name:
RAZORPAY_KEY_SECRET

Value:
your-secret-value

You may need to add multiple variables depending on your project.

For example, our Your  website used services such as Firebase and Razorpay, so the deployment required the appropriate configuration values to be available in the Vercel environment.

Important

Do not expose private keys or secret credentials in your GitHub repository.

Use environment variables for sensitive configuration.

9. Deploy the Project

Once your project settings and environment variables are ready, click:

Deploy

Vercel will then start the deployment process.

In simple terms, Vercel will:

Get Your Code
      ↓
Install Dependencies
      ↓
Build Your Project
      ↓
Deploy Your Application
      ↓
Give You a URL

You will be able to see the deployment progress in the Vercel dashboard.

If everything succeeds, you will see a successful deployment.

10. Open Your Deployed Website

After deployment, Vercel provides a URL for your project.

It will look similar to:

https://your-project.vercel.app

Open that URL in your browser.

Your project is now available on the internet.

This is the main difference between:

localhost:3000

and:

your-project.vercel.app

The first is your local development environment.

The second is your deployed application.

11. Connect Your Own Domain

Vercel also allows you to connect a custom domain.

For example, instead of:

your-project.vercel.app

you could use:

yourwebsitename.com

The general process is:

Own a Domain
      ↓
Add Domain in Vercel
      ↓
Configure DNS
      ↓
Verify Domain
      ↓
Website Opens Using Your Domain

This is especially useful for business websites because a custom domain looks more professional and is easier for users to remember.

12. What Happens When We Update the Code?

One of the best things about Vercel is its GitHub integration.

Suppose you deploy your project today.

Tomorrow, you make some changes and push them to GitHub:

git add .
git commit -m "Updated website"
git push

Vercel can automatically detect the new changes and create a new deployment.

The workflow becomes:

Make Changes
     ↓
Git Push
     ↓
GitHub
     ↓
Vercel Detects Changes
     ↓
Build
     ↓
New Deployment

This means you don't have to manually upload your project every time you make an update.

13. What If the Deployment Fails?

Sometimes your project may not deploy successfully.

You might see an error such as:

Build Failed

Don't panic.

Vercel provides deployment logs that show what went wrong.

Some common reasons are:

  • Missing environment variables
  • Build errors
  • Missing packages
  • Incorrect configuration
  • Incorrect Node.js version
  • Code errors
  • Incorrect file paths

For example, if your application expects:

DATABASE_URL

but you forgot to add it to Vercel, your application may fail.

So whenever a deployment fails, the first thing you should do is check the deployment logs and read the actual error.

14. Vercel Deployment: The Complete Flow

After understanding everything, the complete process is actually quite simple:

Build Your Project
        ↓
Push Project to GitHub
        ↓
Create Vercel Account
        ↓
Import GitHub Repository
        ↓
Check Project Settings
        ↓
Add Environment Variables
        ↓
Click Deploy
        ↓
Vercel Builds Project
        ↓
Deployment Successful
        ↓
Get Vercel URL
        ↓
Connect Custom Domain (Optional)

Conclusion

Vercel makes deploying a modern web application much easier.

Instead of manually configuring a server, we can connect our GitHub repository to Vercel, configure the required settings and environment variables, and deploy the project.

The most important things to remember are:

  • Vercel → Platform used to deploy and host web applications.
  • GitHub → Where we store our project code.
  • Environment Variables → Used to provide configuration and sensitive values securely.
  • Deployment → Makes our project available on the internet.
  • Custom Domain → Allows us to use our own website address.
  • Automatic Deployment → Vercel can redeploy the project when we push new changes to GitHub.

Once you understand this workflow, deploying your next project through Vercel becomes a straightforward process.
