A Simple Approach to Deploying Your NestJS Application

Deploying a full-stack application can be overwhelming, especially if it's your first time venturing into the world of deployment. However, it doesn’t have to be complicated, particularly with the right tools and platforms. In this post, we'll walk through the easiest way to deploy your NestJS app with a Postgres database and a frontend HTML/JS application.

Understanding the Setup

When you develop locally, you may have created a structure like the following:

Your working application runs beautifully on your local machine using Docker containers for Postgres, Adminer, and your frontend app via an NGINX container. But now, you want to take your app online so others can access it even when your computer is off.

The Preferred Solution: Railway.app

Through some research and experimentation, many developers agree that Railway.app is an excellent platform for deploying applications without the hassle of traditional cloud providers like AWS or Azure. Here’s how to make it work:

Step-by-Step Deployment Process

Connect Railway.app to Your GitHub Repository:

The first step is to link Railway with the GitHub repository where your code is stored. This allows Railway to access your project files easily.

Utilize Dockerfiles:

Create and utilize Dockerfiles for both your NestJS API and frontend app. Railway.app automatically detects Dockerfiles in your project's main folders.

For your NestJS API, your Dockerfile should look something like this:

Set Up Postgres:

You need to create a separate Postgres database on Railway.app. Unlike your local setup where Postgres runs in a container, this is managed directly by Railway.

Update your application to use environment variables to differentiate between your local Docker Postgres instance and the Railway-hosted database.

Separate Your Frontend:

Best practices suggest keeping your frontend app as a separate project. Create a new repository for it, and move the frontend code out of your NestJS project.

You will need another Dockerfile for deploying your frontend app with NGINX:

Deploy Your Applications:

With your setup ready, you can deploy both your NestJS API and frontend app on Railway.app. Simply follow the prompts on Railway to build and run your applications.

Test and Ensure Everything Works

Once both applications are deployed successfully, make sure to test them thoroughly. Check:

API functionality.

Frontend responsiveness.

Database connections.

Conclusion: Simplifying Your Deployment Journey

Deploying your NestJS app alongside a Postgres database and a frontend doesn't have to be daunting. By using platforms like Railway.app and adhering to best practices in code organization, you can streamline the process significantly.

With these steps, your application can run online, providing users access anytime, anywhere. And the best part is, you can make adjustments and redeploy as needed without wrestling with complex server configurations.

Happy coding and deploying!
