Deploy a Nest JS app

Per Nest -

"Nest provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications. The architecture is heavily inspired by Angular."

Cleavr deploys Nest JS applications with minimal configurations required.

Prerequisite - ensure Port is not hardcoded

Creating a new Nest JS site via their CLI will add a hard coded port number for the app to listen on. You'll want to update this to listen to process.env.PORT as Cleavr randomly assigns port numbers for sites AND this will allow you to host multiple apps on your server.

In your Nest JS project, open the main.ts file and update as follows:

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

Step 1: Add A NodeJS SSR Site

On an existing server, click Add Site to add a new site to your server.

Select the NodeJS SSR option and enter the remainder site details and click Add to create the new site on your server.

Cleavr will automatically install NodeJS on your server if NodeJS has not already been installed.

Step 2: Configure Deployment Workflow

After the site has successfully installed, you'll now need to create a deployment workflow and deploy out your application.

In the deployment workflow section, you'll notice that a new deployment workflow was automatically created after the NodeJS site was added. This is a basic deployment workflow shell that you can use to complete the setup of your deployment workflow. Click on Complete Setup on the deployment workflow.

Configure the VC Provider, Repository, and Branch To Deploy fields on the Settings > Code Repository tab and then click Update.

Next, on the NPM Build tab, add the following:

• Entry Point: main.js
• Build Command: npm run build --production
• CWD Path: append /dist to the end Click Update.

Step 3: Deploy!

If everything looks good, go to the deployments section and deploy! 🚀
