How to deploy Angular SSR app?

I have some questions regarding deployment. Sorry if some of it is very common knowledge, but I haven’t been able to find a good guide or explanation for this.

I want to deploy my Angular SSR (Angular Universal) app to DigitalOcean. I would like to use the App Platform (if possible) and deploy from Github where I have a repository with my code.

But I am in doubt about what to do and what options to choose…

First thing: The configuration says: “Node.js detected”.

• Web Service
• Static Site
• Worker

Which type should I select?

Can I select a free static site? Or should I have a paying plan to my Angular app? I already have a Node.js backend running as a Web Service on a paying plan.

I tried choosing a Web Service because I figured that it would be the right choice for a Server Side Rendered app.

But then the next dilemmas arise:

• HTTP Routes
• Build Command
• Run Command
• HTTP Port

What is the right things to enter for these?

My package.json file have these scrips:

"scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "build:prod": "ng build --prod && mv dist/APP-NAME _static",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "dev:ssr": "ng run APP-NAME:serve-ssr",
    "serve:ssr": "node dist/APP-NAME/server/main.js",
    "build:ssr": "ng build --prod && ng run APP-NAME:server:production",
    "prerender": "ng run APP-NAME:prerender"
  }

I guess it is “npm run build:ssr” for the build command. But I am not sure about the run command. Is it “npm run serve:ssr”?

And should HTTP Routes just be default “/” and HTTP Port be “8080”?

Can anyone please help me with this?
