App Spec for Node + React in Single App

OK. The file below worked for me. The last problem was that I had not added my new app instance to the database pool allowed ip’s.

I’m using sequelize on the API server so there are a bunch of environment variables left out of the file below.

Hello!

App Platform supports adding multiple components from different repositories.

Here is an example of a sample app with multiple components (although in the same repo):

Repo: https://github.com/digitalocean/sample-monorepo Spec: https://github.com/digitalocean/sample-monorepo/blob/main/.do/app.yaml

All you would need to do is have a static site with the Github source pointing to your react repository, and a service with the Github source pointing to the nodejs repository.

The one thing you’ll need to be sure to modify is the routes for your app. For example if you want the frontend to be the root, you’d probably want to make the backend something like /api/... etc.

Happy Coding!
