Trying to set up Shopify node app on server

Shopify Discussion

Topic summary

A developer successfully built a Shopify Node.js app that works locally but encounters backend issues when deployed to an AWS EC2 server.

What’s Working:

  • Frontend build (created via npm run build) deploys successfully to the server’s HTML folder
  • Frontend is accessible and functional

Current Problems:

  • Backend APIs are not responding on the server
  • Shopify login/authentication fails on the deployed version
  • The app only functions with npm run dev (localhost URL), which doesn’t work for server deployment
  • Running npm run serve directly on the web folder also fails

Technical Context:

  • Node version: 18
  • CLI version: 3.50
  • An image was shared (likely showing configuration or error details)

The developer is seeking guidance on properly configuring the Node.js backend to run on AWS EC2 alongside the deployed frontend.

I have created a shopify app with node template. It is working on my localhost but backend is not working on AWS server.

Steps: I created frontend build using npm run build. It created dist folder in frontend. Then I uploaded dist folder content in server html folder and updated urls in Shopify app. The Frontend worked, but the backend APIs are not working.

Issue:- On server, shopify login is not working as it creates localhost url on npm run dev and web folder is not working directly as well if I run npm run serve. So I am unable to find a way to make the node backend work on AWS ec2 server.

node version: 18

CLI version: 3.50
