modern web app build

shahab10 months ago

Hello,
I have installed modern web app and traccar backend code on local machine from github and was able to run on it by doing "npm start" on web app
But when i do "npm run build" and "server -s build" frontend show error(image attached below)
https://ibb.co/sWh0THM
later on investigation i found that when frontend load it makes a GET request to http://localhost:3000/api/server
Now when i do "npm start" this api return the server information and works fine but when i do "serve -s build" i.e run build files, it is returning me an HTML page

<!doctype html><html lang="en"><head><meta charset="utf-8"/><link rel="icon" href="/favicon.ico"/><meta name="viewport" content="width=device-width,initial-scale=1"/><meta name="theme-color" content="#1a237e"/><meta name="description" content="GPS tracking system"/><link rel="apple-touch-icon" href="/logo192.png"/><link rel="manifest" href="/manifest.json"/><link rel="stylesheet" href="/styles.css"><title>Tracker</title><script defer="defer" src="/static/js/main.c1b28d2f.js"></script><link href="/static/css/main.becf9d2c.css" rel="stylesheet"></head><body><noscript>Enable JavaScript to use <a href="https://www.traccar.org//">GPS Tracking System</a>.</noscript><div id="root" class="root"></div></body></html>

This causing error in parsing the respose and showing the error. why web app is working fine on npm start but not serve -s build while in both case traccar backend code is running?

For my particular use case
I have Updated modern web app interface and also develop separate custom backend along with traccar backend. Now i have to host web app on a separate ec2 and since it is react i want start server with react build folder

Where did you get the server -s build from?

OK. That's the standard output of the tools we're using. You can't actually deploy it like that. You have to deploy it in Traccar.

Hello,
I followed the directions after downloading. I am on Ubuntu Linux 22.04. After installing using npm install, I then run npm start, but I get the following error:

Are you sure you're running it from the correct folder?

Apologies. I misread the directions. It's running for me now.
