Sometimes when using Node.js for your application(s) you may receive an error about the app being unable to “GET a URL”.
This is because of how Passenger uses Application URLs in cPanel, which can be fixed by changing where they are set up in either Phusion or NPM config files as needed!
For example, if the Application URL text box is set to ‘webapp’ then the root path for the application is not “/” but is actually “/webapp”.
This behavior differs from most other web environments where /path typically denotes a directory and “index.js” file located within that directory.”
This Knowledgebase article will cover how to resolve this error. How can one fix node js app error message: ‘Cannot GET’ url?
How to fix the error Node.js application error message: “Cannot GET” URL
To fix this error, you need to include the application URL in your routes. The following code sample demonstrates how to do so using popular Express web framework. It assumes that the Application text box in Node.js cPanel is set to webapp:
const express = require('express');
const app = express();
app.get('/webapp/', function(req, res){
res.send("Hello from the root application URL");
});
app.get('/webapp/test/', function(req, res){
res.send("Hello from the 'test' URL");
});
app.listen(0, () => console.log('Application is running'));
In this demonstration, two routes are defined: /webapp and /webapp/test. If your domain name is mycompanywebsite.com, when you visit http://mycompanywebsite.com/webapp or http://mycompanywebsite.com/webapp/test in a web browser the pages load as expected but if you visit any other URL under http://mycompanywebsite.com it gives Cannot GET error message.
