Getting a json back from express.js using a jQuery get method does not work
2
I am trying to pass a value as JSON from my back end to the front end of my application. I am currently running express.js and the connection for all post methods is PERFECT.
Upon a button click in the FRONT-END in my application I want to get back an invoice number from my server.
On the front end my code looks like this with jQuery:
$.get("/invoiceNumber", function(data) {
console.log(data.number);
});
On the back end it looks like this:
app.get("/invoiceNumber", function(req, res) {
res.json({ number: 4 });
});
Currently I am passing 4 just as a test.
The Error I am getting is:
GET http://127.0.0.1:3000/invoiceNumber 404 (Not Found)
If I try to go directly to:
http://127.0.0.1:3000/invoiceNumber
I get:
Cannot GET /invoiceNumber

it looks that this question is duplicated How to allow CORS?
So you can enable all cors requests with
npm install cors
your App.js
var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.get('/products/:id', function (req, res, next) {
res.json({msg: 'This is CORS-enabled for all origins!'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
you can find additional information here

Thanks for the time that you've put in helping me out Ishikawa, i'm trying to do all this to basically achieve this functionality: I'm usingexpress.jsand i have a server.js file in the root dir. of my project, and i have a public folder that i serve to the user's browser. I want to create a file in the root dir similar to the server.js (to be able to require NPM modules) that i can access from another file, in the public folder. If i try to do that right now i always getGET http://127.0.0.1:3000/invoices.js 404 (Not Found)I've tried ajax .get, plain .get, fetch full path, etc...

Looks to me like you need to refrence where you back end is running from:
$.get("/invoiceNumber", function(data) {
console.log(data.number);
});
if your express app is running on port 3000, change your front end to the following:
$.get("localhost:3000/invoiceNumber", function(data) {
console.log(data.number);
});

This allowed me to access the"localhost:3000/invoiceNumber"path in the browser, but i'm getting aAccess to XMLHttpRequest at 'localhost:3000/invoiceNumber' from origin 'http://127.0.0.1:3000' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.I'm also using Allow-Control-Allow-Origin: * to work around the Chrome restriction on localhost.

Yes, Cors is a cross origin restiction, if your on chrome theres a chrome extention called "Moesif CORS" which will disable CORS for you.

Looks to me like you need to refrence where you back end is running from:
$.get("/invoiceNumber", function(data) {
console.log(data.number);
});
if your express app is running on port 3000, change your front end to the following:
$.get("localhost:3000/invoiceNumber", function(data) {
console.log(data.number);
});

This allowed me to access the"localhost:3000/invoiceNumber"path in the browser, but i'm getting aAccess to XMLHttpRequest at 'localhost:3000/invoiceNumber' from origin 'http://127.0.0.1:3000' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.I'm also using Allow-Control-Allow-Origin: * to work around the Chrome restriction on localhost.

Yes, Cors is a cross origin restiction, if your on chrome theres a chrome extention called "Moesif CORS" which will disable CORS for you.
