How can I solve a Corss origin?, I'm calling localhost:3000/subscribers/ endpoint through react application which is running on localhost:3001

Miguel Alemán • Aug 7 '19

Hi, Vicente ! You can solve cross origin setting a header in your server definition.

res.header("Access-Control-Allow-Origin", "YOUR-DOMAIN");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

But if you want you can delegate that to a lib called "cors" that you can install: github.com/expressjs/cors#installa...

And that you can use simply by calling it as a Middleware.

var express = require('express')
var cors = require('cors')
var app = express()

app.use(cors())

It is important to remember that allowing cors without specifying a known domain could be dangerous since anyone would be able to reach your api, be careful and if you have any questions don't hesitate to ask :)

saludos, paisano !

Vicente Noriega • Aug 8 '19

Hey thanks man for some reason I was missing put my domain there, but now it's work fine.

I think app.listen(3004, () => console.log('server started')) should be app.listen(3000, () => console.log('server started'))

I love this article, great job!

Found a small error in the catch for the update subscriber, it's missing the (err) parameter part.

Thanks!

SUMIT SHARMA • Dec 4 '19

user == null doesn't work for me, instead I have to use user.length == 0. May be because I am noob.

Didin 👨‍💻 • May 18 '20

I think you can combine Express JS and dbdesigner.id as your database designer. This can make your project readable and clear documentation.

Saif5017 • Jan 1 '21

dude this has so far been the most useful tutorial i've ever followed

Another useful tool - github.com/dotenv-linter/dotenv-li....
It’s a lightning-fast linter for .env files. Written in Rust.

Not sure if you will get to see this considering how long it has been, but I having a problem with the middleware, for some reason it always returns "User not found", not sure why
