I have 2 separate apps, a react-native
app and an express
backend server. I created the server using express-generator
. My server has the following code in users.js
router.get('/', function(req, res, next) {
res.json([{
id: 1,
username: "foo"
}, {
id: 2,
username: "bar"
}]);
});
The server is set to listen on port 8080 and have app.use('/users', users)
. Basically, just all of the code that comes with express-generator
.
In my react native app, I have: "proxy": "http://localhost:8080"
And then in App.js
:
componentDidMount() {
fetch('/users'
.then(res => res.json())
.then(users => this.setState({ users }))
}
I am using Expo to load my app on an Android device, and am getting: unexpected url: /users
. If I visit localhost:8080
in my browser, the data is visible, so I think that the issue must be on the client side.
You need to add the complete hostname and port number when making a request. You need to write complete url when getting data as http://localhost:8080/users in your App.js.
