I need get apiKey to firebase app.
In documentation the example is:
var config = {
apiKey: '<your-api-key>',
authDomain: '<your-auth-domain>',
databaseURL: 'https://tecki.firebaseio.com/',
storageBucket: '<your-storage-bucket>'
};
firebase.initializeApp(config);
and look in the console, documentation and not where to find it .
Here's how I found it:
Under Projects using Firebase
click on the project you want to get the config for or click "Create new Project"
Click the red Add Firebase to your web app
button. See image below. Add Firebase to your web app button
Hope that helps.
Good luck.
