Another solution is to actually create or login the user automatically if you already have the credentials handy. Here is how I do it using Plain JS.
function loginToFirebase(callback)
{
let email = '[email protected]';
let password = 'xxxxxxxxxxxxxx';
let config =
{
apiKey: "xxx",
authDomain: "xxxxx.firebaseapp.com",
projectId: "xxx-xxx",
databaseURL: "https://xxx-xxx.firebaseio.com",
storageBucket: "gs://xx-xx.appspot.com",
};
if (!firebase.apps.length)
{
firebase.initializeApp(config);
}
let database = firebase.database();
let storage = firebase.storage();
loginFirebaseUser(email, password, callback);
}
function loginFirebaseUser(email, password, callback)
{
console.log('Logging in Firebase User');
firebase.auth().signInWithEmailAndPassword(email, password)
.then(function ()
{
if (callback)
{
callback();
}
})
.catch(function(login_error)
{
let loginErrorCode = login_error.code;
let loginErrorMessage = login_error.message;
console.log(loginErrorCode);
console.log(loginErrorMessage);
if (loginErrorCode === 'auth/user-not-found')
{
createFirebaseUser(email, password, callback)
}
});
}
function createFirebaseUser(email, password, callback)
{
console.log('Creating Firebase User');
firebase.auth().createUserWithEmailAndPassword(email, password)
.then(function ()
{
if (callback)
{
callback();
}
})
.catch(function(create_error)
{
let createErrorCode = create_error.code;
let createErrorMessage = create_error.message;
console.log(createErrorCode);
console.log(createErrorMessage);
});
}
