javascript - signInWithEmailAndPassword and EmailAuthProvider -

i trying understand new authentication model. trying convert web code used older authwithpassword.

considering had:

firebase.authwithpassword({email: email, password: password }).then(    authdata => console.log('auth: authwithpassword success '+authdata.uid),     err => console.log('auth: authwithpassword fail: '+err)); 

how achieve same thing new version ?

there seem 2 different interfaces:

auth().signinwithemailandpassword

and

firepad.auth.emailauthprovider

but don't understand difference or how use them. there clear example correct way email authentication ?

there lot of such differences new api. best stick closely docs.

the new docs site has guide on email/password authentication, specific question code:

firebase.auth().signinwithemailandpassword(email, password).catch(function(error) {   // handle errors here.   var errorcode = error.code;   var errormessage = error.message;   // ... });
