Usage

Flarebase tries to use the same method names and return values as the official Firebase/Admin SDK. Sometimes, the method signature are slightly different.

Create FlarebaseAuth

`ts
import { FlarebaseAuth } from 'flarebase-auth';

const auth = new FlarebaseAuth({
apiKey: 'Firebase api key',
projectId: 'Firebase project id',
privateKey: 'Firebase private key or service account private key',
serviceAccountEmail: 'Firebase service account email',
});
`

Sign-in with email/pass

`ts
//Sign in with username and password
const { token, user } = await auth.signInWithEmailAndPassword(
'my@email.com',
'supersecurepassword'
);

const userEmail = user.email;
const refreshToken = token.refreshToken;
`

Sign-up with email/pass

`ts
//Sign up with username and password
const { token, user } = await auth.signUpWithEmailAndPassword(
'my@email.com',
'supersecurepassword'
);

const userEmail = user.email;
const refreshToken = token.refreshToken;
`

Create session cookies

`ts
//Create a new session cookie from the user idToken
const { token, user } = await auth.signInWithEmailAndPassword(
'my@email.com',
'supersecurepassword'
);

const sessionCookie = await auth.createSessionCookie(token.idToken);
`

Verify session cookies

`ts
auth
.verifySessionCookie(sessionCookie)
.then((token) => useToken(token))
.catch((e) => console.log('Invalid session cookie'));
`

Cache OAuth tokens with Cloudflare KV

`ts
import { FlarebaseAuth, CloudflareKv } from 'flarebase-auth';

const auth = new FlarebaseAuth({
apiKey: 'Firebase api key',
projectId: 'Firebase project id',
privateKey: 'Firebase private key or service account private key',
serviceAccountEmail: 'Firebase service account email',
cache: new CloudflareKv(NAMESPACE),
});
`

Test environment

If you want to test this library, have a look at /src/test.env.example.json.
Create a new file in the same directory called test.env.json with the real values and
run the tests with npm test

`json
{
"FIREBASE_TEST_CREDENTIALS": {
"apiKey": "MY FIREBASE API KEY",
"projectId": "FIREBASE PROJECT ID",
"privateKey": "FIREBASE PRIVATE KEY OR SERVICE ACCOUNT PRIVATE KEY",
"serviceAccountEmail": "FIREBASE SERVICE ACCOUNT EMAIL"
},

"FIREBASE_TEST_USER": {
"email": "test@test.com",
"password": "password123"
}
}
`
