PASSPORT JWT FIREBASE

This Library helps you use JWT Strategy with Passport and Firebase Auth

Usage of this Library is very simple

Functions

async TokenLoader.Load(timeout = 2 hours in MS)

Used to Load Google Auth tokens

Updates Token List every 2 hours by default

If Tokens don't match during checking, tokens get updated again

Not mandatory to call this method although first time check may fail if not called

FirebaseStrategy

Main Strategy used. Link it with passport using passport.use(new FirebaseStrategy());

constructor(options: JWTStrategyOptions, verfiedCallback)

Both Parameters are Optional

Pass JWT Strategy Options as the First param and pass callback function about what to do when verfied

EXAMPLES

import express, { Application, Request, Response } from "express";
import bodyParser from "body-parser";
import passport from "passport";
import FirebaseStrategy, { TokenLoader } from "passport-jwt-firebase";

TokenLoader.Load(); // Note is Async
const app: Application = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

passport.use(new FirebaseStrategy());
app.use(passport.initialize());
app.use(passport.authenticate("jwt", { session: false }));

app.use(
  "/",
  passport.authenticate("jwt", { session: false }),
  (req: Request, res: Response) => {
    if (req.isUnauthenticated()) return res.status(401);
    const user = {
      ...req.user!,
      authenticated: req.isAuthenticated(),
    };
    console.log(user);
    return res.json(user);
  }
);

const Port = Number(process.env.PORT || 8000);
app.listen(Port, (err) => {
  if (err) {
    return console.error(err);
  }
  console.log(`Server is listening on ${Port}`);
  console.log(`To Query, send Bearer token to localhost:${Port}`);
  console.log(
    `Generate Firebase Bearer Token at https://pratikpc.github.io/google-firebase-auth-token/`
  );
});
