@enkeldigital/firebase-authentication
Advanced tools
Library to create Express JS authentication and authorization middlewares
Plugin to use with this library to integrate with firebase authentication.

# Depends on this too
npm install create-express-auth-middleware
View samples folder for more specific examples
Make a API call from client using this example to include an Authorization header
Authorization: Bearer <your-client-token>
If an API call is made with a valid token, you can access the decoded token object from request
const app = require("express")();
const { create_authn_middleware, create_authz_middleware } = require("create-express-auth-middleware");
const firebaseAuthentication = require("@enkeldigital/firebase-authentication");
const { auth } = require("@enkeldigital/firebase-admin");
// Make all routes in this express app to be authentication protected.
// Meaning all routes defined later can only be called if a valid JWT is provided.
// This DOES NOT mean that routes are fully protected yet,
// as you need to ensure users have sufficient permission to access APIs using authorization middleware.
app.use(create_authn_middleware(firebaseAuthentication(auth)));
// The actual route that requires both authentication and authorization to run.
app.get(
"/data/:userID",
// Add authorization middleware to ensure users can only access their own data
// Checks that the specified userID in the URL matches user's own userID value in their 'DecodedIdToken'
// The 'jwt' property is set by the authentication middleware that is registered above
create_authz_middleware((req) => req.jwt.userID === req.params.userID),
// This request handler will only run if both predicate above returns true!
(req, res) => res.status(200).json({ data: "Protected user data" })
);
If authentication failed, you get a 401 code with the following response by default
{ "ok": false, "error": "Authentication Failed" }
If authorization failed, you get a 403 code with the following response by default
{ "ok": false, "error": "Authorization Failed" }
