NodeJS

Feathers Cloud Auth requests can be verified in NodeJS with any framework.

HTTP

Below is a NodeJS server with a basic development CORS (necessary to allow requests from any client framework) configuration that uses the built in node:http module

import { createServer } from 'node:http';
import { createVerifier } from '@featherscloud/auth';

const appId = '<your-app-id>';
const verifier = createVerifier({ appId });

const defaultHeaders = {
  'Content-Type': 'application/json',
  'Access-Control-Allow-Headers': '*',
  'Access-Control-Allow-Methods': 'GET',
  'Access-Control-Allow-Origin': '*'
};

const server = createServer(async (req, res) => {
  if (req.method === 'OPTIONS') {
    res.writeHead(200, defaultHeaders);
    return res.end();
  }

  try {
    const header = req.headers.authorization;
    // Verify the Authorization header and get the user information
    const { user } = await verifier.verifyHeader(header);
    const response = {
      message: `Hello ${user.email} from node:http!`
    };

    res.writeHead(200, defaultHeaders);
    res.end(JSON.stringify(response));
  } catch (error) {
    res.writeHead(400, defaultHeaders);
    res.end(JSON.stringify({ error: error.message }));
  }
});

// Listen locally on port 3333
server.listen(3030, '127.0.0.1', () => {
  console.log(`NodeJS application ${appId} listening on http://localhost:3030`);
});

Express

The Express framework can handle request in a similar way.

npm install express
npm install cors

import express from 'express';
import cors from 'cors';
import { createVerifier } from '@featherscloud/auth';

const appId = '<your-app-id>';
const verifier = createVerifier({ appId });

const app = express();

app.use(cors());
app.get('/', async (req, res) => {
  try {
    const header = req.get('Authorization');
    // Verify the Authorization header and get the user information
    const { user } = await verifier.verifyHeader(header);
    const response = {
      message: `Hello ${user.email} from Express!`
    };

    res.status(200).json(response);
  } catch (error) {
    res.status(400).json({ error: error.message });
  }
});

app.listen(3030, '127.0.0.1', () => {
  console.log(
    `Express application ${appId} listening on http://localhost:3030`
  );
});
