express-jwt-proxy
An Express middleware to route login requests to an external authentication server and store JWT's and add them to headers en route to an external service.
Install
npm install express-jwt-proxy
Usage
const isProduction = process.env.NODE_ENV === 'production';
const apiPortDefault = isProduction ? 443 : 3000;
const apiPort = process.env.API_PORT || apiPortDefault;
const authConfig = {
api: {
endpoint: '/v1',
host: process.env.API_HOST || 'http://localhost',
port: process.env.API_PORT || apiPortDefault
},
auth: {
clientId: isProduction ? process.env.JWT_CLIENT_ID : undefined,
clientSecret: isProduction ? process.env.JWT_CLIENT_SECRET : undefined,
endpoint: `${process.env.AUTHENTICATION_HOST}/authenticate`
},
debug: !isProduction,
endpoint: '/api',
sessionStore: {
type: 'redis',
prefix: 'jwt-example',
secret: process.env.JWT_CLIENT_SECRET,
url: process.env.REDIS_URL
}
}
const app = new Express();
jwtProxy(app, authConfig);
You should then be able to use the following routes:
POST {config.apiPrefix}/login: Accepts a user object with email and password properties. These will be sent in a POST request to authenticationEndpoint and the response will contain an access_token which will be stored for that user's session.
POST {config.apiPrefix}/logout: Will destroy the record of that user's JWT from the session
{config.apiPrefix}/*: Will redirect to the configured API endpoint, appending the JWT stored in the session to the header
In your subsequent middleware, you'll be able to access the login state by using the following:
const loggedIn = res._headers['logged-in'] === "true";
