Overview of the Server

This is the API server to provide authentication API (Restful services) based JWT. It also shows how to push server notifications to clients via Socket.IO.

The simple implemenation show cases the following JWT and Socket.IO use cases:

• Upon user authentication, the user profile is signed and the jwt token is returned as response to the client. It's expected the jwt token will be included in the subsequent client requests (as authorization header).

• For subsequent client requests, the server will verify the jwt token extracted from the request headers.

• Invalid requests are considered unauthorized access and should be rejected.

• In addition, the server will push notifications (such as login/logout events) to the clients via Socket.IO.

Server Side Scripts

In order for the JWT based authentication and the server notifications to work, you need to run this API server. The client login/logout requests will be proxied to the API server, thanks to the create-react-app feature Proxying API Requests in Development.

In addition, the server will push notifications to the clients via Socket.IO.

Under this server directory, you can run (in a separate command line window):

npm install

This will install the dependencies for the server side.

npm run server

This will run the server on port 3001, which will be listening to the authentication requests (login/logout from the client), and pushes server notifications
