Javascript JWT Simple Server client library

Home Repository:

https://github.com/Xabaril/JWTSimpleServer

NPM - Installing the library

npm install jwt-simpleserver-client --save

The typescript library will allow you to easily interact will the token endpoint.

Follow this steps to create your client if you are using the browser bundled library:

1. Create the client options

var defaultServerOptions = new JwtSimpleServer.ClientOptions();

Client options parameters have default values listed in this table:

Parameter	default value
tokenEndpoint	"/token"
host	window.location.origin
httpClient	XMLHttpRequestClient

NOTE: You can implement your own HttpClient by implementing our HttpClient abstract class

2. Creat the client providing the options object:

var simpleServerClient =  new JwtSimpleServer.ServerClient(defaultServerOptions);

3. Request an access token by executing requestAccessToken method:

simpleServerClient.requestAccessToken({ userName: "demo", password: "demo" })
	.then(token => {
     // your token object will have the access token and expiral, and if configured: the refresh token
   }):

*Client events

JWT client have several observables you can subscribe to:

Observable	return value	description
onBeforeRequestAccessToken	void	Will notify observers before starting the token request to the server
onRequestAccessTokenSuccess	Token	Will notify observers passing the retrieved token as parameter
onBeforeRequestRefreshToken	void	Will notify observers before starting the refresh token request to the server
onRequestRefreshTokenSuccess	Token	Will notify observers passing the retrieved refresh token as parameter

4. Optional: If you want the library to request new access tokens given an interval you can configure the RefreshTokenService

var refreshService = new JwtSimpleServer.RefreshTokenService(simpleServerClient);

let onTokenRefreshedFunction = (token) => {
   console.log("Refresh token service:", token);
}

//Start the renewal service
refreshService.start({
   intervalSeconds: 10,
   refreshToken,
   onRefreshTokenSuccessCallback: onTokenRefreshedFunction
});

//Stop the renewal service
refreshService.stop();
