react-keycloak

a keycloak adapter for react with a protected route component that support react-router and reach-router

Installation

npm i @digital-wafa/react-keycloak

Usage

KeycloakProvider:

you should create an instance of keyclaok using the keycloak-js package or importing the link from your keycloak server directly which is recommanded to avoid compatibily issues.

const keycloakInstance = new Keycloak({
  url: "your keycloak url",
  realm: "your realm",
  clientId: "your client id",
  ....any other parameters
})

Then wrape your component with the keycloak provider, KeycloakProvider accept the following props :

import { KeycloakProvider } from "@digital-wafa/react-keycloak";


<KeycloakProvider
  keycloak={keycloak}
  loginOptions={{
    idpHint: "ei",
    scope: "phone",
  }}
>
  <App />
</KeycloakProvider>

finaly you can access the keycloak instance using the useKeycloakContext hook which return the following object:

{
  keycloak, // keycloak instance
  loginOptions, // keycloak login options
  initOptions, // keycloak init options
  authenticated // is the user authenticated or not
}

import { useKeycloakContext } from "@digital-wafa/react-keycloak";

const {keycloak, authenticated, loginOptions, initOptions} = useKeycloakContext();

or import the context if you are using a class component

import { keycloakContext } from "@digital-wafa/react-keycloak"

...

class YourClassComponent extends React.Component {
  static contextType = keycloakContext;
  const {keycloak, authenticated, loginOptions, initOptions} = this.context;
} 

NB: the token is refreshed automatically when it expire using the onTokenExpired event.

ProtectedRoute:

A useful component to protect your routes, it's compatible with react-router-dom and @reach/router

if the user is authenticated, he will see the desired page, if not he will be redirected to the keycloak login page.

react-router-dom example:

import { BrowserRouter as Router, Route } from 'react-router-dom';
import { ProtectedRoute } from "@digital-wafa/react-keycloak";

<Router>
    <ProtectedRoute
      RouteComponent={Route}
      ComponentToRender={YourPageComponent}
      path="/your-path"
    />
<Router>

@reach/router example:

when using @reach/router you don't need to use the ComponentToRender props

import { Router } from "@reach/router";
import { ProtectedRoute } from "@digital-wafa/react-keycloak";

<Router>
    <ProtectedRoute
      RouteComponent={YourPageComponent}
      path="/your-path"
    />
<Router>

getToken / getRefreshToken

Get the tokens which are stored automatically in localStorage after the login and the refreshToken actions. To use outside your components

import { getToken, getRefreshToken } from "@digital-wafa/react-keycloak";

const token = getToken();
const refreshToken = getRefreshToken()
