## Install

React Keycloak requires:

- React **16.0** or later
- `keycloak-js` **9.0.2** or later

```shell
yarn add @keycloak-react/web
```

or

```shell
npm install --save @keycloak-react/web
```

or as a `UMD` package through `unpkg`

- one for development: https://unpkg.com/@keycloak-react/web@latest/dist/umd/react-keycloak-web.js
- one for production: https://unpkg.com/@keycloak-react/web@latest/dist/umd/react-keycloak-web.min.js

## Support

| version | keycloak-js version |
| ------- | ------------------- |
| v2.0.0+ | 9.0.2+              |
| v1.x    | >=8.0.2 <9.0.2      |

## Getting Started

### Setup Keycloak instance

Create a `keycloak.js` file in the `src` folder of your project (where `App.js` is located) with the following content

```js
import Keycloak from 'keycloak-js'

// Setup Keycloak instance as needed
// Pass initialization options as required or leave blank to load from 'keycloak.json'
const keycloak = new Keycloak()

export default keycloak
```

### Setup KeycloakProvider

Wrap your App inside `KeycloakProvider` and pass the `keycloak` instance as prop

```js
import { KeycloakProvider } from '@keycloak-react/web'

import keycloak from './keycloak'

// Wrap everything inside KeycloakProvider
const App = () => {
  return <KeycloakProvider keycloak={keycloak}>...</KeycloakProvider>
}
```

**N.B.** If your using other providers (such as `react-redux`) it is recommended to place them inside `KeycloakProvider`.

`KeycloakProvider` automatically invokes `keycloak.init()` method when needed and supports the following props:

- `initConfig`, contains the object to be passed to `keycloak.init()` method, by default the following is used

      {
        onLoad: 'check-sso',
        promiseType: 'native',
      }

  for more options see [Keycloak docs](https://www.keycloak.org/docs/latest/securing_apps/index.html#init-options).

- `LoadingComponent`, a component to be displayed while `keycloak` is being initialized, if not provided child components will be rendered immediately. Defaults to `null`

- `isLoadingCheck`, an optional loading check function to customize LoadingComponent display condition. Return `true` to display LoadingComponent, `false` to hide it.

  Can be implemented as follow

  ```js
  ;(keycloak) => !keycloak.authenticated
  ```

- `onEvent`, an handler function that receives events launched by `keycloak`, defaults to `null`.

  It can be implemented as follow

  ```js
  ;(event, error) => {
    console.log('onKeycloakEvent', event, error)
  }
  ```

  Published events are:

  - `onReady`
  - `onAuthSuccess`
  - `onAuthError`
  - `onAuthRefreshSuccess`
  - `onAuthRefreshError`
  - `onTokenExpired`
  - `onAuthLogout`

- `onTokens`, an handler function that receives `keycloak` tokens as an object every time they change, defaults to `null`.

  Keycloak tokens are returned as follow

  ```json
  {
    "idToken": string,
    "refreshToken": string,
    "token": string
  }
  ```

### HOC Usage

When a component requires access to `Keycloak`, wrap it inside the `withKeycloak` HOC.

```js
import { withKeycloak } from '@keycloak-react/web'

const LoginPage = ({ keycloak, keycloakInitialized }) => {
  // Here you can access all of keycloak methods and variables.
  // See https://www.keycloak.org/docs/latest/securing_apps/index.html#javascript-adapter-reference
  return (
    <div>
      <button type="button" onClick={() => keycloak.login()}>
        Login
      </button>
    </div>
  )
}

export default withKeycloak(LoginPage)
```

### Hook Usage (React >=16.8 required)

Alternately, when a component requires access to `Keycloak`, you can also use the `useKeycloak` Hook.

```js
import { useKeycloak } from '@keycloak-react/web'

export default () => {
  // Using array destructuring
  const [keycloak, initialized] = useKeycloak()
  // or Object destructuring
  const { keycloak, initialized } = useKeycloak()

  // Here you can access all of keycloak methods and variables.
  // See https://www.keycloak.org/docs/latest/securing_apps/index.html#javascript-adapter-reference

  return (
    <div>
      <div>{`User is ${
        !keycloak.authenticated ? 'NOT ' : ''
      }authenticated`}</div>

      {!!keycloak.authenticated && (
        <button type="button" onClick={() => keycloak.logout()}>
          Logout
        </button>
      )}
    </div>
  )
}
```

### External Usage (Advanced)

If you need to access `keycloak` instance from non-`React` files (such as `sagas`, `utils`, `providers` ...), you can import the instance directly from the `keycloak.js` file.

The instance will be initialized by `react-keycloak` but you'll need to be carefull when using the instance and avoid setting/overriding any props, you can however freely access the exposed methods (such as `refreshToken`, `login`, etc...).

## Examples

See inside `examples` for various demo implementing this library main features.

**Note:** The demo apps are not meant to be **production-ready** nor **starter-kit** s but just a way to show this module components and their usage.
