### Installing Casdoor React SDK

Source: https://github.com/casdoor/casdoor-react-sdk/blob/master/README.md

This snippet provides commands for installing the `casdoor-react-sdk` using both npm and yarn package managers. It's the first step to integrate the SDK into a React project.

```Shell
#NPM
npm i casdoor-react-sdk

#YARN
yarn add casdoor-react-sdk
```

### Initializing Casdoor SDK in React

Source: https://github.com/casdoor/casdoor-react-sdk/blob/master/README.md

This snippet demonstrates how to initialize the Casdoor SDK with necessary configuration parameters such as `serverUrl`, `clientId`, `appName`, `organizationName`, `redirectPath`, and `signinPath`. This configuration is crucial for the SDK to communicate with the Casdoor server.

```TypeScript
import Sdk from "casdoor-js-sdk";

export const ServerUrl = "http://localhost:7023";

const sdkConfig = {
  serverUrl: "http://localhost:8000",
  clientId: "d79fd3c4e09a309fb3f5123",
  appName: "application_hnpzib",
  organizationName: "organization_4emn5k",
  redirectPath: "/callback",
  signinPath: "/api/signin"
};

export const CasdoorSDK = new Sdk(sdkConfig);
```

### Implementing Silent Sign-in with Casdoor in React

Source: https://github.com/casdoor/casdoor-react-sdk/blob/master/README.md

This snippet demonstrates how to use the `SilentSignin` component on a home page to perform a silent login if required. It checks if silent sign-in is needed and provides callbacks for success (`handleReceivedSilentSigninSuccessEvent`) and failure (`handleReceivedSilentSigninFailureEvent`) events.

```TSX
import * as Setting from "./Setting";
import { SilentSignin, isSilentSigninRequired } from "casdoor-react-sdk";

function HomePage() {
  const isLoggedIn = () => {
    return localStorage.getItem("token") !== null;
  };

  if (isSilentSigninRequired()) {
    // if the `silentSignin` parameter exists, perform silent login processing
    return (
      <SilentSignin
        sdk={Setting.CasdoorSDK}
        isLoggedIn={isLoggedIn}
        handleReceivedSilentSigninSuccessEvent={() => {
          // jump to the home page here and clear silentSignin parameter
          window.location.href = "/";
        }}
        handleReceivedSilentSigninFailureEvent={() => {
          // prompt the user to log in failed here
          alert("login failed");
        }}
      />
    );
  }

  const renderContent = () => {
    if (isLoggedIn()) {
      return <div>Hello!</div>;
    } else {
      return <div>you are not logged in</div>;
    }
  };

  return renderContent();
}
```

### Handling Casdoor Authentication Callback in React

Source: https://github.com/casdoor/casdoor-react-sdk/blob/master/README.md

This snippet shows how to use the `AuthCallback` component to intercept the `/callback` path. It handles the server interaction logic for obtaining a token after a successful authentication. It requires implementing `saveTokenFromResponse` to store the token and `isGetTokenSuccessful` to validate the server's response.

```TSX
import { Route, BrowserRouter, Routes } from "react-router-dom";
import { AuthCallback } from "casdoor-react-sdk";
import * as Setting from "./Setting";
import HomePage from "./HomePage";

function App() {
  const authCallback = (
    <AuthCallback
      sdk={Setting.CasdoorSDK}
      serverUrl={Setting.ServerUrl}
      saveTokenFromResponse={(res) => {
        // @ts-ignore
        // save token
        localStorage.setItem("token", res.data.accessToken);
      }}
      isGetTokenSuccessful={(res) => {
        // @ts-ignore
        // according to the data returned by the server,
        // determine whether the `token` is successfully obtained through `code` and `state`.
        return res.success === true;
      }}
    />
  );

  return (
    <BrowserRouter>
      <Routes>
        <Route path="/callback" element={authCallback} />
        <Route path="/" element={<HomePage />} />
      </Routes>
    </BrowserRouter>
  );
}

export default App;
```
