Picket React SDK

The Picket React SDK, picket-react, is a JavaScript library for integrating Picket into React apps. It gives access to a Picket context provider and custom hook for securing your app.

Installation

picket-react is an npm package.

npm install "@picketapi/picket-react"

Usage

The PicketProvider creates a Picket context, which makes user authentication information available throughout your app! It takes a publishable API key as a prop.

import { PicketProvider } from "@picketapi/picket-react"

function MyApp({ children }) {
  return (
    <PicketProvider apiKey="YOUR_PUBLISHABLE_KEY_HERE">
      {children}
    </PicketProvider>
  );
}

We’ve placed a placeholder publishable API key in this example. Replace it with your actual publishable API key. After instantiating the PicketProvider, you can use the usePicket hook to get user authentication information within your app. Below is an example of a component that renders different information based on the user's authentication state.

import { usePicket } from "@picketapi/picket-react"

const MySecurePage = () => {
  const { 
          isAuthenticating, 
          isAuthenticated, 
          authState, 
          logout,
          login
          } = usePicket();
  
  // user is logging in
  if (isAuthenticating) return "Loading";

  // user is not logged in
  if (!isAuthenticated) {
      return (
        <div>
            <p>You are not logged in!</p>
            <button onClick={() => login()}>Login with Wallet</button>
        </div>
      )
  }

  // user is logged in 🎉
  const { user } = authState;
  const { walletAddress } = user;
  
  return (
    <div>
       <p>You are logged in as {walletAddress} </p>
       <button onClick={() => logout()}>Logout</button>
    </div>
  )
}

The usePicket hook provides your components information about the user's authentication state. You can use it to require authentication on specific routes, get user information, or get the login and logout functions.
