React SDK - picket-react
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

npm install --save "@picketapi/picket-react"

Usage - Quick Start

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 πŸŽ‰
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.

PicketProvider

PicketProvider is a React context provider. It makes the Picket context available throughout your app and easily accessible via the usePicket hook.
It's typical to wrap the outer-most component with the PicketProvider to make a user's authentication and authorization state globally available to all child components.
import { PicketProvider } from "@picketapi/picket-react"
​
function MyApp({ children }) {
return (
<PicketProvider apiKey="YOUR_PUBLISHABLE_KEY_HERE">
{children}
</PicketProvider>
);
}

usePicket

usePicket is a wrapper around the useContext React hook that makes all Picket-related authentication information accessible.
import { usePicket } from "@picketapi/picket-react"
​
const MySecureComponent = () => {
const {
isAuthenticating,
isAuthenticated,
authState,
logout,
login
} = usePicket();
// do something with the user's authentication state
// redirect not logged in
// make API requests with access token
// display wallet address
// etc
return isAuthenticated ? "you've logged in 😎" : "you need to login 🚨";
}
