Build Web3 at Lightning Speed

Juno is a blockchainless (or zero-knowledge) development platform for creating innovative applications.

// Import functions from the JavaScript SDK.
import { signIn, signOut, authSubscribe, 
    InternetIdentityProvider 
} from "@junobuild/core";

// Subscribe to changes in the user state at
// the top level of your app.
authSubscribe((user) => {
  console.log("User is defined or null:", user);
});

// Sign-in with the default function
<button onClick={signIn}>Sign-in</button>

// Or sign in with custom options,
// like specifying a specific provider.
await signIn({
  provider: new InternetIdentityProvider({
    domain: "ic0.app"
  })
});

// Obviously, sign-out is also supported
await signOut();

// Automatically sign out users when their session expires
// by initializing the library with a watcher worker.
await initSatellite({
  workers: {
    auth: true
  }
});

I know you will love it when you try it out. I was amazed by how it is very easy to deploy an app on Juno.

I’m still amazed at how Juno has simplified the development process on ICP. It’s like a magic wand for devs - I get to focus on frontend and Juno handles the rest.

Thanks to Juno's well-documented get-started guide, we had it up and running in under 5 minutes. Our first decentralized analytics tool is now live and kicking!

Juno enables easy dapp deployment across multiple UI frameworks including SvelteKit. ICP teams such as StackICP are using it to speed up their development.
