Build ideas in

Juno is an open-source, next-gen serverless platform that helps developers build and ship secure projects at scale.

A screenshot of the Juno Console application

// 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!

If you're looking to start building on ICP, you definitely need to check out Juno! It's been a game-changer for me.

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