Plug & Play Authentication.

Juno Authentication ensures deep integration with services like Datastore and Storage, offering a cohesive ecosystem.

You can manage your users in an administration console. A new entry is automatically created when a user successfully signs in.

import { signIn } from "@junobuild/core";

<button onClick={signIn}>Sign-in</button>

Efficient Libraries.

Juno offers advanced blockchain capabilities via user-friendly JavaScript libraries, enabling seamless integration into your frontend projects.

import { setDoc } from "@junobuild/core";

await setDoc<Example>({
  collection: "my_collection_key",
  doc: {
    key: "my_document_key",
    data: myExample,
  },
});

Developer-Focused Tools.

Designed by developers for developers, Juno's tools and console empower you to manage your dApps, monitor, and administrate your data.

Utilize the convenient CLI or GitHub Actions to deploy your projects with ease.

❯ npm i -g @junobuild/cli
❯ juno deploy

Serverless Functions.

Enhance Juno's capabilities with strongly-typed hooks, automatically triggered to execute custom logic on your smart contract.

#[derive(Serialize, Deserialize)]
struct Person {
    hello: String,
    amount: DocDataBigInt,
}

#[on_set_doc]
fn on_set_doc(context: OnSetDocContext) -> Result<(), String> {
  let data: Person = decode_doc_data(&context.data.data.after.data)?;

  print(format!("Caller: {}", context.caller.to_text()));
  print(format!("Data: {}", amount.value));
}
