See https://examples.waku.org/ for more examples.

Web Chat App

• code
• website
• Demonstrates: Group chat, React/TypeScript, Relay, Store.

Ethereum Private Messaging

End-to-end encrypted communication between two Ethereum addresses.

• code
• website
• Demonstrates: Private Messaging, React/TypeScript, Light Client, Signature with Web3, Asymmetric Encryption.

Waku Light Client in JavaScript

Send messages between several users (or just one) using light client targetted protocols.

• code
• website
• Demonstrates: Waku Light node: Filter + Light Push, Pure Javascript/HTML using ESM/unpkg bundle.

Minimal Angular (v13) Waku Relay

A barebone messaging app to illustrate the seamless integration of js-waku into AngularJS.

• code
• website
• Demonstrates: Group messaging, Angular, Waku Relay, Protobuf using protobufjs, No async/await syntax.

Waku Relay in JavaScript

This example uses Waku Relay to send and receive simple text messages.

• code
• website
• Demonstrates: Waku Relay, Pure Javascript/HTML using ESM/unpkg bundle.

Waku Relay in ReactJS

A barebone chat app to illustrate the seamless integration of js-waku into ReactJS.

• code
• website
• Demonstrates: Group chat, React/JavaScript, Waku Relay, Protobuf using protobufjs.

Using RLN in JavaScript

Rate limiting nullifier (RLN) is a construct based on zero-knowledge proofs that provides an anonymous rate-limited signaling/messaging framework suitable for decentralized (and centralized) environments

Use RLN in the browser, compatible with nwaku chat2 and go-waku chat2 RLN implementations.

• code
• website
• Demonstrates:
  • RLN:
    • Generate credentials
    • Insert membership to smart contract (Goerli testnet)
    • Retrieve smart contract state
    • Generate and send proofs
    • Verify incoming proofs
• Pure Javascript/HTML using ESM/unpkg bundle.

Using Waku Store in JavaScript

This example uses Waku Store to retrieve the latest ping relay message (used for keep alive purposes) and displays its timestamp.

• code
• website
• Demonstrates: Waku Store: Using a condition to stop retrieving results from Waku Store, Pure Javascript/HTML using ESM/unpkg bundle.

Minimal ReactJS Waku Store App

A simple app that retrieves chat messages using Waku Store to illustrate the retrieval of messages with js-waku and ReactJS.

• code
• website
• Demonstrates: React/JavaScript, Waku Store, Protobuf using protobufjs, no async/await syntax.

Continuous Integration

The master branch is being built by Jenkins CI: https://ci.infra.status.im/job/website/job/examples.waku.org/
