Examples

Web Chat App (ReactJS)

A ReactJS web app is provided as an a show case of the library used in the browser.

A deployed version is available at https://status-im.github.io/js-waku/ Do note that due to some technical restrictions, it does not currently work out-of-the-box. If you wish to try it out, follow the instructions on the Vac forum. It is currently unstable and likely to break.

To run a development version locally, do:

git clone https://github.com/status-im/js-waku/ ; cd js-waku
npm install
npm run build
cd web-chat
npm install
npm run start

Then, you can use /help to change your nick and connect to a server.

CLI Chat App (NodeJS)

A node chat app is provided as a working example of the library. It is interoperable with the nim-waku chat app example. To run the chat app, first ensure you have Node.js v14 or above:

node --version

Then, install and run:

git clone https://github.com/status-im/js-waku/ ; cd js-waku
npm install
npm run chat -- --staticNode /ip4/134.209.139.210/tcp/30303/p2p/16Uiu2HAmPLe7Mzm8TsYUubgCAW1aJoeFScxrLj8ppHFivPo97bUZ

You can also specify an optional listenAddr parameter (.e.g --listenAddr /ip4/0.0.0.0/tcp/7777/ws). This is only useful if you want a remote node to dial to your chat app, it is not necessary in normal usage when you just connect to the fleet.

Build & Test

To build and test this repository, you need:

• Node.js & npm
• bufbuild (only if changing protobuf files)
• protoc (only if changing protobuf files)

To ensure interoperability with nim-waku, some tests are run against a nim-waku node. This is why nim-waku is present as a git submodule, which itself contain several submodules. At this stage, it is not possible to exclude nim-waku tests, hence git submodule update --init --recursive is run before testing (see pretest script).

To build nim-waku, you also need Rust.

Guidelines

• Please follow Chris Beam's commit message guide,
• Usually best to test new code,
• CI must pass.
