## 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/

To run a development version locally, do:

```shell
git clone https://github.com/status-im/js-waku/ ; cd js-waku
npm install   # Install dependencies for js-waku
npm run build # Build js-waku
cd web-chat   
npm install   # Install dependencies for the web app
npm run start # Start development server to serve the web app on http://localhost:3000/js-waku
```

Use `/help` to see the available commands.

## 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](https://github.com/status-im/nim-waku/blob/master/examples/v2/chat2.nim).
To run the chat app, first ensure you have [Node.js](https://nodejs.org/en/) v14 or above:

```shell
node --version
```

Then, install and run:

```shell
git clone https://github.com/status-im/js-waku/ ; cd js-waku
npm install   # Install dependencies for js-waku
npm run build # Build js-waku
cd examples/cli-chat
npm install # Install dependencies for the cli app
npm run start -- --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.
