## This is a Work In Progress
You can track progress on the [project board ](https://github.com/status-im/js-waku/projects/1 ).
## Examples
## Chat app
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:
```shell
npm install
2021-04-01 04:46:14 +00:00
npm run chat:app -- --staticNode /ip4/134.209.139.210/tcp/30303/p2p/16Uiu2HAmPLe7Mzm8TsYUubgCAW1aJoeFScxrLj8ppHFivPo97bUZ
2021-04-01 00:09:51 +00:00
```
2021-04-01 04:46:14 +00:00
You can also specify an optional `listenAddr` parameter (.e.g `--listenAddr /ip4/0.0.0.0/tcp/55123` ).
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.

## Contributing
To build and test this repository, you need:
- [Node.js & npm ](https://nodejs.org/en/ )
- [bufbuild ](https://github.com/bufbuild/buf )
- [protoc ](https://grpc.io/docs/protoc-installation/ )
To ensure interoperability with [nim-waku ](https://github.com/status-im/nim-waku/ ), some tests are run against a nim-waku node.
This is why `nim-waku` is present as a [git submodule ](https://git-scm.com/book/en/v2/Git-Tools-Submodules ), 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 ](https://github.com/status-im/js-waku/blob/main/package.json )).
To build nim-waku, you also need [Rust ](https://www.rust-lang.org/tools/install ).
