## Examples
2021-04-27 23:53:33 +00:00
## 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 ](status-im.github.io/js-waku/ ).
It is currently unstable and likely to break.
To run a development version locally, do:
```shell
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)
2021-04-01 00:09:51 +00:00
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 ).
2021-04-23 06:33:53 +00:00
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:
2021-04-01 00:09:51 +00:00
```shell
2021-04-13 00:56:13 +00:00
git clone https://github.com/status-im/js-waku/ ; cd js-waku
2021-04-01 00:09:51 +00:00
npm install
2021-04-13 00:56:13 +00:00
npm run chat -- --staticNode /ip4/134.209.139.210/tcp/30303/p2p/16Uiu2HAmPLe7Mzm8TsYUubgCAW1aJoeFScxrLj8ppHFivPo97bUZ
2021-04-01 00:09:51 +00:00
```
2021-04-23 06:33:53 +00:00
You can also specify an optional `listenAddr` parameter (.e.g `--listenAddr /ip4/0.0.0.0/tcp/7777/ws` ).
2021-04-01 04:46:14 +00:00
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
2021-03-15 05:22:26 +00:00
To build and test this repository, you need:
- [Node.js & npm ](https://nodejs.org/en/ )
2021-04-20 00:02:47 +00:00
- [bufbuild ](https://github.com/bufbuild/buf ) (only if changing protobuf files)
- [protoc ](https://grpc.io/docs/protoc-installation/ ) (only if changing protobuf files)
2021-03-15 05:22:26 +00:00
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 ).

### Guidelines
- Please follow [Chris Beam's commit message guide ](https://chris.beams.io/posts/git-commit/ ),
- Usually best to test new code,
- [CI ](https://github.com/status-im/js-waku/blob/main/.github/workflows/ci.yml ) must pass.
