# websocket-server
This benchmarks a websocket server intended as a simple but very active chat room.
First, start the server. By default, it will wait for 16 clients which the client script will handle.
Run in Bun (`Bun.serve`):
```bash
bun ./chat-server.bun.js
```
Run in Node (`"ws"` package):
```bash
node ./chat-server.node.mjs
```
Run in Deno (`Deno.serve`):
```bash
deno run -A --unstable ./chat-server.deno.mjs
```
Then, run the client script. By default, it will connect 16 clients. This client script can run in Bun, Node, or Deno
```bash
node ./chat-client.mjs
```
The client script loops through a list of messages for each connected client and sends a message.
For example, when the client sends `"foo"`, the server sends back `"John: foo"` so that all members of the chatroom receive the message.
The client script waits until it receives all the messages for each client before sending the next batch of messages.
TODO: once Deno lands their performance improvements, increase the client count (it was originally going to be 32 or 64, but that would've exluded Deno from the benchmark)
This project was created using `bun init` in bun v0.2.1. [Bun](https://bun.sh) is a fast all-in-one JavaScript runtime.
