Example usage

This example will show you how to connect to the SwitchCraft Chatbox API with a basic Hello World bot.

1. Obtain a Chatbox token by running /chatbox license in-game. You can click the token to copy it to your clipboard.
2. Set up your project with npm init, and install SwitchChat by running npm i switchchat.
   • To make sure ESM modules are used, open package.json and set "type": "module".
3. Create a file called index.js with the following code:

// Import SwitchChat
import {Client} from "switchchat";

// Create the Chatbox client
const sc = new Client("YOUR-CHATBOX-TOKEN", {
    // Optional - set the default name and markdown formatting mode for all `.say()` and `.tell()` calls
    defaultName: "Hello World Bot",
    defaultFormattingMode: "markdown",
});


// Add event listener for when a backslash command is received
sc.on("command", async (cmd) => {
    // Only respond if the command is `\helloworld`
    if (cmd.command === "helloworld") {
        // Send message back to the user: "Hello World!"
        await sc.tell(cmd.user.name, "Hello World!");
    }
});

// Event listener for when the client is connected to SwitchCraft and ready to
// receive messages and events
sc.on("ready", () => {
    console.log("Connected!");
});

// Connect to SwitchCraft
sc.connect();

4. Run your code! If you used JavaScript you can run it with node index.js. When it says "Connected!", run \helloworld in-game, and the Chatbox should respond to you!

Events

You are able to listen after the following events, which directly map to the events sent by the Chatbox websocket API:

• user - User that ran the chatbox command
• command - The name of the command (the word immediately following the backslash/caret/pipe, excluding the backslash/caret/pipe). Example: \command arg1 arg2
• args - Array of space-separated string arguments after the command.
• ownerOnly - boolean if the command is an owner-only command (^command)

Join

Server restart scheduled

(Websocket API docs – API reference)

The event received when a server restart has been scheduled. At the time of restartAt, the server will restart and the SwitchChat client will be disconnected.

If a server restart was scheduled before the websocket connected, then the server_restart_scheduled event will be sent after the hello/ready events. In this case, restartSeconds will not be the time until the restart, but instead the time that was initially specified for the restart. time will still be the initial time the restart was scheduled, and restartAt will be the time the restart will happen.

• restartType - string that tells you what type of restart it is ("automatic" or "manual")
• restartSeconds - number that tells you how many seconds until the restart
• restartAt - Date that tells you when the restart will happen

Server restart cancelled

(Websocket API docs – API reference)

The event received when a previously scheduled server restart has now been cancelled.

• restartType - string that tells you what type of restart it was ("automatic" or "manual")

Rate limits

(Websocket API docs)

The Chatbox server has a ratelimit of 500ms per license, with up to 5 messages queued at once.

When the methods client.say and client.tell are called, the data is enqueued internally before being sent to the server.

This internal queue makes it safe to go well over the limits, because it processes each message every 500ms to avoid hitting the rate limit of the server.

Server -> Client packets

You are also able to listen after these packets that are sent by SwitchCraft to the client.
