Broid Kit

Broid Kit aims to ease the creation of bots communicating through messaging platforms. Broid Kit is powered by Broid Integrations which allows you to leverage the largest collection of messaging channels integrated in a given framework.

Connect your App to Multiple Messaging Channels with the W3C Open standards.

Quick Example

Note: Options for the integration examples can be found on the Discord, Messenger, and Slack documentation respectively.

const Bot = require("@broid/kit");
const BroidDiscord = require("@broid/discord");
const BroidMessenger = require("@broid/messenger");
const BroidSlack = require("@broid/slack");

const bot = new Bot({
  logLevel: "info",
  http: {
    host: "0.0.0.0",
    port: 8080,
  }
});

bot.use(new BroidDiscord({...options}));
bot.use(new BroidMessenger({...options}));
bot.use(new BroidSlack({...options}));

// Listening for public starting by regex match for `hello`
bot.hear("hello.*", "Group")
  .subscribe((data) => {
    console.log("Data:", JSON.stringify(data, null, 2));

    // Reply to the message
    bot.sendText("Hi, How are you?", data.message);
  });

Broid-Kit can also be used with your existing Express setup.

const Bot = require("@broid/kit");
const BroidDiscord = require("@broid/discord");
const BroidMessenger = require("@broid/messenger");
const BroidSlack = require("@broid/slack");
const express = require("express");

const bot = new Bot({
  logLevel: "info"
});

bot.use(new BroidDiscord({...options}));
bot.use(new BroidMessenger({...options}));
bot.use(new BroidSlack({...options}));

// Setup express
const app = express();
app.use("/", bot.getRouter());
app.listen(8080);

// Listening for public starting by regex match for `hello`
bot.hear("hello.*", "Group")
  .subscribe((data) => {
    console.log("Data:", JSON.stringify(data, null, 2));

    // Reply to the message
    bot.sendText("Hi, How are you?", data.message);
  });

Documentation

Receive all group messages

bot.on("Group")
  .subscribe((data) => {
    console.log("Data:", JSON.stringify(data, null, 2));

    // Reply to the message
    bot.sendText("i am listening all messages", data.message);
  });

Receive all private messages

bot.on("Person")
  .subscribe((data) => {
    console.log("Data:", JSON.stringify(data, null, 2));

    // Reply to the message
    bot.sendText("i am listening all messages", data.message);
  });

Receive all

Because Broid Kit is built with Observables, you can subscribe to multiple sources.

const Observable = require("rxjs").Observable;

Observable.merge(bot.on("Group"), bot.on("Person"))
  .subscribe((data) => {
    console.log("Data:", JSON.stringify(data, null, 2));

    // Reply to the message
    bot.sendText("i am listening all messages", data.message);
  });

Matching patterns and keywords

bot.hears(["keyword", "hello.*"], "Group")
  .subscribe(data => {
    console.log("Data:", JSON.stringify(data, null, 2));
  });

Node callback is supported

bot.hear("hello.*", "Group", (data, error) => {
  console.log("Data:", JSON.stringify(data, null, 2));
});

bot.hears(["keyword", "hello.*"], "Group", (data, error) => {
  console.log("Data:", JSON.stringify(data, null, 2));
});

Send a simple message

bot.sendText("Hello world.", data.message);

Send a video or image message

bot.sendImage("http://url-of-media", data.message, optionalMeta);

// OR

bot.sendVideo("http://url-of-media", data.message, optionalMeta);

optionalMeta is an object of optional information for the media. It should like:

{
  "content": "description of the meta",
  "title": "title for the media"
}

Middleware

Broid kit supports middleware to allow you to preprocess received or sent messages.

Example of Middleware preprocessing

class MyMiddleware {
  constructor() {}

  serviceName() {
    return "MyMiddleware";
  }

  incoming(bot, message) {
    // the return value can be an Promise<object>, Observable<object> or null
    return "Hello world!";
  }

  outgoing(bot, message) {
    // the return value can be an Promise<object>, Observable<object> or null
    // The object.content field will be use to update the text of the message sent.
    return "Good bye world!";
  }
}

This middleware can be used like so:

bot.use(new MyMiddleware());

WebHooks

Broid Kit provide an http server and creates a default webhook route when the integration requires it. By default, the webhook path follows the naming convention: webhook/<integration>, integration is the name provide by the getServiceName method.

In case of @broid/skype the webhook route will be /webhook/skype.
