npm version Build Status


Imagine you are creating a chatbot and you want to create a way for your users to create dynamic responses for messages. Like being able to get the current title on the platform or even getting the current time in the streamers timezone. This can be a complex problem to solve but this module is here to help!

This is BMP or "BeepBot Message Parser" it allows you to give an input string which could contain args/methods which get converted to methods and new values replace them. Pretty neat huh?


import  { Parser } from 'beepbot-message-parser';

const testVars: { [name: string]: number } = {
    cheese: 1,
    test: 2,
const parser = new Parser({
    varCallback: async (coreId: string, varName: string, type: VarType) => {
        const val = testVars[varName.toLowerCase()];
        if (testVars[varName.toLowerCase()] === undefined) {
            return 1;
        switch (type) {
            case 'incr':
                return val + 1;
            case 'decr':
                return val - 1;
                return val;

async function run(channelMessage: IMessage, channelSettings: any, input: string) {
    return await parser.parse(channelMessage: IMessage, channelSettings: any, input: string);

run(channelMessage, channelSettings, input)
    .then(res => console.log(res))
    .catch(err => console.error(err));
