context-chatbot v1.0.2

Context For Chat Bot

Simplify your code for chatbot without headache.

⚠️Breaking change⚠️

version 0.1.7 and above no longer use context variable, if you want update version from 0.1.6 and below, please check variable naming

Installation

Copy this code to your command line.

npm i context-chatbot

and add this code to your project.

import { Ctx }  from "context-chatbot";

Quick Start

• first, register context to module.

Ctx.registerContext('welcome', (id, payload)=>{
    console.log('hello ' + id)
    console.log(payload)
})

or register from array.

Ctx.registerArrayContext([
    {
        state: 'welcome',
        callback: (id, payload)=>{
            console.log('welcome' + id)
            console.log(payload)
        }
    }
])

• then, set state for id (person/number/etc).

Ctx.setState('6281955551111', 'welcome')

• finally, put this line code to your bot file.

Ctx.Context('6281955551111', 'this is payload')
// output:
// 'welcome 6281955551111'
// 'this is payload'

Context with timer

This function allow you to restricted response from user (time out), if the time is up, then the state will change to the desired state

Ctx.registerArrayContext([
    {
        state: 'welcome',
        callback: (id, payload, timeOut)=>{
            console.log('welcome' + id)
            console.log(payload)
            //Dont forget to clear timeout
            clearTimeOut(timeOut)
        }
    }
])

//if there is no input for 5 seconds, state will change from 'welcome' to 'base'
Ctx.setState(id, "welcome", 5000, "base");

Using middleware

if you dont know where to place setState function to change state, maybe this can help you

Ctx.setMiddleware((id, payload, next) => {
	if (payload.message.includes("!login")) {
		Ctx.setState(id, "login_ask_username");
	}
	next();
});
