Getting started

1. Get BASIS api account

To use the WhatsApp Bot API, you first have to visit basis-api.com and get free developer account for API. BASIS Api will give you id instance and api token, something like

HOST: https://en-api.basis-api.com
ID_INSTANCE: "0000",
API_TOKEN_INSTANCE: "000000000000000000AAAAAAAAAAAAAA"

In case you want API-V1 protocol you also have to visit basis-api.com and choose Chat bot price option. BASIS API will give you a free trial period if you ask them. Access token looks like this:

token = 'gr.abcdefg...'

2. Add import

You can import library using modern ES6 syntax (you have to add "type":"module" to package.json):

import WhatsAppBot from '@basisapi/whatsapp-bot'

or using classic syntax:

const WhatsAppBot = require('@basisapi/whatsapp-bot')

3. Initiliaze new WhatsApp Bot with aquired account data

For API-V0 protocol

const bot = new WhatsAppBot({
    host: https://en-api.basis-api.com
    idInstance: "0000",
    apiTokenInstance: "000000000000000000AAAAAAAAAAAAAA"
})

### 3. Start coding

A WhatsApp bot was inpired by telegram bot framework - [Telegraf](https://telegraf.js.org). But the WhatsApp bot library inherited limited part of Telegraf API. At this moment whatsapp bot can send and receive text, interact with user by telegraf scenes and use sessions. The bot supports only long-polling mode. To understand basics have look at examples below.

### Examples
Hello world example responds with a plain text phrase to any users print:

```js
const WhatsAppBot = require('@basisapi/whatsapp-bot')

const bot = new WhatsAppBot({
    host: https://en-api.basis-api.com
    idInstance: process.env.ID_INSTANCE,
    apiTokenInstance: process.env.API_TOKEN_INSTANCE
})
bot.on('message', (ctx) => ctx.reply('Hello world!'))
bot.launch()

Bot listens for users command beginning with the / symbol

const WhatsAppBot = require('@basisapi/whatsapp-bot')

const bot = new WhatsAppBot({
    idInstance: process.env.ID_INSTANCE,
    apiTokenInstance: process.env.API_TOKEN_INSTANCE
})
bot.command('oldschool', (ctx) => ctx.reply('Hello'))
bot.command('modern', ({ reply }) => reply('Yo'))
bot.command('hipster', WhatsAppBot.reply('λ'))
bot.on('message', (ctx) => ctx.reply('Send /oldschool, /modern or /hipster to launch bot'))
bot.launch()
