Satanic NPM | npm.io

Getting started

Satanic.JS is a Node.JS module, that provides convenient functions, that make coding easier and Telegraf wrapper

P.S. There will be no conflicts with native methods in new methods of global classes - if one of them already exists, it will not be replaced by a new one

Installation

npm i satanic

or using yarn:

yarn add satanic

Usage

import tools from 'satanic'

API

Realtime work with JSON

data/file.json (example):

{
    "key 1": "value",
    "key 2": "value 1",
    "key 3": 100
}

Create instance

const path = 'data/file.json'
const file = new tools.JSONFile(path)

toObject()

Convert file data to object

await file.toObject() // {"key 1": "value","key 2": "value 1","key 3": 100}

get(path)

Get value by key from json file

await file.get('key 2') // 'value 1'

set(path, value)

Set value by key in json file

await file.set('key 2', 'new value') // 'new value'

add(path, value)

Add value to existing value by key in json file

await file.get('key 2') // 'value 1'
await file.add('key 2', ', 2')
await file.get('key 2') // 'value 1, 2'

includes(key)

Check if json file includes key

await file.includes('key 3') // true
await file.includes('key 2') // false

Tools

const logQueue = new Queue(data => console.log(data))
logQueue.addTask('Some data to log')

random(min, max, decimal)

Returns random entities

tools.random(10) // random integer between 0 and 10
tools.random(10, 100) // random integer between 10 and 100

log(data, silent, error)

Write logs to logs.txt and log data to console Use silent = true to log without sending data to console Use error = true to log data like error

tools.log('Debug data', true)
tools.log('Error', false, true)
tools.log(['Array', 'of', 'data'])

readEnv(path)

    key: 'value'
}, 'data/file.json')

getJSON(path)

Get JSON from local file

tools.saveJSON({ key: 'value' }, 'data/file.json')
const data = tools.getJSON('data/file.json')
console.log(data) // { "key": "value" }

getDate(cron)

Returns Date object by cron

const cron = '* */2 * *'
const date = tools.getDate(cron)
console.log(date instanceof Date) // true

randomBoolean()

tools.randomWithChance({
    'key 1': 30, // key: percent of chance
    'key 2': 50,
    'key 3': 20
})

doAtDate(date)

Run code at date (also supports cron time)

tools.doAtDate(new Date(1595425476085), () => {
    console.log('Now is Wed Jul 22 2020 16:44:36')
})
tools.doAtDate('*/1 * * * *', () => {
    console.log('Console log every minute')
})

sleep(ms)

Async sleep

console.log('Log now')
tools.sleep(1000)
console.log('Log after a second')

repeat(count, callback)

Repeat callback function count times

tools.repeat(4, i => console.log(i))
// 0
// 1
// 2
// 3

forObject(object, callback)

Iterate over object

const animalsSounds = {
    cat: 'Meow',

forObject(animalsSounds, (animal, sound) => {
    if (sound === null) {
        return 'continue'
    }
    console.log(`${animal} says ${sound}!`)
})

U can return continue or break from callback function to go to next iteration immediately or stop cycle.
