How to sort imports like a pro in TypeScript

Crossing reviews becomes a very common activity today in engineering behavior. To help us review changes for pull/merge requests easier, sorting imports can help us a much. The codebase becomes more professional and more consistent, reviewers will be happier, and the review process will be faster, focusing on the implementation changes ONLY.

Have you ever thought about how to sort imports in TypeScript projects automatically?

Let me show you how to archive sorting imports automatically in TypeScript projects with ESLint!

First of all you make a bot whose multiple instances are to be run from the same server.

Suppose the bot is run by invoking main.py with the bot_name and token as command line arguments.

Syntax:

[PYTHON] [ENTRY_POINT] [bot_name] [token]

Example:

python main.py mysamplebot "173453434:42jhs894_13234jsjgasjs"

Here is an example of .env file you need to use:

Make sure to have telethon and python-dotenv installed.

aahnik

import asyncio
from settings import API_ID, API_HASH
from telethon import TelegramClient
from utils import _


async def get_chat_id(ref=None):
    async with TelegramClient('tg_session', API_ID, API_HASH) as client:
        if not ref:
            ref = input('Enter link/phone/username/id to get chat info: ')

How to run

1. Install dependancies.

pip3 install python-dotenv python-telegram-bot

2. Then put the files of this gist inside a folder.
