Installation

1. Build container 'docker build -t bot .'
2. Run 'docker compose up'

Mongo debug:

1. Run 'docker compose exec mongo_db sh' to open container CLi.
2. Run 'mongosh' to start session (?).

Then you can use different commands:

• show collections
• show tables
• db.logs.find()

logs - table name to display.

Texting

Since telegram supports html or markdown modes we can use different approaches. BTW, I prefer markdown due to compact syntax. if you want to use HTML instead change getDefaultMessageParameters(). Change the 'parse_mode' to 'HTML' formatting type.

A few simple rules for editing texting YML file:

1. Always use double quotes (Otherwise \n may not work).
2. Escape following characters (.-_*), add \ character before.
3. You can find allowed formatting on this page https://core.telegram.org/bots/api#formatting-options

Services

There a bunch of sub-services to simplify code base.

Coding Standards

Just install and configure prettier in JetBrains IDE. That's it.
