Part 4 - BotApp.d - a built-in DataStore#

This is a small bit preparation for the next section (Command Groups & Subcommands).

In our bot.py file, we’ll need to add some “listeners”.

Just above import dotenv add:

import aiohttp

Then, just after bot.load_extensions_from("./extensions/"), add:

1@bot.listen()
2async def on_starting(_: hikari.StartingEvent) -> None:
3    bot.d.client_session = aiohttp.ClientSession()
4
5@bot.listen()
6async def on_stopping(_: hikari.StoppingEvent) -> None:
7    await bot.d.client_session.close()

  • This creates 2 event listeners, one for when the bot is starting, and one for when the bot is stopping

  • When the bot is starting, it creates a new instance of aiohttp.ClientSession and stores it under client_session in the bot.d data store

  • When the bot is stopping, it closes the client session
