hikari

library2.5.0pypypi✓ verified 84d ago

Hikari is an asyncio-native Discord API wrapper for Python 3.10+ (Python 3.14 compatible via <3.15 constraint). As of v2.5.0, it provides both REST and gateway (WebSocket) APIs with a model-first design. The library replaces the older lightbulb command framework with first-class interaction support. Breaking changes between 2.x minor versions mainly involve gateway event handling and model attribute casing.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

RESTApp

✓ from hikari import RESTApp

✗ from hikari.impl import RESTApp

Top-level exports changed in v2; the legacy impl submodule is still available but not recommended.

GatewayBot

✓ from hikari import GatewayBot

✗ from hikari.impl import GatewayBot

Same as RESTApp, prefer top-level.

Intents

✓ from hikari import Intents

Bitwise intents enum merged into top-level in v2.

events

✓ import hikari.events as events

Events are accessed via the hikari.events module.

Simple bot that responds to !ping with Pong! using GatewayBot.

import asyncio import os import hikari bot = hikari.GatewayBot(token=os.environ.get('DISCORD_TOKEN', '')) @bot.listen() async def on_message(event: hikari.events.MessageCreateEvent) -> None: if event.content and event.content.startswith('!ping'): await event.message.respond('Pong!') if __name__ == '__main__': bot.run()

Debug

Known issues

breakingGatewayBot.listen() no longer accepts a lambda as the event handler in v2.5. Use an async function or a callable class.

fix

Use an async function or a callable class that can be awaited.

affects: >=2.5.0

breakingCache configuration has changed in v2.5.0: the cache is now passed via the 'cache' parameter of GatewayBot or RESTBot, not via a separate component.

fix

Move cache configuration from a cache component to the GatewayBot constructor, e.g., bot = GatewayBot(token=..., cache=hikari.CacheSettings(...)).

affects: >=2.5.0

deprecatedhikari.Message.mention field is deprecated, use hikari.Message.user_mentions or hikari.Message.role_mention_ids.

fix

Replace .mention with .user_mentions for user mentions or .role_mention_ids for role mentions.

affects: >=2.5.0

gotchaRESTBot and GatewayBot require aiohttp session management; do not create multiple sessions without closing previous ones (resource leak).

fix

Use the bot as a context manager (async with bot:) or call bot.close() on shutdown.

affects: all

Errors

Common errors & fixes

ImportError: cannot import name 'GatewayBot' from 'hikari'

Attempting to import from 'hikari' directly in an older version where the classes were in 'hikari.impl'.

fix

Ensure you have hikari>=2.0.0 installed: pip install hikari --upgrade

TypeError: object NoneType can't be used in 'await' expression (attempting to use lambda)

Passing a lambda as event handler to bot.listen() in hikari>=2.5.0, which requires a coroutine function.

fix

Replace the lambda with an async function.
