## What it is
tmi.js is a JavaScript library for connecting to and interacting with Twitch chat (IRC) from Node.js or the browser. It provides a client for reading messages, sending chat commands, and building Twitch bots and chat overlays.

## Use cases
- build a twitch chat bot
- connect to twitch chat from nodejs
- create a chat overlay for obs
- handle twitch chat commands like !hello
- read twitch chat messages anonymously
- send messages to twitch chat with a bot account

## When to choose
- you need a battle-tested JavaScript client for Twitch chat IRC
- you want to build Twitch bots or chat overlays in Node.js or the browser
- you want a simple event-based API for reading and sending chat messages

## When to avoid
- you need Twitch API features beyond chat (the IRC connection lost some commands in 2023)
- you are building bots for platforms other than Twitch
- you need a fully supported long-term solution without awareness of the planned v2 rewrite
