tmi js is a program package for Windows that gives you the ability to connect and interact with Twitch chat using Node js or a web browser. It is necessary to point out that you can control the delay between requests in milliseconds, automatically join channels, reconnect and more.

Purpose

If you have spent some time watching Twitch streams, you may have noticed users with the bot in their name posting messages that could be anything from advertisements to custom commands. Essentially, these are servers hosted somewhere on the Internet capable of listening to the chat, making appropriate replies, promoting products, and more. In order to create bots, you need to have appropriate development tools and libraries, including tmi js.

Functionality

Starting off, the name of the distribution stands for Twitch Messaging Interface. When it comes to the main function, it does exactly what it sounds like, since it provides you with an advanced mechanism for interacting with the Twitch messaging system. The main goal of this library is to give you the means to programmatically listen to chat events, and perform certain actions when they do occur. Alternatively, you may use ready-made software solutions like AnkhBot.
