What it does

Unifies chat bot development across multiple platforms, including Slack, Microsoft Teams, Google Chat, and Discord, using a single TypeScript SDK.

When to use it

•You're building a chat bot that needs to work seamlessly across multiple platforms.
•You want to simplify your chat bot development process by using a single SDK for all platforms.
•You're looking for a scalable solution to manage multiple chat bots across different platforms.

Ready-to-paste prompt

const chat = new Chat({ platform: 'slack', token: 'YOUR_SLACK_TOKEN' }); chat.send('Hello, world!');

Heads up: You need to replace `YOUR_SLACK_TOKEN` with a valid Slack bot token, which requires creating a Slack app and configuring the necessary permissions and credentials.
