coinbase/coinbase-pro-trading-toolkit ? reverse-engineered prompt

Build me a TypeScript toolkit for Coinbase Pro trading that helps people create automated trading bots and experiment with market data in a simple way.

I want it to include the core pieces a trader would need, like connecting to the exchange, reading live price and order book updates, placing and managing orders, and showing working examples people can run right away. It should feel like a real developer library, with clear docs, sample scripts, and a few tutorial style demos that show how to use the main features end to end.

Please make it easy to install and use from Node, and include tests so the basic behavior is covered. If you need to check current exchange or library details online while building it, go ahead and look them up. Keep the code clean, practical, and focused on helping someone get from idea to a working trading bot quickly.
