bybit-trading-api, published on npm as bybit-api, is a Node.js, JavaScript, and TypeScript software development kit for talking to the Bybit cryptocurrency exchange. It wraps Bybit's REST API, WebSocket API, and WebSocket event streams so a developer does not have to build that connection logic themselves. The library covers all of Bybit's REST and WebSocket endpoints and is kept up to date as Bybit changes its API. It handles authentication automatically, supporting both HMAC and RSA methods, and includes TypeScript type definitions for most requests and responses so editors can catch mistakes before code runs. Plain JavaScript projects can use it too, since TypeScript is recommended but not required. On the WebSocket side, the library manages the connection for you: it sends heartbeat messages, automatically reconnects and resubscribes if a connection drops, including Bybit's scheduled daily disconnect, and emits an event when a dropped connection comes back. For the newer WebSocket API specifically, there are two ways to use it. One lets you call functions and wait for a response the way you would with a normal REST client. The other is event driven, where you send a command and then listen for response and error events from the client. According to the README, using this SDK also comes with account level benefits from Bybit directly: higher API rate limits than the site's highest VIP tier, and the ability to place orders with a smaller minimum value than Bybit's standard minimum, though the README notes this second benefit is undocumented by Bybit and could change. Installation is a single npm install command. The project is maintained by the same author as similar SDKs for other exchanges including Binance, Kraken, OKX, Coinbase, and Kucoin, and this repository is one entry point into that wider family of trading API libraries aimed at developers building trading bots, dashboards, or other automated tools on top of exchange data.
