Practical overview

When it fits

Use it when building software that needs a JavaScript or TypeScript connection to Bybit’s REST or WebSocket APIs, rather than when seeking a ready-made trading dashboard.

Who it is for

  • Developers building Node.js applications that need Bybit API access.
  • JavaScript or TypeScript developers integrating Bybit data, WebSocket events or trading-related API requests.
  • Frontend developers who want to use the SDK in a browser project and can configure its documented browser prerequisites.

Documented uses

  • Retrieve Bybit data through REST clients.
  • Subscribe to WebSocket event streams for market or account-related application workflows.
  • Send WebSocket API requests and handle results through promises or response and error events.
  • Add Bybit account or trading operations to custom software.
Before you choose

Requirements & limits

The SDK is available as a public GitHub repository specifying an MIT license; installation is documented through npm.

  • It supports both REST and WebSocket interfaces, including WebSocket API requests.
  • JavaScript is supported without TypeScript, although the documentation recommends TypeScript.
  • Browser integration requires additional setup; the README documents stream-browserify, a TypeScript path mapping and a global declaration.
  • REST examples require Bybit API credentials; the README also shows testnet and demo-trading configuration options.
  • The README describes support for HMAC and RSA API authentication.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare a browser import

Configure the documented modern import approach for a frontend project.

Before you start

  • A frontend project using TypeScript.

Steps

  1. Install stream-browserify with npm.

  2. Add the documented stream path mapping to tsconfig.json, pointing to ./node_modules/stream-browserify.

  3. Declare window.global in the application’s global context, such as its polyfills.

Expected outcome

The documented browser-import prerequisites are configured for the frontend project.

Guide limitations

  • The documentation describes setup, not a complete browser integration or execution test.
