Node.js & Typescript OKX (OKEX) API SDK

Node.js connector for the OKX APIs and WebSockets:

• Complete integration with all OKX APIs.
• WebSocket support coming soon.
• TypeScript support (with type declarations for most API requests & responses).
• Over 100 end-to-end tests making real API calls & WebSocket connections, validating any changes before they reach npm.
• Coming soon: robust WebSocket integration with configurable connection heartbeats & automatic reconnect then resubscribe workflows.
• Browser support (via webpack bundle - see "Browser Usage" below).

Beta Release

• REST APIs are fully integrated with end to end test coverage
• WebSocket support is coming soon.

Documentation

Most methods accept JS objects. These can be populated using parameters specified by okx's API documentation, or check the type definition in the rest-client class methods.

• RestClient.
• OKX API Documentation.

Structure

This project uses typescript. Resources are stored in 3 key structures:

• src - the whole connector written in typescript
• lib - the javascript version of the project (compiled from typescript). This should not be edited directly, as it will be overwritten with each release. This is also the version published to npm.
• dist - the packed bundle of the project for use in browser environments (manual, using webpack).
• examples - some implementation examples & demonstrations. Contributions are welcome!

Usage

Create API credentials at okx

• OKX my-api

REST Client

Requests & Responses

• If your IDE doesn't have IntelliSense, check the rest-client.ts for a list of methods, params & return types.
• Requests follow the same ordering and format as the categories in the API docs.
• Responses are parsed automatically for less nesting. Error responses are thrown in full:
  • If the response looks successful (HTTP 200 and "code" in the response body === "0"), only the data property is directly (without the code, data & msg properties).
  • If the response looks like an error (HTTP error OR the "code" property in the response does not equal "0"), the full response is thrown (including code and msg properties). See the interface for APIResponse.

Browser Usage

Build a bundle using webpack:

• npm install
• npm build
• npm pack

The bundle can be found in dist/. Altough usage should be largely consistent, smaller differences will exist. Documentation is still TODO.
