RxJS Rate Limiter (mostly lossless)

• RxJS 7 pipeline operator
• Dead simple (40 lines)
• No dependencies
• Processes immediately, no delay to emissions

Beware

• No retries, that's up to you
• Currently only packaged for CommonJS. Open an issue if you'd like to consume an ESM.

Installation

npm add @curiouser/rxjs-rate-limit

Usage

const rateLimit = require('@curiouser/rxjs-rate-limit');

// 20 per second
someObservable.pipe(
  rateLimit(20, 1000),
  // do something that should be rate limited
);
