@orama/oramacore-events-parser

A JavaScript/TypeScript library for parsing OramaCore Server-Sent Events (SSE) streams, with a simple, strongly-typed event subscription API.

Features

• Parse SSE streams from OramaCore's /generate/answer and /generate/nlp_query endpoints
• Subscribe to specific event types with .on('event_name', handler)
• Statically-typed helpers: .onStateChange(handler) and .onProgress(handler)

Installation

npm i @orama/oramacore-events-parser

Usage

Parse Answer Stream

const emitter = parseAnswerStream(response.body!);

emitter.on('answer_token', (event) => {
  console.log('Token:', event.token);
});

emitter.onStateChange((event) => {
  console.log('State changed:', event.state, event.message);
});

emitter.onProgress((event) => {
  console.log('Progress:', event.current_step, '/', event.total_steps);
});

Parse NLP Query Stream

const emitter = parseNLPQueryStream(response.body!);

emitter.on('search_results', (event) => {
  console.log('Results:', event.results);
});

emitter.onStateChange((event) => {
  console.log('State changed:', event.state, event.message);
});

API

• .on(eventName, handler) — Subscribe to any event type
• .onStateChange(handler) — Subscribe to state_changed events (typed)
• .onProgress(handler) — Subscribe to progress events (typed)
