Worldstate Emitter

Suuuper simple emitter for worldstate events.

Very opinionated decisions on what events and event names, as well as.... everything else

Installation

npm install worldstate-emitter

This package requires Node.js 20.10.0 or higher and is an ES Module.

Peer Dependencies

You'll also need to install the following peer dependencies:

npm install warframe-worldstate-parser@^5 warframe-worldstate-data@^3

Optional Dependencies

For better logging support:

npm install winston@^3

Usage

Basic Example

import WorldstateEmitter from "worldstate-emitter";

// Create emitter instance
const emitter = await WorldstateEmitter.make({
  locale: "en",
  features: ["worldstate", "rss", "twitter"],
});

// Listen for worldstate events
emitter.on("ws:update:event", (event) => {
  console.log("New worldstate event:", event.id);
});

// Listen for RSS posts
emitter.on("rss", (post) => {
  console.log("New forum post:", post.title);
});

// Listen for tweets
emitter.on("tweet", (tweet) => {
  console.log("New tweet:", tweet.text);
});

// Get current worldstate
const worldstate = emitter.getWorldstate("en");
console.log("Current worldstate:", worldstate);

TypeScript Support

This package is written in TypeScript and includes full type definitions. All types are automatically available when using TypeScript:

import WorldstateEmitter from "worldstate-emitter";
import type WorldState from "warframe-worldstate-parser";

const emitter = await WorldstateEmitter.make({ locale: "en" });

// TypeScript will infer the correct types
const ws: WorldState | undefined = emitter.getWorldstate("en");

Configuration Options

interface WorldstateEmitterOptions {
  locale?: string; // Language to filter events (e.g., 'en', 'es', 'de')
  features?: string[]; // Features to enable: 'worldstate', 'rss', 'twitter'
}

const emitter = await WorldstateEmitter.make({
  locale: "en", // Optional: filter to English only
  features: ["worldstate", "rss"], // Optional: only enable these features
});

Environment Variables

Configure the emitter with environment variables:

• LOG_LEVEL - Logging level (default: error)
• WORLDSTATE_URL - Custom worldstate API URL
• KUVA_URL - Custom Kuva/Arbitration data URL
• SENTIENT_URL - Custom Sentient Anomaly data URL
• WORLDSTATE_CRON - Cron pattern for worldstate updates (default: 25 */5 * * * *)
• WS_EXTERNAL_CRON - Cron pattern for external data (default: 0 */10 * * * *)
• WS_EMITTER_FEATURES - Comma-separated list of features to enable
• TWITTER_KEY - Twitter API consumer key

Development

Building

This project is written in TypeScript and uses tsdown for building:

npm run build

This generates:

• dist/index.mjs - Compiled JavaScript module
• dist/index.d.mts - TypeScript type definitions

Testing

npm test

Tests use Mocha with tsx for TypeScript support.

Linting

This project uses Biome for linting and formatting:

npm run lint          # Check for issues
npm run lint:fix      # Auto-fix issues

Documentation

Generate TypeDoc documentation:

npm run build:docs
