Emittery's release frequency has varied significantly since its initial versions in late 2017. There were periods of frequent updates (e.g., late 2017, mid-2018, mid-2022) followed by extended periods of inactivity. Releases slowed down substantially starting in late 2022 through 2024. Two releases have occurred in 2025, one in January and another in June.
Emittery is a simple, fast, and lightweight asynchronous event emitter. It allows you to register listeners for specific event names and emit events with data to those listeners. It boasts excellent performance and a minimal footprint, making it ideal for real-time applications, notifications, and decoupling components. Emittery supports synchronous and asynchronous listeners, wildcards, and event filtering, all within a concise and easy-to-use API. Its TypeScript support ensures type safety and a smooth developer experience.
Emittery's npm downloads show strong growth throughout 2024 and 2025. Downloads steadily increased, peaking in June 2025 at over 163 million. While August 2025 saw a slight dip, September 2025 downloads are significantly lower, reflecting an incomplete month of data.
