**Feels** is a Node.js library that computes various “feels‑like” temperatures—heat index, humidex, Australian apparent temperature, wind chill, and approximate wet‑bulb globe temperature—as well as related metrics such as dew point, relative humidity, and water‑vapour pressure. It provides both a class‑based API and standalone functions, making it useful for developers building weather, HVAC, or outdoor‑activity applications that need to present human‑perceived temperature values.
