OSRS .json Hiscores

OSRS .json Hiscores is a server-side API wrapper designed to transform Old School RuneScape hiscores data into structured and developer-friendly JSON objects, addressing limitations in the official API’s output formats. The official API typically returns CSV or basic arrays, which can be difficult to work with, so this project restructures the data into meaningful objects that include player stats, rankings, and inferred metadata. It also adds additional logic to determine player game modes, including historical transitions such as de-ironing or hardcore status changes. The library includes functions for retrieving leaderboard pages, skill rankings, and activity statistics, making it suitable for building analytics dashboards or game-related applications. It supports TypeScript with full type definitions, improving developer experience and reliability when integrating into backend systems.
