popn-db-js

A JavaScript/TypeScript client for querying pop'n music SQLite databases (popn-dbs). The current version is 0.21.1. It provides typed access to chart data for supported datecode versions including Unilab (2024073100), Jam&Fizz (2025092400 with extras), and High Cheers (202605___). Key differentiators: strongly-typed API aligned with specific game versions, supports both ESM imports and CJS require, and offers query filtering (e.g., by folder, level).
