Been playing with FilterQL, a tiny TypeScript query language for structured data. I like when filtering reads like plain logic. This works: (genre == Action || genre == Comedy) && rating >= 8.5 | SORT rating desc. One expression, no if-else soup.

Details I enjoy: schema defines allowed fields and aliases, logical ops () ! && ||, comparisons == != >= <= plus *= ^= $= ~= for strings and regex, boolean shorthand like monitored, and a built in SORT field asc or desc. Thoughtful and practical.

Setup is simple. Define a schema, new FilterQL({ schema }), then filter(data, query). Great for CLIs, dashboards, and APIs where users type filters. Fewer hand rolled predicates scattered around. Future me says thanks.

Small and focused with a clear language spec and a clean API. If you want user friendly filtering without going full database query language, this hits a sweet spot: https://github.com/adamhl8/filterql
