by danfry·Mar 13, 2026·1 point·0 comments
AI Analysis
●●SolidSlickSolve My Problem
Replaces eval() with typed sandboxing while JEXL and jsonata already exist.
Strengths
- •Pipe operator enables readable transform chains like trim |> upper in expressions.
- •Zero runtime dependencies with ESM-only packaging for clean TypeScript integration.
- •Depth and timeout guards prevent infinite loops in untrusted user-authored expressions.
Weaknesses
- •Expression evaluator category already has JEXL, jsonata, and Google CEL established.
- •No visual expression builder for non-technical admins to create rules safely.
