creativogee/masq

Masq is a dependency-free TypeScript library for selecting and masking object fields and producing allow-listed query projections and relation joins. The main workflow is to parse a requested field mask, optionally validate it against an allow-list, then apply it to data; separate helpers turn field and relation specifications into query-builder descriptors. The runtime is contained in src/index.ts; the excerpts are partial, so links between unsampled helpers are shown only where documented.
