BabelFHIR-TSFHIR to TypeScript, done right

Generate profile-aware TypeScript interfaces, validators, and a type-safe FHIR client from any Implementation Guide.

🔒

Strongly Typed Interfaces

Profile constraints merged with base FHIR types from @types/fhir — your IDE catches errors before runtime.

✅

FHIRPath expressions from StructureDefinitions compiled into validate() methods — no external validator needed for basic checks.

🌐

Generated client extends the version-matched base client (R4/R4B/R5) with profile-specific methods and SMART on FHIR auth.

📦

Use babelfhir-ts install to add any Implementation Guide directly to your project as a dependency.

🎲

Generated .random() methods produce test resources that satisfy TypeScript types and basic cardinality.

⚡

Minimal runtime deps — only fhirpath is required for validators. Generated packages ship compiled JS + .d.ts.

🛡️

Optional Zod schemas for runtime type validation with choice type expansion, refinements, and constraint tracking.

🏥

Generate typed DICOMweb helpers that bridge FHIR ImagingStudy profiles with PACS viewers and Cornerstone3D.

🌍

Generate localized display strings for ValueSet codes using terminology server translations.

📋

Typed code unions, validation helpers, random pickers, and a central registry for all resolved ValueSets.
