Product Status: In Development
SchemaCraft is currently under active architecture and prototyping. The features described below represent our planned specification. This tool is not yet deployed for general public use.
The Concept: Visual Contract Modeling
API contracts and data payloads often begin as messy mental models. Developers spend excessive time hand-authoring verbose JSON Schema definitions, manually typing matching TypeScript interfaces, and inventing synthetic test data to exercise their endpoints.
SchemaCraft eliminates this repetitive overhead by providing a unified, visual designer that treats data models as interactive node trees.
Planned Capabilities
- Visual Structure Design: Drag-and-drop hierarchy builder for complex nested JSON objects and arrays.
- Type Constraints & Validators: Granular constraint rules including regex patterns, numerical boundaries (min/max), string lengths, and enum definitions.
- Required vs. Optional Modeling: Toggle field optionality with visual indicators that immediately reflect in generated types.
- TypeScript Interface Generator: Live bi-directional compilation of schema nodes into clean, idiomatic TypeScript definitions.
- JSON Schema Draft 7/2020-12 Export: Standardized specification export for validation pipelines, OpenAPI docs, and form generators.
- Mock Data Synthesis: Generate realistic, customizable test payloads based on constraints and semantic field types (e.g. realistic names, UUIDs, addresses).
Architecture & Privacy Commitment
Like all Oompha Labs tooling, SchemaCraft is designed with a client-first security model:
- Local Browser Execution: Schema definitions, code generation, and mock synthesis will run completely within the browser engine without saving payloads to remote servers.
- Zero Data Telemetry: User data structures, intellectual property, and proprietary schemas remain strictly local to the developer's workstation.
