Quick Start

Run the TypeSpec compiler to emit OpenAPI, JSON Schema, and Protobuf outputs for your project.

Frequently Asked Questions about typespec-emitters

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I emit TypeSpec to OpenAPI and JSON Schema simultaneously?▼

To emit TypeSpec to OpenAPI and JSON Schema, you run the TypeSpec compiler with deterministic emitter configurations to coordinate multiple output formats across REST and validation workflows.

Can I generate Protobuf field mappings from a TypeSpec model?▼

Yes, you can generate Protobuf field mappings from a TypeSpec model by applying the Protobuf emitter to translate your data contracts into Protobuf format.

What is the best way to configure multiple emitters in a TypeSpec project?▼

The best way to configure multiple emitters in a TypeSpec project is applying deterministic emitter configuration to coordinate OpenAPI, JSON Schema, and Protobuf outputs across data contracts.

Do I need custom emitters to output validation schemas from TypeSpec?▼

You do not need custom emitters for validation schemas because the JSON Schema emitter handles them, but custom emitters are supported via TypeSpec tooling for specialized formats.

Does TypeSpec support version control when emitting OpenAPI specifications?▼

Yes, TypeSpec supports version control when emitting OpenAPI specifications through the OpenAPI emitter's version control and output options.

Why use TypeSpec emitters instead of maintaining separate API specifications?▼

TypeSpec emitters streamline API and data-validation workflows by generating multi-format specifications from a single model, eliminating the need to maintain separate OpenAPI, JSON Schema, and Protobuf files.
