Contract-first API development establishes a clear API schema before coding. It streamlines API development by enabling parallel frontend and backend workflows, ensuring teams build against an agreed-upon OpenAPI or GraphQL contract.

To design a RESTful API using OpenAPI, define your schema first to generate server stubs and client SDKs. This approach allows frontend and backend teams to develop independently based on the shared API contract.

Yes, you can generate server stubs and client SDKs from GraphQL schemas. This allows small teams to enforce an API-first design approach and facilitate parallel frontend and backend development workflows.

API-first design works effectively for small startup teams. By defining the API contract first using OpenAPI or GraphQL, a startup can build a user management API while frontend and backend teams work in parallel.

The best way to start designing a blog platform API with OpenAPI is to define the schema focusing on core resources like posts and comments. This establishes the contract needed to generate stubs and enable parallel development.

You should not use a contract-first approach if your project requires rapid prototyping without a fixed schema. It enforces strict API contracts, which may slow down initial development for small teams not needing parallel workflows.
