FastBackendv0.1.0

Adding FastBackend to an Existing Project

  1. Install packages:

    pip install fastbackend-fastapi
npm install -g @fastbackend/cli

  2. Create fastbackend.yaml pointing to your existing schema file.

  3. Create app/custom/ and move existing custom routes there.

  4. Replace manual CRUD routes with the runtime:

    from fastbackend_fastapi import create_app
app = create_app()

  5. Run fastbackend generate to produce IR and OpenAPI.

  6. Remove hand-written CRUD route files that duplicate runtime behavior.

Before vs After

Before After
Hand-written CRUD routers Runtime creates routes from IR
Manual Pydantic schemas Runtime creates models from IR
Manual OpenAPI annotations Core generates OpenAPI from IR
Business logic endpoints Keep in app/custom/

Keep: schema definitions, custom business logic, database migrations, auth middleware.
