Next Js Api Route Abstraction For Backend Service Calls

via “next-js-api-route-middleware-pattern”

OpenAI Assistants API quickstart with Next.js.

Unique: Uses Next.js API routes as a thin middleware layer that directly wraps OpenAI SDK calls, with separate routes for each operation (assistant creation, thread management, message handling, file operations) rather than a single unified endpoint

vs others: Simpler than building a custom backend because it leverages Next.js's built-in API route system, and more secure than frontend-only SDK usage because API keys are never exposed to the client

Unique: Uses Next.js API routes as a lightweight abstraction layer that supports both request-response and streaming patterns, avoiding the need for a separate API server. Middleware integration enables cross-cutting concerns (auth, logging) without polluting route handlers.

vs others: Simpler than separate Express/FastAPI servers because it leverages Next.js built-ins; more flexible than direct backend calls because the API layer can be extended with middleware without changing frontend code.
