SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a standardized pattern for creating and deploying serverless API endpoints on Vercel using TypeScript, with built-in support for kvCache, rate limiting, CORS, error handling, and vercel.json registration.

Core Features & Use Cases

  • Endpoint scaffolding: generate api/<namespace>/<action>.ts files following the project's conventions.
  • State management & security: integrate kvCache, implement rate limiting and CORS, and provide robust error handling.
  • Use Case: Add a new API route to expose a backend function for NuxChain's frontend and services.

Quick Start

Add a new endpoint by creating api/<namespace>/<action>.ts and register it in vercel.json, then test the route locally.

Frequently Asked Questions about vercel-api-endpoint

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

FAQPage Schema
How do I create a Vercel serverless API endpoint with TypeScript?▼

To create a Vercel serverless API endpoint, you scaffold a TypeScript file at api/<namespace>/<action>.ts, implement the handler with CORS and error handling, and register the route in vercel.json.

How do I add kvCache and rate limiting to a Vercel serverless function?▼

You can add kvCache and rate limiting to a Vercel serverless function by applying standardized TypeScript patterns that integrate Vercel KV cache for state management and secure endpoints against abuse.

What is the correct file placement for Vercel API routes in a TypeScript project?▼

The correct file placement for Vercel API routes is the api/<namespace>/<action>.ts directory structure, which organizes backend handlers logically while ensuring proper vercel.json registration.

Do I need to manually configure OPTIONS handling for CORS in Vercel endpoints?▼

No, you do not need to manually configure OPTIONS handling for CORS entirely from scratch, as the endpoint scaffolding pattern applies standardized OPTIONS handling and robust error responses automatically.

Why register serverless endpoints in vercel.json when using TypeScript API routes?▼

Registering serverless endpoints in vercel.json is necessary to expose the backend handlers correctly for deployment, ensuring the project's routing conventions map to the generated api/<namespace>/<action>.ts files.
