HOWTO: Working with @quatrain/api

The @quatrain/api package contains shared types and base classes for all API-related logic in the Quatrain framework.

1. Defining the API Payload

When defining custom responses or interacting with data across the network, use the ApiPayload interface:

import { ApiPayload } from '@quatrain/api';
 
const myPayload: ApiPayload = {
   data: [
      { uid: '123', name: 'Test' }
   ],
   meta: {
      count: 1,
      offset: 0,
      batch: 10
   }
};

2. Using Endpoint Signatures

If you are building custom Server Adapters (for Express, Fastify, etc.), you should leverage the ServerAdapter and EndpointHandler interfaces to ensure consistency across the framework.
