@nestjs-yalc/api-strategy

Transport strategy helpers for keeping application code stable while the underlying call path changes.

Use this package to code against HTTP call or event interfaces while selecting local Nest calls, remote HTTP calls, emitted events, fallback chains, shadow calls, or conditional strategies through providers.

Installation

npm install @nestjs-yalc/api-strategy

Main Exports

• NestLocalCallStrategy for in-process Nest/Fastify calls.
• NestHttpCallStrategy and HttpAbstractCallStrategy for remote HTTP calls.
• NestLocalEventStrategy and RabbitMqEventStrategy for event emission.
• FallbackCallStrategy, ShadowCallStrategy, and conditional/composite strategies for staged migrations and resilience.
• ContextCallServiceFactory, ContextEventServiceFactory, and strategy selector providers for Nest DI wiring.

Example

import { NestHttpCallStrategy } from '@nestjs-yalc/api-strategy';

const usersApi = new NestHttpCallStrategy(httpService, UserDto, baseUrl);
const users = await usersApi.get('/users');
