Basic Caching

This feature allows you to set up basic caching in your NestJS application. You can configure the time-to-live (ttl) and the maximum number of items in the cache.

const { CacheModule } = require('@nestjs/cache-manager');
const { Module } = require('@nestjs/common');

@Module({
  imports: [
    CacheModule.register({
      ttl: 5, // seconds
      max: 10, // maximum number of items in cache
    }),
  ],
})
export class AppModule {}

Using Cache Interceptors

This feature demonstrates how to use cache interceptors to automatically cache the response of a controller method. This can be useful for reducing the load on your server by caching frequently requested data.

const { CacheInterceptor, CacheModule } = require('@nestjs/cache-manager');
const { Controller, Get, UseInterceptors } = require('@nestjs/common');

@Controller('cats')
@UseInterceptors(CacheInterceptor)
export class CatsController {
  @Get()
  findAll() {
    return [{ name: 'Tom' }, { name: 'Jerry' }];
  }
}

Custom Cache Store

This feature allows you to use a custom cache store, such as Redis, for your caching needs. This can be useful for distributed caching scenarios where you need a more robust and scalable caching solution.

const { CacheModule } = require('@nestjs/cache-manager');
const { Module } = require('@nestjs/common');
const * as redisStore from 'cache-manager-redis-store';

@Module({
  imports: [
    CacheModule.register({
      store: redisStore,
      host: 'localhost',
      port: 6379,
    }),
  ],
})
export class AppModule {}
