Nestjs|Nestjs 缓存 Nestjs缓存

Docs: https://docs.nestjs.com/techniques/caching

yarn add @nestjs/mongoose mongoose
yarn add cache-manager

app.module.ts

import { Module, CacheModule } from '@nestjs/common'; import { AppController } from './app.controller'; import { AppService } from './app.service'; import { MongooseModule } from '@nestjs/mongoose' import { CatSchema } from './schemas/cat.schema'@Module({ imports: [ CacheModule.register({ ttl: 5, // 缓存更新时间 max: 10 }), MongooseModule.forRoot('mongodb://localhost/ajanuw', { useNewUrlParser: true }), MongooseModule.forFeature([ { name: 'cats', schema: CatSchema } ]) ], controllers: [AppController], providers: [AppService], }) export class AppModule {}

cat.schema.ts

import * as mongoose from 'mongoose'; export const CatSchema = new mongoose.Schema({ name: String, });

app.service.ts

import { Injectable } from '@nestjs/common'; import { Model } from 'mongoose' import { InjectModel } from '@nestjs/mongoose' import { Cat } from './interfaces/cat.interface' @Injectable() export class AppService { constructor( @InjectModel('cats') private readonly catModel: Model ){}all(): Promise{ return this.catModel.find().exec() } }

cat.interface.ts

import { Document } from 'mongoose' export interface Cat extends Document { readonly name: string; }

app.controller.ts

import { Get, Controller, UseInterceptors, CacheInterceptor } from '@nestjs/common'; import { AppService } from './app.service'; @Controller() @UseInterceptors(CacheInterceptor) export class AppController { constructor(private readonly appService: AppService) {}@Get('all') all(){ let cats = this.appService.all() return cats } }

存在 Redis当中

yarn add cache-manager-redis-store

app.module.ts

import { Module, CacheModule } from '@nestjs/common'; import { AppController } from './app.controller'; import { AppService } from './app.service'; import * as redisStore from 'cache-manager-redis-store'import { MongooseModule } from '@nestjs/mongoose' import { CatSchema } from './schemas/cat.schema'@Module({ imports: [ CacheModule.register({ store: redisStore, host: 'localhost', port: 6379, ttl: 10, // 缓存更新时间 max: 15, }), // CacheModule.register(), MongooseModule.forRoot('mongodb://localhost/ajanuw', { useNewUrlParser: true }), MongooseModule.forFeature([ { name: 'cats', schema: CatSchema } ]) ], controllers: [AppController], providers: [AppService], }) export class AppModule {}
