About

raito-nestjs - is an Nest.js middleware and API for communicating with Raito cache server.

Getting started

[!IMPORTANT] Node.js 18.x+ version must be installed in your OS.

1. Install package

$ yarn add @raito-cache/nestjs

2. Connect to Raito

import { Module } from '@nestjs/common';
import { RaitoModule } from '@raito-cache/nestjs';

@Module({
  imports: [RaitoModule.register()],    
})
export class AppModule {}

3. Use Interceptor

import { RaitoInterceptor } from '@raito-cache/nestjs';

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @Get()
  @UseInterceptors(RaitoInterceptor)
  async getHello() {
    return await this.appService.getHello();
  }
}

API

Connect to Raito

// Async
RaitoModule.registerAsync({
  useFactory: () => ({
    port: 9180, // Raito port
    host: 'localhost', // Raito host
    ttl: 10000, // Cache records time to live  
  }),
})

// Sync
RaitoModule.register() // Connect to localhost:9180
RaitoModule.register(7180); // localhost:7180
RaitoModule.register('raito://localhost:9180'); // localhost:9180
RaitoModule.register('raito://localhost:9180?ttl=5000'); // localhost:9180 and ttl 5s
RaitoModule.register({
  port: 9180,
  host: 'localhost',
  ttl: 10000,
});

Usage

Raito Interceptor as global

import { Module } from '@nestjs/common';
import { RaitoInterceptor, RaitoModule } from '@raito-cache/nestjs';
import { APP_INTERCEPTOR } from '@nestjs/core';

@Module({
  imports: [RaitoModule.register()],  
  providers: [    
    {
      provide: APP_INTERCEPTOR,
      useClass: RaitoInterceptor,
    }
  ],
})
export class AppModule {}

Raito Interceptor as local

import { RaitoInterceptor } from '@raito-cache/nestjs';

@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @Get()
  @UseInterceptors(RaitoInterceptor)
  async getHello() {
    return await this.appService.getHello();
  }
}

Raito Service

import { Injectable } from '@nestjs/common';
import { RaitoService } from '@raito-cache/nestjs';

@Injectable()
export class AppService {
  constructor(private readonly raito: RaitoService) {}
  
  useSerive() {
    await raito.set('key', { data: 'some data' }); // Create new record 
    await raito.set('key2', 'other data', 15000); // Create new record with 15s ttl

    await raito.get('key2'); // Output: { key: 'key', data: 'other data', createdAt: Date, ttl: 15000 }
    await raito.clear('key'); // Deletes record

    await raito.shutdown(); // Close connection   
  }
}

Raito Deployment

1. Pull docker image:

$ docker pull stbestich/raito-cache:latest

2. Run it

$ docker run -e HOST=<host> -p <port>:9180 -it stbestich/raito-cache

Use with docker-compose

services:
  raito-cache:
    image: stbestich/raito-cache:latest
    ports:
      - "${PORT:-9180}:${PORT:-9180}"
      - "${PORT:-9181}:${PORT:-9181" # Define second port if you need http proxy 
    env_file:
      - .env
    environment:
      NODE_ENV: production
      PORT: ${PORT:-9180}
      HOST: ${HOST:-0.0.0.0}
      TTL: ${TTL}
    tty: true
    stdin_open: true
