How To Use Redis As A Store For Session In NestJS 2023

To use Redis for storing sessions in a NestJS application, you will first need to install the @nestjs/session and connect-redis packages as dependencies:

npm install @nestjs/session connect-redis

Once these packages are installed, you can use the SessionModule from @nestjs/session to configure your NestJS application to use Redis for storing sessions.

Here's an example of how you might set up the SessionModule with Redis:

import { Module } from '@nestjs/common';
import { SessionModule } from '@nestjs/session';
import { RedisModule } from 'nestjs-redis';

@Module({
  imports: [
    RedisModule.forRoot({
      host: 'localhost',
      port: 6379,
    }),
    SessionModule.forRoot({
      store: {
        type: 'redis',
      },
    }),
  ],
})
export class AppModule {}

This will configure the SessionModule to use Redis for storing sessions, using the default Redis connection specified in the RedisModule.

You can then use the @Session decorator from @nestjs/session to access the session data in your controllers or services.

For example:

import { Controller, Get, Session } from '@nestjs/common';

@Controller('users')
export class UserController {
  @Get()
  findAll(@Session() session) {
    console.log(session);
    // Access the session data here
  }
}
