nestjs-cookie-session

Idiomatic Cookie Session Module for NestJS. Built on top of cookie-session 😎

This module implements a session with storing data directly in Cookie.

If you want to store data in one of external stores and passing ID of session to client via Cookie/Set-Cookie headers, you can look at nestjs-session.

Example

// app.module.ts
import { Module } from '@nestjs/common';
import {
  NestCookieSessionOptions,
  CookieSessionModule,
} from 'nestjs-cookie-session';
import { ViewsController } from './views.controller';

@Module({
  imports: [
    // sync params:

    CookieSessionModule.forRoot({
      session: { secret: 'keyboard cat' },
    }),

    // or async:

    CookieSessionModule.forRootAsync({
      imports: [ConfigModule],
      inject: [Config],
      //              TIP: to get autocomplete in return object
      //                  add `NestCookieSessionOptions` here ↓↓↓
      useFactory: async (config: Config): Promise<NestCookieSessionOptions> => {
        return {
          session: { secret: config.secret },
        };
      },
    }),
  ],
  controllers: [ViewsController],
})
export class AppModule {}

Use in controllers with NestJS built-in Session decorator:

// views.controller.ts
import { Controller, Get, Session } from '@nestjs/common';

@Controller('views')
export class ViewsController {
  @Get()
  getViews(@Session() session: { views?: number }) {
    session.views = (session.views || 0) + 1;
    return session.views;
  }
}

npm i
npm run build
cd example
npm i

API

CookieSessionModule

CookieSessionModule class has two static methods, that returns DynamicModule, that you need to import:

CookieSessionModule.forRoot for sync configuration without dependencies
CookieSessionModule.forRootAsync for sync/async configuration with dependencies

CookieSessionModule.forRoot

Accept NestCookieSessionOptions. Returns NestJS DynamicModule for import.

CookieSessionModule.forRootAsync

Accept NestCookieSessionAsyncOptions. Returns NestJS DynamicModule for import.

NestCookieSessionOptions

NestCookieSessionOptions is the interface of all options, has next properties:

session - required - cookie-session options.
forRoutes - optional - same as NestJS built-in MiddlewareConfigProxy['forRoutes'] See examples in official docs. Specify routes, that should have access to session. If forRoutes and exclude will not be set, then sessions will be set to all routes.
exclude - optional - same as NestJS built-in MiddlewareConfigProxy['exclude'] See examples in official docs. Specify routes, that should not have access to session. If forRoutes and exclude will not be set, then sessions will be set to all routes.

NestCookieSessionAsyncOptions

NestCookieSessionOptions is the interface of options to create cookie session module, that depends on other modules, has next properties:

imports - optional - modules, that cookie session module depends on. See official docs.
inject - optional - providers from imports-property modules, that will be passed as arguments to useFactory method.
useFactory - required - method, that returns NestCookieSessionOptions.
