@thermopylae/core.cookie-session v1.0.1

Cookie user session for HTTP interface.

Install

npm install @thermopylae/core.cookie-session

Description

This package contains Http Middleware for cookie user session management. It uses @thermopylae/lib.user-session for session management and contains implementation for repositories required by the library.

Usage

import { LoggerManagerInstance, OutputFormat } from '@thermopylae/core.logger';
import { ConnectionType, initLogger as initRedisClientLogger, RedisClientInstance, RedisConnectionOptions } from '@thermopylae/core.redis';
