@midwayjs/express-session

Session component for @midwayjs/express

Install

$ npm i @midwayjs/express-session --save
$ npm i @types/express-session --save-dev

Usage

@midwayjs/express has enabled this component by default.

We use cookie-session to keep session by default and use express-session when set custom session store.

Config

You can configure session in your config.*.ts.

default value.

export const session = {
  secret: undefined, // must be set in application
  name: 'MW_SESS',
  cookie: {
    maxAge: 24 * 3600 * 1000, // ms
    httpOnly: true,
    // sameSite: null,
  },
};

You can set 'session.cookie' for cookie-session config.

Custom Session Store

You can use compatible session store here.

Let's give an example for memorystore.

import { Configuration, Inject } from '@midwayjs/core';
import * as session from '@midwayjs/express-session';
import MemoryStore = require('memorystore');

@Configuration({
  imports: [
    express,
    session,
  ],
  //...
})
export class AutoConfiguration {
  @Inject()
  sessionStoreManager: session.SessionStoreManager;

  async onReady() {
    this.sessionStoreManager.setSessionStore(MemoryStore, {
      checkPeriod: 86400000 // prune expired entries every 24h
    });
  }
}

Another example for connect-redis.

import { Configuration, Inject } from '@midwayjs/core';
import * as session from '@midwayjs/express-session';
import RedisStore from "connect-redis"
import {createClient} from "redis"

// Initialize client.
let redisClient = createClient()
redisClient.connect().catch(console.error)

@Configuration({
  imports: [
    express,
    session,
  ],
  //...
})
export class AutoConfiguration {
  @Inject()
  sessionStoreManager: session.SessionStoreManager;

  async onReady() {
    // Initialize store.
    this.sessionStoreManager.setSessionStore(RedisStore, {
      client: redisClient,
      prefix: "myapp:",
      // ...
    });
  }
}
