Package Exports

connect-typeorm

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (connect-typeorm) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

connect-typeorm

A TypeORM-based session store.

Usage

Configure TypeORM with back end of your choice:

yarn add @types/express-session connect-typeorm express-session typeorm sqlite3

Implement the Session entity:

// src/domain/Session/Session.ts

import { ISession } from "connect-typeorm";
import { Column, Entity, Index, PrimaryColumn } from "typeorm";
@Entity()
export class Session implements ISession {
  @Index()
  @Column("bigint")
  public expiredAt = Date.now();

  @PrimaryColumn("varchar", { length: 255 })
  public id = "";

  @Column("text")
  public json = "";
}

Pass repository to TypeormStore:

// src/app/Api/Api.ts

import * as Express from "express";
import * as ExpressSession from "express-session";
import { Db } from "typeorm-static";
import { Session } from "../../domain/Session/Session";

export class Api {
  public sessionRepository = Db.connection.getRepository(Session);

  public express = Express().use(
    ExpressSession({
      resave: false,
      saveUninitialized: false,
      store: new TypeormStore({
        cleanupLimit: 2,
        limitSubquery: false, // If using MariaDB.
        ttl: 86400
      }).connect(this.sessionRepository),
      secret: "keyboard cat"
    })
  );
}

TypeORM uses { "bigNumberStrings": true } option by default for node-mysql, you can use a Transformer to fix this issue:

import { Bigint } from "typeorm-static";
@Column("bigint", { transformer: Bigint })

Options

Constructor receives an object. Following properties may be included:

cleanupLimit For every new session, remove this many expired ones. Defaults to 0, in case you need to analyze sessions retrospectively.
limitSubquery Select and delete expired sessions in one query. Defaults to true, you can set false to make two queries, in case you want cleanupLimit but your MariaDB version doesn't support limit in a subquery.
ttl Session time to live (expiration) in seconds. Defaults to session.maxAge (if set), or one day. This may also be set to a function of the form (store, sess, sessionID) => number.
