痛点

开发者在 Node.js 项目中使用 Prisma ORM 和 express-session 时，需要手动创建 Session 模型来同步数据库中的会话表，否则 Prisma 无法感知该表的存在，可能导致后续迁移冲突。用户认为这种手动同步方式“ugly”，希望框架能自动处理会话与数据库的同步，但现有方案要么依赖第三方库自动建表（如 connect-pg-simple），要么手动定义模型并维护映射关系。这造成了额外的配置工作和心理负担，尤其是当需要扩展会话功能（如手动撤销、展示活跃会话）时，手动模型又显得必要，导致开发者陷入两难：自动建表缺乏控制，手动模型又不够优雅。

Stack Overflow question

I have a node js code that authenticates with cookies and sessions: import express from "express"; import session from "express-session"; import postgreSession from "connect-pg-simple"; import { Pool } from "pg"; const app = express(); const PostgreSession = postgreSession(session); const pool = new Pool({ connectionString: process.env.DATABASE_URL }); app.use( session({ store: new PostgreSession({ pool: pool, createTableIfMissing: true }), secret: process.env.SESSION_SECRET, resave: false, saveUninitialized: false, cookie: { httpOnly: true, secure: false, maxAge: 60 * 60 * 1000 }, }), ); and prisma schema. Do I really have to create new model Sessions to keep in sync database and schema? Is there a better approach, something where the prisma(or maybe some other frameworks) handle everything related to keeping in sync sessions in database and schema themselves? Some say to manually create model in prisma: model Session { sid String @id sess Json expire DateTime @@map("session") } I don't know why, it just looks a bit ugly.

I’m not sure I understand. If you want persistent sessions an db seems like a good place for it, and it looks like this is a durable session wrapper—what would you use in its place?

You can technically let connect-pg-simple create the table for you, but I think it's better to create a prisma model for the sessions table and migrate to make prisma know that a session table exists, and avoid any issues later with migrations. I don't really get why you think it's ugly, but you can change the name of the properties to friendlier names and use @map to map them correctly to the column names on the db. I personally always create a model for sessions and extend it with my own properties, for features like manually revoking sessions and for example showing users their active sessions and allowing them to terminate them. It can be quite useful sometimes.
