PromiseベースのNode.js ORMのSequelizeを使ってPostgresqlに接続してみる sequelize.org
$ npm install sequelize $ npm install pg pg-hstore
DB接続
import { Sequelize } from 'sequelize'; const sequelize = new Sequelize('postgres://user:pass@example.com:5432/dbname')
検証
.authenticate()
を使うと接続ができているかが確認できる
try { await sequelize.authenticate(); console.log('Connection has been established successfully.'); } catch (error) { console.error('Unable to connect to the database:', error); }
