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);
}
