sequelize-node

store your sequelize instance in module. why? you can access this instance everywhere, for example use different modules without dependency in your app code.

Install

npm i sequelize-node --save-dev

Using

const { Sequelize, db } = require('sequelize-node');

const { sequelize } = new Sequelize(database, username, password, options);

// sequelize === db.sequelize === sequelize instance

You can use that as singleton in all your modules.
