For handling the business processing of our application, We implement a Controller.js that uses exceljs and read-excel-file libraries to write/read data objects to excel files. And for doing CRUD operations with MySQL and PostgreSQL database, we use Sequelizez ORM to finalize the jobs. Project Structure: - config package is used to setup database configuration with Sequelize ORM and Multer’s configuration for uploading file - models package is used to define Sequelize Customer model - routers package is used to define Express router for Nodejs RestAPIs - controllers is used to implement coding to read/write Excel files and interact with database (storing/retrieving) - view package is used to define a html view page for upload/download Excel files - resource/static/js is used to implement Ajax Javascript code to upload multiples Excel files
