Nodejs/Express CSV Upload Download to MySQL/PostgreSQL – Multer, Fast-CSV, Json2Csv, Sequelize

Tutorial: Nodejs/Express CSV Upload Download to MySQL/PostgreSQL – Multer, Fast-CSV, Json2Csv, Sequelize

In the tutorial, I will introduce how to build a Nodejs/Express RestAPIs application to upload/import and download/extract data from multiple CSV files to MySQL or PostgreSQL database by:

  • Express is used to build Nodejs RestApis
  • Multer is used to upload/download CSV files
  • Sequelize ORM is used to manipulate data with MySQL/PostgreSQL
  • Json2csv is used to save data objects to CSV file
  • fast-csv is used to parse CSV file to data objects
