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

“How to implement Angular 10 + Nodejs JWT Token Based Authentication with MySQL Example?” is always a big common question in development world? So in the tutorial, I guide you very clearly how to build a full stack example to demonstrate an JWT Authentication flow from Angular (signup & signin with by JWT Token) to backend: Nodejs and database MySQL.
Now let’s go!

Tutorial: “Angular 10 Spring Boot JWT Authentication Example with Angular 10 + MySQl + Spring Security – Angular 10 Spring boot Login Example”
In tutorial ‘Angular 10 + Spring Boot JWT Token Based Authentication Example’, I guide you very clearly how to implement full stack example to demonistrade an jwt token based authentication flow from frontend Angular10 to backend: SpringBoot and MySQL.
– I give you an Epic of the application, a fullstack excutive flow from frontend Angular 10 to backend jwt SpringBoot Security to database (MySQL/PostgreSQL) with overall architecture diagram.
– I give you a layer diagram of Angular Jwt Authentication application with localStorage and Angular HttpClient (plus Interceptor)
– I guide you detail-steps how to implement a security SpringBoot Jwt Token Authentication.
– I guide you step by step how to develop a Angular Jwt Authentication application.
– Finally, I do an integrative testing from Angular 10 to Jwt Based Token SpringBoot Security RestApis.

Tutorial: SpringBoot RestAPI Upload Excel file to MySQL – SpringBoot Upload/Import and Download/Export Excel files to MySQL
Creating SpringBoot RestAPIs to upload/import and export/download Excel files to databases: PostgreSQL or MySQL is one of the most common question in the development world. Going through the tutorial post, I explain details “How to read data from Excel Sheet and insert into Database table in Spring Boot RestAPIs with Upload/Download Excel functions” by step to step with coding and give you 100% running source code. What we will do?
– I draw full diagram architecture of SpringBoot Upload Download Excel files service.
– I implements how to Excel File service using
– I implement SpringBoot Upload Download files RestApis.
– I use Spring JPA to interact with database MySQL.
– I implement a global exception handling to deal with a big uploading file
– I use Ajax and Bootstrap to develop frontend for uploading and downloading excel files.
