In this article, we will implement the File Upload to Azure BLOB using the Blazor Web Assembly application. In one of my earlier articles, I have explained the File Upload to Azure BLOB using Node.js. You can read about it from this link .  After publishing that article, I have received feedback from some of my students that, I should also explain the File Upload steps using Blazor Web Assembly assembly, and then I have decided to work on it.  I have already published some articles on Blazor. You can read them from the following links 1. ASP.NET Core 5 and Blazor Web Assembly Apps: Token Based Authentication in ASP.NET Core 5 APIs and Authenticating it using Blazor WebAssembly Apps 2. Blazor WebAssembly: Uploading Image to ASP.NET Core 5 API from Blazor WebAssembly Project 3.

In this article, we will implement the database operations on PostgreSQL using Node.js and Sequelize ORM. PostgreSQL is an Open-Source, powerful object-relational database system. This database supports various features. The detailed features of this database can be read from this link .  This article is written for the audience those have basic knowledge of Node.js and Express. What is Object-Relational Mapping (ORM)?     ORM is a technique of mapping the data schema from the database with the Object-Oriented representation in incompatible systems. The application that needs to connect to the database for performing various database operations, can use these objects to perform read/write operations instead of using typical database syntax like select, insert, update, delete queries. Various server-side technologies like JAVA, .NET, .NET Cors use various ORM frameworks like Hibernate, EntityFramework, etc. to map with database schemas (table) and perform read/write operations. While us

 Uploading File to Azure Blob using Node.js and Express-FileUpload  Recently, I was working on an assignment for storing of the   information  captured from the client application  on the Azure cloud. This application is developed using JavaScript Full-Stack with Express and Node.js on the server-side. I was supposed to accept images from client and upload them to Azure Blob Storage using Node.js application.  To implement this, I have explored various ways like Multer package and Express-FileUplaod. After doing some research I have implemented the requirement. But then I have decided to put my thoughts in the form of this article.  In fact, I have already written an article on similar requirements which you can read it from this link .  In this article, we will see how to use an express-fileupload to upload file to Node.js Server Application  and further uploading it in Azure Blob.  The figure 1, will explain an idea of the application implementation Figure 1: The idea of file upload
