In this article, we will learn the generation and usage of the refresh token in .NET6 Web API application. Click here to understand the implementation of the JWT token in .NET6 Web API. Refresh Token: When the JWT access token expires to renew it without user credentials we will use the Refresh Token. Let's understand the flow of  Refresh Token. The user sends valid 'User Name' and 'Password' to the server, then the server will generate JWT Access Token and Refresh Token sent as a response The JWT Access Token is a short live token(eg 20 minutes) and Refresh Token is a long live token(eg: 7 days) Now client application sends a JWT access token in the request header that makes the user authenticated. If the JWT token expires then the server returns 401 unauthorized responses. Then the client sends the refresh token to the server to regenerate the JWT Access token. The server validates the refresh token and returns a new JWT Access Token and a new Refresh Token as a r

In this article, we will implement a .NET6 Web API that consumes the Azure Cosmos DB. Azure CosmosDB: Azure Cosmos DB is a fully managed NoSQL database. NoSQL says data will be stored as a key/value JSON document. Cosmos DB provides 'High Availability' and 'Low Latency' for any application. Cosmos DB is very quick in response delivering, auto-scaling, effective auto failure management, etc. Any existing application that works on different DBs can be easily migrated to Azure CosmosDB as it provides APIs for integration like 'SQL/Core API'(most recommended API, our demo uses this 'SQL/Core API'), 'MongoDB API', 'Cassandra API', 'Germlin API', 'Table API'. Let's understand the structure of the Cosmos DB: Create an Azure Cosmos Account with an appropriate subscription inside of the Azure portal. After creating the Cosmos Account, we can manage the data of our account by creating 'Database', 'Containers', an

In this article, we are going to implement a sample in .NET6 Web API to send emails using the SendGrid Nuget Package. Create A .Net6 Web API Project: Let's create a .Net6 Web API sample application to accomplish our demo. We can use either Visual Studio 2022 or Visual Studio Code(using .NET CLI commands) to create any.Net6 application. For this demo, I'm using the 'Visual Studio Code'(using the .NET CLI command) editor. CLI command dotnet new webapi -o Your_Project_Name SendGrid: SendGrid is a third-party email provider from which we can deal with 'send', and 'receive' operations of email to our application. SendGrid SMTP(Simple Mail Transfer Protocol) provider for email transfer. SendGrid also provides SendGrid .Net NuGet package that provides easy configuration to any .NET applications. So to use the SendGrid SMTP we need 'Auth Key', 'From Email', so let's register into the SendGrid. The following are the steps to register and

The main objectives of this artice are: Creating Angular 13 Application. Install And Configure Bootstrap Add Bootstrap Menu Angular: Angular is a framework that can be used to build a single-page application. Angular applications are built with components that make our coding cleaner and maintainable. Angular component composes of 3 files Typescript File(*.ts), Html File (*.html), CSS File(*.css). Components typescript file and HTML file support 2-way binding which means data transfer is bi-directional. Component typescript file listens for all HTML elements events from the Html file. Create Angular(v13) Application: Let's create an Angular(v13) application to begin our sample. Make sure to install the Angular CLI tool into our local because it provides easy CLI commands to play with the angular application or to set up the application. Command To Install CLI: npm install -g @angular/cli Run the below command to create an angular application. ng new name-of-your-project
