User Authentication schemes in a Multi-Tenant SaaS Application

User Authentication in Multi-Tenant SaaS Apps Introduction We will cover few scenarios that we can follow to perform the user authentication in a Multi-Tenant SaaS application.

Handling exceptions in the Executor service threads in Java

Introduction This is a continuation post on the exception handling strategies in the threads in Java. For Introduction, please read this post The second post is available here This post addresses the problem statement "How to use the exception handlers in the threads spawned by the Executor Service in Java?" Not all times, we will be using Thread  classes to run our threads because we have to manage a lot of the underlying logic for managing threads. There is ExecutorService in Java which comes to the rescue for the above problem. In the previous posts, we have discussed on how to handle the exceptions in plain threads. However, when using executor service, we do not create / manage threads, so how do we handle exception in this case. We have a ThreadFactory   as an argument which can be used to customize the way threads are created for use within the ExecutorService . The below snippet of code leverages this feature to illustrate the exception handling, wherein we create a

Async implementation in Blazor

Step-by-Step Guide to Achieving Async Flows in Blazor: 1. Understanding Asynchronous Programming: Before delving into Blazor-specific async flows, it's crucial to understand asynchronous programming concepts like async and await . Asynchronous operations help improve the responsiveness of your UI by not blocking the main thread. 2. Blazor Component Lifecycle: Blazor components have their lifecycle methods. The OnInitializedAsync , OnParametersSetAsync , and OnAfterRenderAsync methods allow you to implement asynchronous operations during various stages of a component's lifecycle. 3. Asynchronous API Calls: Performing asynchronous API calls is a common scenario in web applications. You can use HttpClient to make HTTP requests asynchronously. For example, fetching data from a remote server: @page "/fetchdata" @inject HttpClient Http @ if (forecasts == null ) { <p> < em > Loading... </ em > </ p > } else { <table>
