How to Configure Entity Framework Caching

,
Entity Framework

Caching With Entity Framework

The Entity Framework is a set of technologies in ADO.NET that support the development of data-oriented software applications. With the Entity Framework, developers can work at a higher level of abstraction when they deal with data and can create and maintain data-oriented applications with less code than in traditional applications.

NCache introduces the caching provider, which acts between Entity Framework and the Data source. The major reason behind the EF Caching provider is to reduce database trips (which slow down application performance) and serve the query result from the cache. The provider acts in between the ADO.NET entity framework and the original data source. Therefore, the caching provider can be plugged without changing/compiling the current code.

MicroProfile CustomConfigSource With Database

,
Using MicroProfile, let’s see how to deal with configuration properties in an application.

With the MicroProfile-Config API, there is a new and easy way to deal with configuration properties in an application. The MicroProfile-Config API allows you to access config and property values from different sources, like:

  • System.getProperties() (ordinal=400)
  • System.getenv() (ordinal=300)
  • all META-INF/microprofile-config.properties files

Developers can find a good introduction into the MicroProfile Config API here. Of course, developers can also implement your own config source. However, most of the examples are based on reading custom config values from an existing file, like in the example here.

React Web Development: A Guide to Develop Progressive Web Applications

,
Build progressive web applications in minutes

Progressive web applications (PWAs) quickly gained popularity because they are web performance applications based on fast performance, streamlined to provide a mobile app-like experience. PWAs are built using HTML, CSS, and JavaScript to create a level of availability and performance equivalent to that of native mobile applications. They respond quickly, consume less data, store more space, and support push notifications and offline use in the browser.

Building a progressive web application has now become the web development trend that every business wants to follow. Significant players like Twitter and Flipboard have recently rolled out their progressive web apps to provide a mobile experience for users, without requiring them to install the app. In this article, you will learn how to build a progressive web application using React. Let’s get started.

Spring Bean Lifecycle: Using Spring Aware Interfaces

,
Through Spring Aware interfaces, you can access Spring bean lifecycle events.

Spring Aware interfaces allow you to look into the inner workings of the Spring Framework. Through Spring Aware interfaces, you can access the Spring context, or Spring bean lifecycle events.

Your Spring beans might require access to framework objects, such as ApplicationContext, BeanFactory, and ResourceLoader. To gain access, a bean can implement one of the many Aware interfaces of the Spring Framework.

Working With Custom Policy in Mule 4

,

MuleSoft Custom Policies can be layered on top of the implementation of the APIs to provide the governance, security, and visibility required. While the out-of-the-box API management policies cover the majority of use cases, an organization may need to create a custom policy to meet specific business needs.

There is a lot of documentation that shows how to work with MuleSoft custom policies through API manager, however, developing the custom policy and debugging them locally has been always challenging. In this article, I will demonstrate how to develop and test Mule custom policy on your local standalone Mule runtime instances before uploading to the API manager or Exchange for live running APIs.

Using Junction or Associative Tables in Entity Framework Core

,

When I first encountered Entity Framework (EF), I always gravitated towards a database-first option. Back when Entity Framework appeared, there wasn’t a code-first option.

My thinking towards this approach was your database holds the data. If your database wasn’t designed properly from the start, and you generate your entities based on the database design, your code (entities) may suffer.

Open Source Integration With Apache Camel and How Fuse IDE Can Help

,

Take any integration project and you have multiple applications talking over multiple transports on multiple platforms. As you can imagine, in large enterprises, applications like this can get complex very fast. Much of the complexity stems from two issues:

  1. Dealing with the specifics of applications and transports
  2. Coming up with good solutions to integration problems

Making your applications speak transports and APIs is relatively easy on its own. I’m sure everyone knows how to send JMS messages to their broker of choice; though it still requires in-depth knowledge of the JMS specification, which many developers may not have. On top of that, what happens when you want to route that JMS message to another application? You then have to take care of mapping the JMS message to the application plus handle any new concepts related to the application. Add a dozen other applications into the mix and you’ve got quite a headache on your hands.

Custom DynamoDB Docker Instance

,

Hey guys, I hope you all are doing well. I am back with another article on custom docker instances for databases. In my last post, we saw how we could have our custom docker instance for MySQL. Similarly, in this post, we will see how we can do the same with DynamoDB, so let’s get started.

Just like the scenario in the previous article, I was working on a project with DynamoDB as the database due to its many features like scalability, cloud storage, etc. And I wanted to test some things and did not want to mess with the cloud instance, so I thought to make an instance of my own, so what to do?
