Lazy Loading of Feature Module in Angular 7

whenever angular application is loaded then its all modules are loaded eagerly i.e  entire application is loaded at client side on first request made to server. This cause over utilization of the resources and slows down the application at least at first time.

Just take example for E-commerce website which will have several module like order module, Feedback module, Cart Module, Product module and etc. But suppose your require to give feedback for some product you have bought and you visited to feedback page but now instead of loading just

Feature Modules in Angular 7

Feature Module Whenever we  create angular application we go on adding components to angular application. But as our application goes on increasing it become to much problematic to maintain such application. Every feature of our application is binded under single module which we call as app module. Which is root module of our Angular 7 application. While developing angular application without modularizing its features creates several problems  Application is not easily scalable.Application is tough to maintain.Application complexity makes it hard to understand. Solution Here feature modules comes for our rescue. Feature modules help angular applications to get modularised on basis of features present in our application. As our application grows we can divide our entire application in small feature using feature module. Feature modules helps in creating boundary that separates our specific functionality or say features. Feature modules communicates with other module or root module usin…

Decompose Monolithic Application To Microservices

How To Decompose Application into Microservices. After reading the previous two posts you all must be excited to implement microservice architecture to your application and that's good you should be ready to implement something new that might boost the application performance,  maintenance, scalability and will make your application future proof. But have you ever thought how will you be breaking your application into micro application i.e microservices. Think about it for some minute exercise your brain for some time before reading the below tutorial.

Now i am sure that you all might  have come through excellent ideas for breaking up your application in microservices. Please feel free to mention your valuable ideas in comment so that other or even me can be benefited by your ideas.

Now before breaking your application into micro-services you should consider following points.
Points to be considered before creating microservices.Your each services should be easily testable.Your a…

Monolithic Application Architecture

In regular web development process what do we do? We create one war file which contains all functionality, services, modules or all use cases related to our business. In this approach of development we do not focus to make our application modularise. We may be following modularization in our code but end product is not seperated. Every services, modules are bundled up in single war and this war is deployed on server so that our business will be available for outside world which can make a request to get the required resources. This native architecture of development is called Monolithic Architecture.

Micro Services, A Quick Introduction.

What is Micro Services.By the name it is clear that we are talking about mini services which are able to perform their task independently. Micro Services follows micro service architecture instead of monolithic architecture. Whenever we say that application build on microservices architecture that means that this application is not dependent on one services but rather it is dependent on several many services. 
Whenever a request is made through application UI by the user then that application is calling different other services for fulfillment of the
