Welcome back to D Guides folks.This post is valuable for newbies for react development.I am sharing about few tools you can use when developing react applications.It is important leaning tools like these same as understanding a framework like React.These tools will help us to maintain high code quality. 1.

Welcome back to D Guides folks.I am breaking the radio silence after several months and I am hoping to update my 'Programming Guides' section on a weekly basis.Today I am sharing about an interesting topic but at first glance it may look like a monster.But it is not.Do you know what is 'Elasticserach'?Elasticsearch is a document oriented database which will store data in JSON document form.Basically it is a search index or a search engine.As the word 'Elasticsearch' implies this concept is to analyse and search your data in real time.The link below will take you to the official documentation of Elasticsearch. Elasticsearch Official Documentation There is another thing called 'ELK' stack which is the acronym for three open source projects:  Elasticsearch , Logstash and Kibana .

Welcome back, folks. After several hectic months, I found some time to write a blog post. I have to apologize for not updating my blog for a long time. Today I am going to write the first post of my new section 'Programming Guides'.This post is about 'Electron' and after reading this you can start building cross-platform desktop apps with JavaScript, HTML, and CSS. I will cover the beginners' guide in the following steps. Introduction to Electron The architecture of Electron Applications Setting up the environment Future plans  Electron JS first released in January 2013 and it was initially known as Atom Shell. The name Electron was given in April 2015. Electron is an open-source framework developed and maintained by GitHub which can be used to build cross-platform desktop application using web technologies. You may wonder after reading my next sentence. Notable software we use in our day to day lives such as Atom, GitHub Desktop, Visual Studio Code...
