Web application development

Web application development is the creation of application programs that reside on remote servers and are delivered to the user's device over the internet. Web apps don't need to be downloaded and instead are accessed through a network. An end user can access a web application through a web browser such as Google Chrome, Safari or Mozilla Firefox. A majority of web applications are written in JavaScript, Cascading Style Sheets (CSS) and HTML5.

Web application development typically has a short development lifecycle led by a small development team. Front-end development for web applications is accomplished through client-side programming. Client refers to a computer application such as a web browser. On the client-side, HTML programming instructs a browser on how to display the on-screen content of webpages, CSS keeps information displayed in the correct format. JavaScript runs JavaScript code on a webpage, making some of the content interactive.

Server-side programming powers the client-side programming and is used to create the scripts that web applications use. Scripts are written in multiple scripting languages such as Ruby, Java and Python. Server-side scripting creates a custom interface for the end user and hides the source code that makes up the interface.

Databases such as MySQL and MongoDB are used to store data in web application development.
