TSĒVO • Technology Stack

What is a technology stack?

A tech stack is a combination of software products and programming languages used to create a web or mobile application. Applications have two software components: client-side and server-side, also known as front-end and back-end.

Each layer of the application builds on the features of the one below it, creating a stack. This diagram shows the major building blocks of a typical tech stack, but there can be other supporting components included.

Back-end tech stack

The back-end contains the business logic that works behind the scenes to drive your application. Users will never directly engage with the back-end, all information is passed back and forth through the front-end.

Front-end tech stack

The front-end is the visual part of your application that users will see and interact with. This interaction can happen through a web browser or a mobile app.

When building for the web, the front-end tech stack is made up of:

  • HTML (Markup Language)
  • CSS (Style Sheet Language)
  • JavaScript (Scripting Language)

Front-end frameworks also help provide a better user experience: AngularJS, Backbone.js, ReactJS, jQuery, Twitter Bootstrap, and others help to add functionality to the application that is normally only experienced in native software. For a mobile app the tech stack is simply comprised of an iOS or Android app written in Objective-C/SWIFT or Java, respectively.
