What is a Tech Stack and How Do They Work?

A tech stack is a combination of various technologies that are stacked one over the other to build an end-to-end application. Tech stacks can be different for the front end and the back end.

• MEAN stack: MongoDB, Express, Angular, and Node.js.
• MERN stack: MongoDB, Express, React, and Node.js.
• MEVN stack: MongoDB, Express, Vue, and Node.js.
• LAMP: Linux, Apache, MySQL, and PHP.

There are several factors that you should consider while choosing a tech stack — for example, the size of the application, cost, time to production, scalability, user experience, and security.

Some popular examples of tech stacks are the MEAN stack, MERN stack, MEVN stack, and LAMP.

A stack is a data structure in which objects are placed one over the other. By using a set of technologies, developers get the benefit of added functionalities on top of one technology, each contributing to the workflow. All the technologies can be bundled together, forming a stack, to build an end-to-end application.

For example, a combination of MongoDB, Express, Angular, and Node can be used to create end-to-end web apps, thus forming a technology stack.

A tech stack consists of various frontend and backend technologies. It can be as simple as a JavaScript-based UI, a programming language to code the application logic, and a database to store and retrieve information.

On the other hand, it can be more complex, with multiple workflows, event processing, and data analytics, requiring many technologies to be added to the tech stack.
