The differences between front end, full stack and backend development

Web development is not just one thing. It encompasses multiple skillsets. And there are different kinds of careers within the web development space. Three terms often used are front end, backend and full stack development. In this article, we will point out the key differences between the three.

Front-End Web Development

Front-end development, while its components are always changing, essentially deals with the outer-facing parts of a website or web application. To clarify, front-end development involves HTML, CSS, and JavaScript:

backend development
  • HTML: HyperText Markup Language, or HTML, is the key structural component of all websites on the Internet. Without it, web pages cannot exist.
  • CSS: CSS adds style to HTML. I like to use the analogy that HTML is like a face and CSS is like the makeup.
  • JavaScript: JavaScript, or JS, has been evolving over the last several years. In relation to front-end development, JS is important because it helps make web pages interactive.

The front end is associated with layout and design principles. But front-end developers are not necessarily designers. Basically, front-end developers construct the outward appearance. The website pages that users see. To clarify, the front-end developer must take into consideration the readability and usability of the site and/or application. Moreover, the front end runs on the client. It means the user’s local computer – in most cases – the web browser. And information is not stored on the client side.

BackEnd Web Development

Backend web development is what goes on behind the scenes. The back end enables the front-end experience.

To make things easy, think about the front end as part of the iceberg above the water. The backend development is the rest of the ice. User can not see it. But it is the most fundamental element of a web application. The backend runs on the server.

Unlike the front-end development (which primarily uses HTML, CSS, and JavaScript), backend development can rely on a range of languages and frameworks.

A few popular languages used on the backend development include:

  • Ruby (often used in conjunction with the Rails framework — AKA Ruby on Rails)
  • Python (which is often used with the Django framework on the back end)
  • PHP (the popular WordPress CMS uses PHP on its back-end — PHP has a few popular frameworks, one being Laravel)
  • Node.js (getting more popular — this is a back-end environment for web apps built with JavaScript)

In order for large-scale websites and web applications to work. It’s more than a backend language and framework. All of the information on a website or application must be stored somewhere. This is where databases come in. So, backend developers handle these as well.

Popular databases include:

  • MySQL
  • PostgreSQL
  • MongoDB

Typically certain backend languages/frameworks require a certain database. For example, the MEAN full stack framework requires MongoDB.

Beyond knowing a backend language/framework and running databases, back-end developers also must have an understanding of server architecture.

Setting up a server properly allows a site to run fast, not crash, and not give errors to users. This falls under the backend developer’s domain because most errors occur at the back end, not the front end.

Full Stack

Full stack is the combination of both the front end and the back end. To clarify, a full-stack developer is a jack-of-all-trades. They are responsible for all levels of development, from how the server is set up to the design-related CSS.

These days, there’s so much that goes into web development that it’s almost impossible to handle both sides. While many people can claim to be full stack, or in fact are, they still typically focus more on one side: the client or the server.

At smaller companies/startups, a single person would more likely be responsible for all sides of the web development spectrum. However, at larger companies, people work on teams and have specialized roles. One focuses solely on server architecture. And another (or a few people) are on the front end, etc.

To sum up with frontend, full stack and backend development

Web development has many faces. And it’s evolving more every day. There’s a lot to learn, but don’t feel pressured to learn everything at once. Remember, in workplace environments, you’ll usually be on a team with others. Moreover, focus on honing your skills in one aspect of web development at a time. Don’t get overwhelmed, and you’ll be a pro before you know it.
