Frontend web developers use three primary coding languages to code the website and web app designs created by web designers.
The code they write runs inside the user’s browser (as opposed to a back end developer, whose code runs on the web server). Think of it a little like this: the back end developer is like the engineer who designs and creates the systems that make a city work (electricity, water and sewer, zoning, etc.), while the front end developer is the one who lays out the streets and makes sure everything is connected properly so people can live their lives (a simplified analogy, but you get the rough idea). A front end web developer is also in charge of making sure that there are no errors or bugs on the front end, as well as making sure that the design appears as it’s supposed to across various platforms and browsers.
I’ve combed through dozens of frontend web developer job listings to see which skills are the most in-demand right now. These are the things that real employers are looking for in job applicants today (and will still be looking for in the near future). Master these things and you’re certain to land an awesome frontend dev job!
HTML & CSS
HTML (Hyper Text Markup Language) and CSS (Cascading Style Sheets) are the most basic building blocks of web coding. Without these two things, you can’t create a website design, and all you’ll end up with is unformatted plain text on the screen. You can’t even add images to a page without HTML!
Before you get started on any web development career path, you’ll have to master coding with HTML and CSS. The good news is that getting a solid working knowledge of either of these can be done in just a few weeks.
The best part: HTML and CSS knowledge alone will let you build basic websites.
It’s also the most popular programming language in the world, so regardless of your dev career plans, it’s a super valuable thing to learn.
Front End Frameworks
Experience with CSS Preprocessors
Preprocessors are another element that a front end developer can use to speed up CSS coding. A CSS preprocessor adds extra functionality to CSS to keep our CSS scalable and easier to work with. It processes your code before you publish it to your website, and turns it into well-formatted and cross-browser friendly CSS. SASS and LESS are the two most in-demand preprocessors, according to real job listings.
Experience with RESTful Services and APIs
Without getting too technical on this one, REST stands for Representational State Transfer. In basic terms, it’s a lightweight architecture that simplifies network communication on the web, and RESTful services and APIs are those web services that adhere to REST architecture. Read more about REST and RESTful services here.
Let’s say you wanted to write an app that shows you all your social media friends in the order you became friends. You could make calls to Facebook’s RESTful API to read your friends list and return that data. The same thing with Twitter (which also uses RESTful APIs). The general process is the same for any service that uses RESTful APIs, just the data returned will be different.
While it all sounds really complicated and technical, it’s a simple set of guidelines and practices that set expectations so you know how to communicate with a web server. They also make a web server perform better, scale better, work more reliably, and be easier to modify or move
