Ten Skills Required for Web Developers (2021 Update)


Hello World was probably the first web page most of us developed as kids. What’s amazing about this is how relevant HTML still is. At the heart of web development, HTML is responsible for how the internet works today.

Technology allows you to develop custom websites with unique (and advanced) features and functionality. Knowing HTML also allows you to better create CMS modules and gives you an edge in implementing SEO strategies at the backend level. For the uninitiated, HTML5 is the latest and you should definitely start learning that.


Abbreviated as Cascading Style Sheets, working on CSS was the next step in web development because it defined how a page created with HTML would be presented on the Internet. Through layouts, fonts, colors, styles, etc., CSS visualized a static web page.

Recently, however, CSS has become more and more vital due to the different screen sizes prevalent in the market today. CSS is now responsible for making web pages responsive and fluid depending on the screen from which a web page is accessed.


There has been a significant evolution in terms of content consumption over the decades. Simple passive spectators of information, we, as consumers, expect more and more interactivity and dynamics on the pages we access online.

This is where JavaScript comes in.

It takes an otherwise redundant webpage and turns it into an immersive experience. It defines the functionality of a web page and allows you to incorporate graphics, animations, gamification concepts, etc. You don’t want to skip your JavaScript classes if you’re a budding web developer.

Git and Github

A web developer must be smart and agile in their work. When something goes wrong in the development process, you can’t afford to start a project from scratch. This is why it is essential to learn version control like Git and Github. This allows you to keep a consistent record of your development process so you can roll back to a previous version if something goes wrong. A full-stack web developer working under tight deadlines absolutely needs this skill.

At least one JS library

Most projects that enter the development phase have a minimal time to market. Coming from competitive requirements and trends, project managers are committed to developing projects within very short deadlines.

As a developer, one cannot simply work line after line of code to develop websites and projects. This is why JavaScript libraries are inevitable. Launched to reduce your development time and expense, knowing at least one JavaScript library will save you from having the worst Wednesdays and Fridays of your career.

Knowledge of BrowserDev tools

All the effort and hard work you put into website development as part of your comprehensive development projects will need to reflect on the browsers visitors use to access your website.

A browser does your work and makes your website fully functional as you intended. That’s why it’s important to test how your website works and responds across multiple browsers. To help you do that, there are tons of BrowserDev tools (Chrome DevTools and Firefox DevTools) that let you debug, test, edit CSS and HTML elements, make changes, and fine-tune your work.

Different types of APIs

A website is never standalone. Even enterprise web development involves interactions with a third party element due to various dependencies. A simple example is when you need to embed a YouTube video on your website.

When such data is involved, it becomes necessary to maintain the functionality of your websites without sharing your website code. This is where APIs come in and help you achieve this intent. As a web developer, the ideal APIs we recommend you master include CRUD operation, data formats, RestAPIs, and HTTP request methods.

Back-end technology

Full-stack web developers are expected to be versatile. Not only the frontend, they also have to work on the development of the backend. This means that they must know databases, servers, etc. to handle requests, find ways to store, access, and retrieve data, and perform other complex tasks. To do this, you must master server-side languages ​​such as HTTP and MySQL.

Problem solving and logical reasoning skills

Developing a website is a challenge and a web development roadmap is filled with hurdles, hurdles and concerns that developers must constantly address to make a website airtight. It is therefore imperative that web developers be expert problem solvers who also possess superior reasoning skills.

Whether it’s fixing syntax errors and workflow flaws or discovering a whole new way to deploy unique website functionality, the challenges to overcome dictate those skills. If solutions are difficult to find, developers should at least know where to look for probable solutions. Hint: Stackoverflow.

Project management tools

Statistics reveal that nearly 80% of companies spend more than half of their development time on rework. This not only delays the time to market, but also incurs additional expense for the staff and other teams involved.

This is why web developers must also be excellent project managers, knowing which development methodology to implement for which project, understanding resource allocation strategies, recognizing scope drift, and having B plans. , and more. No matter the size of the projects, quality delivery is essential and project management tools and techniques can help a developer achieve this.

DevOps and deployment

Once the web development process is completed, it needs to go live for users all over the world to access and build traffic. For this, knowing how to deploy codes is necessary. Deployment involves implementing your code on the cloud, SaaS providers like Amazon Web Services, etc. Besides deployment, it is also essential to know how to migrate and scale websites. If your project involves moving from one host to another or adding new features or capabilities to handle massive traffic, these skills come into play.

Writing test cases and test scenarios

Most developers neglect this step altogether or downplay the importance of writing tests. However, this phase can save you time and make debugging and developing your project seamless. When you write test cases, you make your websites and projects more robust and functional. The sooner you realize this, the more time you can save on your projects.


So these are the essential skills that every web developer should know. If you know a majority of them, we can assure you a good year 2021. If you have not yet mastered several skills that we have listed, you have the whole year ahead of you to learn, evolve and become a better web developer.
