Are you a starting front end developer's journey? Then this roadmap is for you. You'll get to know all the essential aspects and steps required for frontend web developer.🤩

What Is a Front-End Developer?

Generally, a front end web developer executes web designs through coding languages like HTML, CSS, and JavaScript, which run on the Open Web Platform or act as compilation input for non-web platform environments (i.e., React Native). In a way, a front-end web developer is responsible for implementing visual elements that users see and interact within a web application.

But that's not the scene anymore. Nowadays front-end developers are not limited to specific. You can see their work everywhere—in the navigation, layouts, even the way that a site looks different from your phone (thanks to mobile-first or responsive design).

Now, let's head to the roadmap first.

Below is the chart demonstrating the paths that you can take to become a pro frontend developer. This chart is made by Kamran Ahmed. Kamran’s work is excellent so be sure to star the repo and subscribe to his newsletter to support his efforts.

5. Get familiar with the tools that you will be using.

To become a front-end developer, you should spend some time on learning tools that you will use as a web developer like built tools, unit testing tools, debugging tools, etc.

Well, users are going to interact with your websites through a web browser. The way your site is rendered by these browsers is going to be a big part of whether your work is successful or not. So, it'll be great to know about the tools that can help you to develop a satisfying app/website/product.

All modern web browsers come equipped with developer tools. These tools allow you to test and fine-tune your pages in the browser itself, in ways specific to how the browser is interpreting your code.

6. CSS Frameworks

The CSS framework is a code library that abstracts common web designs and makes the designs easier for a developer to implement in their web apps. In simple terms, a CSS framework is a collection of CSS style-sheets that are prepped and ready to use.

7. Frameworks

These are packages containing pre-written, standardized code in files and folders. They give you a base to build on while still allowing flexibility with the final design. Typically, front-end frameworks contain the following components:

A grid that makes it simple to organize the design elements of your website
Defined font styles and sizing that varies based on its function (different typography for headings versus paragraphs, etc.)
Pre-built website components like side panels, buttons, and navigation bars

Following are some of the most used front-end frameworks

i. Vue.js: The Progressive JavaScript Framework

Vue.js is an open-source model–view–ViewModel front end JavaScript framework for building user interfaces and single-page applications.

Front End Testing is a testing technique in which Graphical User Interface (GUI), functionality, and usability of web applications or software are tested. The goal of Front end testing is testing overall functionalities to ensure the presentation layer of web applications or software is defect-free with successive updates. It is a vital skill for any Developer.

i. Unit Testing

Unit testing generally refers to the process of performing, either manually or in an automated way, a set of tests on a single “unit” of code.

It mainly consists of testing isolated parts of the code, as units. These units usually take the form of methods, properties, UI element actions, etc. It is the fastest and cheapest to apply.

ii. End to End Testing

In E2E testing, the developer tests the whole application together and test it as a user would do.

Basically, here developer tests the application’s workflow from beginning to end. The aim is to replicate real user scenarios so that the system can be validated for integration and data integrity.

The following are some helpful tools:

You can check this detailed guide on End to End Testing.

iii. Integration Testing

Integration tests make sure that various parts of the app work together. It is one of the crucial and most important tests.

For detailed info check the article on Frontend Testing.

9. Server-Side Rendering

Server-side rendering (SSR), is the ability of an application to contribute by displaying the web-page on the server instead of rendering it in the browser. The Server-side sends a fully rendered page to the client; the client’s JavaScript bundle takes over and allows the SPA framework to operate.

10. Static Site Generator
