HTML, CSS, JavaScript, and jQuery are the programming languages used by front-end developers to create web pages.

So to become a front-end developer, the most crucial task is to learn the basics along with writing semantic HTML, conventions, best practices, forms, validations, etc.

Other than that a front-end developer also needs to learn about accessibility, layouts, responsive designing, DOM manipulation, ES6, modular JavaScript, hoisting, scope, event bubbling, strict, Shadow DOM, and the basics of SEO.

  • Acquire Basic Knowledge of Version Control Systems

Version control is the system used by developers to keep track of all the changes made in the source code of the software development project over time.

It also stores information like who made the changes and what changes were made by creating a separate branch for every contributor. Moreover, these changes are not merged with the original source code before they get analyzed.

Web security is the part of information security that deals with the security of web apps, websites, and web services. It refers to the security measures taken by developers to protect their web apps or websites from cyber attacks.

Read: Cybersecurity Trends

To design the front-end of a software application, you need to get basic knowledge of HTTPS (Hypertext Transfer Protocol Secure), CORS (Cross-Origin Resource Sharing), OWASP (Open Web Application Security Project) Security Risks, and Content Security Policy.

  • Learn About CSS Preprocessors and CSS Architecture

As a front-end developer, you have to learn different technologies that make working on the project much easier. A few of these technologies and tools you need to know are CSS preprocessors and CSS Architecture.

Read: What is Custom Web App Architecture

To help you understand, we have defined each of these technologies below.

While CSS Preprocessors like SaSS and PostCSS are an extension of CSS that comes with advanced features to be used by developers to create projects with more features easily. They allow developers to use logic like nesting, mixins, inheritance, variables, and mathematical operations in the CSS code.

It can be difficult to deal with CSS in large, continuously iterated, complex systems. However, some CSS Architecture methodologies allow writing more manageable CSS like BEM ( Block, Element, Modifier).

  • Understand Build Tools

Build tools are programs through which the creation of executable apps from source code can be automated. It includes compiling, packaging, and linking the code in an executable format. It helps in automating repetitive tasks that would otherwise waste a lot of your time.

As a front-end developer, you will need to know about build tools like package managers, task runners, module bundlers, and module loaders.

A package manager is a software tool collection that is used to automate the process of configuring, installing, updating, and removing application programs. Package managers handle the distribution of data and software in archive files - packages. Some of the package managers you must learn about are npm, yarn, pnpm, etc.

Task Runners runs off a configuration file and is used to automate repetitive tasks like testing, linting, and minification. Grunt and npm Script are the most popular examples of task runners. For linting, you can go for ESLint.

Module Bundlers are used to bundle pieces of JavaScript code and their dependencies into one file for browser use. While Module Loaders are used to interpret and load an already written at runtime. Some examples of module bundlers/loaders are Webpack, Browserify, Vite, esbuild, Parcel, Rollup, etc.

  • Pick a Framework

A software framework serves as a foundation for building software applications and is associated with a programming language. Frameworks differ in their functions and capabilities. It also helps in establishing rules and defining the structure of the application.

Although there are multiple frameworks in the market for front-end development, some popular ones are React, Angular, Vue.js, Svelte, Solid JS, etc. for JavaScript, and Mantine, Chakra UI, Daisy UI, Material UI, Radix UI, and Tailwind for CSS.

  • Learn to Test Your Web Apps

Before releasing the app in the market, it is important to ensure that all the required functionalities and features are working properly. Also, it is essential to identify any sort of unintended functioning in the app - called bugs. To check that, we test the application through different methods including integration testing, unit testing, and functional testing.

Read: Best Tech Stack for Web App Development

Cypress, Applitools, Jest, Playwright, react-testing-library, Selenium, Katalon, and Squish are some popular tools used for front-end testing of web applications. And as a front-end developer, you need to know at least one or two of them.

  • Understand Authentication Strategies

To verify the user's identity, a web app or website should have authentication tools/methods/technologies to grant access to a restricted resource. A few popular authentication strategies are Session-based authentication, Token based authentication, OAuth, Basic authentication, SSO (Single Sign On), JWT (JSON Web Token), etc.

  • Acquire Knowledge of Web Components

A suite of different technologies using which you can create reusable custom elements while keeping their functionality encapsulated from the rest of the code is web components. Some of these web components that you will need to know about are HTML templates, Shadow DM, ESModule, and Custom Elements.

  • Learn Typecheckers

Type checking helps developers to verify and enforce constraints of types in values. It ensures that the written code has fewer bugs by trying to catch type errors and removing them from the code. Typescript is one of the most used JavaScript type checkers used by developers.

A progressive web app (PWA) is a website with enhanced features to function like a native, installed app on supporting platforms. PWAs are delivered through web built using front-end technologies.

Read: Why Progressive Web Application Development Is Trending

To build a PWA as a front-end developer you need to have basic knowledge of storage, web sockets, server-sent events, service workers, PRPL pattern, RAIL model, performance metrics, Lighthouse, and DevTools. Knowing Web APIs for location, notification, device orientation, credentials, and payments is also required.

  • Learn Server-Side Rendering

SSR is the ability of an application to convert a static HTML file on the server into a completely rendered/interactive HTML page for the client. It also addresses the search engine optimization and performance issues of single-page web apps. Thus, server-side rendering is another technique that you must be aware of as a front-end developer.

  • Understand Static Site Generators

Want to build a static HTML website with a set of templates and some raw data? Instead of doing so manually, you can use static site generators like Astro, Next.js, GatsbyJS, Gridsome, Elevently, Jekyll, Hugo, Nuxt.js, Remix, and Vuepress to achieve your goals.

  • Learn GraphQL

It is an open-source data manipulation and query language for APIs (Application Programming Interfaces) that also acts as a runtime for processing queries with existing data.

Using GraphQL, you can make multiple resource requests in a single call, reducing the trips to the server and saving a lot of bandwidth and time.
