Web Development 101: Frontend vs Backend Explained

In application and web development, frontend and backend frameworks are two crucial aspects that help users understand how websites and web apps work. These two components construct the core engine of any modern application, serving completely different yet connected purposes. Frontend refers to what the users/audience see and interact with on the website/web app, like layouts, colors, buttons, checkboxes, text and images – this allows users to engage with the webstore/application. Backend refers to the invisible data and infrastructure premise that works behind the scenes to make the website/application work, handling critical tasks like storing and processing application data for the users. 

Although frontend and backend may seem confusing at first, laying out their differences and usage might offer a clearer understanding. Read along to truly understand what frontend and backend are, how are they different from each other, how they work in tandem and the key proficiencies needed to excel at both.

What is Frontend?

The frontend, also known as the client side, is a component of the website or web application that the users directly interact with. As the name suggests, it is a user-facing side of the website and takes care of the entire UI/UX, including all the elements visible on the screen like design layouts, fonts & colors, interactive features, etc. Frontend development is responsible for providing a smooth and convenient user experience to the audience with seamless navigation and web features that foster engagement and recall.

Frontend developers make sure that the visitors are able to properly interact and navigate the website or app, and use different programming languages and design skills to achieve it. Programming languages like JavaScript, HTML, CSS, PHP, Python, etc. are often used to design websites and applications, while frontend frameworks like React, Angular, Vue.js, are also employed to speed up the development.

Although, many of these languages are used in tandem, all of them serve specific purposes – HyperText Markup Language (HTML) is responsible for laying out the structure and content of the website, Cascading Style Sheets (CSS) are components that add design features to the website, and JavaScript allows developers to introduce interactive features to the page. Together, with tools and skills, frontend website development allows businesses an opportunity to create and showcase highly navigable and interactive websites that focus on customer experience, conversions and brand loyalty. Here are some of the top frontend development trends that you shouldn’t miss.

What is Backend?

While frontend remains the clients-facing side, backend refers to the server side of the website or web application, that is responsible for and manages the overall functionality of the website. It is a component which takes care of the behind-the-scenes operations of the website, managing application integration, server logic and database administration. Remaining under the hood, it is the backend operations that aligns and processes frontend requests and returns a response, interacting with database servers, microservices and API calls all along.

The backend is built on layers of protocols and technology – by combining the aspects of concurrency and parallelism, these components handle thousands, if not millions, of data requests simultaneously, optimally distributing them across servers. Backend developers are acquainted with various communication languages and tech required to complete requests – tools like SQL Server and Oracle are required to store and modify data; expertise in PHP frameworks, debugging, version control software, etc. crucial for backend web development services. 

Frontend vs Backend – A Comparative Overview

How Frontend and Backend Work Together – And What To Choose

By now, we know that both the frontend and the backend frameworks are essentially required to run a modern web application or website. Though they serve different purposes, it is their close collaboration that seals the deal. These two frameworks are two sides of the same coin and form the backbone of any functional aspect of a website or app. While the frontend takes care of what the user sees and interacts with, the backend is all about the heavy lifting of data, its processing, database communication and basic functionality. Together, they form a unique synergy and a seamless digital and customer experience. 

For example, in any scenario like a form registration, both the frontend frameworks and the backend frameworks are equally crucial.When the user fills out the form on the website, it is the frontend that captures and and sends over the data to the server; the backend receives the data, processes it and returns a suitable response to the frontend; the frontend then displays a confirmation message or error, based on the server response. 

This back-and-forth of data and requests/responses highlights the intermingled nature of frontend and backend in web development services. It is clear that neither can function effectively without the other – the frontend would become static and limited, and the backend would become inaccessible. 

• The frontend focuses on usability, interactivity and experience
• The backend maintains underlying data integrity, validations and business logic

In modern web applications, the relationship between frontend and backend frameworks is being further enhanced to provide real-time validations, where both these models work parallely for instant feedback, improving the reliability, security and the overall customer experience. Understanding this interplay of how web apps and websites function under the hood is the key to successful software development.

Frontend or Backend – What to Choose

The dynamic intertwined relation of frontend and backend proves to be fundamentally essential for successful web app development. Even though working in tandem, frontend developers and backend developers excel at uniquely different sets of skills and can offer expertise in that domain only. 

• If the project is more focused on web design, user activity & experience and visitor engagement, frontend frameworks are preferred.
• If the project requires data analysis and processing, server maintenance and API management, backend frameworks are more focused on.

All in all, we cannot deny the fact that both these development frameworks are what makes a web app or website run smoothly – one not existing without the other. Mastering the concepts of both these development methods can equip developers and businesses with the tools to build robust and disruptive digital solutions.
