Full-stack Development

Full-stack Development in simple terms means that the development of the front end (client side) as well as the back end (server side) of an application is done by a single developer. In the simplest of terms, a full-stack developer is a developer who knows how to work with all the layers of an application, from the top user interface down to the bottom of the server. This flexibility allows full-stack developers to manage a large number of activities and responsibilities in a particular project and that is why they are indispensable in the sphere of software development. 

Front-End Development (Client-Side) 

The client-side of an application is the layer of the application that the end user interfaces with. It covers the looks and the structure of the application as well as the part of the application that the user can directly interact with (UI). Front end development is the part of development that is responsible for the look and feel of the application and the ease of use of the application and interface. 

Key technologies and tools used in Front-end

HTML (Hypertext Markup Language)

The language which is used for the creation of web sites and applications particularly those which are based on the world wide web. It offers the framework for a web page. 

CSS (Cascading Style Sheets)

A script lingua that is used to define the look of a document that is coded in HTML. CSS is used for the presentation of the web pages and it includes the design of the layout, colors, fonts, etc. 

JavaScript

A programming language that is used to enhance the features of website and add some functionality like change in content dynamically, validation of forms, adding effects and many more. 

Front-End Frameworks and Libraries

Frameworks such as React, Angular, and Vue. It includes libraries of js that offer reusable components and help in the creation of intricate user interface. 

 Front-end development is the process of designing and implementing the application in a way that is easy to use and interactive with the user and changing the appearance of the application according to the type of device and screen that the user is using. 

Back-End Development (Server-Side) 

The back end of an application, however, is the part that cannot be seen by the user. It consist of the server, the database and application logic that drives the front-end. It is the back-end development that deals with data, the logic of the business and the operations that enable the application to run. 

Key technologies and tools used in Back-end

Programming Languages

Some of the popular programming languages include; Python, Java, Ruby, PHP, and Node. It is widely used for the same and is written on the server side. These languages are used to write the code of the back end, to control the requests and responses as well as the interactions with the database. 

Databases

These are data base that contain the data that is necessary for the application to function as it is required. Popular DBMS are MySQL, PostgreSQL, MongoDB and Oracle. Some of these systems are accessed through what is known as Database Query Languages such as SQL. 

Web Servers

Technologies included for serving the application include Apache, Nginx or Microsoft Internet Information Systems commonly referred to as IIS will take in requests from the front end to return a response.

APIs (Application Programming Interfaces)

APIs are a mean that enables the different parts of the application to interact with each other and also with external services. RESTful APIs and GraphQL are probably the most usual approaches to describe such communication and specify how it is organized. 

This is the development of the application back-end to make sure that the application is able to process data and information, undertake complex operations as well as provide the required information to the front-end without jeopardizing on matters of security, performance and scalability.

Full-stack Development 

Full-stack development is the term used when the front-end and back-end development is done by a single person. A full-stack developer is a developer that can work in every layer of the application from the user interface layer through to the server and database layers. This means that one needs to be knowledgeable in several areas and have an idea of how one part of the application links with the other and what happens when one part is altered. 

The benefits of Full-stack development include

Efficiency

Full-stack developers can work on both the client side and the server side, this means that there is no need for hiring different specialists to do the work and the development process can be done in a short time. 

Versatility

As a full-stack developer, one has the ability and knowledge in the front-end and back-end making them versatile in any given project and can work in any part of it. 

Comprehensive Understanding

They can also be in a position to understand the overall system as a whole and therefore, it becomes easier to find the problems, make changes to enhance the performance and ensure that the different parts of the application are well linked. 

But on the other hand full-stack development is not without its problems, one of them being the need to constantly update oneself on numerous technologies and tools and practices which are used in both the client side and the server side of the application. A full-stack developer needs to have a general understanding of all layers, and still, be able to deliver efficient applications. 

All in all,full-stack development is the process of development of the application from the standpoint of UI design to the level of servers and databases. Full-stake developers are versatile professional that can be able to involved in the conceiving, building and maintaining of an application that come with full-stack development as standard part of any project in the current software development paradigm.
