Tech Stack Components


To refresh your memory, a technology stack consists of two components—thefrontend and backend stacks. These stacks also shape the role of the developerwho builds the product.

Frontend Tech Stack


The frontend tech stack is the client’s side of the application. Client-siderefers to anything that a user can see or engage with on a screen. The mainconcern of the frontend stack is to create a stellar user experience, smoothuser interface, and straightforward internal structures. In other words, it isresponsible for the design, format, and navigation of websites or web apps.There are two principal elements of a frontend stack. These are: * HTML (Hypertext Markup Language) – it’s a markup language for creating and displaying electronic documents (web pages). They are the backbone in the organization and placement of content on a web page. * CSS (Cascading Style Sheets) – It is responsible for the format and layout of the web pages. It includes the font styles, sizes, layout, color, and other aspects of a web page.To make web pages interactive, you use JavaScript. It’s a programming languagethat allows you to implement dynamic features on web pages; through itslibraries (React, jQuery, and Ember) and frameworks (Angular.js, Ember.js,Vue.js).VIDEO

Backend Tech Stack


The server-side of software development is the backend tech stack. It refersto the inner workings of a website or app that users cannot see. Think of itlike the electric power stations that generate electricity for your home. Theymay seem invisible in the background, but they are important to keep theoperations running smoothly.The backend stack includes these elements: * Programming languages – This creates logic for apps and websites. The codes link the web to a database. Some examples are JavaScript, PHP, and Python * Frameworks – it provides support of applications based on a single programming language. Laravel, Django, and Ruby on Rails are few of the popular frameworks * Servers – You need backend servers to manage client requests. Apache, Nginx, and Microsoft’s Internet Information Server (IIS) are great examples of web servers. * Databases – It’s a digital space to store data (word document, web page, MP3 file). MongoDB, PostgreSQL, and MySQL are common databases.These web development programming languages, frameworks, technologies,servers, databases are built on top of each other. Hence, the term techstacks.VIDEO

Top Tech Stack Models


To save you time and money, you can use proven tech stack models. Theircomponents are regularly updated but its principles are the same. One of theadvantages of using these popular tech stack examples is the availableknowledge base.Here are the top tech stacks to consider:

Web developer roles to play in tech


All websites we use today are essentially two parts: the frontend and thebackend. Both are equally important to build a fully functional website.So, what is the difference between frontend and backend?The frontend is what we see and interact with and the backend is the brainbehind it. To understand this better, let’s take Netflix for example.Frontend of Netflix Once we login, we get to scroll through an endless list of TV shows andmovies. The elements that are visible to us such as the programs, the detailswe get to read before making our choice, the option to include captions,adjust the volume, etc, ensure a smooth and user-friendly experience.Backend of Netflix As soon as you log in, the backend fetches data from the database server anddisplays personalized recommendations based on your interests and previousbehavior. Backend developers code the logic for such actions and play anintegral role in implementing the functionality of the product.It is clear that both the frontend and backend come together in building afully functional website.But can a web developer do both?Full stack web developers are the complete package with knowledge in bothfrontend and backend development.For this, you must have proficient knowledge in a sought after tech stackssuch MEAN, MERN, LAMP, etc.MEAN: MongoDB, Express.js, AngularJS (or Angular), and Node.jsMERN: MongoDB, Express, React, NodeLAMP: Linux, Apache, MySQL, and PHPMERN stack is becoming increasingly popular and is a highly recommended techstack for those looking to pick up Java full stack developer skills.* * *Every aspiring web developer faces the dilemma of being a frontend developeror backend developer. This can be simplified through an analogy. Would youlike to be the actor of an oscar winning film or the director?Both play their parts in entertaining the audience. The actor brings a storyto life, which is what we see on screen. Whereas it is the director, behindthe camera, creating the story.If you are a logical thinker, passionate about coding, and don’t mind workingbehind the scenes to create impactful solutions, backend development is madejust for you.

What does a backend developer do?


Backend developers are in charge of the proper functioning of a webapplication. They write logical code to implement the functionality andenhance the speed and efficiency of a web app.This means that a backend developer is responsible for: 1. Implementation of the backend web architecture that comprises servers, databases, operating systems. 2. Handling client requests with APIs. 3. Managing database(s) and caching. 4. Creating the business logic to run the application. 5. Troubleshooting performance bottlenecks using scientific debugging. 6. Build reusable code and libraries for future use. 7. Optimizing functionality, page loading speed, and scalability of the application. 8. Improving site infrastructure with timely enhancements and upgrades.

Pro tips, from one developer to another


1. Don’t wait till you learn enough theory before starting a project. 2. Leverage GitHub to learn more from other developers. Study their code and analyze how they went about solving technical challenges similar to your case. 3. Be patient with yourself. Bugs in your code make you a better problem solver. Use scientific debugging principles to narrow down your challenges. 4. Go through what other developers have to say in forums like Stackoverflow.

What is a web framework?


A high-functioning and multifaceted web applications are essential to businessand online e-commerce. The development of web applications is a time-consumingprocess requiring a technical skillset and aptitude; however, the use of WebDevelopment Frameworks greatly facilitates the process. Defined simply, a webapplication framework is a software that aids in the development of webapplications and services. With the correct knowledge and skills, webframeworks can be highly customizable allowing for the input of uniquefeatures and tools.There are a variety of different frameworks for web development. The below webframeworks list summarizes two prominent types front-end web frameworks andbackend web frameworks.

Frontend Web Frameworks


In the parlance of web applications, the frontend refers to the area of thesite or application with which visitors interact directly. In the past, coderswere required to manually create code to dictate these interactions andbehaviors. Frontend web frameworks reduce the complexity of this task byproviding pre-written coding that developers may build on.

Backend Web Frameworks


Also known as server-sided frameworks, backend web frameworks also assist withthe development of web applications. However, while other frameworks dealprimarily with the visor facing side of web applications, backend webframeworks provide tools that assist with the development of web tasks such assecurity, user authorization, database interaction, and URL routing. Please continue reading for an in-depth list of the most commonly used webframeworks available today.
