Skills
Building a web application requires a diverse range of skills. In this article, we will outline the essential skills needed to create a fully functional web application, specifically a Single Page Application (SPA), using modern frameworks. Whether you're a newbie or an aspiring web developer, acquiring these skills will set you on the right path to becoming proficient in web application development.
NOTE
Sections below are not prioritized in any way and should be read as equally important.
Computer Literacy
First and foremost, having a good level of computer literacy is essential. Familiarize yourself with basic computer operations, file management, and internet usage. This foundation will enable you to comfortably work with computers and leverage the internet to enhance your development process.
Software Architecture
Understanding software architecture is crucial for building web applications. Learn about the client-server model, different layers in software architecture, and the concept of networks. Gain knowledge of how the server and client communicate and the roles they play in delivering a functional application.

Internet Protocols
Familiarize yourself with fundamental internet protocols that underpin web communication. These include the Hypertext Transfer Protocol (HTTP) for transmitting data across the web and the Secure Sockets Layer (SSL) for ensuring secure communication.
HTML
HyperText Markup Language (HTML) is the backbone of any web application. Learn HTML to create the structure and content of web pages. Gain proficiency in using HTML tags, attributes, and elements to represent the various components of your application.
CSS
Cascading Style Sheet (CSS) is essential for styling and visually enhancing your web application. Understand CSS selectors, properties, and values to control the layout, colors, typography, and other visual aspects of your application.
JavaScript
JavaScript is a scripting language that brings interactivity and dynamic behavior to web applications. Learn JavaScript to handle user interactions, manipulate HTML and CSS, and perform client-side computations. Gain knowledge of core JavaScript concepts, such as variables, functions, arrays, and objects.
TypeScript
TypeScript is a superset of JavaScript that introduces static typing and additional features. While not mandatory, learning TypeScript can enhance your development process, as it provides improved code organization, type safety, and tooling support.
SQL
Structured Query Language (SQL) is essential for interacting with databases. Learn SQL to perform operations such as data retrieval, insertion, modification, and deletion. Understand database concepts like tables, relationships, and queries to effectively work with data in your web application.
NoSQL
In addition to SQL, familiarize yourself with NoSQL databases. NoSQL databases, such as document-oriented databases, offer flexibility and scalability for handling large amounts of data in web applications. Learn about document storage and indexing in NoSQL databases to choose the appropriate database solution for your application.
Caching
Understanding caching concepts is crucial for optimizing web application performance. Explore cache solutions like Redis, which can store frequently accessed data in memory, reducing the need for expensive database queries.
Web Server Configuration
Gain knowledge of web server configuration to deploy your web application successfully. Learn about popular web servers like Apache and NGINX, along with their configuration settings. Understand how to set up virtual hosts, handle SSL certificates, and optimize server performance.
Security Concepts
Web application security is of paramount importance. Familiarize yourself with the concepts outlined by the Open Web Application Security Project (OWASP), which provides guidelines for securing web applications. Learn about common security vulnerabilities and best practices for mitigating them.
Software Design
Translating business requirements into working software requires strong software design skills. Learn about software design principles, patterns, and architectural styles. Gain knowledge of how to design modular, maintainable, and scalable web applications.
Unit Tests
Unit testing is crucial for ensuring the correctness of your code. Learn how to write unit tests to verify individual units of your application, such as functions or modules. Understand testing frameworks and tools that aid in automating the testing process.
End-to-End (e2e) Tests
End-to-End (e2e) testing verifies the flow and functionality of your web application from start to finish. Learn how to write e2e tests to simulate user interactions and validate the behavior of your application as a whole. Explore testing frameworks and tools specifically designed for e2e testing.
SEO (Search Engine Optimization)
Understanding the basics of Search Engine Optimization (SEO) is beneficial for ensuring your web application can be discovered by search engines. Learn about techniques to improve your application's visibility in search engine results, such as optimizing meta tags, URL structure, and content.
Front-End Frameworks
Modern front-end frameworks provide powerful tools and abstractions for building web applications. Familiarize yourself with popular frameworks like React, Angular, Vue.js, or Svelte. Learn the core concepts, components, and workflows of your chosen framework to efficiently build robust SPAs.

Version Control
Knowledge of version control systems like Git is crucial for managing code changes, collaborating with a team, and maintaining the history of your project.
Package Managers
Familiarity with package managers like npm or Yarn allows you to install, manage, and update dependencies in your web application effortlessly.
Choosing the right package manager
Build Tools
Understanding build tools like Vite helps automate tasks such as bundling JavaScript, optimizing assets, and managing code transliteration for improved performance.

Debugging and Troubleshooting
Developing skills in debugging and troubleshooting common issues helps you identify and resolve errors efficiently during the development process.
Software Engineering - Debugging
Deployment automation
Building and delivering changes can be too time-consuming if done manually. Continuous integration, delivery and deployment - CI/CD is a method to frequently deliver apps to customers by introducing automation into the stages of app development.
Containers
A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.
