Git & GitHub

• Git: A version control system that helps developers track changes to code over time, enabling you to manage your project efficiently.
• GitHub: A platform for hosting your Git repositories, collaborating with others, and contributing to open-source projects. It’s widely used by developers to work together on code and share progress.

GitHub Actions

Automating workflows is a trending practice in modern development. GitHub Actions allow you to automate tasks like testing, building, and deploying code whenever you push changes to your repository.

Best Practices

When using Git and GitHub, ensure you:

• Write clear and meaningful commit messages.
• Make use of branching to work on new features without disrupting the main project.
• Contribute to open-source projects to gain experience and build a network in the developer community.

Step 3: Back-End Development – The Server Side

The back-end of an application deals with the server, database, and application logic that users don’t see but interact with indirectly.

Languages & Frameworks

• Node.js: A runtime environment that allows you to run JavaScript on the server side. Paired with the Express.js framework, Node.js is an excellent choice for building fast and scalable applications.
• Python with Django: Django is a high-level Python framework known for its simplicity and clean code structure, perfect for developers looking for a more straightforward entry into back-end development.
• Ruby on Rails: A popular framework known for its emphasis on convention over configuration, helping developers build applications quickly.
• PHP with Laravel: Laravel is a PHP framework that simplifies complex tasks like routing, authentication, and session management.

Databases

Understanding databases is a core skill for any full-stack developer.

• SQL Databases: Examples include MySQL and PostgreSQL, which are relational databases that store data in tables.
• NoSQL Databases: Examples include MongoDB, which store data in flexible, JSON-like documents.

APIs

An API (Application Programming Interface) allows your application to communicate with other systems.

• REST: A common API design that uses HTTP requests for communication.
• GraphQL: A modern alternative to REST, allowing clients to request only the data they need.

Trending Topics

• Serverless Architecture: Serverless computing abstracts the underlying infrastructure, allowing developers to focus solely on writing code. Platforms like AWS Lambda and Azure Functions let you deploy server-side logic without managing servers.
• Cloud Functions: These are functions that run in the cloud without the need for managing the underlying infrastructure. Popular cloud providers offer these services for scaling and deploying code easily.

Step 4: Learn About Databases and Data Storage

Mastering databases is essential for building robust web applications. Understanding the differences between relational (SQL) and non-relational (NoSQL) databases will help you choose the right solution for your projects.

• Relational Databases (SQL): Use structured query language (SQL) to manage data stored in tables. Examples: MySQL, PostgreSQL.
• Non-Relational Databases (NoSQL): Store data in more flexible formats like documents, graphs, or key-value pairs. Example: MongoDB.

Basic CRUD Operations

Learn how to:

• Create, Read, Update, and Delete data in your chosen database.
• Design effective database schemas to organize data efficiently.

Step 5: DevOps Basics – Deployment and Hosting

Understanding deployment and hosting will help you ensure that your applications are live and accessible to users.
