Welcome to this ProfileTree video.
In this video, we look at the back-end development process of web development of a website and how you can use this for your own website.
Back-end web development refers to server-side development. It focuses on how the website works, including the core computational logic powering the website, data management, and server configuration. While the front-end development involves what users see on their screens (the user interface), the back-end is all about making sure everything runs smoothly behind the scenes.
Key components of back-end web development include:
Server: This is the computer where your website lives. It's the back-end developer's job to set up and manage this server, which involves selecting the hardware and operating system, handling upgrades and backups, monitoring performance, and handling requests from the front-end.
Application/Server-side Code: This is the code that runs on the server, typically written in a server-side language like Python, Ruby, Java, PHP, Node.js, etc. This code contains the logic of the application and handles tasks like user authentication, data processing, and routing URLs to the correct destination.
Database: Almost all web applications use a database to store data like user information, content, and system settings. Back-end developers need to be proficient in database technologies like SQL (MySQL, PostgreSQL, etc.) or NoSQL (MongoDB, Couchbase, etc.) to store, retrieve, and manipulate data.
APIs (Application Programming Interfaces): APIs are how different software applications communicate with each other. For example, if your website has a feature that pulls in Tweets from Twitter, it's likely using Twitter's API to do this. Back-end developers design, develop, and manage APIs to ensure seamless data flow between different parts of the system.
Server-Side Frameworks and Libraries: Frameworks (like Django for Python, Express.js for Node.js, Laravel for PHP) provide pre-written code for common tasks, allowing developers to build applications faster and more securely. Libraries are collections of pre-written code snippets that can be used and reused to speed up coding.
Version Control Systems (VCS): Version control systems like Git help manage changes to a project's codebase. They keep track of all changes made to the code, who made them, and why, allowing developers to collaborate effectively and to revert changes if something goes wrong.
Security: This involves protecting the website from threats and attacks, handling sensitive data securely, and maintaining user privacy.
A full-stack developer is someone who is comfortable working with both front-end and back-end technologies. They understand how the web works at every level, from the server to the browser.
