1. Programming basics
First of all, as a backend developer, you need to master at least one programming language. Python is a great choice because it is easy to learn and powerful. Let's start with a simple example, printing "Hello, World!" to the console.
2. Learn the basics of the Web
Understanding the basics of web development is a prerequisite for back-end development. Learn HTML, CSS and JavaScript, build simple static web pages, and understand how the front-end and back-end interact.
3. Learn back-end programming languages
Master a backend programming language such as Node.js (JavaScript backend), Python, Java, or Ruby. Choose one of these languages and learn its syntax, data structures, and object-oriented programming.
4. Databases and SQL
Learn the basic concepts of database and SQL language, and understand the storage and management of data. Try creating a simple database table and query the data using SQL statements.
5. Server and API
Learn how to set up a simple web server and create an API (application programming interface) to handle HTTP requests. Write code in a back-end language to handle user requests and return corresponding data.
6. Frameworks and Libraries
Learn to use backend frameworks and libraries to speed up the development process. For example, for Python, you can learn to use the Django or Flask frameworks. For JavaScript, you can learn to use the Express framework.
7. Security
Learn about common security vulnerabilities in web applications, such as cross-site scripting (XSS), cross-site request forgery (CSRF), and more, and learn how to protect your application from attacks.
8. Deployment
Learn how to deploy your backend application to a server and make it accessible on the public network. Deploy using a cloud service such as AWS or Heroku.
9. Continuous learning
Backend development is an ever-evolving field, and continuous learning is the key to success. Follow the latest technology trends and best practices in the industry and continually improve your skills.
The purpose of the routines is to give you a simple understanding of back-end development. During the actual learning process, you may encounter more complex concepts and techniques. Follow this introductory tutorial to learn more and apply what you learn in real-world projects. I wish you success in your learning journey of backend development!
