By separating the subject and observers, it is possible to add or remove observers without affecting the subject, or add new subjects without affecting the existing observers. Another benefit of using the Dependency Injection Pattern is that it makes the code more flexible and maintainable. By reducing the coupling between components, it is easier to modify or replace components without affecting the rest of the application. One of the main advantages of using the MVC pattern is that it allows for easy testing and maintenance of the codebase.
Location-Based Social Network App Development
As a backend developer, you’ll need to understand how to organize and request data from databases. Due to its compatibility with artificial intelligence (AI) and machine learning, Python is one of the most popular programming languages. If you’re a full-time backend developer, you do not really need to care about what goes on inside those HTML, CSS and JavaScript files you send to the user’s browser.
How to Choose the Best Backend Framework in 2023
- Version control systems like Git enable effective collaboration and code management.
- Meta also offers training courses on the metaverse to educate people, brands, businesses and professionals on the opportunities it presents and what it means for our world today and into the future.
- To achieve this, backend developers need to design systems that are scalable, reliable, and efficient.
- By regularly profiling your application, you can gain insights into where the most time is spent during execution and identify bottlenecks that could be hindering performance.
- Front-end optimization is all about reducing the amount of time it takes for your web pages to load.
- You’ll learn how to provision for scalability and accommodate the specific requirements of your code.
The Controller retrieves the blog post from the Model component and passes it to the View component, which renders it using a templating engine. Another benefit of using the Decorator Pattern is that it can improve the maintainability of the code. Since the behavior of the object is separated into individual decorators, it is easier to modify or extend the behavior of the object without affecting other parts of the system.
What is Backend Testing? Essential Techniques
Understanding database design, querying, and optimization techniques is vital for efficient data storage, retrieval, and manipulation. Backend development refers to the server side of web applications and services. This involves building and maintaining the core logic, databases, APIs, and server configurations that power the front-end user interface. This feature is very useful, especially in the case of enterprise app development.

These tests focus on small, isolated parts of the application, such as individual functions or classes. The Python standard library includes the unittest module, which provides a framework for creating and running unit tests. Other popular tools for unit testing in Python include pytest and nose, which offer more advanced features and a simpler syntax. Profiling involves analyzing the runtime behavior of your application, often using tools that measure the time and memory usage of your code. Python quality backend in your WEB site provides several profiling tools, such as cProfile for performance profiling and memory_profiler for memory usage analysis.
- Django is often chosen for its “batteries-included” approach, which provides a comprehensive set of tools and features out of the box, such as an ORM, security features, and a templating engine.
- Moreover, Python’s compatibility with various database systems and ORMs (Object-Relational Mapping) allows developers to optimize database interactions.
- Google pays extra attention to your website’s server-side development, and continuously monitors the response time for different pages on your website.
- They prevent dangling references and ensure memory safety, a critical aspect of writing secure and reliable backend code.
- As per the GitHub data, Gin Gonic – a Go framework has around 128k+ dependents and has received 68k+ stars.
Testing and Quality Assurance of Python Backends
One of the key trends in backend development is the rise of serverless architecture. Serverless computing allows developers to focus on writing code without worrying about server management or scalability. It offers benefits like reduced costs, increased scalability, and faster development cycles. Testing frameworks like Jest, PHPUnit, and Pytest provide tools for writing and running automated tests.
When people learn by themselves, they usually do not have a team or anyone who can do front end development. So you’ll often have to create webpages and servers all by yourself, at least in the beginning. Well, going by the books, you may say that a person who codes an application that can respond to HTTP requests is a back end developer. Back end development, as mentioned above, involves the programming of a computer sitting probably on the other side of the planet responsible for responding to what your users say from their own computers.
