Node.js VS Python: Which Backend Technology Should You Choose?

Node. Js:

Node.js is the best backend technology for building high scalable complex applications. The event-driven model and non-blocking I/O enable the server to process requests flawlessly. Node.js supports microservices that are very scalable and run processes dynamically. You can easily add extra modules for existing nodes horizontally and resources vertically for scaling. It makes the development process more flexible.

Python:

Python is not effective in handling multi-threads which is a drawback. We can not run threads simultaneously because the technology is built on Global Interpreter Lock (GIL). The coding language of Python is not suitable for large-scale applications. So, Python lags behind Node.js when you consider scalability.

Node. Js:

This server-side architecture of Node.js uses Single Thread Event Loops that handle multiple requests from the clients. A single thread is sufficient to handle blocking incoming requests instead of creating multiple threads. It also requires fewer resources and memory as the requests are processed one at a time. All these benefits make Node.js faster and responsive than other server development technologies.

Python:

The Python architecture has no inbuilt asynchronous programming to support input-output functionality. We can not run other unblocking requests when a blocking request is still in process. It requires special modules to enable this feature which is not available in most python frameworks. So, the event-driven architecture in Node.js is more effective than the python backend technology.

Node. Js:

The syntax of the Node.js programming language is similar to the browser JavaScript. If you have JavaScript knowledge previously, then writing backend code for your application using Node.js is an easy task.

Python:

The developers need to write only a few lines of code to design the module compared with Node.js. Python syntax is easy to remember as the language is similar to English. Clients with minimum knowledge of any programming language can understand the code.

Node. Js:

The NPM (Node Package Manager ) contains libraries and packages in the Node.js technology. It is one of the largest open-source libraries in the world. You can easily pull in packages of existing code, and these are configurable for a wide range of use cases.

Python:

The default package installer of Python is pip which is Python Package Index(PyPI). It has 220 thousand packages for different categories like image processing, data science, calculation, and more to choose from according to needs. Though Python has several libraries, the documentation makes deployment easy and a favorite among developers.

Node. Js:

The program execution outside the web browser will make your mobile application a better performer. It allows you to use the TCP sockets feature, which is not valid to use in the browser. We also know that Node.js has event-driven non-blocking architecture that processes requests fast.

Python:

The single thread architecture in python language makes the responsive process slow. It is a considerable drawback for the application to get data from the server. So, when you compare Node.js vs python for performance and speed, Node.js takes the upper hand.

Node. Js:

Node.js can handle websites and web applications on different devices. It is because we can use JavaScript in both the frontend and backend development processes. The cross-platform functionality makes the app developers prefer Node.js for mobile application development.

Python:

Python is preferable for IoT solutions, cloud-based, and AI solutions. The cross-platform features help you to run the same desktop app in Linux, Windows, and Mac. In this Python and Node.js stand at the same level.

Node.js

Node.js has more extensibility with frameworks, customization, and integration with various tools. A new framework or tool is introduced in the Node.js technology regularly.

• Frontend Development Framework- Babel
• Unit-Based Testing- Jasmine
• Project Management Framework- Log.io
• Module Binding- Webpack

Python

The huge number of frameworks in Python is the reason for a high rate of extensibility.

• Web Development- Flask
• Backend Development Framework-Django
• Automated Testing- Robot

Node.js

Despite being a new technology in the field, Node.js has amazing followers forming a wide community. As a developing company, you can find many talented app developers across the world to hire.

Python

It is the oldest programming language and has a larger community than others. The overall development of language is because of the active participation of the developers.

Node.js

The Node.js technology uses error object, try-catch exceptions, call stack techniques to handle the errors.

Python

You can find three types of errors in the python programming language, which are syntax errors, logic errors, and exceptions. The process of finding and rectifying these bugs is not time-consuming in Python, unlike other backend technologies.

Node.js

The event-based architecture of Node.js makes it the best choice for mobile app development for IoT solutions, messaging applications, chatbots for websites, streaming app, and real-time collaboration services. This technology can handle frequent client requests with fast response.

Python

You can use this technology for developing apps based on image processing, machine learning systems, 3D games, data analysis, voice and face recognition. So, you can choose the backend technology for your mobile app development depending upon the usage of the application.
