Node.js vs Python – Which Backend Technology is Best to Select for Your Project?

Node.js vs Python – Which Backend Technology is Best to Select for Your Project?

The high-performing, user-friendly, and intuitive applications aligned with the best user experiences bring a plethora of business benefits. Everything which is going on front-end, be it authentication, storing users’ data securely, updating content dynamically, fetching information precisely, and more is powered by the backend behind the scenes.

A single hitch in the backend server impacts millions of the users that are interacting with the app interface. The strong backend development counts on the technology stack used depending on the project needs. However, the presence of a slew of backend technologies such as Python, Node.JS, Ruby, PHP, Java, and Perl confuse the developers as to which backend technology to leverage.

Well, Node.js and Python are trending backend technologies that are used majorly by businesses to meet web functionalities and other requirements. Declaring a winner among the two- python and node.js are not feasible because both languages have their pros and cons. The one-to-one comparison of the two backend technologies is based on certain factors.

What is Node.Js?

It’s a cross-platform, back-end runtime environment that turns JS into a programming language, that makes technology worth cross-platform development. Based on a high-performance V8 engine, Node.js enables faster development by compiling the code straight into machine code.

What is Python?

It’s a high-level, interpreted programming language where code is processed without compilation. It’s packed with universal tools that facilitate web development to advanced mobile app development. The platform-independent language is loved by Python developers as the Python program uniformly runs in any operating system making the development time-inexpensive and cost-efficient.

Which is the best bet to place- Node.Js Vs. Python?

The detailed comparison of python and node.js enable businesses to know which language specifications and tools meet project requirements and demands.

Scalability is a key

  • Building an initial version of the app doesn’t require many resources, which makes python or node.js a good fit for web app development. When the app is scaled with features and functionalities, the resources and tools requirements increase accordingly.
  • Node.js enables building the app with synchronous architecture in one thread. It provides the flexibility to enhance the app without impacting the core source code. With the creation of microservices and modules, skilled developers can scale the app horizontally with seamless nodes addition to existing nodes and vertically with resource addition.
  • Python– the dynamically-typed language suffers from thread issues. It loses the game of scalability to node.js because of no asynchronous architecture. The global interpreter lock does not enable numerous threads to operate simultaneously, which inhibits another process to run before the processes in the queue get finished.

Performance matters a ton

  • When the app’s features are scaled or the interface gets redesigned, the performance should not be degraded. Otherwise, it’s not well-received by the target audience. Node.js and python behave differently when it comes to performance analysis.
  • With non-blocking architecture, the Node.js app runs on the web browser and executes the code outside the website browser making the web app perform at speed. Plus, the single module caching reduces the app’s loading time and improves responsiveness.
  • The absence of multithreading architecture in Python doesn’t allow processes to run parallel which reduces processing speed, which ultimately hurts the app performance.

Set of libraries that backend technologies have

  • Libraries are a collection of various functions, code, and methods that makes app development a breeze. Libraries allow dedicated developers to directly integrate them to build a feature without needing to write code. The framework’s documentation enables experienced developers to use most of the libraries.
  • Node Package Manager (NPM) in node.js has more than 35,000 packages that contain libraries that are well-documented and easy to work with.
  • Python package index manages the python libraries that developers can easily access, learn, and use. Each library includes several modules that are imported at the time they need.

Architecture that improves the performance

  • Architecture defines the set of common principles to follow when working with a programming language or framework.
  • Node.js has a single-threaded architecture with server-side asynchronous programming. In a runtime environment, node.js can handle multiple requests in a single thread that makes input-output functionality remain unblocked. With the feasibility to run parallel processes, the app deployment becomes faster.
  • Python is a little strict in running processes as new processes can’t run unless the former is finished. No support for a multi-threading nature is tackled with some tools that facilitate asynchronous app development that is not completely asynchronous.

Universality is equivalent to accessibility

  • The web application gets maximum success when it’s accessible across all the devices, be it mobile, desktop, tablet, or others. When you hire dedicated developers, they favor backend technologies that meet the high accessibility needs of the projects with platform-independent nature.
  • Node.js is a good fit for both front-end and back-end development. The JS-based language enables mobile app development, web app development, website development, desktop app development, and emerging technology app development.
  • Python is a full-stack programming language that enables the building of various types of app development except for mobile app development. The app created on a Mac through Python will operate on Linux.

Data processing power

  • The apps are generating more data than ever. It makes it essential for web apps to process the data at speed. The programming languages with high data-processing power are preferred.
  • In data-intensive applications, node.js is an ideal choice. The technology provides a runtime environment where frequent requests for data transmission are better handled with parallel I/O operations.
  • On the flip side, the single-threaded nature makes python not a good contender for data processing.

Error handling

  • The error-free coding is imperative to gain impressive success. The backend technologies- node.js vs python that provide the best way to handle errors is highly favored by the expert developers.
  • Node.js developers find it extremely taxing to identify bugs and errors in node.js apps because the processes run parallel.
  • The error screening is a piece of cake in Python because processes run sequentially and have a simple syntax. It edges python ahead of node.js when it comes to error handling.

Node.js vs Python: Which one should you pick?

It’s tricky to declare a winner between the tug of the war of Node.js vs Python. When you have planned to build a full-fledged application with its features outlined, comparing the language performance for individual criteria would help. For instance, if your application needs high data-processing power, improved accessibility, and high performance, then considering to hire Node.js developers for building the app in a runtime environment using Node.js as the backend technology is an optimal solution.

Don’t get overwhelmed with so many options. Come up with your project requirements, then see which backend technology is fulfilling them, and then narrow down the choice to the best one.
