Developers have to choose the best backend technology that must meet the project requirements. [NodeJS Vs Python] You’ll find Node.JS useful for many projects as you plan the creation of a web application. However, many web development services require Python. As a result, developers must select the necessary technologies based on the project’s requirements.
If you are unfamiliar with the terms frontend and backend, let’s quickly get to know them.
Frontend – The front end of an application is the portion that you can see, much like the front section of a website that you are browsing. Client-side rendering is another name for it.
Backend – When you visit a web page and click a link to load another web page, the data on that page is rendered from a server and retrieved from a database. The backend is the part of the software that is not visible to you but offers functionality to your application. The backend or server-side rendering makes this possible.
The backend of your program is the most vital component because it gives the necessary functionality. In other terms, the backend offers wings to your applications. And both Node.js and Python have the power to give wings to a digital solution & skyrocket it. So, which to choose?
To overcome this dilemma, let’s compare NodeJs with Python and decide on the best!
Nodejs vs Python: An Introduction
Before comparing, it’s better to get an overview of the two. So what is Node JS? It is a single-threaded, cross-platform, open-source tool for building quick & scalable server-side applications. Ryan Dahl wrote it in 2009. Node.js is the runtime environment for rendering JavaScript outside of the browser.
It is essentially a nonblocking, event-driven I/O approach that gives the project flexibility and exceptional efficiency. It aids programmers in creating distributed, real-time, data-intensive systems.
Applications for Node.js are created using JavaScript, C, and C++. It is compatible with Linux, OS X, and Microsoft Windows. And global companies like LinkedIn, Uber, Walmart, Paypal, Trello, and many more rely on Node.js for their backend.
What about Python? In 1991, Guido Van Rossum released Python’s initial version. It is a multifunctional, object-oriented, high-level programming language. And is regarded as the best language for scripting because of its interpreted nature, dynamic typing, and grammar. It supports many programming paradigms, including OOPS, procedural & functional programming.
Python primarily utilizes Google App Engine. Also, one of its unique advantages is its vast libraries and tools that are maintained by Python web development firms. Python was the third most popular programming language among developers in 2021, according to Statista.
Companies like Google, Spotify, Reddit, Pinterest & more use Python as their backend technology.
NodeJS vs Python: A comparison for the best backend technology
Let’s go deeper and thoroughly explore these server-side languages. Here we’ll also dive into many paradigms to grasp the clear usability of back-end technologies.
Speed
Python: As a server-side language, speed is not its strongest suit. If speed is your first requirement, this single-flow, interpreted language is not the best option. Additionally, Python is not the best choice for programs that perform numerous challenging calculations.
Node JS: Node JS performs admirably because JavaScript code and the V8 engine are used to interpret it. Furthermore, because Node JS runs the code outside the web browser, it works faster and uses fewer resources.
Additionally, Node JS includes an event-non-blocking design to speed up code execution. This architecture also aids in handling numerous queries simultaneously. Also, single-mode caching in Node JS helps to speed up app loading and improve responsiveness.
Scalability
Python: The key attribute that aids in application scaling is multi-threading. But because Python is a server-side language and uses the Global Interpreter Lock, it does not enable multi-threading (GIL). Furthermore, even if Python has several threads, GIL won’t permit the interpreter to carry out tasks concurrently. Thus, affecting the performance of the application as a whole.
Python is also more dynamically typed. As a result, it is inappropriate for huge projects with teams that are changing quickly. It also gets difficult to sustain complex and high-demanding situations as teams increase over time.
NodeJS: Scaling Node JS horizontally and vertically is easy for developers. In contrast to the Python vs. Java debate for microservices, this will enable them to operate and communicate via lightweight techniques.
NodeJS also offers more typing options than Python in terms of programming languages. Developers can use TypeScript that is strongly or weakly typed. Additionally, Node JS allows for additional modules and microservices, enhancing the flexibility of the backend development process.
Error Handling
Python: Because of its clear and compact code, troubleshooting is simpler in this backend language. Additionally, Python is easier to learn than JavaScript and has better parallel processing capabilities due to which debugging is also simpler.
Further, Python provides a better customer experience and helps to increase user retention thanks to its improved error-handling capabilities.
NodeJS: As was previously discussed, Node JS supports multithreading, which improves application performance. But looking back, it also has a drawback. The ability to handle errors decreases as more requests are processed concurrently.
Runtime exceptions are another frequent event that, over time, might be challenging to manage. Therefore, Node JS’s future appears dim in comparison to Python’s in terms of error handling.
Syntax
Python: The language’s simple syntax is frequently regarded as its greatest asset. Python’s syntax does not use curly brackets, therefore developers need to write fewer lines of code.
It will be simpler for the developers to read and debug the code if they use Python for the backend and Flutter for the front end. Furthermore, Python’s code readability is so straightforward that even users without robust technical experience may understand it.
Also, Python becomes the ideal backend language to work on for ambitious developers because of its simpler syntax. So, hire dedicated Python developers to leverage the syntax.
NodeJS: The environment for Node JS is built on JavaScript. Therefore, the developers must have a fundamental understanding of Java. However, because Node JS has a low entry barrier for developers, there is a risk that many inexperienced developers will join. Therefore, it’s important to hire Node JS developers by adhering to the correct advice.
Libraries
Python: Pip, the language’s standard package installer, is responsible for managing libraries & packages. Over 220,000 packages get dispersed throughout numerous categories like image processing, computation, data science & more. Python’s total is likewise astounding.
NodeJS: The packages in Node.js are managed using npm (Node Package Manager). The largest repository of packages in the world, Node Package Manager handles more than 1.3 million items. It also demonstrates how adaptable it is. With a simple search, you can find all the packages on npm.
Range of app development
Python: No matter the size of the backend development project, Python a server-side language can handle anything. Python is used to create 3D games, modeling software, voice and face recognition systems, data processing, and visualization, among other things.
NodeJS: If you’re a business owner considering creating an application that can manage several concurrent requests, you don’t need to look past Node JS. When comparing Node JS with Python, Node can produce complicated single-page applications, hefty client-side rendering applications, and more.
Use Cases
Python: This programming language is used for over 30 years. So it beats out other backend development languages in terms of functionality and concise coding. The language has a huge community and a tonne of documentation. Albeit Python is a little slower than Node JS.
Python has a wide range of applications, including in fields like science and engineering, big data, testing automation, DevOps, technical projects, and more. Additionally, some market leaders like Reddit, Facebook, Pixar, Google, Spotify, and others, support Python and heavily employ it for backend development.
NodeJS: Unlike Python as a server-side language, Node JS development is excellent for apps that require data-intensive or real-time information. Since Node.js’s data streaming efficiency is substantially superior to Python’s, it may also be employed in complex client-side capabilities.
Node JS can be used for many more applications than Python, including chatbots, content management systems (CMS), online businesses, 3D graphics, and gaming. Additionally, tech companies like PayPal, Netflix, Amazon, LinkedIn, and Tumblr choose Node JS.
Community
Python: Python is an old, open-source backend development language. It has a sizable community and numerous contributors with extensive industry expertise. Therefore, a massive developer community can assist the company owner in creating various apps and consulting in challenging situations.
NodeJS: Moreover, Node JS is an open-source platform that has been around for over ten years and is widely used. Similar to Python, Node JS has a large established skilled developers’ community.
The backend development language has rapidly expanded over the past 13 years, giving developers a sizable community to turn to in times of need. As a result, Node JS’s future is very secure in terms of the size of the development community.
