Today, the number of technologies used in the web may confuse anybody who doesn’t have enough web app development expertise. Every project has a unique set of specifications and requirements. When it’s time to build an application, developers have to choose the right combination of technologies to ensure the best possible result. The back-end is the part of a web application that is “hidden” from the user’s eyes. Nonetheless, everything that happens on the server-side powers the user-facing side of the web application, ensuring its trouble-free functionality.
Today, we’ll take a look at Node.js and Python, two of the most popular backend related technologies at the moment. We’ll learn about their strong and weak sides, which will help you make a more educated decision when choosing a particular technology for your project.
First of all, it’s important to understand that programming languages and frameworks are initially designed to perform a set of specific tasks. That’s why the strategy of choosing the most popular technologies or those that were used in successful projects, in most scenarios, won’t be the wiser one. When you decide, you should consider the following aspects of your future web application:
- Type of application. It may be a business app, a mobile game, or a CRM solution. For each of these cases, software development companies use a specific set of tools;
- Application geography. Different development tools are utilized for apps built to be used within an organization and those that supposed to provide users with access from all around the world;
- Budget, as you can suggest, also plays its role. In some cases, app development requires the involvement of a broader range of specialists, which, in turn, will increase your costs on their salaries.
As you understand, the list includes only a couple of examples of how different app requirements can affect the stack of technologies used during development. What you have to remember is that it’s essential to consider every feature of your future app when you decide to cooperate with a company that provides web app development services. Now, we’d like to shed some light on technologies that may become the building blocks of your future web application.
Python. Great Extensibility and the Ease of Use at the Expense of Performance and Scalability
Python is not something new. This programming language appeared in the early ’90s and remains one of the most popular, innovative, and flexible technologies at the moment. Constantly developing Python libraries, comprehensive documentation, and extensive community explain high interest among developers worldwide. Besides, Python is excellent for such a wide range of tasks as scientific computing, data science, machine learning, and AI.
Let’s talk about scaling possibilities. Python uses Global Interpreter Lock, which doesn’t support multithreading required to scale a web app. Developers can use various libraries that can enable multithreading functionality, but this Python feature is not enough to consider Python-based apps “naturally” multithreading. The inner architecture of this technology doesn’t allow running multiple tasks simultaneously, which can negatively affect performance. Besides, Python is dynamically-typed, which doesn’t allow the efficient maintenance of growing development teams.
What’s good about Python is that there’s no shortage of extensibility options. Since its first appearance in the ’90s and during the further years, tons of development tools have been created. For example, with zero effort, Python developers can use the full power of Django, Flask, web2py, and more of full-stack tools.
Let’s be honest. Developers do not always write every line of code themselves during project development. Sometimes it’s better to rely on someone else’s experience instead of reinventing the wheel. That’s when the community becomes important. Python is older than Node and is also an open-source technology. The user community includes an immense number of contributors with different expertise. Both business owners and Python developers can benefit from access to such sources of knowledge.
Node.JS. Excellent Performance If CPU-intensive Tasks in Not One of Your Priorities
The first thing to mention is that, unlike Python, Node can provide remarkable performance since it is interpreted with the V8 engine in which Google invests heavily. Node executes code outside the web browser which allows building resource-efficient apps with excellent performance. Also, the event-driven non-blocking architecture of Node allows processing several requests at the same time, which also gives a boost to the overall performance.
Developers don’t have to create a large monolithic core and can build a set of microservices and modules instead. Each of them can communicate with a lightweight mechanism running its own process. The ease of adding extra microservices and modules make the app development process more flexible. All these features allow scaling apps effortlessly, especially compared to Python-based projects.
Node is a relatively young technology, especially compared to Python. Nevertheless, it has a large and active contributing community. Web developers from all over the world have grown to love this technology and are always happy to share their knowledge. For business owners, it means that there’s always the possibility to find specialists with enough expertise for Node app development and further maintenance. Developers can also benefit from the large community since they can always rely on peer support.
When it comes to comparing different web development technologies, there’s no better conclusion that “there are no one-size-fits-all solutions.” Intentionally, developers create tools that will help them solve a specific range of tasks. In the “Python vs. Node” battle, none of the technologies beats the other. Each web app has its own requirements, and developers should choose a particular set of tools based on these needs. Python is used more in the entire web, and such popularity is fully deserved. Node, on the other hand, has such advantages as high scalability and better performance.
