Python vs Node.js – Which One to Choose in 2023?

How to Choose Between Python and Node.js

Python and Node.js are both popular programming languages that can be used to create web applications, with each being more suitable for certain types of projects. Many users choose to use one or the other, but what should they choose in 2023? It depends. With both languages being powerful and with technologies quickly changing, the choice ultimately comes down to your skill level, the project’s complexity, and budget.

What is Python?

Python is a popular general-purpose computer language with a wide variety of uses. It offers high-level data structures, dynamic type, dynamic binding, and many other features that make it ideal for complex program development and “glue code” that connects components. It can also run C or C++ applications and make system calls to practically any operating system. Python is a popular programming language due to its versatility and ability to operate on almost any system architecture.

What is Node.js?

Node.js is a JavaScript-based framework that may be used to create online chat applications, video streaming websites, single-page applications, and various other I/O-intensive web applications and web apps. It’s built on Google Chrome’s JavaScript V8 Engine and is utilized by both vast corporations and young businesses (Netflix, Paypal, NASA, and Walmart, to name a few).

Thousands of developers use Node.js because it is open-source and entirely free. It has several benefits over other server-side technologies like Java or PHP, making it a preferable option.

Comparing Python and Node.js

If you’re a developer, you’ll know that there are many options when it comes to choosing a language to write your code in. Node.js and Python are two of the most popular choices for developers—and a good reason.

Both Python and Node.js are powerful web development environments with a lot of potential for large and small-scale projects. Python and Node.js have their differences, of course, and choosing the right one for your project is all about knowing what makes each unique—and what you’ll need to create the project you have in mind.

Architecture

There are a few similarities between Python and Node.js regarding development architecture. Both utilize event-driven, non-blocking I/O (input/output) calls. This means that the programming language can handle multiple requests at once without the need to wait for previous requests to finish up.

This parallelism allows developers to complete tasks more efficiently while freeing up server resources that other processes would have used in earlier web development languages.

Python is also less resource-intensive than Node.js. The setup takes quicker and simpler since less space and resources are utilized. Node.js, on the other hand, requires more resources and takes longer to set up than Python.

Libraries

Libraries are responsible for the rapid advancement of app development technologies in recent decades. The Node Package Manager manages a large number of well-documented libraries in Node.js. NPM is the world’s biggest package repository, with over 350,000 packages.

Pip, which stands for ‘Pip Installs Packages,’ manages Python’s libraries. Python libraries are well-documented and simple to deploy, according to industry standards. This is often true, but not in the case of new libraries. New technologies are often less thoroughly documented than older technologies, making newer libraries less dependable.

With both technologies, you’ll have many alternatives for libraries and ancillary-development tools. Both are equally effective!

Error Handling

Nothing beats the feeling of writing error-free code. As a result, CTOs will always choose the language with the best error-handling methods. Finding faults and problems in the code might be time-consuming using Node.js’ parallel-processing functionality.

Python’s simpler syntax, low-code interface, and absence of concurrent processes help when looking for problems and mistakes in the code. As such, it makes it popular within the small business demographic..

If error handling is a critical factor in your selection, you may have already deduced that Python has a considerable advantage over Node.js.

Data Processing

This may seem to be a minor factor, but it is important. A language/environment with higher data processing capability is naturally more efficient and adaptable.

If your app’s use case requires a lot of data, Node.js should be your first pick. The runtime environment’s technology makes it excellent for programs where data is often transferred and managed. Python is sluggish in processing data because it has a basic syntax and just one thread running at a time.

Node.js is the more efficient competitor because of its parallel processing and smooth I/O operations.

Conclusion

As you can see, both languages are impressive and have numerous advantages. Developing an app in either of them is a wise choice, depending on the needs of your business. Both are easy to learn for experienced developers—but much more difficult for newbies.

Node.js is more versatile and has more development resources than Python did in 2011. It has one distinct advantage: it runs on JavaScript, the most popular programming language worldwide and most developers’ primary language. This makes Node.js accessible to a larger number of developers: not just Java and C++ users but also Python and JavaScript users.

This makes Node.js a valuable development tool for companies that need to reach a wide audience. Browse application of Python and Node.js development to find more information.

Exploring Forms in Angular – Types, Benefits and Differences

While developing a web application, or setting dynamic pages and meta tags we need to deal with multiple input elements and value types, such limitations could seriously hinder our work – in terms of either data flow control, data validation, or user experience.

This article is an excerpt from the book, ASP.NET Core 5 and Angular, Fourth Edition by Valerio De Sanctis – A revised edition of a bestseller that includes coverage of the Angular routing module, expanded discussion on the Angular CLI, and detailed instructions for deploying apps on Azure, as well as both Windows and Linux.

Sure, we could easily work around most of the issues by implementing some custom methods within our form-based components we could throw some errors such as isValid(), isNumber(), and so on here and there, and then hook them up to our template syntax and show/hide the validation messages with the help of structural directives such as *ngIf, *ngFor, and the like. However, it would be a horrible way to address our problem; we didn’t choose a feature-rich client-side framework such as Angular to work that way.

Luckily enough, we have no reason to do that since Angular provides us with a couple of alternative strategies to deal with these common form-related scenarios:

  • Template-Driven Forms
  • Model-Driven Forms, also known as Reactive Forms

Both are highly coupled with the framework and thus extremely viable; they both belong to the @angular/forms library and share a common set of form control classes. However, they also have their own specific sets of features, along with their pros and cons, which could ultimately lead to us choosing one of them.

Let’s try to quickly summarize these differences.

Template-Driven Forms

If you’ve come from AngularJS, there’s a high chance that the Template-Driven approach will ring a bell or two. As the name implies, Template-Driven Forms host most of the logic in the template code; working with a Template-Driven Form means:

  • Building the form in the .html template file
  • Binding data to the various input fields using ngModel instance
  • Using a dedicated ngForm object related to the whole form and containing all the inputs, with each being accessible through their name.

These things need to be done to perform the required validity checks. To understand this, here’s what a Template-Driven Form looks like:

<form novalidate autocomplete="off" #form="ngForm"
(ngSubmit)="onSubmit(form)">

<input type="text" name="name" value="" required  
placeholder="Insert the city name..."   
[(ngModel)]="city.Name" #title="ngModel"  
/> 

<span *ngIf="(name.touched || name.dirty) &&   
   name.errors?.required">  
        Name is a required field: please enter a valid city name.  
</span> 

<button type="submit" name="btnSubmit"   
      [disabled]="form.invalid">  
      Submit  
</button>
</form>

Here, we can access any element, including the form itself, with some convenient aliases – the attributes with the # sign – and check for their current states to create our own validation workflow.

These states are provided by the framework and will change in real-time, depending on various things: touched, for example, becomes True when the control has been visited at least once; dirty, which is the opposite of pristine, means that the control value has changed, and so on. We used both touched and dirty in the preceding example because we want our validation message to only be shown if the user moves their focus to the <input name=”name”> and then goes away, leaving it blank by either deleting its value or not setting it.

These are Template-Driven Forms in a nutshell; now that we’ve had an overall look at them, let’s try to summarize the pros and cons of this approach. Here are the main advantages of Template-Driven Forms:

  • Template-Driven Forms are very easy to write. We can recycle most of our HTML knowledge (assuming that we have any). On top of that, if we come from AngularJS, we already know how well we can make them work once we’ve mastered the technique.
  • They are rather easy to read and understand, at least from an HTML point of view; we have a plain, understandable HTML structure containing all the input fields and validators, one after another. Each element will have a name, a two-way binding with the underlying ngModel, and (possibly) Template-Driven logic built upon aliases that have been hooked to other elements that we can also see, or to the form itself.

Here are their weaknesses:

  • Template-Driven Forms require a lot of HTML code, which can be rather difficult to maintain and is generally more error-prone than pure TypeScript.
  • For the same reason, these forms cannot be unit tested. We have no way to test their validators or to ensure that the logic we implemented will work, other than running an end-to-end test with our browser, which is hardly ideal for complex forms.
  • Their readability will quickly drop as we add more and more validators and input tags. Keeping all their logic within the template might be fine for small forms, but it does not scale well when dealing with complex data items.

Ultimately, we can say that Template-Driven Forms might be the way to go when we need to build small forms with simple data validation rules, where we can benefit more from their simplicity. On top of that, they are quite like the typical HTML code we’re already used to (assuming that we do have a plain HTML development background); we just need to learn how to decorate the standard <form> and <input> elements with aliases and throw in some validators handled by structural directives such as the ones we’ve already seen, and we’ll be set in (almost) no time.

For additional information on Template-Driven Forms, we highly recommend that you read the official Angular documentation at: https://angular.io/guide/forms 

That being said; the lack of unit testing, the HTML code bloat that they will eventually produce, and the scaling difficulties will eventually lead us toward an alternative approach for any non-trivial form.

Model-Driven/Reactive Forms

The Model-Driven approach was specifically added in Angular 2+ to address the known limitations of Template-Driven Forms. The forms that are implemented with this alternative method are known as Model-Driven Forms or Reactive Forms, which are the exact same thing.

The main difference here is that (almost) nothing happens in the template, which acts as a mere reference to a more complex TypeScript object that gets defined, instantiated, and configured programmatically within the component class: the form model.

To understand the overall concept, let’s try to rewrite the previous form in a Model-Driven/Reactive way (the relevant parts are highlighted). The outcome of doing this is as follows:

<form [formGroup]="form" (ngSubmit)="onSubmit()"> 

<input formControlName="name" required /> 

<span *ngIf="(form.get('name').touched || form.get('name').dirty)           
&& form.get('name').errors?.required">          
Name is a required field: please enter a valid city name.  
</span> 

<button type="submit" name="btnSubmit"          
[disabled]="form.invalid"> 
Submit 
</button>  
 
</form>

As we can see, the amount of required code is much lower.  Here’s the underlying form model that we will define in the component class file (the relevant parts are highlighted in the following code):

import { FormGroup, FormControl } from '@angular/forms'; 

class ModelFormComponent implements OnInit {  
form: FormGroup;   
     ngOnInit() {  
    this.form = new FormGroup({  
       title: new FormControl()  
    });  
  }  
}

Let’s try to understand what’s happening here:

  • The form property is an instance of FormGroup and represents the form itself.
  • FormGroup, as the name suggests, is a container of form controls sharing the same purpose. As we can see, the form itself acts as a FormGroup, which means that we can nest FormGroup objects inside other FormGroup objects (we didn’t do that in our sample, though).
  • Each data input element in the form template – in the preceding code, name – is represented by an instance of FormControl.
  • Each FormControl instance encapsulates the related control’s current state, such as valid, invalid, touched, and dirty, including its actual value.
  • Each FormGroup instance encapsulates the state of each child control, meaning that it will only be valid if/when all its children are also valid.

Also, note that we have no way of accessing the FormControls directly like we were doing in Template-Driven Forms; we have to retrieve them using the .get() method of the main FormGroup, which is the form itself.

At first glance, the Model-Driven template doesn’t seem too different from the Template-Driven one; we still have a <form> element, an <input> element hooked to a <span> validator, and a submit button; on top of that, checking the state of the input elements takes a bigger amount of source code since they have no aliases we can use. What’s the real deal, then?

To help us visualize the difference, let’s look at the following diagrams: here’s a schema depicting how Template-Driven Forms work:

By looking at the arrows, we can easily see that, in Template-Driven Forms, everything happens in the template; the HTML form elements are directly bound to the DataModel component represented by a property filled with an asynchronous HTML request to the Web Server, much like we did with our cities and country table.

That DataModel will be updated as soon as the user changes something, that is, unless a validator prevents them from doing that. If we think about it, we can easily understand how there isn’t a single part of the whole workflow that happens to be under our control; Angular handles everything by itself using the information in the data bindings defined within our template.

This is what Template-Driven actually means: the template is calling the shots.  Now, let’s take a look at the Model-Driven Forms (or Reactive Forms) approach:

As we can see, the arrows depicting the Model-Driven Forms workflow tell a whole different story. They show how the data flows between the DataModel component – which we get from the Web Server – and a UI-oriented form model that retains the states and the values of the HTML form (and its children input elements) that are presented to the user. This means that we’ll be able to get in-between the data and the form control objects and perform a number of tasks firsthand: push and pull data, detect and react to user changes, implement our own validation logic, perform unit tests, and so on.

Instead of being superseded by a template that’s not under our control, we can track and influence the workflow programmatically, since the form model that calls the shots is also a TypeScript class; that’s what Model-Driven Forms are about. This also explains why they are also called Reactive Forms – an explicit reference to the Reactive programming style that favors explicit data handling and change management throughout the workflow.

Summary

In this article, we focused on the Angular framework and the two form design models it offers: the Template-Driven approach, mostly inherited from AngularJS, and the Model-Driven or Reactive alternative. We took some valuable time to analyze the pros and cons provided by both, and then we made a detailed comparison of the underlying logic and workflow. At the end of the day, we chose the Reactive way, as it gives the developer more control and enforces a more consistent separation of duties between the Data Model and the Form Model.

RAD

What Is Rapid Application Development (RAD)?

If you’re looking for a faster method of application development, you’ll want to choose something other than the Waterfall methodology, which requires sticking to a planned schedule and doesn’t allow for continuous iterations. That means you’ll end up restarting the development from the beginning every time the client suggests changes.

Rapid application development (RAD), also called rapid-application building (RAB), is better than Waterfall! Though it’s been around for a while, the RAD approach is still popular among those looking for agile methods of application development to keep pace with growing business and client needs.

In the case of you’re searching out a quicker method of application improvement, you’ll want to select something other than the Waterfall method, which requires sticking to a planned agenda and doesn’t allow for non-stop iterations. That means you’ll grow to be restarting the improvement from the beginning each time the customer indicates adjustments.

What Is Rapid Application Improvement, and What Are Its Blessings?

Rapid Application Development (RAD) is a shape of an agile software improvement method that prioritizes speedy prototype discharges and emphasis. In contrast to the Waterfall method, RAD emphasizes using software programs and user comments over strict making plans and necessities recording.

 

Key Blessings and Advantages of RAD

  • Enhanced flexibility and adaptability as dedicated software developers could make adjustments speedy at some point in the improvement method.
  • Quick cycles that reduce improvement time and accelerate delivery.
  • Encouragement of code reuse, which means less manual coding, much less room for errors, and shorter testing times. Increased consumer pleasure due to high-stage collaboration and coordination between stakeholders (web or reactjs developers, customers, and stop users).
  • Better threat control as partners can speak and address code vulnerabilities while maintaining improvement strategies going.
  • Fewer shocks as, not like the Waterfall approach, RAD consists of integrations early on within the software development manner.

 

Steps or Stages in RAD

Stage 1 — Characterize and Finalize Undertaking Necessities

During this progression, experienced web developers sit together to define and finalize undertaking requirements inclusive of challenge desires, expectancies, courses of events, and price go. When you have got defined and perused out each factor of the venture’s necessities, you may are be looking for control approvals.

Stage 2 — Begin Building Prototypes

As quickly as you end scoping the project, you could start web development. Planners and builders will work carefully with clients to make and improve upon working prototypes until the final product is arranged.

Stage 3 — Gather User Feedback

In this progression, models and beta structures are transformed into operating models. Top remote Developers then collect feedback from customers to change and enhance prototypes and make high-quality feasible products.

Stage 4 — Test, Test, Check

This step requires you to test your software program product and make certain that each one its transferring components paintings together as consistent with client expectancies. Proceed to incorporate consumer comments because the code is tested and retested for its smooth functioning.

Step 5 — Present Your System

This is the very last step before the completed product is going to launch. It includes statistics conversion and person training.

 

Are you RAD-ready?

  • Do you need to develop a software product within a short span of time?
  • Do you have an experienced team of developers, coders, and designers who can carry out the work on your timeline?
  • Are you or your client open to adopting RAD and available for collaboration throughout the software development process?
  • Do you have the right tools and technology to implement RAD?

 

Further steps

Adopting a new process requires everyone involved in SDLC, including your team and your client. If you’ve decided the RAD approach is right for you, here’s what you should do next:

  • Make sure your team has an all-hands-on-deck mindset. Talk to your team about the benefits of the new approach and listen to and address their concerns.
  • Ensure that all stakeholders are willing to adhere to the project timelines.
  • Explore application development software and tools. Invest in one that fits your business’s budget and requirements to be able to effectively apply this methodology.
  • Ensure that the development team is fast in communication, passionate and committed for the delivery
