Node JS vs Deno: Find Your Perfect Solution for Mobile Banking App

Deno is an emerging orb on the JavaScript realm and individuals assume that it will stamp out Node.js. However, when it comes to the finance industry, you need money management software that revolves around improved services and robust security.

In this case, it becomes imperative a technology that is not only advanced but also reliable. When you look at the picture this way, Node.js happens to be an ideal option.

This has increased the dilemma and entrepreneurs are always confused about whether to opt for Node.js or Deno. Alongside the confusion, there is strong competition among both these technologies.

The main purpose of this extract is to provide you comprehensive information about both these technologies and how they can help with your financial data.

We have discussed the following:

  • Understanding Node.js
  • Understanding Deno
  • Key Factors That Distinguishes Node.js and Deno
  • What Should You Choose?

Understanding Node.js

Node.js was created in 2009, by Ryan Dahl. It is a server-side JavaScript background that relies on a JavaScript engine which is Google’s V8. This unique tech concentrates on event-based HTTP servers.

This technology has concentrated on server-side JavaScript and brought it to vision. The presence and optimal use of this JavaScript led to the birth of web applications with the help of a distinct programming language.

Node has been widely used to serve frontends, build APIs, and build microservices architecture, among others. Node.js development services can guide you to make optimal use of the technology.

In 2018, Mr. Ryan Dahl shared his thoughts on design mistakes in Node, popularly referred to as ‘10 Things I Regret About Node.js’. He further shared that he regrets some preferences that he concentrated on during the creation of Node.

He also mentioned that during the inception of Node, JavaScript was a different language and perceived diversely.

Moreover, he observed the absence of advanced features such as:

  • ES Modules
  • Promises and Await/Async
  • TypeScript

He also voiced his thoughts on significant design flaws that cannot be rectified without revising the fundamentals of Node. He thought it is wiser to end the support for traditional applications and instead, introduce Deno.

The introduction of new and advanced features can assist financial institutions to provide rapid and improved services to their customers. These facilities can help win and retain customers at a better rate.

Understanding Deno

Deno is not a bifurcation of Node, instead, a new implementation that runs on contemporary features of the JavaScript language. However, you cannot ignore that the name is a puzzle of Node.

Deno is built in Rust while Node’s implementation is in C++. Deno is a secure runtime for TypeScript and JavaScript built on Google V8. Deno uses Tokio to create an event loop and is transcribed in Rust.

Key Factors That Distinguishes Node.js and Deno

Deno ships are independent, single, and executable with a few built-in tools that can ease the developer’s experience:

  • Debugger
  • Bundler
  • Documentation generator
  • Dependency inspector
  • Test runner
  • Formatter
  • Linter

These are standardized Deno tools and hence they provide assured and comprehensive support. As a single executable, Deno has self-update capabilities and this is possible due to the Deno upgrade.

This way, it can fetch either the updated or specified version and replace the existing one.

Version managers allow you to install multiple versions. In the case of Node, Version managers can install/update new versions.

Discussed here are key distinguishing factors between Node.js and Deno:

Security

The primary feature of Deno is to offer security. Deno by default is a secure solution with a secure sandbox to execute code effectively. It imitates the permission model that the browser uses.

Unless permissions are provided it cannot access the network, file system, and environmental variables. You have to provide access permissions to the Deno process on the command line to use the specified location.

Alongside, Deno ensures that no information gets deleted without confirmation.

On the contrary, Node.js offers quick and uninterruptible access to all these destinations. Node.js has certain specific security measures that restrict intrusion from unwanted sources.

The security feature plays a pivotal role in the digital journey of a financial institution and hence this factor needs utmost attention while choosing the technology for your financial mobile app.

Elite TypeScript

Deno functions on TypeScript, hence it supports out-of-the-box without the need for any additional configuration tools or installations. On the other hand, Node.js comes with a default configuration file. You can add configuration files as per your choice as well.

TypeScript is a subset of JavaScript and hence Deno can easily function in presence of both the Scripts.

The Deno team predicts that TypeScript can rise higher than JavaScript once it takes V8 to parse TypeScript. However, this just an assumption and nothing substantial has been announced or implemented.

Remember, JavaScript has a wider and profound history, and Node.js relies largely on it. Although there are a few shortcomings in Node.js it is still reliable and an appropriate choice for the financial industry.

Standard Modules

Deno’s Core team audits and offers standard modules of utilities and helpers. These modules are updated alongside the latest Deno releases.

Since the inception of Node.js, Common JS is the standard JavaScript module supported by npm. But, since the ECMAScript committee announced a different standard officially and ES Modules, which is supported by jspm.

It is important to use modules that can save customer data and keep it intact. This way, your financial institution can use customer data wisely to design marketing strategies.

An advanced standard module can help streamline data, analyze it, and highlight the real picture. Experts can recommend you the right module that caters specifically to your services and implement it successfully in your mobile app.

Package Management

Node.js offers npm to handle all your packages. On the other hand, Deno allows you to install packages with a single click on the URL. You can also import packages as a library in the script from the URL.

Deno allows you to obtain modules from anywhere and there is no need for a customized centralized repository.

This is one of the distinguishing factors between Node.js and Deno.

Inefficiency to adopt a modern package can restrict your customer services. Therefore, evaluate this factor properly to make the right decision.

What Should You Choose?

The truth is that Node.js and Deno are not a competition, instead, they are alternatives. You have to examine the purpose and requirements of your financial app as it helps choose the right option.

In case, you fear that Node.js is likely to be replaced shortly then it is not the situation. Node.js has a large ecosystem of developers to depend on.

Besides, there is no certainty as of now that Deno can surpass all tough circumstances. It has advanced functionalities but cannot be considered the best over Node.js.

The choice largely depends on your app requirements and the financial services you want to include in your mobile app. Finance digital transformation has opened several avenues and hence Node.js has a long way to go.

Node.js is here to stay and time will tell.
