How to Hire Node JS developers: A guide to efficient tech hiring

Introduction

Critical factors are at play when you want to hire a Node JS developer. The latter is in charge of building server-side web application functionality in JavaScript and JavaScript variations like CoffeeScript, IcedCoffeeScript, and other programming languages. Node.js developers often develop back-end components and connect the application to other (often third-party) web services. Furthermore, they assist front-end developers by integrating their work with the Node.js application.

Considering the technical expertise and experience required for this role, organizations need to utilize methods and tools that ensure objective assessment of candidates’ indispensable competencies. This guide outlines the necessary steps and methods that will help you hire Node JS programmers who meet your organizational requirements.

 

A brief history of Node.js

 

According to various reports, Node.js is utilized by 1.4 percent to 2.2 percent of websites throughout the world.

According to a Stack Overflow Developer Survey, Node.js is the most used framework in technology today, and its popularity is only increasing. The flexibility and convenience of JavaScript, combined with the strength of a fast async loop and a vibrant community, has boosted Node.js developers’ productivity and power.

JavaScript is a computer language developed by Netscape as a scripting tool for manipulating web pages within the Netscape Navigator browser. Netscape’s business strategy involved selling web servers, which featured a program called Netscape LiveWire that allowed users to construct dynamic sites using server-side JavaScript.

Unfortunately, Netscape LiveWire was a flop, and server-side JavaScript didn’t gain traction until lately, thanks to Node.js. The timing was a significant influence on the growth of Node.js. Only a few years prior, “Online 2.0” apps (such as Flickr, Gmail, and others) had established JavaScript as a more serious language, demonstrating to the world what a contemporary web experience might be like.

As multiple browsers raced to provide consumers with the most outstanding performance, JavaScript engines improved significantly. Major browser development teams worked hard to enhance JavaScript support and identify ways to make JavaScript run quicker.

 


Framework and tools for Node.js

Node.js is a low-level programming language. Thousands of libraries were written on Node.js by the community to make things easier for developers. Many of these have become popular alternatives over time. The following are a few examples of those worth learning.

AdonisJS:

A TypeScript-based, full-featured framework that prioritizes developer comfort, stability, and confidence. Adonis is a Node.js web framework that is one of the quickest.

Egas:

A Node.js and Koa framework for building better corporate frameworks and apps. It's one of the simplest yet most powerful ways to set up a web server. Its success is due to its minimalist approach, which is unprejudiced and focuses on the essential qualities of a server.

Fastify:

A web framework that gives developers the best possible experience with the least amount of overhead and a flexible plugin architecture.

Step 1: Skill identification

 

A checklist of mandatory Node.js developer competencies

 

Before you advertise that you want to hire Node developers, the following checklist will ensure clarity about the vital Node JS developer skills and experience.

  • Complete understanding of Node.js and related technologies.
    The candidate should have a grasp on how core Node.js works and be intimately familiar with the Node.js API.
  • Knowledge of frameworks for web applications.
    The web application framework is one of the fundamental necessities for every Node.js online application. Hence, before you hire NodeJS developer, you should assess their knowledge of web application frameworks.
  • Awareness of safety and security modules.
    Security on the internet has always been important, but with the recent breaches and difficulties, it is now a must. The developers you hire should be aware of severe security threats on the internet. It would help in identifying and auditing any security flaws in your applications.
  • Database expertise.
    Your Node.js code will be inadequate to employ your web application unless your developer understands how to operate a persistence layer, like a database, to store dynamic data. There are far too many database choices to discuss here, but an Object-Relational Mapping (ORM) tool is often the most straightforward strategy.
  • Cloud platform know-how.
    It is vital for a NodeJS developer to understand the nuances of cloud platforms, related upgrades, alternatives, etc., to ensure efficacy in the functioning of codes, storage and other aspects of web applications.

 

Step 2: Job description

 

An outline of responsibilities and expectations

 

Following are the day-to-day responsibilities and NodeJS programmer job description that will help you communicate your requirement to applicants.

  • Working with front-end developers to combine user-facing components with server-side logic.
  • Writing code that is reusable, testable and efficient.
  • Designing and implementing low-latency, high-availability and performant applications.
  • Ensuring the proper implementation and functioning of software security and data protection.
  • Integrating data storage solutions with databases, key-value stores, blob stores, and other related tasks.

 

Step 3: Talent sourcing

 

The best platforms to hire dedicated NodeJS developers

 

You may have a hard time recruiting experienced Node.js engineers, no matter how thorough your hiring procedure is. This is especially true if you do not have a lot of experience with the development process. As a result, if you’re trying to hire dedicated NodeJS developers, you should check all your possibilities.

It is crucial to explore multiple channels like social media, job portals and dedicated platforms to find tech talent.
