Top Node JS developer skills

The open-sourced, server-sided framework, Node.js has been growing like a fairy-tale. Now If you are tech-savvy and an ardent follower of the latest trends in the app arena, then you must have heard about “Node.js.” The thing about Node.js is that it was developed for applications at scale. All you need is a reliable Node js Software development company, a team having expertise in its wide applications and excellence to its smallest details. The following post acts as an ultimate guide to how to become a Node js expert, roles and responsibilities of a Node.js developer, node js developer skills,  node js coding best practices to consider while dealing with the web framework.

1. All About an Ideal Node.js Developer

According to several sources and stats, Node.js is considered as the world’s most popular technology that is opening up infinite career possibilities for skilled developers. By using the javascript framework and node.js code,   skilled developers can create different web applications, such as apps for social media, instant messaging platforms, apps for real-time monitoring, online gaming, and tools for collaboration . Some of the best examples of node apps include PayPal, LinkedIn, Uber, Go Daddy, Walmart, and more.

Technically speaking, Node.js is an open-source, cross-platform, server-side, JavaScript runtime environment that executes JavaScript code outside a web browser. It offers a non-blocking input-output mechanism that is event-driven. This makes it ideally suited for the development of  fast, highly stable, scalable web applications and also a real-time data-intensive application. I’ve championed the use of Node. js-based tools like browserify, which brings many of the conveniences of Node to browser JavaScript, and Grunt, a task runner that helps automate the web application development process.

Node.js offers good performance and greater consistency ,when compared to other languages and frameworks. This  is why businesses use it extensively to create massive, flexible single-page apps, video streaming apps, and web apps.

Some of the most famous Node.js frameworks

  • Express.js (Express is known as Foundational framework and Express.js was created to expand the basic functionalities of Express)
  • Meteor.js
  • Adonisjs
  • Nestjs

As a Node.js developer or even a team member, write server-side web application logic in JavaScript. Typically, they are responsible for creating back-end modules, linking the app to other web services (often from third parties), and helping front-end developers by integrating their project with the Node.js application.

Their ultimate objective must be to guarantee high efficiency and responsiveness to front-end requests.

Strong JavaScript expertise builds the foundation for being a good Node.js developer You will take lesser time and effort if you have an adequate amount of JavaScript knowledge and will be all set for Node.js. However, if you lack JavaScript knowledge, then you must incorporate that into your schedule right away.

As a Node.js developer, all you require to do is develop, deploy and maintain network applications. For beginners to learn Node, you must somehow be able to manage to exchange data between servers and users, develop back-end components, and connect applications with other web services. These Javascript experts also support front-end  development  by integrating web-based applications.

Web framework based Developers who are aware of the various frameworks are many, so it is very important to become the best out of the rest. Therefore to ensure success you must possess extensive knowledge of Node.Js based services,  experience of  working on numerous projects and should also be aware of bug fixing.. An accomplished Node.js developer will be someone whose expertise results in the stable, fast, and secure exchange of data between servers and end-users.

1.1 List Of Must have Skills  to Become a Node.js Developer

I feel that hiring developers could be easier than becoming one. Apart from having basic knowledge and attributes, a Javascript developer must possess different supporting skills, along with that he must also have knowledge about other tools and regularly check on the updates . Regardless, everyone still wants a Node.js or an open-source developer, and for good reason.

Now not all developers are equal. I mean some might be good in regards to experience while others might be more knowledgeable, but irrespective of your position, Here is the list of must-have skills (Node.js developer skills) that might help you stand out from the crowd.

1.2 Better Get Going with the Basics-

1 Node.js Architecture – Depending on the architecture of the single-threaded event loop model which implies that a single thread in Node.js will conduct client requests. Node.js has an event-driven design enabling developers to manage several client requests simultaneously.

2. Installation of Node.js – Node.js is pretty simple to install. A stable version of Node.js can be downloaded from the Node.js official website. You have the option to install Node.js based on your OS and system configs, and then you are allowed to begin working on it instantly. To use Node.js, ensure that your team uses RAM which is at least 4 GB.

3. Node Package Manager – Node.js comprises such pre-built libraries featuring their own code to create various functions. With the NPM command, you can easily install the appropriate library and implement it in your app. These libraries, therefore, help a lot to accelerate the process of application development.

4. JSON Files – Another basic and perhaps most useful component to know in Node.js is the JSON file. As a Node.js developer, you have to create JSON files. In simpler terms, including the script used in the project, it maintains and keeps the data about packages and dependencies. You may easily open this file and review the details if you ever have to review which packages or dependencies are made to use in the application.

1.3 Database Management-

Database management is an important skill set, especially when working with businesses or applications that take in a lot of data. Node.js developers should be able to handle several databases and even integrate multiple data sources them  if necessary. Perhaps most importantly, they need to be able to maintain database security the entire time. One more important thing here is about creating database schemas  that support business processes, workflow and serve your clients according to their project requirements.

1.4 Managing Time –

Other than technical skills, Time management is pretty vital. More and more developers require this skill because they are compelled to work on many projects or many parts of the puzzle for one project, all at once.

In fact, an ideal expert is considered the one who knows how to prioritize their tasks, provide accurate time estimations until completion, and get things done by their deadlines.

1.5  Creating Compliant Code –

Another interesting skill to possess is to create or write efficient codes that are readable and compliant. So that everything works well in sync and doesn’t possess any threats later on. Non-bloated code written will also help applications run their best.

Readable code is important so that other developers can edit the code if necessary.

1.6 API Communications –

You see, no development environment is 100% perfect. You are required to make it perfect. And since every business has different needs so must be every web application here. These needs also change over time.

This is why developers with an understanding of API communications are in high demand. They can use APIs to integrate tools and projects into Node that will make development more efficient, saving time and effort.

1.7 Error-Handling Skills –

Error-handling is a crucial part of developing software and applications that work right. Make sure that the web developer you’re hiring knows exactly when to crash, when to log an error, when to continue, and when to retry. Error handling is one of the essential  skills required for Node developers.

Troubleshooting and syntax manipulation are basic error handling skills that every Node.js dedicated developer  or other developers need to demonstrate.

1.8 Use of Asynchronous Programming-

As a Javascript or an open-source developer, you are supposed to have a good grasp on asynchronous programming. After all, non-blocking is what Node.js is all about. With asynchronous I/O, the waiting time for requests can be significantly reduced. Two or more functions can be executed at the same time so that developers can be more efficient and productive.

But, because asynchronous programming is a fairly new method, there are still quirks that need to be considered by every developer. Without a proper understanding of its workarounds, developers won’t be able to perform appropriate actions.

As a result, developers will take more time with their projects. That’s counterproductive, and you don’t want that.

1.9 Knowledge of Front-End Technologies-

Front-end development doesn’t only mean the outcome or what you see as a user. But it’s way more than meets the eye. So, it is crucial to have extreme knowledge in frontend development and a basic understanding of HTML and CSS for Node.js software developers.

2. Roles and Responsibilities of a Node.js Expert

Apart from crucial knowledge and must have skills, a Node.js developer must be able to possess certain roles that he has to carry out in their daily job routine. The below-mentioned tasks need a Node JS Developer’s utmost precision and dedication.

  • Working on data streaming applications and platforms
  • Working with server-side proxy and applications
  • Contributing to improvements in the fields of infrastructure and process
  • Working on PayPal Node JS Payment process management
  • Back-end services of customer-friendly graphical user interfaces
  • Wireless connectivity, big data analytics, and many more

2.1 Developers are Responsible for Several Tasks –

  • Developing and maintaining all server-side network components.
  • Ensuring optimal performance of the central database and responsiveness to front-end requests.
  • Collaborating with front-end developers on the integration of elements.
  • Designing customer-facing UI and back-end services for various business processes
