  • Providing support for the developers working on front-end applications.
  • Contributing to improvements in the fields of infrastructure and process.
  • Hiring node.js developers entail back-end services of customer-friendly graphical user interfaces.
  • Maintaining a good customer experience is their all-time duty.

Responsibilities Of Node.js Developer

To make this guide helpful for both technical and non-technical employers, we have listed all the possible responsibilities of top Node.js developers.

You can even mention these parameters in your advertisement as the job description to hire node.js programmers.

Out of many developer responsibilities, writing codes in script languages like JavaScript, IcedScript, and CoffeeScript are the basics. Also, the responsibilities that a node.js developer must possess are:

Benefitting from Agile Methodology

Agile Methodology is based on the concept of agility i.e., the ability to adapt to changes. With the help of continuous changes or updates, the performance of software improves. Hence, this methodology is widely used as part of node.js development services to develop website servers or applications on Node.js.

Some common principles of the agile methodology are:

  • Keep developing and modifying the software at times.
  • Analyze the current competition and make the software compelling to the latest trend.
  • Try to finish the work in the shortest possible time.
  • Developers must collaborate with business professionals to yield the maximum output.
  • Taking regular feedback from customers to eradicate loopholes in the software.

The requirements of the user are susceptive to changes. The developers must create systems with an agile method that can adapt to carry out its functions. It simply contains a list of measures of ways of developing software that enhances its productivity. Hire dedicated node.js developer who is well versed in using this methodology and can bring creativity and a high-performance rate to the developed web applications.

Having Front-end Knowledge

As mentioned earlier, node.js is used in both front-end and back-end development. Many developers working in this field are limited to back-end development only.

Hire node.js programmers India to connect these applications to databases with JS and the operations that won’t be visible on the user interface.

And, one cannot imagine a web server or application without a front-end. The front-end of the applications is used by customers. Hence, they need to be developed in a user-friendly way. In the case of Node.js, different frameworks act as the base of front-end development.

It is even used to create NPM scripts, gulp tasks, web pack configuration, etc. This makes it important to set the criterion of full-stack development at the first stage itself. Because if you hire node js programmers differently then it may make the whole process even more expensive.

Writing Clean Codes

Writing a clear code is more than writing just a well-running program. Here, a clean code means a certain way of programming, including object-oriented programming, easily understandable code, error-free code, etc. Wasting time on correcting errors full or unclear codes is considered an inefficient practice.

This is why to hire node.js programmers who write clear code is the best choice. Following this is the responsibility of every software developer, including Node.js ones. Because this trait defines a coder as a professional.

As one developer writes clean code, it becomes easier for other programmers to understand that. Doing so can help to regulate and divide other roles and responsibilities. Also, they serve as great team leaders and hence improve the overall performance of the business products.

This kind of professional can come out as a great team leader and will improve the quality of your business software. To search for the right candidate, you can ask them about the Node.js unit testing tools to test their awareness about the same.

This should be done since specialist developers are fond of using these tools to improve the quality of their software.

Adding Third-party Services to the System

Any complex sites & apps or software built for business-related purposes always requires some third-party service integrations to run smoothly. Especially for payment purposes. And you need to make sure that as you hire remote node js developer gets it done efficiently.

For example, in the case of a food outlet website or application, you will need one or more kinds of payment-related services, such as Paytm, Amazon Pay, Google Pay, etc.

Hence, it becomes a responsibility while hiring node.js developers for integration, to reduce cost & time. As Node.js is a scalable platform and is used widely because of this specialty only. It allows for easy integration of third-party service integration with prepared modules. Making the developers write fewer codes for more functions.

This improves the quality of web servers and applications. And this can only be achieved with the help of professional developers.

Working with Database

Do you ever think of how websites and businesses reach the top of the market from scratch? All you need to do is deep and smart research about your customers and past content to help you go in the right direction. And to your surprise, Nodejs developers for hire play an important role in this too. Also, as developers develop the back-end applications, they have to work with databases and records maintaining software.

For this, you need an efficient space in the cloud to store that data. Since Node.js has many libraries and inbuilt drivers, it helps you store data. All such libraries stored in npm even speed up the configuration process. This makes the data configuration and analysis process easier.

One such framework is MongoDB. It is used for the maintenance of the database and adding or receiving data. Thus, to make the right use of data, you need to hire a node.js developer who is familiar & good with the tactics of Node.js database management.

Keeping Up with the Latest Node.js Trends

Here we go.

Technical Interview Questions to Ask While Hiring Node Developers

What do you understand by closures?

A Closure is a bundle of functions that has access to other variables that are present in the outer scope. It can be used to convert global variables into private variables.

Can you explain Modules in Node.js?

Modules in JavaScript are the functions that can be reused. Also, they have their conditions and surroundings that cannot be interfered with by other modules. It helps the offshore node js developers to rapidly & securely build the architecture.

What is a Cluster?

It is a process that is used to handle the load during thread execution when working with multi-core systems.

Why is Node single-threaded?

It has been observed that single-thread operations run better than multi-thread operations. Using single-threaded architectural pattern operations can help to improve the performance of Node.js. And your hire remote node js developer must be well-versed in it.

What is Node Package Manager?

NPM or Node Package Manager is used to install and manage Node.js repositories and packages.

What is Node.js? How it is used?

Node.js is an open-source framework built on Chrome’s V8 JavaScript engine. It runs JavaScript instantly into native machine code. Enabling the web applications to run outside the client’s browser.

This lightweight framework is highly useful in building server-side applications. And also expands JavaScript API to develop standard server-side functionalities.

Apart from these, Node.js is highly useful to create data-intensive applications such as real-time apps, Network apps, etc.

What is the difference between Asynchronous & Non-Blocking?

This is the basic question to ask & get answers to as you hire dedicated node js developer.

Asynchronous in Node.js enables developers to carry out asynchronous HTTP requests without waiting for the server to respond. So the app simultaneously works on the remaining blocks and replies as soon as the server response is made.

Non-blocking functions are mostly utilized along with the I/O Operations. And these functions instantly respond with any data that is available and operate based on the requests. By chance, if any answer couldn’t be obtained, then the API responds promptly with an error.

What do you mean by the Callback function in Node.js?

Node.js is an asynchronous JavaScript framework, which depends hugely on the callbacks.

Callbacks are usually called after the completion of the assigned task. It enables the other code to execute parallelly and stop any blocking. Due to this, a Node.js application has the power to manage a wide range of I/O operations simultaneously.

What is package.json?

Package.json is a Node.js file kept at the core of the Node.js system. It is a file that holds the metadata for a specific project. Hence, the package.json file is present in the root directory of the Node application or module.

Here is how the package.json file appears instantly as soon as you create a Node.js project with the help of the command:npm init.

You can later edit the parameters as soon as you form a Node.js project.

{

“name”: “node-npm”

“version”: “1.0.0”

“description”: “A demo application”,

“main”: “index.js”,

“scripts”: {

“test”: “echo “Error:no test specified” && exit 1”

}

“author”: “Taha”,

“license”: “ISC”

}

What is Callback Hell?

Callback Hell is popularly known as the pyramid of doom. It occurs because of the actively nested, unreadable, and uncontrollable callbacks that result in difficult-to-read and debug code in the Node.js applications.

The main reason why this takes place is that developers haven’t executed asynchronous logic effectively. Also, offshore node js developers can state that this can be taken care of by using a modular process. Here, this process breaks down callbacks into separate functions that do not rely on each other.

What are Promises?

Promises are nothing but an alternate way to write asynchronous code. Plus, they assist in managing asynchronous functions in Node.js applications.

Despite promises initially launched in the 80s, they got attention only after the evolution of JavaScript. And now, they are utilized in the latest programming languages.

In short, promises can be utilized to get an error or a result. Also, same as the classic If-else function, developers are needed to utilize the <.then> function to implement promises in a Node.js application.

What is Control Flow Function?

Anytime you write asynchronous code in Node.js, you must integrate many callback functions. If you are building a highly complex application, there is a strong possibility that you might cross the max limit of the callback function, which is 63.

After this, you will face callback hell. Hire nodejs developer who knows that one of the most effective ways to deal with this situation is to utilize the control flow function. It assists in arranging the asynchronous code by which your app doesn’t go through the callback hell.

Here are some of the things in which the control flow function can assist you:

  • Fetch data
  • Manage the execution order
  • Integration limit
  • Call the next step in the program

Lastly, you will have enhanced control over the code in your Node.js application.

Why should we use Node.js?

It is a subjective question in which the offshore node js developers can present their views about the tool and its advantages. As there are many essential advantages, a candidate can mention all the necessary things or the ones that reap the maximum benefit.

Several things that one can list about Node.js is: it is a quick, asynchronous, unified programming language and data type, etc.

In general, Node.js is a highly popular tool in the industry for developers for doing server-side development based on JavaScript.

What are Stubs?

Stubs are certain functions or programs mainly utilized for stimulating the specific module or component behavior. Also, if you hire node developers, they frequently use these in test cases because they offer answers that resolve the issues that might originate in the modules.

In short, stubs are mainly objects that keep preset data and utilize answer calls at the time of tests.

What is an Event?

The event is a primary feature of Node.js. They represent several actions that are being carried out on a web page. Moreover, they are managed by an event handler that writes the necessary code that runs the events.

What is Event-driven Programming?

Event-driven programming is a type of programming that utilizes events for activating various functions. Here events include small to big actions like a mouse click, keypress, etc.

As soon as an event gets activated, a callback function is executed that is registered with the element. This method works according to the publish-subscribe pattern. As for event-driven programming, Node.js uses it efficiently in contrast to other technologies.

What is Single-threading?

Single-threading enables developers to carry out asynchronous programming. Here, if the developer works on the standard web loads, a single thread provides higher performance and scalability as compared to typical thread-based execution.

What are worker processes?

Worker processes are mainly the processes that are executed behind when you are busy working on some other tasks. Also, they perform various activities like sending emails, fixing variables, etc. So, they are highly beneficial for developers as they finish many tedious tasks.

What is Express.js?

Even though this question is not directly linked with Node.js, it is an important question you should ask when you want to hire Node.js developer. Because a developer should know what Express.js is. As it is explicitly built for Node.js.

The demultiplexer is mainly a notification interface present in the JS host. It is utilized to fetch details about particular events and form quests, consequently offering the supposed Event Que.

What is REPL?

The full form of REPL is Read Evaluate Print Loop. It mainly displays a computer environment. And looks like a Windows console or Unix/Linux shell where the command is entered. This shell is widely beneficial to run specific JavaScript statements.

Does Node.js have sub-branches?

Several questions might surprise Node.js developers for hire and this question is one of them.

In case the response is NO initially, then the candidate is incorrect. Even though Node.js is a single-threaded service, it also consists of child threads. But it doesn’t showcase them to the developer.

These questions help you to identify whether the candidate has a better understanding of Node.js.

How does Node.js work?

This is something your candidate must know if you are planning to hire node js programmers for your project. First of all, the client transmits a request to the webserver to communicate with the web application. Requests are mainly blocking or non-blocking operations that include querying, updating, or deleting.

Node.js collects all the requests made by the clients & transmits them to the event loop. The event loop is mainly a functionality that looks after all the external requests & turns them into a callback function.

At the time of executing a request, Node.js links up a callback function and transfers it to the back-end. As soon as the response is available, an event is involved that activates the linked callback function to share the response.

And this is how Node.js functions.

What are the applications of Node.js?

Hire nodejs developer to build several applications on Node.js like

  • I/O bound Applications
  • Data Streaming Applications
  • Data-intensive Real-time Applications (DIRT)
  • JSON APIs-based Applications
  • Complex SPAs (Single Page Applications)
  • Internet of Things
  • Microservices architecture

One of the most important things here is that Node.js is not proper for building complex apps that require more CPU usage.

What is NPM?

NPM is referred to as Node Package Manager. It mainly looks after various packages and modules present in Node.js.

Also, it comes with two of the most essential functionalities:

  • It has an online repository for node.js packages/modules that are available inside it.
  • NPM offers a command-line utility tool to install Node.js packages. And look after the version management and dependency management of Node.js packages.

Apart from NPM, there are various other packages of Node.js, which are also extensively used by the developers.

What are Modules in Node.js?

Modules in Node.js are similar to JavaScript libraries and are highly beneficial in applications to integrate a specific group of functions.

Node.js has various built-in modules which can be useful to add various primary functionalities to a web application. Here is the list of some of them:

Primary Modules Description
HTTP Consists of classes, methods, and events to build a Node.js HTTP server
