Hire top NodeJS Programmer with Ultragenius

NodeJS is a Javascript backend runtime environment built on the Chrome V8 engine and executes Javascript code independent of the web browser. Node.js is mainly used for non-blocking Input/Output programming. Its single-threaded nature makes it very fast for developing web applications. It is used for backend services and generating dynamic content on the webpage. NodeJS can gather form data and perform CRUD ( Create, Read, Update, and Delete ) operations and easily modifies data in your database.

Want to hire Node.js developers on your own? Here are the skills you must look for while hiring a Node.js developer

Hiring Node.js developers can be a complex task for you if you are a non-technical manager. Javascript is the core skill of any developer without which no framework and related skills can be mastered and hiring the top skilled  Node.js developer among the thousands of developers will be challenging to you even if you belong to technical background. But, no worries, Ultragenius is here to assist you in hiring only the top 1% Node.js developers.

These skills you must ensure in any Node.js developer – 

 

Strong knowledge of core Node.js modules -

Node.js modules are the folder containing multiple files, that are imported using require() method. The developer must possess strong knowledge of – 

  • HTTP

HTTP is a built-in package for designing client-server architecture and is designed to support various protocol features. ExpressJS framework uses HTTP to make the server request. 

  • File System

This Node.js module of the file system help developer to work with the file system of your computer and is used to read the files, write the files, rename the files, update the files, and delete the files. 

E.g. var fs = require(‘fs’);
fs.readFile(“file.txt”, “utf8”, function(err, content) {
if (err) {
     return console.log(err);
    }
 console.log(content);
});

  • Buffer

Buffer provides a way of handling data. It is a global object in Node.js and uses many methods like alloc(), allocUnsafe(), allocUnsafeSlow(), byteLength(), compare(), concat(), copy(), entries(), fill(), equals(), includes(), indexOf(), from(), isBuffer(), and many more.

  • Globals

Node.js has objects that are available in all the modules in NodeJS and can be directly used while developing a web application without importing them.

 

  • URL

The URL module resolves a web address that is readable. To include the URL module, add var URL = require( ‘ url ‘);

Strong knowledge of HTML5 and CSS3

HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are the two core technologies to design a web page,  the most used versions are HTML5 and CSS3. You must hire such a developer who has practiced and worked deeply with these technologies. Knowledge of Flexbox and CSS Grid, in addition to Bootstrap, Semantic and Structural Styling, and Foundation is a must to a Javascript developer. Along with this, the developer should be well-versed in Javascript libraries especially jQuery and CSS grid systems. 

Proficient in using NPM and third party integration

A CSS pre-processor is a program that extends the functionality of CSS and compiles it

Next to NodeJS, the developer must know about Node Package Manager (NPM), how to use this tool for working with web applications on the backend side. NPM is the package manager for handling several server-side dependencies. NPM facilitates the developer by installing the Javascript libraries an application needs for development, testing, and production.

The developer must know the following commands –

  • npm install
  • npm init
  • npm start
  • npm ls
  • npm version
  • npm uninstall
  • npm update
  • npm update -g
  • npm doctor
  • npm deprecate
  • npm outdated
  • npm search
  • npm help
  • npm owner

Experience working with Node.js frameworks

For developing a web application in Node.js, its frameworks offer unique design patterns. Examples are Express.js, Meteor.js, Total.js, and Nest.js, being on the top is Express.js.

Express.js matches its pace with the high-speed input/output operations and aligns with the single-threaded node.js environment because it uses the concept of asynchronous programming where multiple operations are executed independently of each other. Express provides a robust application user interface (API) for client-to-server requests and interactive user applications. 

Meteor.js is another popular cross-platform framework of Node.js known for rapid prototyping with Command Line Interface (CLI) and making smooth data flow between the client-side and the server-side in any application where high-performance real-time functionalities are required. Developers can even deploy live updates on the already installed applications without interfering with the current ongoing session. 

Socket.io is also known for its real-time updating of responses and requests. It acts as bi-directional communication support for clients and servers. An example of this is Zoom, which needs communication of real-time bidirectional data to various participants and Socket.io makes it possible only with fewer lines of code.

Worked with Version Control System in the Past (VCS)

For developers, version control technologies such as Git, SVN, TFS, and Mercurial are important. Git is the primary tool of choice for most software engineers. In order to collaborate and organise your work, you need a version control system that can handle frequent changes. In addition to comparing old and new code, Git may be used to extract code from a repository, keep track of commits, and more.

Besides this, the developer must be familiar with branching and merging in order to allow other developers to work on the code at the same time.

Hands-on experience of Testing Frameworks and Tools

Because of the increasing importance of testing throughout the development process, it is essential for Javascript developers to have this skill set. Developers should be experienced with Jest, Chai, AVA, and Tape for unit testing. All testers must be familiar with Selenium, Cucumber.js, Webdriver, Nightwatch.js, Puppeteer and Cypress. Karma knowledge is required for integration testing.

Strong grasp of Asynchronous Programming in Node.js

Asynchronous programming allows any program to serve multiple requests without blocking the execution of its previous request. All of the I/O functions in NodeJS  I/O are non-blocking and accept callback functions. If the developer wants to download any file, then the Node.js server will put this downloading job in the background without stopping the current flow of any process.

E.g .

var fs = require(‘fs’);
var fcontent ;
function readingfile(callback){
fs.readFile(“readme.txt”, “utf8”, function(err, content) {
fcontent=content;
 if (err){
 return console.error(err.stack);

}

callback(content);

 })

};

function mycontent() {

  console.log(fcontent);

}

readingfile(mycontent);

console.log(‘Reading files….’);

Firm understanding of the databases like MongoDB, MySQL, and PostgreSQL

For developing real-world web applications, the developer should be experienced with at least one of the databases, MongoDB, MySQL, and PostgreSQL. These databases can store the content in any type of format and are frequently used with NodeJS. 

To work with MongoDB, the required library is mongoose and for working with MySQL, the required library is mysql. The necessary operations to perform with these modules are – 

  • Connection Pooling – Specify the number of database connections that should be maintained and saved by Node.js.
  • Create the connection to a database. Create a callback function that can be invoked whenever the “create” method is executed.
  • To retrieve and manipulate data, execute queries from the database with the help of commands such as SELECT, UPDATE, INSERT, and DELETE.
  • Close the connection and create a callback function that can be invoked whenever the “close” method is executed.

Ability to write Cross-Browser compatible code

You must hire developers who can write the code that is compatible to run on any browser platform like Mozilla, Chrome, Internet Explorer. NodeJS supports cross-browser compatibility to its web applications and uses NightwatchJS for testing cross-browser applications.

Proficient Knowledge working with REST (Representational State Transfer) API (s) ​

REST API is an Application Programming Interface that uses HTTP requests to GET, PUT, POST, DELETE the data over www. The developers you are hiring should be well versed with the principles of REST – 
  • Stateless – 
The client sends the requests to the server containing all the necessary data to be dealt with. The data can be a query-string parameter, a part of URI, context body, and headers also. The URI uniquely identifies the resource and the body contains the information about the requesting resource’s state.
  • Client and Server – 
REST provides a uniform interface that separates the client from the server and helps in improving the UI portability across various platforms they use. It also increases the scalability of the server components.
  • Uniform Interface
REST API ensures uniformity throughout the application by defining four interface constraints –  Resource Identification, Resource Manipulation, Self-descriptive messages, Hypermedia.
  • Layered System 
REST provides a layered system architecture that limits the component behavior thereby ensuring stability. Layered system enables load balancing and enhances scalability by providing shared caches. It also helps in increasing the application’s security because components in each layer cannot communicate with the next immediate layer.
  • Cacheable
REST allows the client to download the applets and extend them via the interface to use in their applications.

Error handling skills

While hiring, ensure the developer’s knowledge on when to crash when to log an error, when to retry, and when to continue with the application. Examples you can ask about Troubleshooting and Syntax Manipulation are the main error-handling skills that every NodeJS developer should know.
