Hire Node Js Developer
Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere" paradigm, unifying web-application development around a single programming language, rather than different languages for server-side and client-side scripts.
REQUIREMENTS
Below are the qualifications expected of a React.js developer :
- Bachelor's degree in computer science, information science, or similar.
- At least two years' experience as a Node.js developer.
- Extensive knowledge of JavaScript, web stacks, libraries, and frameworks.
- Knowledge of front-end technologies such as HTML5 and CSS3.
- Superb interpersonal, communication, and collaboration skills.
- Exceptional analytical and problem-solving aptitude.
- Great organizational and time management skills.
- Availability to resolve urgent web application issues outside of business hours.
JOB DESCRIPTION
-
We are looking for a highly capable Node.js developer to optimize our web-based application performance.
-
You will be collaborating with our front-end application developers, designing back-end components, and integrating data storage and protection solutions.
-
To ensure success as a Node.js developer, you should possess extensive knowledge of Node.Js based services and experience in a similar role.
-
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.
NODE JS FEATURES
Single Threaded
Node.js operates on a single thread. It is based on the “Single Threaded Event Loop Model” architecture which can handle multiple client requests. The main event loop is executed by a single thread, but in the background, the input-output work is performed on separate threads; as Node API’s input-output operation is asynchronous (non-blocking design) in order to accommodate the Event Loop. Event Loop is what allows the node.js to perform all the non-blocking operations.
Asynchronous
Node.js is asynchronous by default, i.e it operates in a non-blocking way. Meaning, when a client requests a server, a single thread handles the request; it checks if the request involves any database interaction if it does not; the request is processed and the server sends back the response to the client. The thread is ready to handle the next request.
Event-Driven
The event-driven concept is similar to the concept of a callback function in asynchronous programming. The only difference is that the callback function executes once the asynchronous function returns its result and events are triggered on its associated event handler. Node provides a module called “Event” which consists of an “EventEmitter” class that gives us the privilege to implement event-driven programming. An Event handler is a function that is called when an event is triggered. The main loop listens to the event triggers and then calls the corresponding event handler.
Open Source
Node.js is open-source, which in simple terms means that it is free to use. We can install Node.js from https://nodejs.org/en/ according to our platform.
Performance
Node.js is built on Google Chrome’s V8 JavaScript engine, which helps us in faster code execution. The engine compiles the JavaScript code into machine code which makes our code easier and faster to implement in an effective manner. Concepts like asynchronous programming and the way it operates on non-blocking input-output operations make its performance high. Node.js uses events highly which makes it pretty fast.
Highly Scalable
Node.js applications are highly scalable as they operate in an asynchronous (non-blocking) way. Node.js works on a Single thread, where the time when a single request arrives, it starts processing it and is ready to handle the next request. Also, once the response is prepared, it is sent back to the client.
Node Package Manager(NPM)
As we are familiar with, the Node Package Manager is a package manager for the Node JavaScript runtime environment and is a recommended feature of the Node.js installer. It is the world’s largest online repository. It also looks after the management of the local dependencies of our project. It has nearby 50,000 – 80,000 packages in its public online repository.
No Buffering
Due to the callback function concept, the Node.js application output the data in blocks. Thus, the user receives the data more easily and is ready, as it does not have to wait for the entire operation to complete. It cuts down the overall time needed for processing, E.g: while uploading audio or video files. They never buffer any data.
Caching
Node.js holds a pretty good advantage of caching. It supports the caching of modules. When a Node.js module is requested for the first time, it is cached into the application memory. We will not be required to re-execute the codes as caching allows the application to load the web pages faster and respond with ease to the user.
License
Node.js is licensed under MIT license.
RESPONSIBILITIES
Below are some of the responsibilities a Node.js developer is expected to assume in their position :
- 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.
- Developing high-performance applications by writing testable, reusable, and efficient code.
- Implementing effective security protocols, data protection measures, and storage solutions.
