Why Is Node.js Relevant?
Node.js is a server-side platform based on the JavaScript Engine in Google Chrome (V8 Engine). Ryan Dahl created Node.js in 2009, and the most recent version is v0.10.36. The official documentation for Node.js provides the following definition:
Node.js is a framework for quickly creating fast and scalable network applications built on Chrome's JavaScript engine. In addition, Node.js has an event-driven, non-blocking I/O paradigm "which makes it" lightweight and efficient. These characteristics of Node.js make it ideal for data-intensive real-time applications operating across dispersed devices.
Node.js is a cross-platform open-source runtime environment for creating server-side and networking applications. Node.js apps are written in JavaScript and can be executed on OS X, Microsoft Windows, and Linux using the Node.js runtime.
Node.js also has an extensive library of JavaScript modules, which significantly facilitates the building of web applications using Node.js.
Characteristics Of Node.js
- Asynchronous and Event Driven- All APIs in the Node.js library are asynchronous or non-blocking. It simply implies that a Node.js-based server will never have to wait for an API to return data. After accessing an API, the server goes on to the next one, and a Node.js notification mechanism assists the server in receiving a response from the previous API request.
Very Quick- Node.js is a high-performance code execution library based on Google Chrome's V8 JavaScript Engine. The V8 JavaScript Runtime motor is used by Node.js. Hub includes a wrapper over the JavaScript motor, which substantially speeds up the runtime motor and, as a result, prepares requests within Node.js.
Single-Threaded But Extremely Scalable- Node.js employs a single-threaded architecture with event looping. The event mechanism allows the server to reply in a non-blocking manner and makes the server extremely scalable instead of typical servers, which establish restricted threads to process requests. Node.js uses a single-threaded programmer, and the same programmer can handle a significantly higher number of requests than conventional servers such as Apache HTTP Server.
No Caching- Node offers the Buffer class, which provides instances for storing raw data in a manner comparable to an array of integers, but corresponds to a raw memory allocation outside the V8 heap. The buffer class is a global class that may be used in an application without the need to import the buffer module. Node.js programmers never cache data. These programmers simply generate data in chunks.
License- Node.js is published under the License Agreement.
How To Ace Hiring The Perfect Node.js Resources
And, if you already know that Node.js is a great choice, let's look at the aspect of locating and recruiting the best individuals to carry out your concept.
Following the suggestions listed below will assist you in doing this.
- Specify Your Requirements: When presenting your vision for your future application, be as precise as possible. It will assist you in developing a list of criteria that will restrict your search to the developers who actually possess the necessary set of abilities.
Node.js developers should have the following skills:
- Knowledge of the Agile and Scrum Techniques.
- Understanding of procedures such as Continuous Integration and Code Review.
- Potential of creating unit and integration tests.
- Experience in front-end technologies.
- Productivity in code writing and thorough understanding of Git and GitHub.
Not to mention expertise with relational and NoSQL databases, asynchronous programming, and a strong understanding of Javascript, HTML, and CSS. The list of such criteria could be longer or shorter depending on what you need and want.
2.Find the Ideal Solution: You've accurately outlined the concept as well as a budget for its development. Now it's time to find dedicated Node.js developers that are worth your money. You have four primary options to choose from:
- In-House Employees
- Freelancers
- Consulting and Development Agency
- Utilizing one of the online app Development Tools
Hiring in-house staff appears to be a good option at first look, right? Someone will always be there in the workplace if you need to address any concerns or new ideas, which is unquestionably a benefit of such a service. And not everyone is prepared to work remotely, which necessitates a high level of self-discipline and a solid capacity to interact with other project participants.
Hiring new workers is a high-risk, high-cost venture. In addition, other specialists, such as a project manager or a quality assurance specialist, will need to be brought on board, not to mention the requirement for more office space and brand-new office equipment.
Another thing to think about? It takes time, and as a result, it is challenging to begin the task efficiently. And, if speed is your top goal, consider how long you can wait before the recruiting process is complete.
The job market for IT specialists is exceptionally competitive. It is far from ideal for the recruiting party, as it is difficult to discover the proper personnel when working under time limitations. Securing a hire is only the beginning of the process since developing an excellent organizational and product delivery culture is a challenging effort that diverts valuable resources from the product itself.
Hiring freelancers vs. Development Consulting Firm
Money is a crucial consideration when making a choice, but is it the most important? Let's look at the expense from two angles: short-term and long-term.
Shortly, it is evident that the services of a freelancer will be less expensive. But what about in the long run? Assume you wish to add one or two new features to your application. Once a freelancer's task is over, he will seek other possibilities. This implies you'll have to look for and recruit someone else.
Hiring a development consulting firm, on the other hand, is more expensive at first. Still, you will have a guarantee that they will create a high-quality application that will function properly.
Freelancers often have a set of specific talents that span one specific area, whereas an agency includes a collection of skilled experts in a variety of disciplines. These specialists remain abreast of technological changes and advancements and will be able to tailor brand-new solutions to your specific requirements.
While freelancers work alone and without much assistance, an agency team includes project managers and QA specialists who improve the final product's quality.
This enables the agency to use many excellent programming practises in their work; things like code review, code quality rules, and appropriate testing are considerably more difficult to achieve when working with a freelancer.
Examine their prior work before acquiring Node.js developers
Whether you know exactly what you want to construct, make sure to ask the freelancers or development consultancy with whom you want to collaborate if they have done something comparable. Check up their website, prior projects, and clientele if you haven't already. You can also ask them if they can show you written recommendations.
Examine the technical abilities of Node.js Developers
Check their battlefield talents if that isn't enough for you to decide who to recruit. Include them in a current project, or assign them to a specific task or mini-project. It will demonstrate how they work and whether or not they can manage deadlines. If you're short on time, it's a good idea to see how Node.js developers might tackle an issue you've previously addressed. They may be able to anticipate the difficulties you've already dealt with and provide solutions, demonstrating their commercial understanding and grasp of the project's requirements.
Soft Skills apart from Coding
1.Communication Skills- And I'm not referring to interacting with a computer. Interacting with other team members or clients is an important component of the job, even if it is not evident. It assists the freelancer or team in understanding your needs and avoiding time and money waste.
2.Error Solving Capability- It is critical since difficulties will arise sooner or later. A good developer's ability to solve errors efficiently and rapidly is a distinguishing feature.
3.Passion for Knowing New Things- Being a developer is a never-ending adventure. And if the developer doesn't keep developing his abilities, he'll never go anywhere.
4.Proactive Way of Thinking- Being forthright about any doubts or comments they may have about the proposed solutions They should feel at ease submitting ideas and suggestions for improvements.
Conclusion
You now understand how to locate Node.js developers who will meet your company's requirements. Nonetheless, recruiting is a time-consuming and difficult procedure. Collaborating with a vendor will alleviate your suffering and allow you to focus on your primary business responsibilities rather than handling operational ones.
Finding the appropriate individuals or making a business choice will become simpler with time, but you will still have uncertainties. Articles like the one you've just read are designed to point you towards the correct path.
