Let us look at how to find and hire the best node.js developer to help you put your plan into action. A few top aspects given below will assist you in doing so.

Listing the Requirements

Writing out your prerequisites before you begin searching for candidates is a good idea. When you know exactly what you need to find the top prospects for your project, the entire process becomes much easier. Once you have finished outlining your project needs, find out the skills a Node JS developer should have to get started with your project.

Examine the Hiring Prospects

Once you have compiled a list of all the abilities and qualifications you are looking for in a Node JS developer, it is time to assess your hiring options. When it comes to designing mobile or web apps, you typically have three choices:

• Web development company
• In-house
• Freelancers

Employing an in-house team of developers appears to be a good idea at first because someone will be in the office almost all the time when things go wrong, or new ideas come up, which is an upgrade over the other two options.

Hiring in-house developers come at a higher cost, and you’ll have to set up your own infrastructure so they can perform efficiently. Aside from that, the process of screening, interviewing, and recruiting takes a long time. As a result, if the project pace is vital, employing in-house developers may not be the best option.

Out of the three options, hiring freelancers is the most cost-effective. However, if a project needs the engagement of numerous freelancers with varying skill sets, managing the hired remote developers will be a difficult task. 

Engaging with a web development organization is a good and usual alternative. They not only deliver the work on time but also have a developer team with a variety of skill sets. Therefore, you can rest assured that when you hire a dedicated Node.js developer, all of your project’s skillset demands will be covered. Alternatively, you can also use Freewebsitebuilder. 

Knowledge of the Front-end stack

Even though a Node.js developer’s primary responsibility is to manage your application’s backend, they also need a basic understanding of front-end technology. Backend developers can adjust the code to satisfy user expectations if they understand how backend components fuel the UI. It also increases team collaboration because everyone knows what their responsibilities are.

During the interview, you can ask applicants about their understanding of JavaScript, HTML, AJAX, CSS, front-end frameworks such as Vue and Angular, and libraries like JQuery and React. You can also inquire about their front-end knowledge by asking about the compatibility of front-end technologies that are a good fit for Node.js apps.

Examine Portfolio

One of the most important aspects to consider when employing a Node JS Developer is work experience. Reviewing a Node JS developer’s portfolio can provide you with a better idea of their skills, knowledge, and experience.

It is recommended that you should get in touch with a dedicated developer with experience in this domain. If you can’t discover someone with experience in the field, you can still look at their prior clients’ testimonies and portfolios.

Customer Testimonials

Customers’ recommendations influence the majority of purchasing decisions. Before making a buying decision, people check reviews and testimonials. Since no one wants to believe the seller’s statements, the only method for the viewers to learn about the product’s quality is to go through user reviews. 

There is no exception when it comes to website development services. It will give you peace of mind to know that your project has been employed by a respected web development company. As you will be signing a long-term contract with a web and mobile app development company, choosing one that provides long-term solutions is critical.

Customer reviews will inform you about the company’s project management experience and skills. Most significantly, it will provide you with a greater understanding of the company’s strengths and limitations and how they have handled client satisfaction. 

You should also seek testimonials on their websites and read consumer reviews on the company’s official website. Clutch, for example, is an excellent resource for individuals seeking 100% genuine consumer feedback. You can trust that these testimonials are unbiased and produced by clients who have dealt with the organization.

Usage of Application Monitoring Tools

APM tools keep you updated about all the information you need to avoid service outages, decrease performance bottlenecks, and fix memory leaks. As a result, for your Node.js project, having the correct combination of APM tools is crucial. It also includes the information you need to understand how the Node.js application performs at any given time.

Node.js professionals who have worked with a variety of APM tools can assist you in making an informed decision based on the size and scope of your project. Furthermore, the selection of the appropriate tools needs experience and knowledge of their features because of the accessibility of many options in the market, which is further due to the widespread adoption of microservices architecture.

Expert developers’ top picks for APM tools:

• The ELK Stack: Elasticsearch, Logstash, and Kibana are the three open-source projects that make up the ELK Stack. It is a straightforward and dependable tool for analyzing log files and gaining insight into program performance. The stack is primarily used to collect and analyze logs from applications, allowing for speedier troubleshooting, security analytics, and other functions.
• Prometheus: SoundCloud has developed Prometheus, an open-source tracking and alerting system. It offers multi-dimensional data collecting and queuing and the ability to store real-time measurements in a time series database.

Using many Test Runners and Tools

Since Node.js is so ubiquitous among developers worldwide, additional testing tools and frameworks are being created with it in mind.

However, selecting the correct testing tool necessitates an awareness of tool applicability based on project kind, complexities, requirements, and various other considerations. A skilled developer identifies gaps and potential dangers in the code and recommends a testing plan to improve your deployment results.

Developer-recommended testing tools to assist you in evaluating a candidate’s proficiency in testing Node.js apps: 

• Mocha is a powerful JavaScript test framework that runs on Node.js. It runs asynchronous testing on Node.js apps and is simple, quick, and extendable. Mocha is very well-integrated with Chai, a JS framework assertion library. Both Mocha and Chai support the test-Driven Development (TDD) methodology or the Behavior Driven Driven Development (BDD) methodology.
• Jasmine is a JavaScript BDD framework that does not rely on any other JS framework or DOM operations. It offers a simple syntax that allows developers to write tests more quickly.

Dealing with Various Package Managers

Node.js relies on well-tested, open-source packages to reduce the need for rewriting code and speed up development. To manage these packages, developers utilize package managers. Examine whether the applicant you’re considering hiring is well-versed in npm, the Node.js package manager. Asking developers about the numerous options for npm modules they use to achieve better results is one approach to determining their level of expertise.

For Node.js apps, Yarn is the most well-known alternative package manager. It installs packages quicker than npm by using the local cache memory rather than waiting for the download to finish. To optimize the overall network, along with the installation of software, it queues network requests.

PNPM is a different option. It is praised by developers for resolving the NPM doppelganger concerns, as it installs a single copy of all essential packages on disc and provides a direct connection to the node_modules directory for installation. This tool helps you save a lot of space on your hard drive.

Knowledge of different database ORM tools

When you are starting a medium or large-scale project, you will need an ORM (Object Relational Mapping) library to help you map objects to relational databases. ORM assists you in maintaining objects even if the access of the apps or sources changes over time because various database systems handle data differently. In the end, ORM allows you to automate database migrations. As a result, if the candidate knows how to use ORM tools well, consider them an asset.

Experienced developers’ favorite ORM tools 

• Bookshelf is a Node.js ORM JS library with a small codebase. Traditional callback interfaces, improved transaction support, and polymorphic association are all available with Bookshelf.
• Sequelize is a Node.js ORM that supports Microsoft SQL Server, MySQL, MariaDB, PostgreSQL, and SQLite.

Conclusion

Whether you hire Node.js developers India or a web development organization, whether you need a simple app or a complex app, the ultimate decision is based on the details of your project. As a result, when you hire a NodeJS developer, be sure you know exactly what you need and why you need it.
