Node.js is a programming framework – basically, a JavaScript extension – which turns a narrow focus specialized JS language into multipurpose solution. Usually, Node.js is used for the backend development.

Notice that the basic engine of the discussed framework - V8 - is its crucial beneficial factor that affects the performance of applications in a most positive way. So if you are planning to create a really 'reactive' app with complex business logic, which wouldn't lag while executing it (particularly, during the processing of 'client-server' requests), Node JS would be your best choice. Moreover, due to the universal templates for realizing standard functionality, the built-in packages manager NPM allows for developers to focus their performance on the development of specific functionality and construction of a software solution first-hand. Lastly, Node.js is one of the most renowned tools employed in the API development.

Moving on, the discussed platform enables one to use the same data on different levels (provided one is working with an MVC or MVVM framework, like Express.js, Koa.js or Sails.js). This means that given framework is a perfect solution for collaborative work because it provides the capabilities for the creation of a perfectly-structured project that will eventually be easy to support and scale.

The listed advantages should be enough to answer the 'why hire Node.js developers' question and make you see how much your staff requires a dedicated specialist with high qualification. The other thing is that it isn't so simple to hire Node.js programmers. Below, we give you a list of responsibilities and requirements the potential employed specialist must meet.

Additionally, programmers specializing in Node.js, work through the mechanisms of apps' server part interaction with user interface.

The formulated standard list of responsibilities usually assigned to Node.js developers by IT organizations looks in the following way:

  • Node.JS programming;

  • fast & efficient analysis of client requirements;

  • server logics processing;

  • interaction with software components created by other developers;

  • implementation of interaction with database management systems & other autonomous data storages;

  • working through data protection mechanisms & the application performance;

  • optimization of app's functionality to increase its performance speed;

  • composition of a readable code that can be used for new software projects further on;

  • work in a team.

Now, a few words about the cost to hire a Node.js developer. Basically, the cost depends heavily on the experience, working conditions and potential employee's location (particularly, asking yourself: 'Where to better look for Node.js developers?', remember that the experts from Eastern Europe offer the best service price to quality ratio). According to practice, even juniors at the start of their career ask for at least 500 c.u. per month.
