Node.js is mainly one of the most used tools within developments that use server-side JavaScript. It is a programming environment that includes numerous libraries prepared for use by developers. Its goal is to always allow a developer to build highly scalable applications and write codes that handle tens of thousands of simultaneous connections on a single physical machine. An application is mainly scalable when it supports a load increase and does not have to be programmed again for it. For example, a scalable application must be able to adapt to an increase in the number of users it must easily support an increase in the size of the data it handles and it must be able to be maintained.
Why do you need a Node.js developer?
A Node.js developer can always create all kinds of things, web applications, command-line applications, scripts for systems administration, all kinds of network applications, etc. The speed of development is one of the advantages of this tool. Technically a Node.js developer can manage the exchange of data between the server and the users, can develop all the logic of the server-side, defines and always maintains the central database with the guarantee of high performance and responsiveness to the Front-end requests. It always integrates the front elements built by other developers working on the project.
Responsibilities of a Node.js Developer
Writing and reusable, verifiable and efficient code.
Design and implementation of low latency, high availability and good application performance.
Implementation of security and data protection.
The integration of data storage solutions can always include databases, key-value stores, blob stores, etc.
Competencies and qualifications of a Node.js Developer
Strong knowledge of JavaScript or Coffee Script mainly depending on its battery technology.
Experience in the Node.js tool and its available frameworks, such as Express, Strong Loop, among others, depending on the battery technology.
Understanding the nature of asynchronous programming, its peculiarities, and its solutions.
Always good understanding of template languages on the server, such as Jade, EJS, depending on the stack technology.
Having a good understanding of server-side CSS preprocessors, such as Stylus, Less, depending on the stack technology.
Basic knowledge of front-end technologies, such as HTML5 and CSS3.
Understanding of all accessibility and compliance with security, depending on the specific project.
User authentication and authorization among multiple systems, servers, and environments.
Integration of multiple data sources and databases in a single system.
Mainly understanding of the fundamental design principles behind a scalable application.
Always understanding the differences between multiple distribution platforms, such as desktop versus mobile and production optimization to match the specific platform.
Creation of base schemes and business support processes.
Mainly the implementation of automated testing platforms and unit tests.
