Node.js Careers

As more and more software applications are being designed to run outside of the space of a web browser and the Internet of Things becomes a more significant part of our daily lives, the demand for skilled JavaScript programmers who know how to use Node.js is only going to increase. Since Node.js is a JavaScript framework rather than a programming language in and of itself, developers will need to be at least versed in JavaScript to find work as a programmer (and actually to learn Node.js). Still, they will also need to learn other important JavaScript libraries and frameworks like React, Express.js, and MongoDB. However, for these specialized programmers, a wide variety of career options are available, such as

JavaScript Developer: JavaScript Developers are specialized Software Engineers who focus on developing web applications and software using JavaScript. While they primarily work on web browser applications, those who use Node.js extensively will be working on applications that allow devices to access JavaScript programs without needing to access a server or browser directly. These developers will be working heavily on the developing technology that undergirds the Internet of Things, such as smart devices and digital assistants. This rapidly expanding career field offers JavaScript Developers the opportunity to work on cutting-edge projects across a wide range of industries.

Front-End Developer: Front-End Developers are tasked with building and maintaining the client-facing side of a web application. This includes both its visual qualities and its functional qualities. This means they will use programming languages like HTML/CSS and JavaScript to program functionality into web assets. They will also utilize Node.js to build the aspects of a webpage that frequently update and consult with server infrastructure without prompting, such as a chat function or a push notification function. These developers will be less directly focused on specializing in things like Node.js, but they will still use it as part of the projects they are working on. 

Project Managers: In the modern web development world, very few projects are undertaken by individuals. Only very small firms and companies contract web development projects to small teams. Instead, software and web development projects are usually being worked on by dozens or even hundreds of individuals in teams specializing in specific aspects of the design project. The project manager's responsibility is to oversee these teams. Successful project managers need to know how to use their teams' tools, including Node.js and JavaScript on many projects. In addition, Project Managers will need to learn the soft skills necessary to manage the human element of a given project to ensure that it is completed on time and within budget.

How to Learn Node.js

Interested in learning Node.js? There are a few different paths that you can take to acquire these skills. The primary point to consider is that Node.js is rarely taught on its own in live instruction courses. While it is an essential library, it is still a library of JavaScript, meaning that it is most often taught in the context of JavaScript instruction. Anyone who needs to familiarize themselves with JavaScript will want to enroll in a Node.js development class, and those who just want to learn Node.js will want to find a targeted training course.

Anyone interested in an immersive JavaScript education covering Node.js should consider a live instruction class. These classes are taught by expert instructors and available both in-person and live online instruction. These courses are the best place to receive a comprehensive JavaScript education, as they allow the chance to work hands-on with real-world projects and students can interact directly with their instructors to receive feedback and assistance. 

Students learning in-person will benefit from the structure and design of a classroom learning environment and the presence of a cohort of like-minded peers. They will be able to filter out distractions and learn directly from an experienced instructor in the room with them. They will also be able to take advantage of an on-site computer lab. They will, however, be restricted to locations they can commute to regularly and need to commute. Online students will be able to learn Node.js from the comfort of their homes, and they will be able to bypass the commute. They will have to supply their technology and won’t work alongside other students.

Those interested in targeting their education and learning only Node.js will want to ensure they are incredibly comfortable coding with JavaScript. Node.js is not trivial to learn, and people who aren’t comfortable with JavaScript may have issues. However, confident learners may wish to consider an on-demand Node.js course. These asynchronous courses let students learn skills like Node.js on their own schedule. This makes them ideal for people looking to learn at their own pace and for those looking to target a specific skill like Node.js. The drawback is that these classes lack live instructors, so participants must find other means of addressing any difficulties that may arise during their training.

Noble also offers free introductory seminars and resources for people who aren’t certain that learning Node.js is right for them or want to get a general feeling for the program before enrolling in a larger training course. On their official YouTube page, you can view a free tutorial seminar, Intro to Node.js. In this video, you will receive an introductory overview of the functions and applications of Node.js, preparing them for more immersive study in a JavaScript training course. Noble also has a collection of resources and articles available at their Learn Node.js Page.

A Brief History of Node.js

Ryan Dahl developed Node.js in 2009 as a framework library for Linux and macOS devices. It was developed to address limitations in the then-premiere cross-platform web server framework application, Apache HTTP Server, which was limited in its ability to handle large amounts of concurrent connection requests. The library went public in 2010 and was made Windows-compatible in 2011. Since then, Node.js has received regular updates to keep it up-to-date with Google’s V8 JavaScript engine.

Comparable JavaScript Frameworks

While some other coding libraries and frameworks provide the same functionality as Node.js, the ubiquitousness of JavaScript and its uptake in the corporate world makes it less than ideal to try and find an alternative framework to replace Node.js training. However, Node.js isn’t the only important JavaScript library worth learning. While it will ultimately benefit JavaScript Developers to learn all the critical frameworks, picking which to learn first and which to prioritize is an important decision.

React is the most utilized JavaScript library currently available. Using React, developers can build reusable, stable component pieces of code that are easily modifiable and replicable. These blocks of code, called components, let developers work faster and more efficiently on JavaScript projects, making React an incredibly popular library, especially in the field of mobile application development.

Express.js is a skill that is closely related to Node.js. Express.js lets developers build the infrastructure that manages the data flow that enters and leaves an application. It is also helpful for building the middleware that sorts and processes data requests from an application. If you want to build APIs in JavaScript or in Node.js applications, you’ll need to learn Express.js.

Most JavaScript training courses will also teach students how to use MongoDB, an object-oriented programming framework for building and organizing databases in applications running Node.js. Like Express.js, this is often taught alongside Node.js to create more well-rounded JavaScript Developers. 

Whether you want to learn Express.js, MongoDB or React, Noble has course options available for you. They also offer a comprehensive JavaScript Development Certificate program in which you can learn all these frameworks alongside JavaScript and Node.js.
