One of the most common uses of NodeJS is backend programming. It allows you to program applications that are capable of running on the server, providing access to databases, the file system and any other server-side resource. However, NodeJS is so broad that it can be used for many different tasks, such as automation, optimisation or application deployment, among other operations.
When we refer here to websites we want to indicate sites where the most important part is the content, be it blogs, news pages, and even electronic commerce.
Single Page Applications
In recent years, the web has become famous as a platform for business applications. Applications called “management”, which were previously executed with desktop programs, today have web fronts that allow us to use them from the cloud, i.e. from any browser connected to the Internet and without the need to install software on the machine. In this type of application, it is usual to carry much of the processing load from the server side to the client’s scope. In this new paradigm, the browser is responsible for doing many more things than traditional websites, such as the creation of HTML code to visualise data or navigation between screens or routes of the application.
The two main factors that characterise the SPA, 1) the fact of bringing the raw data from the server (lighter) and 2) all the navigation is done within the same document, they produce web applications with a speedy response, providing an experience of use close to that of a desktop application.

Note: React, and Polymer are considered more libraries, but with a series of additions, which they provide in many cases, offer as many features as those found in a framework. In case someone does not know yet, a library is a set of functions, or classes and objects, that allows us to perform a range of everyday tasks for the development of specific applications needs. A framework is distinguished mainly from a library because, in addition to providing code to solve common problems, it offers an architecture that developers must follow to produce applications and ensure better code quality and greater ease of maintenance. In other words, the framework, in addition to offering different utilities, sets a style and workflow when it comes to developing applications.
The next development revolution for the Internet, which still has not finished exploding in the middle of 2017, is called Web Components. It is based on a new API (with several specifications together) aimed at creating components. The components are like new HTML tags that any developer can create to solve common or particular applications problems.
With web components developers can extend HTML by creating new components capable of doing anything and with advanced encapsulation capabilities, to respect their autonomy and to be able to be used in any project, maximising code reuse capabilities and without the need to be based on any library or framework.
Like HTML5, Web Components are offered by browsers by default, although their support at this very moment is not so universal.
Note: In the coming months, all browsers are expected to support Web Components V1, and we can use it without any restrictions. Meanwhile, there is a Polyfill that allows extending Web Components support to browsers that do not yet have it. Polyfills are literally “gap fillers”, which make up for the shortcomings of older browsers to standards. HTML5 APIs are already being used intensively to allow new features of web languages to be used in old or outdated clients.

Note: Specialisation is also present in these professions. It is incredible to see how profiles develop in the world of the web and how newly specialised professions are generated year after year. What we used to call frontend, to be sure, today we can subdivide it into dozens of profiles or specific jobs such as “front-end engineer”, “frontend web designer”, “CSS architect”, “mobile frontend developer”, “frontend DevOps”.
Knowledge of the web platform
Our second advice is that, if you are going to work in this medium, you must keep in mind each one of the particularities of the web platform. There is a lot of general knowledge that you must acquire and that will give you a base on which to base your skills in the world of development for the web.
Knowledge of the medium: You must know what is the Internet, the Web, the HTTP protocol, the system of domain names and of course the primary languages to specify the content and form: HTML and CSS.
Design knowledge: Although your profile may be more of a programmer, it is ideal to have a vision, at least technical, of the design characteristics for the web. User experience, usability, graphic design in general or accessibility are essential points.
Programming knowledge: If you are going to dedicate yourself to the programmer’s profession, it is not enough to have a basic understanding of code and structured programming, it is ideal to be interested in object-oriented programming, software analysis and design, design patterns, bases of data, etc.
Knowledge of tools: The professional must also know a large group of tools for day-to-day work, from the command line terminal and basic server administration to the automation of tasks, through the version control tools ( Git preferably) and optimisation.
Fortunately you can know or learn all these languages, technologies and tools for free with on the web, but if you want a guided learning or want a personal programming tutor for one to one coaching or to solve your Java assignments or other programming projects, we recommend you to write to us with your requirements.
