The material will be of interest to beginners who seek to connect their lives with Node JS development services. You need to get basic knowledge about the operation of a computer, browser, website. You can take some basic computer science course, something that is studied at school. Master the basics of any programming language (C, C++, Python) to understand what a variable is, language constructs, functions.
HTML is a markup language (not programming). From there we start learning web development.
CSS – Cascading Style Sheets. If HTML is a bare and boring wireframe, then with CSS our pages start to look nice and stylish. Having mastered these two technologies, we can already create the first projects. Simple landing pages or business card sites.
· Version control system Git
The created projects need to be stored somewhere so that you can share the source code, see when we created it and how we changed it. Git is the perfect solution as it is the most popular version control system.
JS is the main programming language on the web and for front-end developers in general. Its study and practice will take more time. And along with this, having mastered the JS core, the study of any libraries and frameworks will not be significant problems.
Since CSS is just style sheets, we can’t talk about any variables, loops, or functions. To do this, you can use the preprocessor: Sass, Less or PostCSS. They give us the ability to use variables and mixins (sort of like functions). This code is then “compiled” to plain CSS.
The choice is great: Bootstrap, Material, Tailwind , Compass and many others. Ready-to-use component sets, global styles, and the ability to customize for any project.
This knowledge and technology are already enough to create full-fledged business card sites, landing pages and other simple sites with several pages. Of course, this is provided that we do not write the Back-end, all the data has already been prepared for us.
· Regular Expressions
Regular expressions are always a problem. No matter how much we teach them, we still do not really know. The sooner we get to know each other, the sooner we’ll learn how to use them. Most often used in Front-end for form validation.
Object Oriented Programming
Object oriented programming is a classic. If you miss understanding the principles of imitation, polymorphism, and encapsulation, you will create a lot of problems for yourself when working with TypeScript or more complex JS programs.
It doesn’t matter if your application is running or crashed for some reason – all this should be recorded in the logs. They come in handy when looking for bugs. You can set up notifications to learn about performance problems from special monitoring systems, and not from your clients.
In addition to cleanliness, your code must be secure. View the TOP 10 OWASP Rules. Well, do not offer to configure the HTTPS protocol and check CORS.
· Design and Development principles
There are several coding principles to master: KISS, SOLID, YAGNI, DRY. These principles are often asked in interviews – show your best side. Each of these principles also implements clean code practices.
Continuous integration – we regularly measure our code in the repository, after which tests, linting, build and any additional steps are automatically run. We are sure that our changes did not break the project.
