how to become a web developer

The web is more than 20 years old and there is a lot of web developers working on it now. The term “Webmaster” has all sorts of meanings, from developers, designers, database administrators, and web system administrators. Today, we see more and more aspects of depth in the field of developing web as developers of front-end, the developers back-end, experts DevOps and type developers “full-stack” meaning made from AZ.

The specialization of each specific area for the web shows that the web is becoming an essential and extremely large platform. The site is a very important part in the world economy and the web itself is not a small role in the ingredients constituting it as the design, development and maintenance.

But with such specialization, and the rapid growth of the web, it also opens up opportunities for many people. In the past few months, many people are looking to move from other professions to becoming web developers , and those who are developing web continue to want to dig deeper and wider through other areas of the web. Web development clearly opens up job opportunities for many people as more and more companies need web-specific skills. Even if you’ve mastered an in-depth web development skill, you can even start your own online startup.

But it is a fact that web developers do not necessarily know exactly what platforms or even where to start work. Therefore, the article briefly describes the basic factors if you are interested and want to enter this field.

If you are a fullstack web developer, from AZ you should at least know web technologies such as: Linux, databases, server languages ​​and frameworks, client technologies such as HTML, CSS and JavaScript.

If the above, each of you know a little bit, then you can create your own web application. However, you need to dig deeper, add a few more sections on web technologies, to give you an overview, thereby directing you to a specialized area of ​​web development. Or if you are still interested in all areas of the web, that’s fine, as long as you know all the “nooks and crannies” to be able to develop a good web application.

Linux and servers

Everyone is familiar with the Windows operating system, but knowing Linux is very important because Linux has a lot to do with the web. Not because many traditional servers run Linux but virtualization technology is increasingly stable and popular, using systems like Vagrant, which is an open source system for you to develop a virtual machine and then use the virtual machine itself. to run the application.

But in fact, it is not necessary to understand the Linux platform thoroughly to be able to develop a good web. But you need to understand some Linux basics, like directories, accounts and user rights, and how to install programs. You also need to know where the system log files are stored, both the general log file and the log file generated by the HTTP server.

If you’re new to sysadmins on Linux, learning about systems like DNS, SMTP, and SSL won’t help much, but make you more confused; Right now the company tries to rely heavily on 3rd party tools as much as possible.

Knowing how to use classic UNIX-based word processing tools like Emacs or Vim will help a lot, even if you’re someone who prefers a GUI over the command line. And of course, knowing more about UNIX I/O tools like grep and find would help a lot.

You should also not pay too much attention to virtualized systems and containers, not because they are unrelated, but because they will confuse you, making your learning process more complicated. Those things you can slowly grasp later. If you decide to use Vargant, Docker or Amazon Web Services, you can focus on learning the technologies of these services separately.

Linux is a very complex and intensive system. It can take a person years to understand and master the entire Linux system. At first, Linux may be strange and difficult, but over time, you will customize the environment, learn how it works and then become more comfortable with it.

Database

There is no constraint that a web application must have a database. However, in reality, it is very rare that modern web applications do not use a database. Nostalgic developers still prefer to use traditional, tightly coupled databases like SQL and many web applications still use today. However, it should be recognized that a certain standard has its ups and downs, and SQL databases can also be going down.

It is for this reason that many people start web development with so-called NoSQL databases like MongoDB, which allow you to save complex documents in an object-oriented format and current programming language. without having to create overhead for SQL queries. If you feel SQL is too complicated, why not think in the direction of NoSQL?

However, there is a reason that a tightly coupled database like SQL is still popular, because it has more than 40 years of research, application and especially bring many benefits. It’s still well worth the effort if you take the time to delve deeper into such a tightly coupled database, especially when you’re using high-level languages ​​and an ORM (object-bound) object manager. relational manager) to handle most queries. The long-term benefit when you master SQL and linked database systems, the flexibility of the linked database is still “unmatched”.

Of course, this does not mean that NoSQL is nothing. MongoDB, the newer PostgreSQL makes it very easy for web developers to store and extract JSON objects, and they are very efficient.

Programming language

Next is the most important but also the most controversial choice in the developer community, which is the server-side programming language. The article does not state which is the best language, but there are two programming languages ​​you need to care about: Python and Ruby, not purely because they are good in themselves, but also because the Flash and Sinatra frameworks are simple and powerful. , has specific instructions for use and has a large community. You can create amazing web apps with these two frameworks, or you can combine various packages to work towards the Django and Rails frameworks, opening you up to many new possibilities for app development.

The strength of Ruby and Python is not only in their ability to do, but also that this is a language that is easy to grasp for beginners.

Another option that is growing in popularity is JavaScript, which often uses node.js, and is said to be the ideal language for both ends: client (browser) and server. Node.js is not a great framework but many people use it nowadays. Therefore, JavaScript is increasingly popular in web programming for mass applications and for beginners.

There are also other options, like PHP which is easy to learn and has a large community. However, PHP is unimpressive and doesn’t “appear” to be a language. The truth is that WordPress currently accounts for 10% of the web on the internet today, so PHP is still around. In addition, there are many opportunities to explore new areas within the WordPress ecosystem.

Depending on your development background, experience and preferences, you may want to try some other languages ​​like Go, Scala or Clojure, all of which are used for web application development and have a supportive community. widely supported.

In short, if you already know a programming language, you should try to take advantage of it for web development. If you’re not comfortable with the language you’ve learned, try Python or Ruby. They are easy to learn, have many users and have a large ecosystem, many frameworks to meet the application scale. Of course, the decision is up to you, maybe you don’t like the two languages ​​above but want to follow a certain “unique, strange” language, that’s OK. Learning to be a real web developer is generally much harder than learning just to develop web applications in a new language or with a new framework.

Front-end

Over the past decade, the front-end in web development has become increasingly important. HTML, then CSS, and combine HTML5, CSS, JavaScript, and multiple APIs to create a front-end interface that’s vital to the web application development process.

You don’t have to know all of the above to be able to develop front-end. But you need to know a little about HTML as well as basic CSS. Better yet, you need to learn more JavaScript, though how much you learn depends on how complex the web application is.

Perhaps the biggest push in front-end development over the past few years has been the introduction of front-end frameworks like Zurb Foundation and Twitter Bootstrap. These frameworks help you focus on the design you want, overcoming problems other people have had before without them. Like Bootstrap can save you a lot of time, help you focus more on the design than sitting around editing the code. However, Bootstrap and Foundation don’t mean you don’t learn CSS, but they just reduce the amount of CSS you need to get your website running.

JavaScript also benefits in part because web applications are getting more and more complex and because everyone has a JavaScript development environment, which is a web browser. The number of modules and packages for JavaScript is extremely large and shows no sign of stopping. Ember.js and Angular.js thrive to encourage developers to use. At the same time, front-end frameworks are often too complex for a novice programmer. Although jQuery is quite old, it still has a great JavaScript library that makes it easy to generate DOM for cross-platform.

JavaScript is still a very important skill for any web developer.

V whoa should start from?

The good news is that web development is so broad, it’s hard to make a wrong choice because there’s no such thing as “adding one end to another”. Because no matter what you choose, there is always a huge community using the same technology ready to assist you.

If you don’t know anything yet, try Python with Flask framework, PostgreSQL database, Bootstrap framework with jQuery.

If you feel like object-oriented programming or want a little more flexibility in coding, you can learn Ruby with the Sinatra framework, which includes PostgreSQL, Bootstrap, and jQuery.

Finally, developing WordPress is a great way to step into its own ecosystem.

Conclude

Sometimes it seems that software development is turning into web development. It may seem like an exaggeration but it is clear that the market has a huge demand for web developers. No matter what programming language or technology you learn, it’s important to learn the web mindset and try to figure out what’s going to make this industry go forward so that you can “scratch” it. the right place to itch”.
