The technology of developing websites and mobile applications is a question that interests many novice programmers and inquisitive clients who want to know the real cost of developing website and application.
You can buy website development anywhere, but how competent are the developers? Let's dig into the process of creating sites and understand what a programmer does.
The most convenient way to understand the development order of a site is to think of it as a two-way process:
• front-end part (front-end development) is a client-oriented side of a website or application engaged in programming a part of the system that is visible to users.
• the internal part (backend development) is the server part, which includes the server, server application (supported by the internal programming language) and the database.
Front-End Development
Web development is also called client-side programming. It is used to create parts of a website or application that users can see on their screens. Interface programming languages:
• HTML (hypertext markup language);
• CSS (cascading style sheets);
• JavaScript.
When creating the external interface of the program, developers use wireframes that help them save time and speed up the web development process. The most popular site development tools — the environments used in HTML and CSS — are Bootstrap, Foundation, and Stylus. There is also a significant selection of JavaScript frameworks such as Vue, Angular, Ember or Backbone.
By the way, the use of the above “process accelerators” is good, but it’s better to show the developer in an interview. More about this in the article:
Not all site development tools are good
Back-end development
Internal web development covers the selection of servers, databases, caching systems, server-side programming languages and their frameworks. In other words, this relates to that part of the program that is not visible to end users.
Servers are responsible for receiving and processing requests from user devices (laptops, smartphones, tablets, etc.). Some of the most popular web servers:
• NGINX;
• Apache HTTP server;
• IIS.
Databases are used to store, sort, search, filter, calculate and present data in accordance with requests received from the client side of the web application. Databases are important for many web services, such as e-commerce sites. They can be relational and non-relational. Typical relational databases are PostgreSQL and MySQL. MongoDB and Apache Cassandra are non-relational databases.
More than ever, web applications need caching systems like Memcached or Redis.
The caching system is used to process and reduce traffic load at the database level.
Internal or server-side programming languages are used to provide interoperability between servers, databases, and the client side of a website or application.
The goal of the role of frameworks is to provide simple and efficient coding. Some of the common programming languages (and their frameworks) today:
• Python (Django, Flask);
• Java (spring);
• Node.js - JavaScript runtime;
• Ruby (Ruby on Rails);
• PHP (Laravel);
• Rock (Play).
