Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

When to use `Abstract` Base Class vs `Interface`

When devising the architecture of your classes, a few concerns will pop up:

  • How its instances are going to be used
  • Discover common properties and patterns
  • Foresee how this class is going to be extended in the future

You can leverage your implementations by using abstract base classes and interfaces. Often these two raise a lot of confusion since they are similar, however, they actually have different implementations.

Let’s find out when to use each. For this, we will see examples using different programming languages (Kotlin, TypeScript, Java), but the theory applies to all of them.


What is an abstract class?

A class can be declared abstract when you want common methods or properties to be extended by other classes (or other abstract classes).

When an abstract class defines an abstract method, this method must be overridden by the extending subclass — unless the abstract class is extended by another abstract class, in which case you’ll get a cascading inheritance.

These abstract methods, defined in the abstract class, are created having only their signature. They shouldn’t have a body at this point, that will be defined in the overridden method.

Likewise, you can define concrete (non-abstract) methods that will be inherited by the extending class.

How to use Tailwind CSS with a React App

What is Tailwind CSS?

Tailwind is a modern CSS framework. It is a utility-first-based framework and provides you with a unique set of utility classes which makes the development process very easy and results in making a unique design. Utility-first CSS is fast, robust, and very efficient making your coding hassle-free. Tailwind CSS is also not opinionated; it means you are totally free to customize the design lament and website's component.

Tailwind is a power pack of everything you need to create a website without writing any custom CSS. The main difference between Tailwind and its competitors is that it gives developers complete control over the styling of a web application.

Why Use Tailwind CSS?

There’s a lot that goes on in web development. It can sometimes, thus, become an overly complicated task. Mapping the impact of styling might become tedious and time-consuming hampering the progress of the application/website.

Implementing Tailwind CSS will eliminate all the above-mentioned issues. Tailwind CSS creates small utilities with a defined set of options enabling easy integration of existing classes directly into the HTML code. Custom styling can be provided to the components with the help of this framework.

Tailwind CSS: Pros and Cons

Tailwind CSS: Advantages

  1. Control Over Styling
  2. Faster CSS Styling Process
  3. Responsiveness and Security
  4. Additional Features

Tailwind CSS: Disadvantages

  1. Styling and HTML are Mixed
  2. It Takes Time to Learn
  3. Lack of Important Components
  4. Documentation

In this blog, we’ll demonstrate how to make Tailwind CSS work inside your React project without having to eject Create React App.

Using Tailwind CSS in your React App

First, open your terminal and type the following commands to create a new project.

#using NPX
npx create-react-app tailwindreact-app

#using NPM
npm init react-app tailwindreact-app

#using yarn 
yarn create react-app tailwindreact-app

create-react-app is the official React build tool for scaffolding new React projects. It leverages webpack and babel and reduces the hassle of configuring and setting up the build processes for projects, allowing you to focus on writing the code that powers your app.

Next, install Tailwind and its dependencies:

cd tailwindreact-app

npm install tailwindcss postcss-cli autoprefixer -D

We need to initialize Tailwind CSS by creating the default configurations. Type the command below in your terminal:

npx tailwind init tailwind.config.js --full

This command creates a tailwind.js in your project’s base directory; the file contains the configuration, such as our colors, themes, media queries, and so on. It’s a useful file that helps with predefined sets of properties which will aid the need to re-brand certain conventions or properties if the need arises.

Now update tailwind.config.js:

module.exports = {
  content: ["./src/**/*.{js,jsx,ts,tsx}"],
}

How To Configure PostCSS?

The PostCSS documentation states that:

“PostCSS is a tool for transforming styles with JS plugins. These plugins can lint your CSS, support variables and mixins, transpile future CSS syntax, inline images, and more.”

Why Autoprefixer?

It’s necessary to install Autoprefixer alongside Tailwind CSS because Autoprefixer usually tracks caniuse.com to see which CSS properties need to be prefixed. Hence, Tailwind CSS does not provide any vendor prefixes. If you’re curious as a cat in regards to PostCSS navigates to their documentation.

Create a PostCSS configuration file in your base directory manually or using the command:

touch postcss.config.js

Add the following lines of code to your PostCSS file:

const tailwindcss = require('tailwindcss');
module.exports = {
    plugins: [
        tailwindcss('./tailwind.config.js'),
        require('autoprefixer')
    ],
};

Because PostCSS is necessary to lint our CSS, hence this configuration.
