WordPress has been around for a long time, and because of that, you will find many different ways people write code for it. Some still use old tutorials from years ago, while others follow newer practices. If you are starting today, it’s better to learn the modern way instead of picking up outdated habits.
Modern WordPress development is basically about writing cleaner code, using the right tools, and understanding how WordPress works behind the scenes. This helps you build plugins, themes, and custom features that are stable, fast, and easy to maintain.
How WordPress Has Changed
Earlier, most WordPress work was done with simple PHP files, jQuery, and editing themes directly. Things were more “quick fix” style. That worked for small projects, but not for complex websites.
Now the ecosystem is more advanced. The Block Editor is built with React. Themes use a configuration file called theme.json to control colors, fonts, layouts, and spacing. Developers use Composer for organizing code and WP-CLI for automation. The REST API makes it easier to connect WordPress with other applications.
You don’t have to master everything at once, but it’s good to know that WordPress today is much more modern than what most beginners expect.
What You Should Focus on First
If you are a fresher, start with the basics. Learn PHP properly because almost everything in WordPress runs on PHP. Try to understand how hooks work (actions and filters) because that’s the core of WordPress development.
Once you are comfortable with these, you can slowly move into:
- Creating plugins
- Custom post types
- Using the REST API
- Working with the Block Editor
- Writing cleaner, structured code
You will also use some tools like Composer, Git, WP-CLI, and a local development setup. These tools are not difficult, and we will cover them step by step in the next articles.
Why Learning the Modern Way Helps
If you write modern and organized code, you will find it easier to:
- Understand large projects
- Work in teams
- Maintain your own plugins or themes
- Add new features without breaking things
- Follow professional practices
This is the style most good agencies and plugin companies follow today.
