For WordPress Developers
4WP.dev is a knowledge base built on production code — not abstract tutorials. Study open-source plugins, Gutenberg block patterns, Block Editor APIs, and architecture decisions you can apply to client work immediately.
What you get from 4WP.dev
- Architecture case studies — real plugins as reference implementations (blocks, REST, settings, SEO, MCP abilities)
- Gutenberg block development — custom blocks, Interactivity API, Query Loop extensions, FSE patterns
- Modern WordPress tooling — Composer, Abilities API, MCP Adapter, WP-CLI workflows
- SOLID & design patterns — documented approaches in the Development section
- Source you can fork — every major plugin has a public GitHub repository
How to use this hub
Pick a plugin close to your problem, read its architecture notes, clone the repo, and adapt the patterns. Follow the Development track for deeper guides on hooks, blocks, and project structure.
FAQ
Common questions for WordPress and Gutenberg developers — wrapped with 4WP FAQ for FAQPage JSON-LD schema.
What can I learn from 4WP.dev as a WordPress developer?
Production-grade patterns for Gutenberg blocks, plugin architecture (SOLID, REST API, settings screens), SEO workflows, MCP abilities, and real release pipelines — all from maintained open-source code you can read and fork.
Is the GitHub source code production-quality?
Yes. These plugins power 4wp.dev and client projects. Expect Composer autoloading, namespaced PHP, block.json blocks, PHPUnit where applicable, and documented architecture in the Development section.
How does 4WP.dev teach Gutenberg block development?
Study plugin singles under /plugin/, clone repos, and follow guides on hooks, blocks, inner blocks, Interactivity API, and block bindings. Each plugin is a case study — not a toy demo.
What architecture patterns are documented?
SOLID principles, OOP, MVC, Domain-Driven Design, and software design methodologies — mapped to WordPress plugin structure with examples from the 4WP codebase in Architectures.
Can I fork 4WP code for client projects?
Yes, under GPL v2+. Fork, adapt, and ship — respect the license and attribution. Many patterns (block wrappers, REST controllers, inventory tables) are reusable starting points for commercial work.
Does 4WP.dev cover modern Block Editor APIs?
Yes — block.json, InnerBlocks, block variations, Interactivity API, block bindings, Query Loop extensions, and editor sidebar plugins appear across the suite (FAQ, Advanced Code, QL Blocks, SEO Helper, MCP Abilities).
Are there REST API and MCP integration examples?
Yes. 4WP Bundle exposes 4wp/v1 REST endpoints; MCP Abilities connects AI agents to WordPress via the Abilities API — both with public source on GitHub.
What PHP and WordPress versions do 4WP plugins target?
Typically PHP 8.0+ and WordPress 6.0+. Check each plugin header on GitHub or the plugin page for exact minimums before adopting patterns in your stack.
How is 4WP.dev different from generic WordPress tutorials?
Content is anchored in shipped plugins — real settings screens, edge cases, release history, and SEO/GSC workflows. You learn from code that runs in production, not isolated snippets.
