Gutenberg Block Development for Modern WordPress Sites
Custom Gutenberg blocks, block patterns, and reusable widgets — built with @wordpress/scripts, theme.json, and React, so editors get the simple UI and developers get clean, maintainable code.
Why Choose My Gutenberg Block Development Service?
What You Get With My Gutenberg Block Development
Custom Blocks (Static & Dynamic)
Static blocks for marketing layouts, dynamic blocks (PHP render_callback) for live data — pricing tables, post lists, calendars, integrations. Every block ships with block.json, attributes, supports, and an icon — so it integrates cleanly with the WordPress Block Library.
Editor UX & InspectorControls
Polished sidebar controls — color pickers, range sliders, toggles, range controls, and conditional groupings — built with @wordpress/components. Editors get a confident, intuitive UI; developers get a single source of truth for block configuration.
Block Patterns & Templates
Pre-designed page sections (hero, features, pricing, testimonials, FAQ) registered as block patterns and inserted with one click. Optional FSE block templates and template parts so a content team can spin up new pages without touching code.
theme.json & Design Tokens
A single theme.json defines color palettes, font families, font sizes, spacing scale, gradients, and layout widths — and every block consumes those tokens. Designers tweak the system, every block updates instantly, no CSS rewrites.
Accessibility & i18n
Blocks ship with semantic HTML, ARIA where appropriate, focus-visible states, and keyboard support. Strings are wrapped with the @wordpress/i18n package for translation, and RTL languages are tested. WCAG 2.1 AA compliance is the default, not an afterthought.
Performance & Asset Loading
Per-block enqueueing through block.json so visitors only download CSS/JS for the blocks actually on the page. Inline critical CSS for above-the-fold blocks, deferred non-critical JS, and small bundle sizes — your Core Web Vitals stay green.
Build Pipeline & CI
@wordpress/scripts for compilation, ESLint + Prettier for code style, Jest for unit tests, GitHub Actions for build/test on every push, and a versioned npm-style release process. Your block library scales as the team grows.
Migration From Page Builders
I help teams migrate off Elementor, Divi, WPBakery, or Beaver Builder — auditing existing layouts, building equivalent block patterns, and writing migration scripts so existing content survives the move with formatting intact.
My Gutenberg Block Development Process
A design-first, content-team-friendly workflow.
Block Audit & Roadmap
I review your existing site or designs, identify reusable patterns, and produce a written block roadmap — what gets built as a block, what stays as a pattern, and what stays in core. The output is a prioritized backlog with effort estimates.
Design Tokens & theme.json
I define the color palette, type scale, spacing scale, and layout widths in theme.json. Every block built afterwards consumes those tokens, so a single design tweak cascades across the whole library — no hunting for hardcoded hex values.
Block Build & Editor UX
Each block is built with block.json, attributes, supports, and React editor components. I pair-program with your design lead so the editor UX feels obvious, not just functional. Every PR includes a Loom walkthrough for non-developer reviewers.
Patterns, Templates & Docs
Reusable block patterns (hero, features, FAQ, CTA), FSE block templates, and a written content-editor guide so your team knows when to use each block. Optional Storybook page documents every block visually.
QA, Accessibility & Release
Cross-browser tests, axe-core accessibility scans, RTL checks, performance profiling, and a final UAT pass with content editors trying real workflows. Versioned release packaged as a child theme or plugin.
Iterate & Extend
Optional retainer adds new blocks per month, refines existing UX based on editor feedback, and keeps the block library current with new WordPress versions. The library compounds in value over time.
