Keeping React and WordPress sane in hybrid stacks

Hybrid stacks—classic WordPress for content plus React for interactive product UI—are common in agencies and product teams. The failure mode is two apps fighting over state, duplicated business rules, and mystery data flowing through globals.

Pick one source of truth for data. Prefer the REST API, custom endpoints, or GraphQL with clear schemas over ad-hoc AJAX handlers scattered across themes. Frontend code should consume documented contracts, not scrape the DOM.

Isolate the build. Bundle React with a predictable entry (Vite or similar), enqueue assets intentionally, and avoid leaking dozens of script tags into every page. Critical CSS and code-splitting keep editor and public views fast.

Respect WordPress roles and capabilities. UI affordances must match server checks. Never trust the client for permissions; mirror authorization in PHP on every mutation endpoint.

Done well, WordPress remains a strong editorial and admin backbone while React handles dense interfaces—without turning the stack into a maintenance science project.
