API — Website Builder — 57 abstractions. Page and redirect event handlers and use cases.
api — 21 abstractions.
api/webhooks — 15 abstractions.
Admin-side architecture patterns for Webiny extensions. Use this skill when building frontend features with headless features (UseCase/Repository/Gateway), presentation features (Presenter/ViewModel/hooks/components), MobX-based presenters, RegisterFeature, and Admin BuildParams. Covers the admin/ directory structure for both features/ and presentation/ layers.
Building forms with the FormModel system — field types, renderers, layout, validation, conditional rules, computed fields, and dynamic zones. Use this skill when the developer needs to define form fields with the builder API, choose renderers, build layouts with tabs/rows/separators, add validation (Zod or imperative), use conditional visibility/disable rules, create computed fields, or work with object fields and templates (dynamic zones).
Covers the PreviewUrlModifier extension point in Website Builder. Use when a user wants to inject custom query parameters into live preview URLs — e.g. signed tokens, tenant identifiers, feature flags — from their Webiny project. Handles the full registration pattern: implementing the interface, wiring via createFeature + RegisterFeature, and registering via webiny.config.tsx. Supports async modifier methods (e.g. remote token fetch).
Covers how to configure the maximum allowed size of the Webiny API Lambda bundle using the Infra.Api.MaxBundleSize extension in webiny.config.tsx. Use when a project's API bundle exceeds the default 4.5 MB limit or when you want to enforce a stricter limit. Handles the extension syntax, byte calculations, and interpreting the build error message.
