React API reference

All supported JavaScript exports are available from form0-react unless another path is shown.

Rendering

• FormRenderer — render and manage a schema-driven form.
• ThemeProvider, ThemeContext, useThemeClass — provide or read the active theme class.

See FormRenderer and Themes and styling.

Field registry

• FieldRegistryProvider, FieldRegistryContext, useFieldRegistry
• createFieldRegistry, defaultFieldRegistry
• registerFieldComponent, unregisterFieldComponent, resetFieldComponents
• getFieldComponent, listRegisteredFieldTypes, getMissingFieldComponentTypes
• KNOWN_FIELD_TYPES

See Custom field renderers.

Schema utilities

• cloneDeep(value) and cloneSchema(schema) create detached copies.
• ensureSchemaKeys(elements) adds stable keys where required and reports whether it changed the input.
• prepareSchema(schema) clones a schema and ensures element keys on the copy.

Specialized integration

• useBuildingPlanController(options) coordinates the renderer’s building-plan section UI with repeatable data. It is specialized rather than a general form-state hook.

The internal useFormEngine, worker client, individual default renderer components, and FieldRenderer are not package exports. Importing internal files is unsupported by the package export map.

Theme tokens are exported separately from form0-react/theme.css.js. The compiled stylesheet is available as form0-react/index.css.
