Which form engine?

About this documentation

This site is an implementation-specific reference for @openmrs/ngx-formentry (opens in a new tab), the optional Angular Form Engine used by O3 distributions that explicitly include @openmrs/esm-form-entry-app.

Which workflow should I use?

React Form Engine
Authoring workflow

Edit JSON and test in that Angular-enabled distribution; there is no supported current visual builder
Documentation

Existing deployment of ampath/ngx-openmrs-formbuilder

Form renderer
Legacy builder and its bundled preview
Authoring workflow
Legacy workflow retained for maintenance only

Pages labelled Archived AMPATH Form Builder

The O3 Form Builder that ships with the Reference Application targets and previews the React Form Engine. Its preview does not validate Angular runtime behavior. The archived AMPATH builder also does not target the current Angular engine and must not be treated as its supported visual builder.

Shared schema, different implementations

Both engines consume forms based on the standard O3 form schema (opens in a new tab). Conformance to that schema establishes a shared document structure, but it does not guarantee that every field type, expression, validation rule, data source, or payload behavior has parity across React and Angular.

Use the canonical O3 guide for the default React workflow. Use these pages only for Angular behavior, and verify each form in the engine that will render it in production.
