FormEngine 7.15.0

April 1, 2026

Overview

FormEngine 7.15.0 adds optional callbacks when the designer or preview language changes, extends onFormElementAdd with the preset name when a component is added from a preset, and fixes preset display in the component palette. The public FormEngine example on GitHub now demonstrates IndexedDB-backed form storage. This release also migrates several repository and sample-app scripts to TypeScript and includes dependency updates across the monorepo and examples.

Why update

• React to builder and viewer language switches with onBuilderLanguageChange and onViewerLanguageChange.
• Read presetName from onFormElementAdd when users add components from presets.
• Avoid misleading “InternalError” labels for presets in the component palette.
• Align the public example with the documented form storage workflow.

Key features

• Added onBuilderLanguageChange and onViewerLanguageChange on FormBuilderProps.
• Added optional presetName to the onFormElementAdd payload (see Tracking component add and remove events).
• Updated the public FormEngine example to use form storage (IndexedDB) alongside the designer.
