Target option is required
Error message
Target option is required
What it means
GrapesJS's ComponentDrag (drag/move logic for canvas components) requires the caller to pass a `target` in its options; the target is the component being dragged and is used to resolve the document and guide rendering. If `opts.target` is missing the class cannot operate, so it throws immediately before configuring the Dragger.

Solutions
- Pass the component as `target` in the options: `editor.Commands.run('drag', { target: editor.getSelected() })`.
- Verify the component exists before running (e.g. `editor.getSelected()` is not undefined because the canvas has no selection).
- If you do not need programmatic dragging, use built-in drag interactions or the default toolbar instead of invoking ComponentDrag directly.
Example fix
// before
editor.Commands.run('drag', { event });
// after
const target = editor.getSelected();
if (target) editor.Commands.run('drag', { target, event }); Defensive patterns
Strategy: validation
Validate before calling
const target = editor.getSelected();
if (!target) throw new Error('Cannot drag: no selected component');
editor.Commands.run('drag', { target, event }); Type guard
function hasTarget(opts) {
return !!opts && typeof opts === 'object' && 'target' in opts && opts.target != null;
} Try / catch
try {
editor.Commands.run('drag', { target });
} catch (err) {
if (err.message === 'Target option is required') {
console.warn('Drag skipped: no target component available');
} else throw err;
} Prevention
- Always fetch a live component (getSelected/getComponent) before invoking drag-style commands
- Assert options before calling internal commands
- Prefer public editor APIs over instantiating internal classes like ComponentDrag
When it happens
Trigger: Constructing/running ComponentDrag (directly or via internal commands) without `opts.target`, e.g. calling the `drag` command or instantiating ComponentDrag with `{}` or options missing the target component, or passing a target that resolves to undefined after destructuring.
Common situations: Custom drag implementations triggering the internal `drag`/`move` command programmatically without setting a target; custom UI buttons that start component dragging; tests calling `editor.Commands.run('drag')` without the required options.
