CKEditor 5 model conversion with Promise
I am creating a CKEditor 5 plugin which must display a list based on the result of a REST call.
I registered my schema item with:
editor.model.schema.register('myItem', {
allowIn: '$root',
isBlock: true,
isObject: true
});
Then added the converters:
editor.conversion.for('upcast').add(upcastElementToElement({
view: {
name: 'div',
classes: 'myItem'
},
model: 'myItem'
}));
editor.conversion.for('dataDowncast').add(downcastElementToElement({
model: 'myItem',
view: (modelElement, viewWriter) => {
return getContent(modelElement, viewWriter);
}
}));
editor.conversion.for('editingDowncast').add(downcastElementToElement({
model: 'myItem',
view: (modelElement, viewWriter) => {
const div = getContent(editor.model, viewWriter);
return toWidget( div, viewWriter, { label: 'widget label' } );
}
}));
My getContent method is responsible for fetching data with the REST call. My issue is that if I use axios or fetch to get the data, it returns a Promise and I don't know how to pass the result to the 'view' attribute of the object passed to downcastElementToElement method. This 'view' attribute expects a function which returns the object to display.
Is there a way to achieve that ?

CKEditor 5 doesn't support async conversion. It'd complicate the conversion and it would provide bad experience as the editor would need to be locked during the fetching. I'd suggest creating a sync conversion and then after the fetching replace it with your specific element from DB.

An example of such a feature is the image upload. A placeholder is shown until the image is uploaded so a URL to it is available. The conversion is synchronous (though it converts to a placeholder if the source is not available yet). Asynchronousity is handled separately.
