AdminJS how to make field mandatory

I have been looking for a long time and I have no idea how to do it, do you have a simple solution to make a field mandatory in the action/new or edit pages ? Thanks

You need to add isRequired:true to the field. See the document here

 ....
 resource: YourResource,
 options: {
   properties: {
      YourField : {isRequired: true}
   }
 }
 ....
