But I have no idea what to actually do - where is this "...d.ts" - file - should I create this? Where should I actually put this? There is nothing helpful for someone completely new in the matter. Can you point me what exactly should I do to avoid this problem?
"ERROR in node_modules/ng2-alfresco-core/src/utils/file-utils.ts(19,13): error TS2304: Cannot find name 'WebKitFileEntry'."
I am sorry for causing trouble. I just had to take another way so I managed to avoid using the "ng2-alfresco-core" - not quite a solution I expected but nonetheless - it works the same as I wanted using the newer module.
