memmap is unmaintained

Flagging this issue as "good first issue" & "help wanted", since it is an easy one.

Move the logic inside the promise callback of dragStart() into a new method.

        Neo.main.DomAccess.getBoundingClientRect({
            id: me.getDragElementRoot().id
        }).then(rect => {
            offsetX = data.clientX - rect.left;
            offsetY = data.clientY - rect.top;

      

I have a idea. Auto create a typescript project by run es4x init with --typescript or -t 。It's not manual copy file by sample.
And “mvnDependencies ” added to the package.json by default. Because a lot of people don't know about it。
If you agree, I can modify this code. ^_^
