Angular

Hello. The question arises point-blank, the subject itself: it is necessary to develop a leaflet editor
. If possible, indicate the advantages of your choice in your answer.
And I would like to know from you how best to transfer data to the server and process it?
For example, the canvas in the editor is fully dynamic (html). In what form is it better to transfer information to the server in order to exclude left xss. In this case, it will be necessary to assemble it back into html on the server side and convert it to PDF or image. Tell me who knows what
Many thanks guys for the subsequent answers!

On the server side, clean up the html with whatever tool your stack has available.
