We have already figured out the packaging for handsontable in systemjs/jspm. I’m already using it with reactjs in a project.
As an example, to make this project work - https://github.com/sandys/systems-handsontable - you need to add this package.json .
request for handsontable and handsontable-rulejs to be added to the jspm registry here https://github.com/jspm/registry/ . you dont need to publish it to npm. the jspm registry will pull from github
