I’m new to Vaadin and Vue.js, so I can just guess some technical details. Does Spreadsheet work with Vue.js without any complex programming and “integration tricks”?
Vaadin Spreadsheet component works with Vaadin 7 & 8. Its base logic is based on Apache POI library in server side with tightly coupled logic to Vaadin 7 or 8 client side, so it is not possible to use it with JavaScript frameworks like Vue.js and React without complex programming and “integration tricks”. If you need pure JavaScript Spreadsheet, for example Handsontable could be one alternative.
