Rollup: missing export of Buffer

NOTE: if you are using stencil with rollup-plugin-node-polyfills, pass an exclude option

I got the bellow error when I use xlsx module with stenciljs with MAC machine. Module is working fine in windows. Rollup: Missing Export: ./node_modules/xlsx/dist/cpexcel.js:1:9

‘Buffer’ is not exported by node-resolve:empty.js, imported by

./node_modules/xlsx/dist/cpexcel.js

L1: /*! cpexcel.js © 2013-present SheetJS – http://sheetjs.com */

L2: /*jshint -W100 */

Thanks in advance

Thanks @MarkChrisLevy , the issue can be reproduced using that plugin and your solution works. Unfortunately that option is not in the plugin docs 😦

The raw rollup demo works with the polyfills plugin, probably because it also uses rollup-plugin-node-resolve (now @rollup/plugin-node-resolve)

https://github.com/SheetJS/sheetjs/tree/master/demos/rollup#required-plugins mentions some override:

import resolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
export default {
	/* ... */
	plugins: [
		resolve({
			module: false, // <-- this library is not an ES6 module
			browser: true, // <-- suppress node-specific features
		}),
		commonjs()
	],
	/* ... */
};

Does that help?
