Rollup

This library has a proper ESM build that is enabled by default:

import { read, utils } from 'xlsx';

This sample demonstrates a bundle for browser as well as for node.

This demo uses the import form to expose the whole library, enabling client code to access the library with import XLSX from 'xlsx'. The JS code from the root demo was moved to a separate app.js script.

Required Plugins

The rollup-plugin-node-resolve plugin is used:

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

For the browser deployments, the output format is 'iife'. For node, the output format is 'cjs'.

Worker Scripts

Rollup can also bundle worker scripts! Instead of using importScripts, the worker script should import the module:

-importScripts('dist/xlsx.full.min.js');
+import * as XLSX from 'xlsx'; // or do named imports
