# Rollup
|
|
|
|
|
|
|
|
|
|
This library presents itself as a CommonJS library, so some configuration is
|
|
|
|
|
required. The examples at <https://rollupjs.org> can be followed pretty much in
|
2017-09-24 23:40:09 +00:00
|
|
|
verbatim. 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` and `rollup-plugin-commonjs` plugins are used:
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
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()
|
|
|
|
|
],
|
|
|
|
|
/* ... */
|
|
|
|
|
};
|
|
|
|
|
```
|
|
|
|
|
|

|
|
|
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:
|
|
|
|
|
|
|
|
|
|
```diff
|
|
|
|
|
-importScripts('dist/xlsx.full.min.js');
|
|
|
|
|
+import XLSX from 'xlsx';
|
|
|
|
|
```
|
