+# Browserify
+
+The library is compatible with browserify and should just work out of the box.
+
+This demo uses the `require` form to expose the whole library, enabling client
+code to just `require('xlsx')`.  The included demo and Makefile do just that.

+# SystemJS Demos
+
+SystemJS supports both browser and nodejs deployments.  It does not recognize
+browser environments and automatically suppress node core modules, but with some
+configuration magic SystemJS can load the library.
+
+## Browser
+
+SystemJS fails by default because the library does not export anything in the
+web browser.  This is easily addressed in the config:
+
+```js
+SystemJS.config({
+	meta: {
+		'xlsx': {
+			exports: 'XLSX' // <-- tell SystemJS to expose the XLSX variable
+		}
+	},
+	map: {
+		'xlsx': 'xlsx.full.min.js', // <-- make sure xlsx.full.min.js is in same dir
+		'fs': '',     // <--|
+		'crypto': '', // <--| suppress native node modules
+		'stream': ''  // <--|
+	}
+});
+SystemJS.import('main.js')
+```
+
+In your main JS script, just use require:
+
+```js
+var XLSX = require('xlsx');
+var w = XLSX.read('abc,def\nghi,jkl', {type:'binary'});
+var j = XLSX.utils.sheet_to_json(w.Sheets[w.SheetNames[0]], {header:1});
+console.log(j);
+```
+
+The file functions `readFile` and `writeFile` are not available in the browser.
+
+## Node
+
+The node core modules should be mapped to their `@node` equivalents:
+
+```js
+var SystemJS = require('systemjs');
+SystemJS.config({
+	map: {
+		'xlsx': 'node_modules/xlsx/xlsx.js',
+		'fs': '@node/fs',
+		'crypto': '@node/crypto',
+		'stream': '@node/stream'
+	}
+});
+```
+
+And use is pretty straightforward:
+
+```js
+SystemJS.import('xlsx').then(function(XLSX) {
+	/* XLSX is available here */
+	var w = XLSX.readFile('test.xlsx');
+	var j = XLSX.utils.sheet_to_json(w.Sheets[w.SheetNames[0]], {header:1});
+	console.log(j);
+});
+```
+

demos/systemjs/main.js

+var XLSX = require('xlsx');
+console.log(XLSX);
+var w = XLSX.read('abc,def\nghi,jkl', {type:'binary'});
+var j = XLSX.utils.sheet_to_json(w.Sheets[w.SheetNames[0]], {header:1});
+console.log(j);

demos/webpack/README.md

+# Webpack
+
+This library is built with some dynamic logic to determine if it is invoked in a
+script tag or in nodejs.  Webpack does not understand those feature tests, so by
+default it will do some strange things.
+
+## Suppressing the Node shims
+
+The library properly guards against accidental leakage of node features in the
+browser but webpack disregards those.  The config should explicitly suppress:
+
+```js
+	node: {
+		fs: false,
+		process: false,
+		Buffer: false
+	}
+```
+
+## Exporting the XLSX variable
+
+This library will not assign to module.exports if it is run in the browser.  To
+convince webpack, set `output` in the webpack config:
+
+```js
+	output: {
+		libraryTarget: 'var',
+		library: 'XLSX'
+	}
+```
