+# `dependency-tree-esm`
+
+Returns an unordered array of local paths to dependencies of a Node ES module JavaScript file.
+
+* See also: [`dependency-tree`](https://github.com/11ty/eleventy-dependency-tree) for the CommonJS version.
+
+This is used by Eleventy to find dependencies of a JavaScript file to watch for changes to re-run Eleventy’s build.
+
+## Installation
+
+```
+npm install --save-dev @11ty/dependency-tree-esm
+```
+
+## Features
+
+* Ignores bare specifiers (e.g. `import "my-package"`)
+* Ignores Node’s built-ins (e.g. `import "path"`)
+* Handles circular dependencies
+* Returns an empty set if the file does not exist.
+
+## Usage
+
+```js
+// my-file.js
+
+// if my-local-dependency.js has dependencies, it will include those too
+import "./my-local-dependency.js";
+
+
+// ignored, is a built-in
+import path from "path";
+```
+
+```js
+const { find } = require("@11ty/dependency-tree-esm");
+
+find("./my-file.js");
+// returns ["./my-local-dependency.js"]
+```

+# Dependency Graph Changelog
+
+## 0.11.0 (March 5, 2021)
+
+- Add `entryNodes` method that returns the nodes that nothing depends on - thanks [amcdnl](https://github.com/amcdnl)!
+
+## 0.10.0 (January 9, 2021)
+
+- Add `directDependenciesOf` and `directDependantsOf` methods for retrieving direct dependency information. (Fixes #40)
+- Add aliases `dependentsOf` and `directDependentsOf`.
+
+## 0.9.0 (February 10, 2020)
+
+- Rewrite the topological sort DFS to be more efficient (and work!) on large graphs.
+  - No longer uses recursion to avoid stack overflows with large/deep graphs
+  - No longer is accidentally `O(N^2)` (thanks [willtennien](https://github.com/willtennien) for pointing this out!)
+
+## 0.8.1 (December 3, 2019)
+
+- Ensure all nodes are included in overallOrder when cycles are allowed. (Fixes #33)
+
+## 0.8.0 (December 11, 2018)
+
+- Add a `DepGraphCycleError` with cyclePath property - thanks [jhugman](https://github.com/jhugman)!
+
+## 0.7.2 (August 30, 2018)
+
+- Make constructor parameter optional in Typescript definition. (Fixes #26)
+
+## 0.7.1 (June 5, 2018)
+
+- Fix Typescript definition to include the new constructor arguments added in `0.7.0` - thanks [tbranyen](https://github.com/tbranyen)!
+
+## 0.7.0 (January 17, 2018)
+
+- Allow circular dependencies by passing in `{circular: true}` into the constructor - thanks [tbranyen](https://github.com/tbranyen)!
+
+## 0.6.0 (October 22, 2017)
+
+- Add a `size` method that will return the number of nodes in the graph.

+
+- Add missing parameter in TypeScript definition. (Fixes #19)
+
+## 0.5.1 (October 7, 2017)
+
+- Now exposes Typescript type definition - thanks [vangorra](https://github.com/vangorra)!
+
+## 0.5.0 (April 26, 2016)
+
+- Add optional data parameter for the addNode method. (Fixes #12)
+- Add methods getNodeData and setNodeData to manipulate the data associated with a node name. (Fixes #12)
+- Change the hasNode method to be able to cope with falsy node data. (Fixes #12)
+
+## 0.4.1 (Sept 3, 2015)
+
+- Check all nodes for potential cycles when calculating overall order. (Fixes #8)
+
+## 0.4.0 (Aug 1, 2015)
+
+- Better error messages
+  - When a cycle is detected, the error message will now include the cycle in it. E.g `Dependency Cycle Found: a -> b -> c -> a` (Fixes #7)
+  - When calling `addDependency` if one of the nodes does not exist, the error will say which one it was (instead of saying that "one" of the two nodes did not exist and making you manually determine which one)
+- Calling `overallOrder` on an empty graph will no longer throw an error about a dependency cycle. It will return an empty array.
+
+## 0.3.0 (July 24, 2015)
+
+- Fix issue where if you call `addNode` twice with the same name, it would clear all edges for that node. Now it will do nothing if a node with the specified name already exists. (Fixes #3)
+
+## 0.2.1 (July 3, 2015)
+
+- Fixed removeNode leaving references in outgoingEdges and reference to non-existent var edges - thanks [juhoha](https://github.com/juhoha)! (Fixes #2)
+
+## 0.2.0 (May 1, 2015)
+
+- Removed dependency on Underscore - thanks [myndzi](https://github.com/myndzi)! (Fixes #1)
+
+## 0.1.0 (May 18, 2013)
+
+- Initial Release - extracted out of asset-smasher

+# Dependency Graph
+
+Simple dependency graph
+
+## Overview
+
+This is a simple dependency graph useful for determining the order to do a list of things that depend on certain items being done before they are.
+
+To use, `npm install dependency-graph` and then `require('dependency-graph').DepGraph`
+
+## API
+
+### DepGraph
+
+Nodes in the graph are just simple strings with optional data associated with them.
+
+ - `addNode(name, data)` - add a node in the graph with optional data. If `data` is not given, `name` will be used as data
+ - `removeNode(name)` - remove a node from the graph
+ - `hasNode(name)` - check if a node exists in the graph
+ - `size()` - return the number of nodes in the graph
+ - `getNodeData(name)` - get the data associated with a node (will throw an `Error` if the node does not exist)
+ - `setNodeData(name, data)` - set the data for an existing node (will throw an `Error` if the node does not exist)
+ - `addDependency(from, to)` - add a dependency between two nodes (will throw an `Error` if one of the nodes does not exist)
+ - `removeDependency(from, to)` - remove a dependency between two nodes
+ - `clone()` - return a clone of the graph. Any data attached to the nodes will only be *shallow-copied*
+ - `dependenciesOf(name, leavesOnly)` - get an array containing the nodes that the specified node depends on (transitively). If `leavesOnly` is true, only nodes that do not depend on any other nodes will be returned in the array.
+ - `dependantsOf(name, leavesOnly)` (aliased as `dependentsOf`) - get an array containing the nodes that depend on the specified node (transitively). If `leavesOnly` is true, only nodes that do not have any dependants will be returned in the array.
+ - `directDependenciesOf(name)` - get an array containing the direct dependencies of the specified node
+ - `directDependantsOf(name)` (aliased as `directDependentsOf`) - get an array containing the nodes that directly depend on the specified node
+ - `overallOrder(leavesOnly)` - construct the overall processing order for the dependency graph. If `leavesOnly` is true, only nodes that do not depend on any other nodes will be returned.
+ - `entryNodes()` - array of nodes that have no dependants (i.e. nothing depends on them).
+
+Dependency Cycles are detected when running `dependenciesOf`, `dependantsOf`, and `overallOrder` and if one is found, a `DepGraphCycleError` will be thrown that includes what the cycle was in the message as well as the `cyclePath` property: e.g. `Dependency Cycle Found: a -> b -> c -> a`. If you wish to silence this error, pass `circular: true` when instantiating `DepGraph` (more below).
+
+## Examples
+
+    var DepGraph = require('dependency-graph').DepGraph;
+
+    var graph = new DepGraph();
+    graph.addNode('a');
+    graph.addNode('b');
+    graph.addNode('c');
+
+    graph.size() // 3
+
+    graph.addDependency('a', 'b');
+    graph.addDependency('b', 'c');
+
+    graph.dependenciesOf('a'); // ['c', 'b']
+    graph.dependenciesOf('b'); // ['c']
+    graph.dependantsOf('c'); // ['a', 'b']
+
+    graph.overallOrder(); // ['c', 'b', 'a']
+    graph.overallOrder(true); // ['c']
+    graph.entryNodes(); // ['a']
+
+    graph.addNode('d', 'data');
+
+    graph.getNodeData('d'); // 'data'
+
+    graph.setNodeData('d', 'newData');
+
+    graph.getNodeData('d'); // 'newData'
+
+    var circularGraph = new DepGraph({ circular: true });
+
+    circularGraph.addNode('a');
+    circularGraph.addNode('b');
+    circularGraph.addNode('c');
+    circularGraph.addNode('d');
+
+    circularGraph.addDependency('a', 'b');
+    circularGraph.addDependency('b', 'c'); // b depends on c
+    circularGraph.addDependency('c', 'a'); // c depends on a, which depends on b
+    circularGraph.addDependency('d', 'a');
+
+    circularGraph.dependenciesOf('b'); // ['a', 'c']
+    circularGraph.overallOrder(); // ['c', 'b', 'a', 'd']

+# `dependency-tree`
+
+Returns an unordered array of local paths to dependencies of a CommonJS node JavaScript file (everything it or any of its dependencies `require`s).
+
+* See also: [`dependency-tree-esm`](https://github.com/11ty/eleventy-dependency-tree-esm) for ES Modules.
+
+Reduced feature (faster) alternative to the [`dependency-tree` package](https://www.npmjs.com/package/dependency-tree). This is used by Eleventy to find dependencies of a JavaScript file to watch for changes to re-run Eleventy’s build.
+
+## Big Huge Caveat
+
+⚠ A big caveat to this plugin is that it will require the file in order to build a dependency tree. So if your module has side effects and you don’t want it to execute—do not use this!
+
+## Installation
+
+```
+npm install --save-dev @11ty/dependency-tree
+```
+
+## Features
+
+* Ignores `node_modules`
+* Or, use `nodeModuleNames` to control whether or not `node_modules` package names are included (added in v2.0.1)
+* Ignores Node’s built-ins (e.g. `path`)
+* Handles circular dependencies (Node does this too)
+
+## Usage
+
+```js
+// my-file.js
+
+// if my-local-dependency.js has dependencies, it will include those too
+const test = require("./my-local-dependency.js");
+
+// ignored, is a built-in
+const path = require("path");
+```
+
+```js
+const DependencyTree = require("@11ty/dependency-tree");
+
+DependencyTree("./my-file.js");
+// returns ["./my-local-dependency.js"]
+```
+
+### `allowNotFound`
+
+```js
+const DependencyTree = require("@11ty/dependency-tree");
+
+DependencyTree("./this-does-not-exist.js"); // throws an error
+
+DependencyTree("./this-does-not-exist.js", { allowNotFound: true });
+// returns []
+```
+
+### `nodeModuleNames`
+
+(Added in v2.0.1) Controls whether or not node package names are included in the list of dependencies.
+
+* `nodeModuleNames: "include"`: included alongside the local JS files.
+* `nodeModuleNames: "exclude"` (default): node module package names are excluded.
+* `nodeModuleNames: "only"`: only node module package names are returned.
+
+```js
+// my-file.js:
+
+require("./my-local-dependency.js");
+require("@11ty/eleventy");
+```
+
+```js
+const DependencyTree = require("@11ty/dependency-tree");
+
+DependencyTree("./my-file.js");
+// returns ["./my-local-dependency.js"]
+
+DependencyTree("./my-file.js", { nodeModuleNames: "exclude" });
+// returns ["./my-local-dependency.js"]
+
+DependencyTree("./my-file.js", { nodeModuleNames: "include" });
+// returns ["./my-local-dependency.js", "@11ty/eleventy"]
+
+DependencyTree("./my-file.js", { nodeModuleNames: "only" });
+// returns ["@11ty/eleventy"]
+```
+
+#### (Deprecated) `nodeModuleNamesOnly`
+
+(Added in v2.0.0) Changed to use `nodeModuleNames` option instead. Backwards compatibility is maintained automatically.
+
+* `nodeModuleNamesOnly: false` is mapped to `nodeModuleNames: "exclude"`
+* `nodeModuleNamesOnly: true` is mapped to `nodeModuleNames: "only"`
+
+If both `nodeModuleNamesOnly` and `nodeModuleNames` are included in options, `nodeModuleNames` takes precedence.

+# eleventy-dev-server 🕚⚡️🎈🐀
+
+A minimal, modern, generic, hot-reloading local web server to help web developers.
+
+## ➡ [Documentation](https://www.11ty.dev/docs/watch-serve/#eleventy-dev-server)
+
+- Please star [Eleventy on GitHub](https://github.com/11ty/eleventy/)!
+- Follow us on Twitter [@eleven_ty](https://twitter.com/eleven_ty)
+- Support [11ty on Open Collective](https://opencollective.com/11ty)

+
+[![npm Version](https://img.shields.io/npm/v/@11ty/eleventy-dev-server.svg?style=for-the-badge)](https://www.npmjs.com/package/@11ty/eleventy-dev-server)
+
+## Installation
+
+This is bundled with `@11ty/eleventy` (and you do not need to install it separately) in Eleventy v2.0.
+
+## CLI
+
+Eleventy Dev Server now also includes a CLI. The CLI is for **standalone** (non-Eleventy) use only: separate installation is unnecessary if you’re using this server with `@11ty/eleventy`.
+
+```sh
+npm install -g @11ty/eleventy-dev-server
+
+# Alternatively, install locally into your project
+npm install @11ty/eleventy-dev-server
+```
+
+This package requires Node 18 or newer.
+
+### CLI Usage
+
+```sh
+# Serve the current directory
+npx @11ty/eleventy-dev-server
+
+# Serve a different subdirectory (also aliased as --input)
+npx @11ty/eleventy-dev-server --dir=_site
+
+# Disable the `domdiff` feature
+npx @11ty/eleventy-dev-server --domdiff=false
+
+# Full command list in the Help
+npx @11ty/eleventy-dev-server --help
+```
+
+## Tests
+
+```
+npm run test
+```
+
+- We use the [ava JavaScript test runner](https://github.com/avajs/ava) ([Assertions documentation](https://github.com/avajs/ava/blob/master/docs/03-assertions.md))
+
+## Changelog
+
+* `v2.0.0` bumps Node.js minimum to 18.

+# eleventy-plugin-bundle
+
+Little bundles of code, little bundles of joy.
+
+Create minimal per-page or app-level bundles of CSS, JavaScript, or HTML to be included in your Eleventy project.
+
+Makes it easy to implement Critical CSS, in-use-only CSS/JS bundles, SVG icon libraries, or secondary HTML content to load via XHR.
+
+## Why?
+
+This project is a minimum-viable-bundler and asset pipeline in Eleventy. It does not perform any transpilation or code manipulation (by default). The code you put in is the code you get out (with configurable `transforms` if you’d like to modify the code).
+
+For more larger, more complex use cases you may want to use a more full featured bundler like Vite, Parcel, Webpack, rollup, esbuild, or others.
+
+But do note that a full-featured bundler has a significant build performance cost, so take care to weigh the cost of using that style of bundler against whether or not this plugin has sufficient functionality for your use case—especially as the platform matures and we see diminishing returns on code transpilation (ES modules everywhere).
+
+## Installation
+
+No installation necessary. Starting with Eleventy `v3.0.0-alpha.10` and newer, this plugin is now bundled with Eleventy.
+
+## Usage
+
+By default, Bundle Plugin v2.0 does not include any default bundles. You must add these yourself via `eleventyConfig.addBundle`. One notable exception happens when using the WebC Eleventy Plugin, which adds `css`, `js`, and `html` bundles for you.
+
+To create a bundle type, use `eleventyConfig.addBundle` in your Eleventy configuration file (default `.eleventy.js`):
+
+```js
+// .eleventy.js
+export default function(eleventyConfig) {
+	eleventyConfig.addBundle("css");
+};
+```
+
+This does two things:
+
+1. Creates a new `css` shortcode for adding arbitrary code to this bundle
+2. Adds `"css"` as an eligible type argument to the `getBundle` and `getBundleFileUrl` shortcodes.
+
+### Full options list
+
+```js
+export default function(eleventyConfig) {
+	eleventyConfig.addBundle("css", {
+		// (Optional) Folder (relative to output directory) files will write to
+		toFileDirectory: "bundle",
+
+		// (Optional) File extension used for bundle file output, defaults to bundle name
+		outputFileExtension: "css",
+
+		// (Optional) Name of shortcode for use in templates, defaults to bundle name
+		shortcodeName: "css",
+		// shortcodeName: false, // disable this feature.
+
+		// (Optional) Modify bundle content
+		transforms: [],
+
+		// (Optional) If two identical code blocks exist in non-default buckets, they’ll be hoisted to the first bucket in common.
+		hoist: true,
+
+		// (Optional) In 11ty.js templates, having a named export of `bundle` will populate your bundles.
+		bundleExportKey: "bundle",
+		// bundleExportKey: false, // disable this feature.
+	});
+};
+```
+
+Read more about [`hoist` and duplicate bundle hoisting](https://github.com/11ty/eleventy-plugin-bundle/issues/5).
+
+### Universal Shortcodes
+
+The following Universal Shortcodes (available in `njk`, `liquid`, `hbs`, `11ty.js`, and `webc`) are provided by this plugin:
+
+* `getBundle` to retrieve bundled code as a string.
+* `getBundleFileUrl` to create a bundle file on disk and retrieve the URL to that file.
+
+Here’s a [real-world commit showing this in use on the `eleventy-base-blog` project](https://github.com/11ty/eleventy-base-blog/commit/c9595d8f42752fa72c66991c71f281ea960840c9?diff=split).
+
+### Example: Add bundle code in a Markdown file in Eleventy
+
+```md
+# My Blog Post
+
+This is some content, I am writing markup.
+
+{% css %}
+em { font-style: italic; }
+{% endcss %}
+
+## More Markdown
+
+{% css %}
+strong { font-weight: bold; }
+{% endcss %}
+```
+
+Renders to:
+
+```html
+<h1>My Blog Post</h1>
+
+<p>This is some content, I am writing markup.</p>
+
+<h2>More Markdown</h2>
+```
+
+Note that the bundled code is excluded!
+
+_There are a few [more examples below](#examples)!_
+
+### Render bundle code
+
+```html
+<!-- Use this *anywhere*: a layout file, content template, etc -->
+<style>{% getBundle "css" %}</style>
+
+<!--
+You can add more code to the bundle after calling
+getBundle and it will be included.
+-->
+{% css %}* { color: orange; }{% endcss %}
+```
+
+### Write a bundle to a file
+
+Writes the bundle content to a content-hashed file location in your output directory and returns the URL to the file for use like this:
+
+```html
+<link rel="stylesheet" href="{% getBundleFileUrl "css" %}">
+```
+
+Note that writing bundles to files will likely be slower for empty-cache first time visitors but better cached in the browser for repeat-views (and across multiple pages, too).
+
+### Asset bucketing
+
+```html
+<!-- This goes into a `defer` bucket (the bucket can be any string value) -->
+{% css "defer" %}em { font-style: italic; }{% endcss %}
+```
+
+```html
+<!-- Pass the arbitrary `defer` bucket name as an additional argument -->
+<style>{% getBundle "css", "defer" %}</style>
+<link rel="stylesheet" href="{% getBundleFileUrl 'css', 'defer' %}">
+```
+
+A `default` bucket is implied:
+
+```html
+<!-- These two statements are the same -->
+{% css %}em { font-style: italic; }{% endcss %}
+{% css "default" %}em { font-style: italic; }{% endcss %}
+
+<!-- These two are the same too -->
+<style>{% getBundle "css" %}</style>
+<style>{% getBundle "css", "default" %}</style>
+```
+
+### Examples
+
+#### Critical CSS
+
+```js
+// .eleventy.js
+export default function(eleventyConfig) {
+	eleventyConfig.addBundle("css");
+};
+```
+
+Use asset bucketing to divide CSS between the `default` bucket and a `defer` bucket, loaded asynchronously.
+
+_(Note that some HTML boilerplate has been omitted from the sample below)_
+
+```html
+<!-- … -->
+<head>
+	<!-- Inlined critical styles -->
+	<style>{% getBundle "css" %}</style>
+
+	<!-- Deferred non-critical styles -->
+	<link rel="stylesheet" href="{% getBundleFileUrl 'css', 'defer' %}" media="print" onload="this.media='all'">
+	<noscript>
+		<link rel="stylesheet" href="{% getBundleFileUrl 'css', 'defer' %}">
+	</noscript>
+</head>
+<body>
+	<!-- This goes into a `default` bucket -->
+	{% css %}/* Inline in the head, great with @font-face! */{% endcss %}
+	<!-- This goes into a `defer` bucket (the bucket can be any string value) -->
+	{% css "defer" %}/* Load me later */{% endcss %}
+</body>
+<!-- … -->
+```
+
+**Related**:
+
+* Check out the [demo of Critical CSS using Eleventy Edge](https://demo-eleventy-edge.netlify.app/critical-css/) for a repeat view optimization without JavaScript.
+* You may want to improve the above code with [`fetchpriority`](https://www.smashingmagazine.com/2022/04/boost-resource-loading-new-priority-hint-fetchpriority/) when [browser support improves](https://caniuse.com/mdn-html_elements_link_fetchpriority).
+
+#### SVG Icon Library
+
+Here an `svg` is bundle is created.
+
+```js
+// .eleventy.js
+export default function(eleventyConfig) {
+	eleventyConfig.addBundle("svg");
+};
+```
+
+```html
+<svg width="0" height="0" aria-hidden="true" style="position: absolute;">
+	<defs>{% getBundle "svg" %}</defs>
+</svg>
+
+<!-- And anywhere on your page you can add icons to the set -->
+{% svg %}
+<g id="icon-close"><path d="…" /></g>
+{% endsvg %}
+
+And now you can use `icon-close` in as many SVG instances as you’d like (without repeating the heftier SVG content).
+
+<svg><use xlink:href="#icon-close"></use></svg>
+<svg><use xlink:href="#icon-close"></use></svg>
+<svg><use xlink:href="#icon-close"></use></svg>
+<svg><use xlink:href="#icon-close"></use></svg>
+```
+
+#### React Helmet-style `<head>` additions
+
+```js
+// .eleventy.js
+export default function(eleventyConfig) {
+	eleventyConfig.addBundle("html");
+};
+```
+
+This might exist in an Eleventy layout file:
+
+```html
+<head>
+	{% getBundle "html", "head" %}
+</head>
+```
+
+And then in your content you might want to page-specific `preconnect`:
+
+```html
+{% html "head" %}
+<link href="https://v1.opengraph.11ty.dev" rel="preconnect" crossorigin>
+{% endhtml %}
+```
+
+#### Bundle Sass with the Render Plugin
+
+You can render template syntax inside of the `{% css %}` shortcode too, if you’d like to do more advanced things using Eleventy template types.
+
+This example assumes you have added the [Render plugin](https://www.11ty.dev/docs/plugins/render/) and the [`scss` custom template type](https://www.11ty.dev/docs/languages/custom/) to your Eleventy configuration file.
+
+```html
+{% css %}
+  {% renderTemplate "scss" %}
+  h1 { .test { color: red; } }
+  {% endrenderTemplate %}
+{% endcss %}
+```
+
+Now the compiled Sass is available in your default bundle and will show up in `getBundle` and `getBundleFileUrl`.
+
+#### Use with [WebC](https://www.11ty.dev/docs/languages/webc/)
+
+Starting with `@11ty/eleventy-plugin-webc@0.9.0` (track at [issue #48](https://github.com/11ty/eleventy-plugin-webc/issues/48)) this plugin is used by default in the Eleventy WebC plugin. Specifically, [WebC Bundler Mode](https://www.11ty.dev/docs/languages/webc/#css-and-js-(bundler-mode)) now uses the bundle plugin under the hood.
+
+To add CSS to a bundle in WebC, you would use a `<style>` element in a WebC page or component:
+
+```html
+<style>/* This is bundled. */</style>
+<style webc:keep>/* Do not bundle me—leave as is */</style>
+```
+
+To add JS to a page bundle in WebC, you would use a `<script>` element in a WebC page or component:
+
+```html
+<script>/* This is bundled. */</script>
+<script webc:keep>/* Do not bundle me—leave as is */</script>
+```
+
+* Existing calls via WebC helpers `getCss` or `getJs` (e.g. `<style @raw="getCss(page.url)">`) have been wired up to `getBundle` (for `"css"` and `"js"` respectively) automatically.
+	* For consistency, you may prefer using the bundle plugin method names everywhere: `<style @raw="getBundle('css')">` and `<script @raw="getBundle('js')">` both work fine.
+* Outside of WebC, the Universal Filters `webcGetCss` and `webcGetJs` were removed in Eleventy `v3.0.0-alpha.10` in favor of the `getBundle` Universal Shortcode (`{% getBundle "css" %}` and `{% getBundle "js" %}` respectively).
+
+#### Modify the bundle output
+
+You can wire up your own async-friendly callbacks to transform the bundle output too. Here’s a quick example of [`postcss` integration](https://github.com/postcss/postcss#js-api).
+
+```js
+const postcss = require("postcss");
+const postcssNested = require("postcss-nested");
+
+export default function(eleventyConfig) {
+	eleventyConfig.addBundle("css", {
+		transforms: [
+			async function(content) {
+				// this.type returns the bundle name.
+				// Same as Eleventy transforms, this.page is available here.
+				let result = await postcss([postcssNested]).process(content, { from: this.page.inputPath, to: null });
+				return result.css;
+			}
+		]
+	});
+};
+```
+
+## Advanced
+
+### Limitations
+
+Bundles do not support nesting or recursion (yet?). If this will be useful to you, please file an issue!
+
+<!--
+Version Two:
+
+* Think about Eleventy transform order, scenarios where this transform needs to run first.
+* JavaScript API independent of eleventy
+* Clean up the _site/bundle folder on exit?
+* Example ideas:
+	* App bundle and page bundle
+* can we make this work for syntax highlighting? or just defer to WebC for this?
+
+{% css %}
+<style>
+em { font-style: italic; }
+</style>
+{% endcss %}
+* a way to declare dependencies? or just defer to buckets here
+* What if we want to add code duplicates? Adding `alert(1);` `alert(1);` to alert twice?
+* sourcemaps (maybe via magic-string module or https://www.npmjs.com/package/concat-with-sourcemaps)

+
+- The use of sexualized language or imagery and unwelcome sexual attention or advances
+- Trolling, insulting/derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or electronic address, without explicit permission
+- Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, chat messages, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at eleventy@zachleat.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]
