<h1>HTML Webpack Plugin</h1>
<p>Plugin that simplifies creation of HTML files to serve your bundles</p>
</div>
<h2 align="center">Install</h2>
```bash
npm i --save-dev html-webpack-plugin
```
```bash
yarn add --dev html-webpack-plugin
```
This is a [webpack](http://webpack.js.org/) plugin that simplifies creation of HTML files to serve your `webpack` bundles. This is especially useful for `webpack` bundles that include a hash in the filename which changes every compilation. You can either let the plugin generate an HTML file for you, supply
your own template using `lodash` templates or use your own loader.

Thanks for supporting the ongoing improvements to the html-webpack-plugin!
<h2 align="center">Zero Config</h2>
The `html-webpack-plugin` works without configuration.
It's a great addition to the [⚙️ webpack-config-plugins](https://github.com/namics/webpack-config-plugins/blob/master/README.md#zero-config-webpack-dev-server-example).
<h2 align="center">Plugins</h2>
The `html-webpack-plugin` provides [hooks](https://github.com/jantimon/html-webpack-plugin#events) to extend it to your needs. There are already some really powerful plugins which can be integrated with zero configuration
* [webpack-subresource-integrity](https://www.npmjs.com/package/webpack-subresource-integrity) for enhanced asset security
* [appcache-webpack-plugin](https://github.com/lettertwo/appcache-webpack-plugin) for iOS and Android offline usage
* [favicons-webpack-plugin](https://github.com/jantimon/favicons-webpack-plugin) which generates favicons and icons for iOS, Android and desktop browsers
* [html-webpack-harddisk-plugin](https://github.com/jantimon/html-webpack-harddisk-plugin) can be used to always write to disk the html file, useful when webpack-dev-server / HMR are being used
* [html-webpack-inline-source-plugin](https://github.com/DustinJackson/html-webpack-inline-source-plugin) to inline your assets in the resulting HTML file
* [html-webpack-inline-svg-plugin](https://github.com/thegc/html-webpack-inline-svg-plugin) to inline SVGs in the resulting HTML file.
* [html-webpack-exclude-assets-plugin](https://github.com/jamesjieye/html-webpack-exclude-assets-plugin) for excluding assets using regular expressions
* [html-webpack-include-assets-plugin](https://github.com/jharris4/html-webpack-include-assets-plugin) for including lists of js or css file paths (such as those copied by the copy-webpack-plugin).
* [script-ext-html-webpack-plugin](https://github.com/numical/script-ext-html-webpack-plugin) to add `async`, `defer` or `module` attributes to your `<script>` elements, or even inline them
* [style-ext-html-webpack-plugin](https://github.com/numical/style-ext-html-webpack-plugin) to convert your `<link>`s to external stylesheets into `<style>` elements containing internal CSS
* [html-webpack-injector](https://github.com/thearchitgarg/html-webpack-injector) to inject chunks in `head` or `body` (different locations ) of same html document.
* [resource-hints-webpack-plugin](https://github.com/jantimon/resource-hints-webpack-plugin) to add resource hints for faster initial page loads using `<link rel='preload'>` and `<link rel='prefetch'>`
* [preload-webpack-plugin](https://github.com/GoogleChrome/preload-webpack-plugin) for automatically wiring up asynchronous (and other types) of JavaScript chunks using `<link rel='preload'>` helping with lazy-loading
* [link-media-html-webpack-plugin](https://github.com/yaycmyk/link-media-html-webpack-plugin) allows for injected stylesheet `<link />` tags to have their media attribute set automatically; useful for providing specific desktop/mobile/print etc. stylesheets that the browser will conditionally download
* [inline-chunk-manifest-html-webpack-plugin](https://github.com/jouni-kantola/inline-chunk-manifest-html-webpack-plugin) for inlining webpack's chunk manifest. Default extracts manifest and inlines in `<head>`
* [html-webpack-inline-style-plugin](https://github.com/djaax/html-webpack-inline-style-plugin) for inlining styles to HTML elements using [juice](https://github.com/Automattic/juice). Useful for email generation automatisation.
* [html-webpack-exclude-empty-assets-plugin](https://github.com/KnisterPeter/html-webpack-exclude-empty-assets-plugin) removes empty assets from being added to the html. This fixes some problems with extract-text-plugin with webpack 4.
* [webpack-concat-plugin](https://github.com/hxlniada/webpack-concat-plugin) for concat and uglify files that needn't to be webpack bundles(for legacy files) and inject to html-webpack-plugin.
* [html-webpack-link-type-plugin](https://github.com/steadyapp/html-webpack-link-type-plugin) adds a configurable mimetype to resources injected as links (such as adding type="text/css" to external stylesheets) for compatibility with "strict mode".
* [csp-html-webpack-plugin](https://github.com/slackhq/csp-html-webpack-plugin) to add [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy) meta tags to the HTML output
* [webpack-nomodule-plugin](https://github.com/swimmadude66/webpack-nomodule-plugin) allows you to add a `nomodule` attribute to specific injected scripts, which prevents the scripts from being loaded by newer browsers. Good for limiting loads of polyfills.
<h2 align="center">Usage</h2>
The plugin will generate an HTML5 file for you that includes all your `webpack`
bundles in the body using `script` tags. Just add the plugin to your `webpack`
config as follows:
**webpack.config.js**
```js
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
entry: 'index.js',
output: {
path: __dirname + '/dist',
filename: 'index_bundle.js'
},
plugins: [
new HtmlWebpackPlugin()
]
}
```
This will generate a file `dist/index.html` containing the following
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Webpack App</title>
</head>
<body>
<script src="index_bundle.js"></script>
</body>
</html>
```
If you have multiple `webpack` entry points, they will all be included with `script` tags in the generated HTML.
If you have any CSS assets in webpack's output (for example, CSS extracted with the [mini-css-extract-plugin](https://github.com/webpack-contrib/mini-css-extract-plugin))
then these will be included with `<link>` tags in the HTML head.
If you have plugins that make use of it, `html-webpack-plugin` should be ordered first before any of the integrated plugins.
<h2 align="center">Options</h2>
You can pass a hash of configuration options to `html-webpack-plugin`.
Allowed values are as follows
|Name|Type|Default|Description|
|:--:|:--:|:-----:|:----------|
|**`title`**|`{String}`|`Webpack App`|The title to use for the generated HTML document|
|**`filename`**|`{String}`|`'index.html'`|The file to write the HTML to. Defaults to `index.html`. You can specify a subdirectory here too (eg: `assets/admin.html`)|
|**`template`**|`{String}`|``|`webpack` relative or absolute path to the template. By default it will use `src/index.ejs` if it exists. Please see the [docs](https://github.com/jantimon/html-webpack-plugin/blob/master/docs/template-option.md) for details|
|**`templateParameters`**|`{Boolean\|Object\|Function}`|``| Allows to overwrite the parameters used in the template - see [example](https://github.com/jantimon/html-webpack-plugin/tree/master/examples/template-parameters) |
|**`inject`**|`{Boolean\|String}`|`true`|`true \|\| 'head' \|\| 'body' \|\| false` Inject all assets into the given `template` or `templateContent`. When passing `true` or `'body'` all javascript resources will be placed at the bottom of the body element. `'head'` will place the scripts in the head element - see the [inject:false example](https://github.com/jantimon/html-webpack-plugin/tree/master/examples/custom-insertion-position)|
|**`scriptLoading`**|`{'blocking'\|'defer'}`|`'blocking'`| Modern browsers support non blocking javascript loading (`'defer'`) to improve the page startup performance. |
|**`favicon`**|`{String}`|``|Adds the given favicon path to the output HTML|
|**`meta`**|`{Object}`|`{}`|Allows to inject `meta`-tags. E.g. `meta: {viewport: 'width=device-width, initial-scale=1, shrink-to-fit=no'}`|
|**`base`**|`{Object\|String\|false}`|`false`|Inject a [`base`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base) tag. E.g. `base: "https://example.com/path/page.html`|
|**`minify`**|`{Boolean\|Object}`|`true` if `mode` is `'production'`, otherwise `false`|Controls if and in what ways the output should be minified. See [minification](#minification) below for more details.|
|**`hash`**|`{Boolean}`|`false`|If `true` then append a unique `webpack` compilation hash to all included scripts and CSS files. This is useful for cache busting|
|**`cache`**|`{Boolean}`|`true`|Emit the file only if it was changed|
|**`showErrors`**|`{Boolean}`|`true`|Errors details will be written into the HTML page|
|**`chunks`**|`{?}`|`?`|Allows you to add only some chunks (e.g only the unit-test chunk)|
|**[`chunksSortMode`](#plugins)**|`{String\|Function}`|`auto`|Allows to control how chunks should be sorted before they are included to the HTML. Allowed values are `'none' \| 'auto' \| 'dependency' \| 'manual' \| {Function}`|
|**`excludeChunks`**|`{Array.<string>}`|``|Allows you to skip some chunks (e.g don't add the unit-test chunk)|
|**`xhtml`**|`{Boolean}`|`false`|If `true` render the `link` tags as self-closing (XHTML compliant)|
Here's an example webpack config illustrating how to use these options
**webpack.config.js**
```js
{
entry: 'index.js',
output: {
path: __dirname + '/dist',
filename: 'index_bundle.js'
},
plugins: [
new HtmlWebpackPlugin({
title: 'My App',
filename: 'assets/admin.html'
})
]
}
```
### Generating Multiple HTML Files
To generate more than one HTML file, declare the plugin more than
once in your plugins array
**webpack.config.js**
```js
{
entry: 'index.js',
output: {
path: __dirname + '/dist',
filename: 'index_bundle.js'
},
plugins: [
new HtmlWebpackPlugin(), // Generates default index.html
new HtmlWebpackPlugin({ // Also generate a test.html
filename: 'test.html',
template: 'src/assets/test.html'
})
]
}
```
### Writing Your Own Templates
If the default generated HTML doesn't meet your needs you can supply
your own template. The easiest way is to use the `template` option and pass a custom HTML file.
The html-webpack-plugin will automatically inject all necessary CSS, JS, manifest
and favicon files into the markup.
Details of other template loaders are [documented here](https://github.com/jantimon/html-webpack-plugin/blob/master/docs/template-option.md).
```js
plugins: [
new HtmlWebpackPlugin({
title: 'Custom template',
// Load a custom template (lodash by default)
template: 'index.html'
})
]
```
**index.html**
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title><%= htmlWebpackPlugin.options.title %></title>
</head>
<body>
</body>
</html>
```
If you already have a template loader, you can use it to parse the template.
Please note that this will also happen if you specify the html-loader and use `.html` file as template.
**webpack.config.js**
```js
module: {
loaders: [
{ test: /\.hbs$/, loader: "handlebars-loader" }
]
},
plugins: [
new HtmlWebpackPlugin({
title: 'Custom template using Handlebars',
template: 'index.hbs'
})
]
```
You can use the `lodash` syntax out of the box. If the `inject` feature doesn't fit your needs and you want full control over the asset placement use the [default template](https://github.com/jaketrent/html-webpack-template/blob/86f285d5c790a6c15263f5cc50fd666d51f974fd/index.html) of the [html-webpack-template project](https://github.com/jaketrent/html-webpack-template) as a starting point for writing your own.
The following variables are available in the template:
- `htmlWebpackPlugin`: data specific to this plugin
- `htmlWebpackPlugin.files`: a massaged representation of the
`assetsByChunkName` attribute of webpack's [stats](https://github.com/webpack/docs/wiki/node.js-api#stats)
object. It contains a mapping from entry point name to the bundle filename, eg:
```json
"htmlWebpackPlugin": {
"files": {
"css": [ "main.css" ],
"js": [ "assets/head_bundle.js", "assets/main_bundle.js"],
"chunks": {
"head": {
"entry": "assets/head_bundle.js",
"css": [ "main.css" ]
},
"main": {
"entry": "assets/main_bundle.js",
"css": []
},
}
}
}
```
If you've set a publicPath in your webpack config this will be reflected
correctly in this assets hash.
- `htmlWebpackPlugin.options`: the options hash that was passed to
the plugin. In addition to the options actually used by this plugin,
you can use this hash to pass arbitrary data through to your template.
- `webpack`: the webpack [stats](https://github.com/webpack/docs/wiki/node.js-api#stats)
object. Note that this is the stats object as it was at the time the HTML template
was emitted and as such may not have the full set of stats that are available
after the webpack run is complete.
- `webpackConfig`: the webpack configuration that was used for this compilation. This
can be used, for example, to get the `publicPath` (`webpackConfig.output.publicPath`).
- `compilation`: the webpack [compilation object](https://webpack.js.org/api/compilation-object/).
This can be used, for example, to get the contents of processed assets and inline them
directly in the page, through `compilation.assets[...].source()`
(see [the inline template example](examples/inline/template.pug)).
### Filtering Chunks
To include only certain chunks you can limit the chunks being used
**webpack.config.js**
```js
plugins: [
new HtmlWebpackPlugin({
chunks: ['app']
})
]
```
It is also possible to exclude certain chunks by setting the `excludeChunks` option
**webpack.config.js**
```js
plugins: [
new HtmlWebpackPlugin({
excludeChunks: [ 'dev-helper' ]
})
]
```
### Minification
If the `minify` option is set to `true` (the default when webpack's `mode` is `'production'`),
the generated HTML will be minified using [html-minifier-terser](https://github.com/DanielRuf/html-minifier-terser)
and the following options:
```js
{
collapseWhitespace: true,
removeComments: true,
removeRedundantAttributes: true,
removeScriptTypeAttributes: true,
removeStyleLinkTypeAttributes: true,
useShortDoctype: true
}
```
To use custom [html-minifier options](https://github.com/DanielRuf/html-minifier-terser#options-quick-reference)
pass an object to `minify` instead. This object will not be merged with the defaults above.
To disable minification during production mode set the `minify` option to `false`.
### Meta Tags
If the `meta` option is set the html-webpack-plugin will inject meta tags.
For the default template the html-webpack-plugin will already provide a default for the `viewport` meta tag.
Please take a look at this well maintained list of almost all [possible meta tags](https://github.com/joshbuchea/HEAD#meta).
#### name/content meta tags
Most meta tags are configured by setting a `name` and a `content` attribute.
To add those use a key/value pair:
**webpack.config.js**
```js
plugins: [
new HtmlWebpackPlugin({
'meta': {
'viewport': 'width=device-width, initial-scale=1, shrink-to-fit=no',
// Will generate: <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
'theme-color': '#4285f4'
// Will generate: <meta name="theme-color" content="#4285f4">
}
})
]
```
#### Simulate http response headers
The **http-equiv** attribute is essentially used to simulate a HTTP response header.
This format is supported using an object notation which allows you to add any attribute:
**webpack.config.js**
```js
plugins: [
new HtmlWebpackPlugin({
'meta': {
'Content-Security-Policy': { 'http-equiv': 'Content-Security-Policy', 'content': 'default-src https:' },
// Will generate: <meta http-equiv="Content-Security-Policy" content="default-src https:">
// Which equals to the following http header: `Content-Security-Policy: default-src https:`
'set-cookie': { 'http-equiv': 'set-cookie', content: 'name=value; expires=date; path=url' },
// Will generate: <meta http-equiv="set-cookie" content="value; expires=date; path=url">
// Which equals to the following http header: `set-cookie: value; expires=date; path=url`
}
})
]
```
### Base Tag
When the `base` option is used,
html-webpack-plugin will inject a [base tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/base).
By default, a base tag will not be injected.
The following two are identical and will both insert `<base href="http://example.com/some/page.html">`:
```js
new HtmlWebpackPlugin({
'base': 'http://example.com/some/page.html'
})
```
```js
new HtmlWebpackPlugin({
'base': { 'href': 'http://example.com/some/page.html' }
})
```
The `target` can be specified with the corresponding key:
```js
new HtmlWebpackPlugin({
'base': {
'href': 'http://example.com/some/page.html',
'target': '_blank'
}
})
```
which will inject the element `<base href="http://example.com/some/page.html" target="_blank">`.
### Long Term Caching
For long term caching add `contenthash/templatehash` to the filename.
**Example:**
```js
plugins: [
new HtmlWebpackPlugin({
filename: 'index.[contenthash].html'
})
]
```
`contenthash/templatehash` is the hash of the content of the output file.
Optionally, You can configure like `[<hashType>:contenthash:<digestType>:<length>]`
* `hashType` - one of `sha1`, `md5`, `sha256`, `sha512` or any other node.js supported hash type
* `digestType` - one of `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
* `maxlength` - maximum length of the generated hash in chars
**Defaults:** `[md5:contenthash:hex:9999]`
### Events
To allow other [plugins](https://github.com/webpack/docs/wiki/plugins) to alter the HTML this plugin executes
[tapable](https://github.com/webpack/tapable/tree/master) hooks.
The [lib/hooks.js](https://github.com/jantimon/html-webpack-plugin/blob/master/lib/hooks.js) contains all information
about which values are passed.
[![Concept flow uml](https://raw.githubusercontent.com/jantimon/html-webpack-plugin/master/flow.png)](https://github.com/jantimon/html-webpack-plugin/blob/master/flow.puml)
#### `beforeAssetTagGeneration` hook
```
AsyncSeriesWaterfallHook<{
assets: {
publicPath: string,
js: Array<{string}>,
css: Array<{string}>,
favicon?: string | undefined,
manifest?: string | undefined
},
outputName: string,
plugin: HtmlWebpackPlugin
}>
```
#### `alterAssetTags` hook
```
AsyncSeriesWaterfallHook<{
assetTags: {
scripts: Array<HtmlTagObject>,
styles: Array<HtmlTagObject>,
meta: Array<HtmlTagObject>,
},
outputName: string,
plugin: HtmlWebpackPlugin
}>
```
#### `alterAssetTagGroups` hook
```
AsyncSeriesWaterfallHook<{
headTags: Array<HtmlTagObject | HtmlTagObject>,
bodyTags: Array<HtmlTagObject | HtmlTagObject>,
outputName: string,
plugin: HtmlWebpackPlugin
}>
```
#### `afterTemplateExecution` hook
```
AsyncSeriesWaterfallHook<{
html: string,
headTags: Array<HtmlTagObject | HtmlTagObject>,
bodyTags: Array<HtmlTagObject | HtmlTagObject>,
outputName: string,
plugin: HtmlWebpackPlugin,
}>
```
#### `beforeEmit` hook
```
AsyncSeriesWaterfallHook<{
html: string,
outputName: string,
plugin: HtmlWebpackPlugin,
}>
```
#### `afterEmit` hook
```
AsyncSeriesWaterfallHook<{
outputName: string,
plugin: HtmlWebpackPlugin
}>
```
Example implementation: [webpack-subresource-integrity](https://www.npmjs.com/package/webpack-subresource-integrity)
**plugin.js**
```js
// If your plugin is direct dependent to the html webpack plugin:
const HtmlWebpackPlugin = require('html-webpack-plugin');
// If your plugin is using html-webpack-plugin as an optional dependency
// you can use https://github.com/tallesl/node-safe-require instead:
const HtmlWebpackPlugin = require('safe-require')('html-webpack-plugin');
class MyPlugin {
apply (compiler) {
compiler.hooks.compilation.tap('MyPlugin', (compilation) => {
console.log('The compiler is starting a new compilation...')
// Static Plugin interface |compilation |HOOK NAME | register listener
HtmlWebpackPlugin.getHooks(compilation).beforeEmit.tapAsync(
'MyPlugin', // <-- Set a meaningful name here for stacktraces
(data, cb) => {
// Manipulate the content
data.html += 'The Magic Footer'
// Tell webpack to move on
cb(null, data)
}
)
})
}
}
module.exports = MyPlugin
```
**webpack.config.js**
```js
plugins: [
new MyPlugin({ options: '' })
]
```
Note that the callback must be passed the HtmlWebpackPluginData in order to pass this onto any other plugins listening on the same `beforeEmit` event
