Sina HTML Webpack Plugin

Plugin that simplifies creation of HTML files to serve your bundles

在社区版本的基础上增加的功能:


import url 注入打包出来的html

template功能和html-loader并存

Install

``bash
yarn add sina-html-webpack-plugin
`

import url需安装 marauder-umd-loader

`bash
yarn add marauder-umd-loader
`

引用方式如下:

onlineUrl: 必须

inject: body(默认),head

type: js(默认),css

(tip: 如果引用的 js 为 mjs.sinaimg.cn/umd 下的 sina umd 组件，marauder-umd-loader 将对组件做版本限制，只引用一个版本，若引用多个版本将引入失败)

`js
import "marauder-umd-loader?inject=body&type=js&onlineUrl=https://mjs.sinaimg.cn/wap/online/public/wapLogin/wapLogin_main.js!@mfelibs/base-tools-SUDA";
`

This is a webpack 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.

The html-webpack-plugin provides hooks to extend it to your needs. There are already some really powerful plugins which can be integrated with zero configuration

* webpack-subresource-integrity for enhanced asset security
* appcache-webpack-plugin for iOS and Android offline usage
* favicons-webpack-plugin which generates favicons and icons for iOS, Android and desktop browsers
* 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 to inline your assets in the resulting HTML file
* html-webpack-inline-svg-plugin to inline SVGs in the resulting HTML file.
* html-webpack-exclude-assets-plugin for excluding assets using regular expressions
* 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 to add async, defer or module attributes to your


`

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 ExtractTextPlugin)
then these will be included with 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.

Options

You can pass a hash of configuration options to html-webpack-plugin.
Allowed values are as follows

| Name | Type | Default | Description |
| :------------------------------: | :------------------: | :---------------------------------------------------------------------------------------------------------------------------------------------------------------: | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| title | {String} | |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 require path to the template. Please see the docs for details |
| 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 |
| favicon | {String} | |Adds the given favicon path to the output HTML |
| minify | {Boolean\|Object} | true | Pass html-minifier's options as object to minify the output |
| 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 | {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 | {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'
})
]
}
`

$3

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'
})
]
}
`

$3

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.

`js
plugins: [
new HtmlWebpackPlugin({
title: "Custom template",
// Load a custom template (lodash by default see the FAQ for details)
template: "index.html"
})
];
`

index.html

`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 specifiy the html-loader and use .html file as template.

webpack.config.js

`js
module: {
loaders: [
{ test: /\.hbs$/, loader: "handlebars" }
]
},
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 of the html-webpack-template project 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
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
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.
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).

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"]
})
];
`

$3

To allow other plugins to alter the HTML this plugin executes the following events:

#### Sync

* html-webpack-plugin-alter-chunks

#### Async

* html-webpack-plugin-before-html-generation
* html-webpack-plugin-before-html-processing
* html-webpack-plugin-alter-asset-tags
* html-webpack-plugin-after-html-processing
* html-webpack-plugin-after-emit

Example implementation: html-webpack-harddisk-plugin

plugin.js

`js
function MyPlugin(options) {
// Configure your plugin with options...
}

MyPlugin.prototype.apply = function(compiler) {
compiler.plugin("compilation", compilation => {
console.log("The compiler is starting a new compilation...");

compilation.plugin(
"html-webpack-plugin-before-html-processing",
(data, cb) => {
data.html += "The Magic Footer";

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 html-webpack-plugin-before-html-processing event
