Extends HTML Webpack Plugin to add support for partials or templates.
Relies on html-webpack-plugin 4+ (currently at beta)
yarn add html-webpack-partials-plugin -D
or
npm add html-webpack-partials-plugin --save-dev
Require the plugin in your webpack config:
const HtmlWebpackPartialsPlugin = require('html-webpack-partials-plugin');
Add the plugin to your webpack config as follows:
plugins: [
new HtmlWebpackPlugin(),
new HtmlWebpackPartialsPlugin({
path: './path/to/partials/body.html'
})
]
Set up your partial:
<div>Hello World!</div>
| Name | Type | Default | Description |
|---|---|---|---|
| path | String | none | Partial location |
| inject | Boolean | true | Conditionally inject your partial |
| location | String | "body" | HTML tag name where the the partial gets added |
| priority | String | "low" | "high" or "low" - determines if the partial gets added from the start of the location or end |
| template_filename | String | "index.html" | The filename of the HTML Webpack Plugin template that the partial should be attributed to. By default this is index.html, the HTML Webpack Plugin default output. Additionally, passing * will apply the partial to all templates in the compilation. This doesn't currently work in a regex format, thus something like *.html will NOT work and the only functionality * will provide is to match all templates. |
| options | Object | {} | Local variables to the given partial |
The settings can either be passed in as a single object or an array of objects.
Don't bother creating a custom template just to add a React root element, simply add it as a partial!
Using an example of webpack.config.js with Babel installed:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const HtmlWebpackPartialsPlugin = require('../../');
module.exports = {
entry: {
main: path.join(__dirname, './main.js')
},
output: {
path: path.join(__dirname, './dist'),
filename: '[name].js'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: [
'@babel/preset-env',
'@babel/preset-react'
]
}
}
}
]
},
plugins: [
new HtmlWebpackPlugin(),
new HtmlWebpackPartialsPlugin({
path: path.join(__dirname, './partials/body.html')
})
]
};
Add a mounting point for your application at partials/body.html:
<div id="root"></div>
💪Now your app has something to render to!
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Webpack App</title>
</head>
<body>
<div id="root"></div><script type="text/javascript" src="main.js"></script></body>
</html>
The recommended installation of Google Optimize alongside Google Analytics includes installing the snippet immediately after the <meta charset tag from the initial server-returned HTML. Loading this clientside using something like React Helmet, unless using server side rendering, won't give us the benefits of giving an optimal loading experience when running A/B tests. To fix this, we can inject this snippet using a partial without having to create a custom HTML template file or trying to sloppily manage it in our app.
Using a basic example of webpack.config.js:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const HtmlWebpackPartialsPlugin = require('../../');
module.exports = {
entry: {
main: path.join(__dirname, './main.js') // Not shown in thix example
},
output: {
path: path.join(__dirname, './dist'),
filename: '[name].js'
},
plugins: [
new HtmlWebpackPlugin(),
new HtmlWebpackPartialsPlugin([
{
path: path.join(__dirname, './partials/analytics.html'),
priority: 'high',
location: 'head'
}
])
]
};
Using example code from the installation guide, set up partials/analytics.html:
<!-- Page-hiding snippet (recommended) -->
<style>.async-hide { opacity: 0 !important} </style>
<script>(function(a,s,y,n,c,h,i,d,e){s.className+=' '+y;h.start=1*new Date;
h.end=i=function(){s.className=s.className.replace(RegExp(' ?'+y),'')};
(a[n]=a[n]||[]).hide=h;setTimeout(function(){i();h.end=null},c);h.timeout=c;
})(window,document.documentElement,'async-hide','dataLayer',4000,
{'GTM-XXXXXX':true});</script>
<!-- Modified Analytics tracking code with Optimize plugin -->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-XXXXXXXX-X', 'auto');
ga('require', 'GTM-XXXXXX');
ga('send', 'pageview');
</script>
🙆 now you're analytics code can be easily maintained and installed in the right spot!
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"><!-- Page-hiding snippet (recommended) -->
<style>.async-hide { opacity: 0 !important} </style>
<script>(function(a,s,y,n,c,h,i,d,e){s.className+=' '+y;h.start=1*new Date;
h.end=i=function(){s.className=s.className.replace(RegExp(' ?'+y),'')};
(a[n]=a[n]||[]).hide=h;setTimeout(function(){i();h.end=null},c);h.timeout=c;
})(window,document.documentElement,'async-hide','dataLayer',4000,
{'GTM-XXXXXX':true});</script>
<!-- Modified Analytics tracking code with Optimize plugin -->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){

Given the location and priority passed into the configuration, the plugin determines where to inject. The location is simply the name of the tag to use, where the priority is how high or how low in the tag we inject. For almost all situations, a high priority will inject immediately after the opening tag and low will inject immediately before the closing tag.
The one exception to this, if the passed in tagname is head with a high priority, the plugin will inject immediately after <meta charset="utf-8">.
The order is determined simply by the order in which the partial is included in the configuration.
