CameronJS HTML Webpack Plugin

Adds support for simple HTML layouts and partials

Install

yarn add cameronjs-html-webpack-plugin

Add to your webpack.config.js:

const CameronJSHtmlWebpackPlugin = require("cameronjs-html-webpack-plugin");

module.exports = {
  // ...
  output: {
    //...
    path: path.resolve(__dirname, "public")
  },
  plugins: [
    new CameronJSHtmlWebpackPlugin({
      source: "./src/html",
      layouts: "layouts"
    })
  ],
  // ...
};

Options

source is relative to webpack.config.js and is where your HTML templates live.

layouts is relative to source and is where your layout files live.

Generated HTML pages will be emitted to the output.path set in the config file.

Usage

Layouts

Layouts surround your HTML content and provide a "frame". The standard declarations for your pages probably don't change much between pages so they're perfect for a layout:

<!-- src/html/layouts/application.html -->

<!DOCTYPE html>
<html>
<head>
  <title>@@title</title>
</head>
<body>
  @@content
</body>
</html>

You use @@content to denote where the real content of your page will be inserted into the layout and any other variables you want to be replaced by prefixing them with @@.

To denote that a page should use a layout add a @@layout declaration at the top of the page to say which one to use, with an optional list of those variables you want to substitute:

<!-- src/html/index.html -->

@@layout("application", { "title": "My Site" })
<h1>Hello, world</h1>

The final rendered HTML will be emitted to wherever output.path is set in webpack.config.js:

<!-- public/index.html -->

<!DOCTYPE html>
<html>
<head>
  <title>My Site</title>
</head>
<body>
  <h1>Hello, world</h1>
</body>
</html>

Layouts are great for parts of your site that don't change between pages. This way you write them once and share them everywhere.

Partials

Partials are smaller snippets of HTML that you want to share between pages. A navigation bar is a good example:

<!-- src/html/_nav.html -->

<nav>
  <ul>
    <li><a href="/">Home</a></li>
    <li><a href="/account">Account</a></li>
  </ul>
</nav>

Note that the filename must begin with a _underscore. This helps you distinguish between full pages and partials when you're looking at a list of files in your editor. In the page where you want to use the partial you'll provide a @@partial declaration (this time without the leading underscore):

<!-- src/html/index.html -->

@@partial("nav.html")
<h1>Hello, world</h1>

And the final built HTML page would look like:

<!-- public/index.html -->

<nav>
  <ul>
    <li><a href="/">Home</a></li>
    <li><a href="/account">Account</a></li>
  </ul>
</nav>

<h1>Hello, world</h1>

(Note the @@layout declaration was not present so this page won't be wrapped in a layout.)

You can pass variable substitutions to partials if you want the parent page to make some data available to the child partial.

<!-- src/html/parts/_title.html -->

<header>
  <h1>@@pageTitle</h1>
  <h2>Welcome @@user.name</h2>
</nav>

<!-- src/html/index.html -->

@@partial("parts/title.html", { "pageTitle": "Welcome!", "user": { "name": "Rob" } })

<main>
  <p>Lorem ipsum dolar sit amet...</p>
</main>

Note that in the above example the partial lived in a different directory than the main file.

Notes

You can combine partials and layouts and reference one from the other. Perhaps you have multiple layouts but they should all share the same <head> tag content. Include the @@partial in both layouts and you're good to go:

<!-- src/html/layouts/site.html -->

<!DOCTYPE html>
<html>
@@partial("head.html")
<body>
  <h1>My Site</h1>
  @@content
</body>
</html>

<!-- src/html/layouts/admin.html -->

<!DOCTYPE html>
<html>
@@partial("admin.html")
<body>
  <h1>Admins Only</h1>
  @@content
</body>
</html>

Thanks

This package was made possible by digging through the source on file-include-webpack-plugin and this plugin borrowed some code from it!
