rollup-plugin-bundle-html

This plugin inject the bundle js file as well as external js files to html template. This plugin extends from rollup-plugin-fill-html to provide more flexibility for injecting files.

Installation

yarn add --dev rollup-plugin-bundle-html

npm install -D rollup-plugin-bundle-html

Usage

import html from 'rollup-plugin-bundle-html';

export default {
  input: 'src/main.js',
  output: {
    file: 'dist/foo/bundle.js',
  },
  plugins: [
    html({
        template: 'src/template.html',
        // or html code: '<html><head></head><body></body></html>'
        dest: "dist/foo",
        filename: 'index.html',
        inject: 'head',
        externals: [
            { type: 'js', file: "file1.js", pos: 'before' },
            { type: 'js', file: "file2.js", pos: 'before' }
        ]
    })
  ]
};

<!-- src/template.html -->
<html>
  <head>
  </head>
  <body>
  </body>
</html>

<!-- dist/foo/index.html -->
<html>
  <head>
    <script type="text/javascript" src="../../file1.js"></script>
    <script type="text/javascript" src="../../file2.js"></script>
    <script type="text/javascript" src="bundle.js"></script>
  </head>
  <body>
  </body>
</html>

Hash

You can set string '[hash]' for output file in rollup.config.js, and your bundle and source map (if you turned on sourcemap option) will have the string '[hash]' be replaced by its hash.

export default {
  input: 'src/main.js',
  output: {
    file: 'dist/foo/bundle-[hash].js',
    // Turn on sourcemap
    sourcemap: true
  },
  plugins: [
    ...
  ]
};

You will find both bundle and map files are hashed and placed in your dist/foo folder: bundle-76bf4fb5dbbd62f0fa3708aa3d8a9350.js, bundle-84e0f899735b1e320e625c9a5c7c49a7.js.map

onlinePath

You can set 'onlinePath' as anything like //www.sohu.com/ if you want to put the files on CDN after building.

{
  output: {
    file: 'dist/foo/main.js',
  },
  // ...
  plugins: [
    html({
        dest: "dist/foo",
        // ...
        onlinePath: '//www.sohu.com/dist/foo'
    })
  ]
}

and you will get something like: <script src="//www.sohu.com/dist/foo/main.js"></script>.

Options

You can pass an option to the html() just like above, and there are some options:

template: (required) either path or code string of the template file, template should be a html file.
filename: optional if 'template' is a path: the name of the result html file, if omitted, will use name in template as file name.
externals: (optional) a list of files which will be insert into the resule html. The file should be a valid url.

- externals.pos: position where the file is inserted.
- externals.timestamp: append timestamp as query string to file path.
inject: (optional) indicate where to insert files， it can be 'head' or 'body'. For default, the css files will be inserted into <head> and the js files will be inserted into <body>.
defaultmode: (optional) specify a value to use in the script type attribute. If no mode is specified, the type attribute is omitted. Externals can optionally override this per file.
dest: (optional) the folder in which js file is searched and be injected to html file.
