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.
yarn add --dev rollup-plugin-bundle-html
or
npm install -D rollup-plugin-bundle-html
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>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
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>.
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.file: file path.
- externals.type: the type of file. can be 'js' or 'css'.
- 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
typeattribute. If no mode is specified, thetypeattribute 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.
- absolute: (optional) indicates is paths of injected files should starts with "/".
- ignore: (optional) specify a regex that will prevent all matching files from being injected.
- onlinePath: (optional) add an onlinePath prefix to the file while bundle file would be pushed into CDN instead of a local file.
