This webpack plugin is run when the jigsawDone event.

Install with npm:

npm i @thelevicole/webpack-minify-jigsaw-output --save-dev

Include the plugin in your webpack.mix.js file as follows:

const mix = require('laravel-mix');
const MinifyJigsawOutput = require('@thelevicole/webpack-minify-jigsaw-output');
require('laravel-mix-jigsaw');

...

And then add the plugin to the webpack config:

...

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            verbose: true
        })
    ]
});

The full webpack.mix.js should look something like...

const mix = require('laravel-mix');
const MinifyJigsawOutput = require('webpack-minify-jigsaw-output');
require('laravel-mix-jigsaw');

mix.disableSuccessNotifications();
mix.setPublicPath('source/assets/build');

mix.jigsaw()
    .js('source/_assets/js/main.js', 'js')
    .sass('source/_assets/sass/main.scss', 'css')
    .options({
        processCssUrls: false,
    })
    .version();

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            verbose: true
        })
    ]
});

The below options can be passed to the plugin.

This is an object of rules will be passed as is to HTMLMinifier. If empty, the default value is used: { collapseWhitespace: true }.

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            rules: {
                caseSensitive: true,
                collapseWhitespace: true,
                minifyJS: true
            }
        })
    ]
});

The above example will:

• Treat attributes in case sensitive manner (useful for custom HTML tags)
• Collapse white space that contributes to text nodes in a document tree
• Minify JavaScript in script elements and event attributes (uses UglifyJS)

Set a specific build environment for dynamically guessing the output directories. If empty, the env parameter parsed to node is used.

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            env: 'production'
        })
    ]
});

The above example will only minify the build output in the build_production directory.

Accepts a string or array of environment names for which minification should run. If empty, the default value is used: '*'

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            allowedEnvs: ['production', 'staging']
        })
    ]
});

The above example will only run the minification process when the build environment is either production or staging, local will not be minified.

This option increases the amount of information you are given during the minification process. If empty, the default value is used: false

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            verbose: true
        })
    ]
});

The above example will print a list of minified files as and when they are processed, for example:

• [MinifyJigsawOutput] Minifing /Users/example/my-site/build_production/index.html
• [MinifyJigsawOutput] Minifing /Users/example/my-site/build_production/about/index.html

The regular expression used before to check if a file should be minified. If empty, the default value is used: /\.html$/

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            test: /about\/.*\.html$/
        })
    ]
});

The above example will only process .html files found in the about directory, for example:

• /Users/example/my-site/build_production/about/index.html
• /Users/example/my-site/build_production/about/the-team/index.html

Please note that this full path is tested against the regex pattern, so the above example would minify all html files if a directory outside of the project includes "about". E.g.

• /Users/about/my-site/build_production/index.html
• /Users/example/project-about/build_production/index.html

If for some reason you need to set the file encoding used to read the input source, use this option. The allowed values are determined by node.js, a good thread about supported encodings can be found here: https://stackoverflow.com/a/14551669/3804924 If empty, the default value is used: 'utf8'

mix.webpackConfig({
    plugins: [
        new MinifyJigsawOutput({
            encoding: 'latin1'
        })
    ]
});
