metalsmith-uglify

This is an UglifyJS plugin for Metalsmith and is a successor to the original plugin written by Keith Smith.

Usage

Install the package:

npm install metalsmith-uglify

Add the plugin to your Metalsmith build chain:

var metalsmith = require('metalsmith');
var uglify = require('metalsmith-uglify');

metalsmith(__dirname)
    .source('./src')
    .destination('./public')
    .use(uglify());
    .build(function (err) {
        if (err) {
            throw err;
        }

        console.log('Build complete');
    });

Options

The plugin function accepts a configuration object as the first argument.

{boolean} options.es - Set to use uglify-es package instead of uglify-js. It will set also set options.uglify.ecma = 6 by default.
{object} options.concat - Set to concatenate to a single bundle file. UglifyJS does not provide any ordering guarantees.
- {string} options.concat.file - Name of the bundle file. Default is scripts.min.js.
- {string} options.concat.root - Set to limit the plugin to a specific source directory. This option overrides options.root.
{function} options.filter - Function to filter the list of JavaScript files. By default .min.js files are excluded.
{string} options.root - Set to limit the plugin to a specific source directory.
{boolean} options.removeOriginal - Set to exclude the original (unminified) file from the output directory.
{boolean} options.sameName - Set to keep minified name as is without adding .min. This option overrides options.removeOriginal and is ignored if options.concat is set.
{object} options.uglify - UglifyJS configuration (see UglifyJS docs). Default is { sourceMap: { includeSources: true } }.
{boolean} options.windows - Set this if you are using the plugin on Windows.

Upgrading from version 1.x

Version 2 is a rewrite of the plugin with significant breaking changes to the options object.

Please refer to the upgrade document for more information.

Debug Logging

Set the DEBUG variable to see what the plugin is doing.

If you are troubleshooting the plugin itself then the following should be enough:

DEBUG=metalsmith-uglify:info:* node build.js

If you think the problem is actually related to something UglifyJS does then you can get more detail:

DEBUG=metalsmith-uglify:* node build.js
