This is because it parses markup into a tree structure, then modifies it (removing anything that was specified for removal, ignoring anything that was specified to be ignored, etc.), then it creates a markup out of that tree and returns it. - -Input markup (e.g. `<p id="">foo`) - -↓ - -Internal representation of markup in a form of tree (e.g. `{ tag: "p", attr: "id", children: ["foo"] }`) - -↓ - -Transformation of internal representation (e.g. removal of `id` attribute) - -↓ - -Output of resulting markup (e.g. `<p>foo</p>`) - -HTMLMinifier can't know that original markup was only half of the tree; it does its best to try to parse it as a full tree and it loses information about tree being malformed or partial in the beginning. As a result, it can't create a partial/malformed tree at the time of the output. - -## Installation Instructions - -From NPM for use as a command line app: - -```shell -npm install html-minifier -g -``` - -From NPM for programmatic use: - -```shell -npm install html-minifier -``` - -From Git: - -```shell -git clone git://github.com/kangax/html-minifier.git -cd html-minifier -npm link . -``` - -## Usage - -For command line usage please see `html-minifier --help` - -### Node.js - -```js -var minify = require('html-minifier').minify; -var result = minify('<p title="blah" id="moo">foo</p>', { - removeAttributeQuotes: true -}); -result; // '<p title=blah id=moo>foo</p>' -``` - -## Running benchmarks - -Benchmarks for minified HTML: - -```shell -node benchmark.js -``` diff --git a/node_modules/html-minifier/cli.js b/node_modules/html-minifier/cli.js deleted file mode 100755 index 84db90b8c..000000000 --- a/node_modules/html-minifier/cli.js +++ /dev/null @@ -1,310 +0,0 @@ -#!/usr/bin/env node -/** - * html-minifier CLI tool - * - * The MIT License (MIT) - * - * Copyright (c) 2014-2016 Zoltan Frombach - * - * Permission is hereby granted, free of charge, to any person obtaining a copy of - * this software and associated documentation files (the "Software"), to deal in - * the Software without restriction, including without limitation the rights to - * use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of - * the Software, and to permit persons to whom the Software is furnished to do so, - * subject to the following conditions: - * - * The above copyright notice and this permission notice shall be included in all - * copies or substantial portions of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS - * FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
