網頁前端自動化工具 – Grunt
Grunt 網站截圖
今天為各位介紹的是一個前端工程師所使用的自動化工具「Grunt」，為何我們要使用這個工具呢？其實使用這個工具的原因有很多，因為他的擴充模組（Plugin）也很多，不過今天馬老師從自動最小化（Minify）的角度來介紹這個工具該如何使用。
一般來說前端網頁開發不外乎HTML、CSS、Javascript這三種語法，而在開發完成之後，為了要節省流量，我們可能會把這三個檔案壓縮後再上傳到網站伺服器上，何謂壓縮請參考下圖：
 未經壓縮的HTML檔 |
 經過壓縮的HTML檔 |
 未經壓縮的CSS檔 |
 經過壓縮的CSS檔 |
 未經壓縮的JS檔 |
 經過壓縮的JS檔 |
從上面的檔案可以觀察出在開發時我們為了閱讀的便利，常常會利用註解、空白…等來輔助，但真正發佈出去這些東西卻不是必要的，甚至在開發的時候我們為了方面會把CSS或JS拆成好幾個檔案，但發佈之後卻希望可以合併，但如果需要人工來做這件事，可想而知會有多麻煩，這個時候Grunt就會發揮效用了，設定好之後只要一個指令，他就可以幫我們做好這些動作，接下來就來看看該如何使用吧。
首先Grunt是一個基於node.js下的應用程序，所以必須先安裝node.js，安裝的部分並不難，從官網下載後直接執行安裝即可。
Node.js 官方網站 截圖
接下來可以參考Grunt網站中Getting Started的單元，或是跟著以下（以Windows為案例）的方式進行Grunt的安裝。
- 打開「命令提示字元」。
- 輸入「npm install -g grunt-cli」。
- 接下來就可以準備網頁專案資料夾了，如下圖所示，我的網頁專案資料夾簡單分成兩個：
- src：所有開發檔案
- public：發佈至網路上的檔案
準備專案資料夾
- 這樣準備的目的應該很清楚，就是希望在src資料夾內以自己最習慣、最方便閱讀的方式來開發，而開發完畢之後可以把壓縮的檔案轉至public資料夾，上傳到伺服器上。
有關於網頁內容開發的部分，本篇文章就省略，所以可以看到上面圖檔中我已經準備好了HTML、CSS、JS各一個，直接進入利用Grunt開始做自動最小化的部分。
- 使用Grunt時，必須在網站根目錄建立兩個檔案：
- package.json：Grunt的專案設定檔，其中可以包含專案名稱、作者、版本，所需要使用的Plugin…等，可以參考下面我的檔案。
- Grunt.js：Grunt的執行腳本，以本案例來說就是要去哪個資料夾，壓縮哪些檔案後存放在哪邊，需在本檔案中指定。
{ "name": "gruntTest", "version": "0.1.0", "author": "Stanley Ma", "devDependencies": { "grunt": "~0.4.5", "grunt-contrib-htmlmin": "~0.4.0", "grunt-contrib-cssmin": "~0.13.0", "grunt-contrib-uglify": "~0.9.2" } }以上面的package.json檔案來說，定義了專案名稱、作者、版本以及所需要使用的Grunt版本（撰文時Grunt穩定版為0.4.5）和Plugin列表，因為開頭有提到，本案例以最小化的角度來介紹Grunt，所以用到的三個Plugin分別為：
- grunt-contrib-htmlmin：最小化HTML檔。
- grunt-contrib-cssmin：最小化CSS檔。
- grunt-contrib-uglify：最小化JS檔。
- 接下來利用Grunt的專案設定檔來安裝所需要的Grunt和各個外掛，利用「命令提示字元」進入網頁專案的根目錄，輸入「npm install」，他就會在專案資料夾中安裝好所有需要的Plugin。
安裝 Grunt 後的專案資料夾
- 接下來就要開始準備撰寫Grunt.js的執行腳本，大家可以參考我的專案檔案寫法：
module.exports = function (grunt) { grunt.initConfig({ htmlmin: { Target: { options: { removeComments: true, collapseWhitespace: true, removeEmptyAttributes: true, }, files: { 'public/index.html': 'src/index.html', } } }, cssmin: { target: { files: { 'public/index.css': 'src/index.css' } } }, uglify: { target: { files: { 'public/index.js': 'src/index.js' } } } }); grunt.loadNpmTasks('grunt-contrib-htmlmin'); grunt.loadNpmTasks('grunt-contrib-cssmin'); grunt.loadNpmTasks('grunt-contrib-uglify'); grunt.registerTask('default', ['htmlmin', 'cssmin', 'uglify']); };這樣的寫法會讓Grunt把在src裡面的三個檔案，分別壓縮後複製一份到public的資料夾中，確定資料夾和檔案無誤之後，繼續下一步動作。
- 利用「命令提示字元」進入網頁專案的根目錄，輸入「grunt」之後，出現以下的畫面表示成功。
Grunt 執行成功
- 本案例利用三個Grunt的Plugin完成，分別是：「grunt-contrib-htmlmin」、「grunt-contrib-cssmin」、「grunt-contrib-uglify」，其實這三個外掛都有一些其他的參數，另外也可以進行多檔案的批次轉換以及檔案合併…等等功能，建議有需要的同學可以到Plugin各自的網站上去看看使用方式。
附帶一提，一開始就有提到關於Grunt自動化的Plugin非常多，本文僅用到了三個，這裡有Plugin的列表，對這方面有興趣的同學們也歡迎到網站上看更多相關的自動化功能。
