Install:

   1.ionic start myapp blank 

    2.cd myapp

    3.npm install cordova-uglify 

or npm install cordova-uglify --legacy-bundling

Useage:

1.找到hooks/uglify-config.json

2.将第一行代码"alwaysRun": 

false 改为"alwaysRun": 

true,

3.运行ionic platform add android,ionic build android 

4.查看plaforms/android/assets/www/目录下的所有文件，是否uglify和minify

U福利：(自动js纠错功能) 

1.安装：

npm install jshint

npm install async

2.手动新建文件

 在hooks目录下新建文件夹“before_prepare”,该文件夹下新建文件“02_jshint.js”

 将以下内容粘贴到新建文件里:

 

1 #!/usr/bin/env node 2   3 var fs = require('fs'); 4 var path = require('path'); 5 var jshint = require('jshint').JSHINT; 6 var async = require('async'); 7   8 var foldersToProcess = [ 9     'js'10 ];11  12 foldersToProcess.forEach(function(folder) {13     processFiles("www/" + folder);14 });15  16 function processFiles(dir, callback) {17     var errorCount = 0;18     fs.readdir(dir, function(err, list) {19         if (err) {20             console.log('processFiles err: ' + err);21             return;22         }23         async.eachSeries(list, function(file, innercallback) {24             file = dir + '/' + file;25             fs.stat(file, function(err, stat) {26                 if(!stat.isDirectory()) {27                     if(path.extname(file) === ".js") {28                         lintFile(file, function(hasError) {29                             if(hasError) {30                                 errorCount++;31                             }32                             innercallback();33                         });34                     } else {35                         innercallback();36                     }37                 } else {38                     innercallback();39                 }40             });41         }, function(error) {42             if(errorCount > 0) {43                 process.exit(1);44             }45         });46     });47 }48  49 function lintFile(file, callback) {50     console.log("Linting " + file);51     fs.readFile(file, function(err, data) {52         if(err) {53             console.log('Error: ' + err);54             return;55         }56         if(jshint(data.toString())) {57             console.log('File ' + file + ' has no errors.');58             console.log('-----------------------------------------');59             callback(false);60         } else {61             console.log('Errors in file ' + file);62             var out = jshint.data(),63             errors = out.errors;64             for(var j = 0; j < errors.length; j++) {65                 console.log(errors[j].line + ':' + errors[j].character + ' -> ' + errors[j].reason + ' -> ' +66 errors[j].evidence);67             }68             console.log('-----------------------------------------');69             callback(true);70         }71     });72 }

 

3.重新运行ionic build android

　将在编译过程看到一下代码

 

表示你的js代码没有错误！
