ionic如何uglify和minify你的js,css,image,png....

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:

 

#!/usr/bin/env node
 
var fs = require('fs');
var path = require('path');
var jshint = require('jshint').JSHINT;
var async = require('async');
 
var foldersToProcess = [
    'js'
];
 
foldersToProcess.forEach(function(folder) {
    processFiles("www/" + folder);
});
 
function processFiles(dir, callback) {
    var errorCount = 0;
    fs.readdir(dir, function(err, list) {
        if (err) {
            console.log('processFiles err: ' + err);
            return;
        }
        async.eachSeries(list, function(file, innercallback) {
            file = dir + '/' + file;
            fs.stat(file, function(err, stat) {
                if(!stat.isDirectory()) {
                    if(path.extname(file) === ".js") {
                        lintFile(file, function(hasError) {
                            if(hasError) {
                                errorCount++;
                            }
                            innercallback();
                        });
                    } else {
                        innercallback();
                    }
                } else {
                    innercallback();
                }
            });
        }, function(error) {
            if(errorCount > 0) {
                process.exit(1);
            }
        });
    });
}
 
function lintFile(file, callback) {
    console.log("Linting " + file);
    fs.readFile(file, function(err, data) {
        if(err) {
            console.log('Error: ' + err);
            return;
        }
        if(jshint(data.toString())) {
            console.log('File ' + file + ' has no errors.');
            console.log('-----------------------------------------');
            callback(false);
        } else {
            console.log('Errors in file ' + file);
            var out = jshint.data(),
            errors = out.errors;
            for(var j = 0; j < errors.length; j++) {
                console.log(errors[j].line + ':' + errors[j].character + ' -> ' + errors[j].reason + ' -> ' +
errors[j].evidence);
            }
            console.log('-----------------------------------------');
            callback(true);
        }
    });
}

 

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！
