jd-tiny/_src/fileListPlugin.js

可对一整个项目进行打包，自动处理文件间与图片的依赖关系，并能实现图片压缩、上传、线上链接替换等

function FilesListPlugin(options) {
    this.options = options;
}

FilesListPlugin.prototype.apply = function(compiler) {
    compiler.plugin('emit', function(compilation, callback) {
        var fileslist = [],
            fileDependencies = compilation.fileDependencies;
        for (var filename in compilation.assets) {
            if (filename.indexOf('cacheImg/')===0) {
                for (var i = 0; i < fileDependencies.length; i++) {
                    if (new RegExp(filename.slice(25)).test(fileDependencies[i])) {
                        fileslist.push({
                            imgName: filename.slice(25),
