Do the traversal of the source directory structure

$ npm install dir-ls --save

with options mode:

let ls = require('dir-ls')

ls('./someDir', {
    readMode: 'utf8',
    justFind: /png|jpg|gif/,
    dirCallback(res) {
        //do something here
    },
    fileCallback(res) {
        //do something here
    },
    errorHandle(err) {
        //handle error
    },
    allDone(){
        //dir-ls have been finished
    }
})

without options mode:

let ls = require('dir-ls')

ls('./someDir', function(res){
    //equal to fileCallBack
})
