How to unminify the js files?
提问by Adarsha Beleyur
How can I unminify js file which is minify from webpack tool.
如何取消从 webpack 工具缩小的 js 文件。
Before minify,
在缩小之前，
function autoslideSlider() {
$('.next-slide').trigger('click');
}
$(window).on('load', function(){
$('.preloader').fadeOut('fast');
$('#after_load').addClass('show');
setInterval(autoslideSlider, 8000);
});
$('a').on('click', function () {
if (location.pathname.replace(/^\//, '') === this.pathname.replace(/^\//, '') && location.hostname === this.hostname) {
var $target = $(this.hash);
$target = $target.length && $target;
// $('[name=' + this.hash.slice(1) + ']');
if ($target.length) {
var targetOffset = $target.offset().top - 20;
$('html,body').animate({
scrollTop: targetOffset
}, 1500);
return false;
}
}
});
After minify,
缩小后，
!function(e){var t={};function n(o){if(t[o])return t[o].exports;var r=t[o]={i:o,l:!1,exports:{}};return e[o].call(r.exports,r,r.exports,n),r.l=!0,r.exports}n.m=e,n.c=t,n.d=function(e,t,o){n.o(e,t)||Object.defineProperty(e,t,{configurable:!1,enumerable:!0,get:o})},n.r=function(e){Object.defineProperty(e,"__esModule",{value:!0})},n.n=function(e){var t=e&&e.__esModule?function(){return e.default}:function(){return e};return n.d(t,"a",t),t},n.o=function(e,t){return Object.prototype.hasOwnProperty.call(e,t)},n.p="",n(n.s=0)}([function(e,t){function n(){$(".next-slide").trigger("click")}$(window).on("load",function(){$(".preloader").fadeOut("fast"),$("#after_load").addClass("show"),setInterval(n,8e3)}),$("a").on("click",function(){if(location.pathname.replace(/^\//,"")===this.pathname.replace(/^\//,"")&&location.hostname===this.hostname){var e=$(this.hash);if((e=e.length&&e).length){var t=e.offset().top-20;return $("html,body").animate({scrollTop:t},1500),!1}}})}]);
How can I unminify the above js file?

You can't unminify a minified file. Minification is a desctructive operation and involves loss of information.
您无法取消缩小缩小的文件。缩小是一种破坏性操作，涉及信息丢失。
For example, if you have a function with a descriptive name, after minifcation that name will be substitute with a meaningless one. There's no way to go back from this operation.
例如，如果您有一个具有描述性名称的函数，则在缩小后该名称将被替换为无意义的名称。没有办法从这次行动中回来。
You can use a beautifierto make it more readable, but you will have a weighty job of reverse engineering in order to understand what the code means.
您可以使用美化器使其更具可读性，但是为了理解代码的含义，您将有一项繁重的逆向工程工作。

source-maps are what you want. in the process of making a minified js file, you should get a source-map file, too (it depends on what tool you use for minification).
源映射就是你想要的。在制作一个缩小的 js 文件的过程中，你也应该得到一个 source-map 文件（这取决于你使用什么工具进行缩小）。
Then using source-maplibrary you can recover the original files.
然后使用源映射库您可以恢复原始文件。
If the source-mapfile does include the minified source, this file is enough to unminify. otherwise, you have to tell the library the minified source manually.
如果source-map文件确实包含缩小的源，则该文件足以取消缩小。否则，您必须手动告诉库缩小的源。
More info, on the library's Github page.

There is a tool online that will allow you to do this.
有一个在线工具可以让您做到这一点。
But as stated by Archer, anything obfuscated will remain.
但正如 Archer 所说，任何混淆的东西都会保留下来。
