如何使用 nightmare.js 库混淆 JS 文件

Question

当我在 macOS 上打包电子应用程序时，由于其局限性，我永远无法使用 Nightmare 混淆文件。我是否需要重新编写整个库，或者有什么办法可以解决这个问题？

有一个解决方案。绝对不稳定且未经测试，请自行承担风险。而且，如果您能找到并修复作为副作用出现的错误，请随时分享它们:)

我们将使用一个名为pkg 的模块将脚本与node 捆绑在一起。同样为简单起见，我们将使用npx。

有一些副作用，但这是第一次使用 electron 和 nightmare。

考虑以下脚本，

const Nightmare = require("nightmare");
const nightmare = Nightmare({
  show: true
});

nightmare
  .goto("https://example.com")
  .title()
  .end()
  .then(console.log)
  .catch(error => {
    console.error(error);
  });

这是一个简单的脚本，上面写着，转到example.com 并给我标题。

酷！让我们尝试通过npx 和pkg 使用它。代码是，

npx pkg app.js --target 'host'

但是，我们遇到了一些严重的错误，

> Warning Cannot include file %1 into executable.
  The file must be distributed with executable as %2.
  node_modules/nightmare/lib/runner.js
  path-to-executable/nightmare/runner.js
> Warning Cannot include file %1 into executable.
  The file must be distributed with executable as %2.
  node_modules/nightmare/lib/frame-manager.js
...

等等等等，文件不会运行。

Error: spawn /home/someone/Desktop/a/electron/dist/electron ENOENT

找不到所需的文件，因为它们没有捆绑在一起。我们将使用process.cwd() 来获取驻留在相关文件夹中的那些数据。

const nodeDir = process.cwd() + "/node_modules/"; // <- Get node modules folder 
const nightmareDir = nodeDir + "nightmare"; // <-- Get nightmarejs path
const electronDir = nodeDir + "electron"; // <-- Get electron path

const Nightmare = require(nightmareDir);
const electronPath = require(electronDir);

const nightmare = Nightmare({
  show: true,
  electronPath // <-- use the specific electron path
});

nightmare
  .goto("https://example.com")
  .title()
  .end()
  .then(console.log)
  .catch(error => {
    console.error(error);
  });

当我运行它时，它向我显示了更多警告，但那是因为我还没有优化 process.cwd()。然后我运行它，瞧！

➜  a npx pkg app.js --target 'host'
> pkg@4.3.1
> Warning Cannot resolve 'nightmareDir'
  /home/someone/Desktop/a/app.js
  Dynamic require may fail at run time, because the requested file
  is unknown at compilation time and not included into executable.
  Use a string literal as an argument for 'require', or leave it
  as is and specify the resolved file name in 'scripts' option.
> Warning Cannot resolve 'electronDir'
  /home/someone/Desktop/a/app.js

➜  a ./app
Example Domain // <-- Our sweet result :D 
➜  a

这可以改进和调整，但我会把它留给你。
