混淆

🌐 Mangling

Oxc 压缩器支持混淆变量名称和私有类字段。

🌐 Oxc minifier supports mangling variable names and private class fields.

此功能默认启用，可以通过将 mangle 选项设置为 false 来禁用。

🌐 This feature is enabled by default and can be disabled by setting the mangle option to false.

顶层变量

🌐 Top Level Variables

默认情况下，顶层变量对于非模块代码不会被混淆。你可以通过将 mangle.toplevel 选项设置为 true 来启用顶层变量的混淆。

🌐 Top level variables are not mangled by default for non module code. You can enable mangling for top level variables by setting the mangle.toplevel option to true.

// input
var foo = 1;

// output
var e = 1;

// Example
import { minify } from "oxc-minify";

const result = await minify("lib.js", code, {
  module: false, // non-module code
  compress: {
    mangle: {
      toplevel: true,
    },
  },
});

保留 name 属性值

🌐 Keep name Property Values

混淆变量名可能会更改函数/类的 name 属性值。通过启用 mangle.keepNames 选项，你可以保留原始的 name 属性值。

🌐 Mangling variable names can change the name property values of functions / classes. You can keep the original name property values by enabling the mangle.keepNames option.

// input
var foo = function () {};

// output
var foo = function () {};

// Example
import { minify } from "oxc-minify";

const result = await minify("lib.js", code, {
  compress: {
    mangle: {
      keepNames: true, // shorthand of { function: true, class: true }
    },
  },
});

compress.keepNames 选项

启用此选项时，你可能还想启用‘compress.keepNames’选项。

🌐 When enabling this option, you may also want to enable the compress.keepNames option.

调试碎纸机

🌐 Debugging The Mangler

要调试混淆器，你可以启用 mangle.debug 选项。启用此选项后，混淆器将使用 slot_0、slot_1 等作为变量名。

🌐 To debug the mangler, you can enable the mangle.debug option. When this option is enabled, the mangler will use slot_0, slot_1, ... as variable names.

// input
var foo = 1;

// output
var slot_0 = 1;

// Example
import { minify } from "oxc-minify";

const result = await minify("lib.js", code, {
  compress: {
    mangle: {
      debug: true,
    },
  },
});
