v1.9.0

Performance

Deobfuscation and readability transforms are now significantly faster

New Features

Modules can get converted to ESM:

require.r(exports);
require.d(exports, 'Counter', function () {
  return f;
});
class f {}

->

export class Counter {}

This, together with changes to some other webpack functions, will allow unpacked modules to be repacked and run instead of the original bundle:

npx webpack-cli ./webcrack-out

v1.8.0

New Features

• Merge nested else if:

if (x) { } else { if (y) {} }

->

if (x) {} else if (y) {}

Bug Fixes

• Handle string decoder returning undefined by @Sorte1 in #1

v1.7.0

New Features

• Add block statement to arrow functions:

(e) => ((e.x *= -1), (e.y *= -1), e)

->

e => {
  e.x *= -1;
  e.y *= -1;
  return e;
};

v1.6.2

Bug Fixes

• Bundle mappings get applied again when saving

v1.6.1

Improvements

• Apply mappings after instead of before saving bundle so it's still executable

v1.6.0

Improvements

• Warns about mapping issues
• Convert computed properties with classes, optional chaining

v1.5.1

Fixes

v1.5.0

New Features

• multiple clean-up iterations: webcrack --max-iterations 10
• bypass debug protection when decoding strings
• merge strings: "a" + "b" + "c" -> "abc"
• deterministic ternaries: "abc" == "abc" ? a() : b() -> a()
• normalize computed object properties and methods: { ["abc"]: 1, ["xyz"]() {} } -> { abc: 1, xyz() {} }
• extract sequence from switch: switch(a(), b(), c()) { ... } -> a(); b(); switch(c()) { ... }

Improvements

• match array rotator in more cases
• convert more computed properties in member expressions: exports["default"] -> exports.default

v1.4.0

• Simplify deterministic if statments: if ("xyz" === "xyz")
• Ternary to if
• Unpack webpack object format
• Transform code option

Improvements

• String array rotator matcher
