A JavaScript obfuscator that converts code into cursed spell-like syntax.
``bash`
npm install curse-scriptor
pnpm add curse-script
`typescript
import { curse } from 'curse-script';
// Default: uses Runic characters
const cursed = curse('console.log("Hello World")');
console.log(cursed);
// Use Old Persian characters
const cursedPersian = curse('console.log("Hello World")', { characterSet: 'oldPersian' });
console.log(cursedPersian);
// Use emoji characters
const cursedEmoji = curse('console.log("Hello World")', { characterSet: 'emoji' });
console.log(cursedEmoji);
// Use custom character set (Greek alphabet)
const customChars = ['α', 'β', 'γ', 'δ', 'ε', 'ζ', 'η', 'θ', 'ι', 'κ', 'λ', 'μ', 'ν', 'ξ', 'ο', 'π', 'ρ', 'σ', 'τ', 'υ', 'φ', 'χ', 'ψ', 'ω'];
const cursedGreek = curse('console.log("Hello World")', { characterSet: customChars });
console.log(cursedGreek);
// No character replacement (Latin A-X)
const cursedLatin = curse('console.log("Hello World")', { characterSet: 'none' });
console.log(cursedLatin);
`
Run the interactive converter to test your scripts:
`bash`
pnpm run dev
This will start an interactive prompt where you can enter any JavaScript code and see it converted to curse-script format in real-time.
Example session:
`
Enter script to convert (or "exit" to quit): console.log("hi?")
Original:
console.log("hi?")
Cursed Output:

Converts JavaScript code into curse-script format.
Parameters:
- source: The JavaScript code to convertoptions.includePrelude
- : Whether to include the prelude (default: true)options.characterSet
- : Character set to use for obfuscation (default: 'runic')'runic'
- : Use Runic characters (ᚠ-ᚷ)'oldPersian'
- : Use Old Persian cuneiform (𐎠-𐎷)'emoji'
- : Use emoji characters (😀-😗)'none'
- : No character replacement (use Latin A-X)string[]
- : Custom array of at least 24 characters
Returns: The cursed script as a string
Examples:
`typescript
// With Runic characters (default)
curse('alert(1)'); // ᚠ='',ᚡ=!ᚠ+ᚠ,...
// With Old Persian characters
curse('alert(1)', { characterSet: 'oldPersian' }); // 𐎠='',𐎡=!𐎠+𐎠,...
// With emoji characters
curse('alert(1)', { characterSet: 'emoji' }); // 😀='',😁=!😀+😀,...
// With custom characters
const customChars = ['α', 'β', 'γ', 'δ', 'ε', 'ζ', 'η', 'θ', 'ι', 'κ', 'λ', 'μ', 'ν', 'ξ', 'ο', 'π', 'ρ', 'σ', 'τ', 'υ', 'φ', 'χ', 'ψ', 'ω'];
curse('alert(1)', { characterSet: customChars }); // α='',β=!α+α,...
// With no character replacement
curse('alert(1)', { characterSet: 'none' }); // A='',B=!A+A,...
`
When providing a custom character set:
- Must contain at least 24 unique characters
- Characters will map to variables A-X in order
- Can use any Unicode characters including emoji, symbols, or letters from any script
The package exports the built-in character sets for reference:
`typescript
import { RUNIC_CHARS, OLD_PERSIAN_CHARS, EMOJI_CHARS } from 'curse-script';
console.log(RUNIC_CHARS); // ["ᚠ", "ᚡ", "ᚢ", ...]
console.log(OLD_PERSIAN_CHARS); // ["𐎠", "𐎡", "𐎢", ...]
console.log(EMOJI_CHARS); // ["😀", "😁", "😂", ...]
// You can also use them as a base for custom modifications
const customSet = [...RUNIC_CHARS];
customSet[0] = '🔥'; // Replace first character
`
