@mariozechner/jailjs/dist/transform.d.ts

Lightweight JavaScript interpreter for isolated execution. For plugins, user scripts, and browser extensions. Not for adversarial code - use SandboxJS or isolated-vm for that.

import type * as t from "@babel/types";
/**
 * Transform modern JavaScript (ES6+) to ES5 AST for interpreter execution
 *
 * This function uses Babel to transform modern JavaScript syntax to ES5,
 * then parses it into an AST. The resulting AST can be executed by the interpreter.
 *
 * @param code - Modern JavaScript code (ES6+, TypeScript, JSX, etc.)
 * @param options - Babel transformation options
 * @returns ES5 AST Program node
 *
 * @example
 * ```typescript
 * import { Interpreter } from '@mariozechner/jailjs';
 * import { transformToES5 } from '@mariozechner/jailjs/transform';
 *
 * const modernCode = `
 *   const double = (x) => x * 2;
 *   const numbers = [1, 2, 3];
 *   numbers.map(double);
 * `;
 *
 * const ast = transformToES5(modernCode);
 * const interpreter = new Interpreter();
 * const result = interpreter.evaluate(ast);
 * console.log(result); // [2, 4, 6]
 * ```
