Use quickjs-emscripten package execute javascript code

[Siykt]

Manifest Version 3 restricts the use of sandboxing. We might consider using quickjs-emscripten package to implement the execution of JavaScript code.

If users need to manipulate the DOM, they can refer to Playwright's JSHandle for implementation.

demo:

import { getQuickJS } from 'quickjs-emscripten';

export async function executeJavascriptCode(refData, code) {
  const QuickJS = await getQuickJS()
  const vm = QuickJS.newContext()

  const varName = "REF_DATA"
  const result = vm.unwrapResult(
    vm.evalCode(`
    var ${varName} = ${JSON.stringify(refData)}
    function automaSetVariable(name, value) {
      const variables = ${varName}.variables;
      if (!variables) ${varName}.variables = {}
      ${varName}.variables[name] = value;
    }

    function automaRefData(keyword, path = '') {
      if (!keyword) return null;
      if (!path) return ${varName}[keyword];
      return ${varName}[keyword][path];
    }

    function automaNextBlock() {
      return new Promise((resolve) => {
        resolve(${varName})
      });
    }
    ${code}
`)
  )

  const promise = result.consume(result => vm.resolvePromise(result))

  vm.runtime.executePendingJobs()

  const asyncResult = vm.unwrapResult(await promise)

  const resultValue = vm.dump(asyncResult)

  asyncResult.dispose()
  vm.dispose()

  return resultValue
}
