metadata is undefined (Babel)

See original GitHub issue

I create a simple advice just like Get Started, but advices can’t find metadata.

  • simple react demo project
  • kaop-ts v1.2.0


import React, {Component} from 'react';
import logo from './logo.svg';
import './App.css';
import {afterMethod} from 'kaop-ts'
import {MyAdvices} from './MyAdvices'

class App extends Component {

  constructor(props) {
    this.handleClick = this.handleClick.bind(this);

  handleClick() {
    alert('You Click It!');

  render() {
    return (
      <div className="App">
        <div className="App-header" onClick={this.handleClick}>
          <img src={logo} className="App-logo" alt="logo"/>
          <h2>Welcome to React</h2>
        <p className="App-intro">
          To get started, edit
          and save to reload.

export default App;


import { AdvicePool, adviceMetadata } from 'kaop-ts'

export class MyAdvices extends AdvicePool {
  static doubleResult (@adviceMetadata metadata) {
    console.log(metadata);     // always output undefined here

@k1r0s gread job!

Although I prefer to use typescript now, but there are a lot of people use original javasciprt,which is very useful for them.

Thanks a lot @k1r0s ,

It is difficult to replace the whole project into typescript, but I wirte advices files use typescript (that I learned just last weekend 😛) according to your suggestion, use babel for other .js files, it works fine now!

I also will keep an eye on this, thanks for you libarary!
