【Help】Using the export keyword between a decorator and a class is not allowed. Please use export @dec class instead

[fanksy]

Swc4jTranspileOptions options = new Swc4jTranspileOptions()
                .setCaptureAst(true)
                .setUseTsDecorators(true)
                .setUseDecoratorsProposal(true)
                .setEmitMetadata(false)
                .setMediaType(getMediaType(path));

请问该如何设置才能正常解析

有一个相关的issue：babel/babel-eslint#662

解决方式：

"parserOptions": {
    "ecmaFeatures": {
      "legacyDecotators": true
    }
  }

这个在Options里面没有对应的选项

I fail to see there's anything wrong. Please check this commit out.

import React from 'react';
import { connect } from 'react-redux';

const ConditionModal = loadable(() => import('components/ConditionModal'));

@connect((state) => {

  return {
  };
})
export default class MyComponent extends React.Component {
  componentDidMount() {}

  render() {
    const {
      visible,
    } = this.props;
    return (

        {true && <ConditionModal />}
      </>

Swc4jTranspileOptions options = new Swc4jTranspileOptions()
.setCaptureAst(true)
.setMediaType(Swc4jMediaType.Jsx);

Swc4jParseOutput parseOutput = swc4j.parse(script, options);
Swc4jAstModule module = (Swc4jAstModule) parseOutput.getProgram();

I hope this can help you to figure it out.

Please set the media type to Tsx and try again.

测试OK

Tsx完全兼容Jsx ？

Jsx都可以用Tsx来解析？

[caoccao]

I think it's your decision to parse the templates as Jsx or Tsx.
