regeneratorRuntime is not defined

[bondanherumurti]

i tried to use the async function to integrate with react-relay and it seems it does not support the function

anyone experience this, and i tried several steps including installing babel-polyfill but it still not working, any idea?

@bondanherumurti Try this in .babelrc and remove babel-polyfill since that's natively supported in the version of node you are using.

"targets": {
   "node": "current"
 }

[bondanherumurti]

{
  "presets": [
    [
      "env",
      {
        "modules": false,
        "targets": {
          "node": "current",
          "browsers": "> 1%",
          "uglify": true
        },
        "useBuiltIns": true
      }
    ],
    "react"
  ],
  "plugins": [
    "syntax-dynamic-import",
    [
      "transform-class-properties",
      {
        "spec": true
      }
    ],
    "relay"
  ]
}

tried this on my .babelrc still not working

[gauravtiwari]

Try this please

{
  "presets": [
    [
      "env",
      {
        "modules": false,
        "targets": {
          "node": "current"
        }
      }
    ],
    "react"
  ],

  "plugins": [
    "relay",
    "syntax-dynamic-import",
    [
      "transform-class-properties",
      {
        "spec": true
      }
    ]
  ]
}
