instructions.txt

// Bellow instructions how to run a build with BabelJs. After following them, just run in CLI: `sencha app build` or `npm run build`

// 1. In app.json
"production": {
   "output": {
      "framework": {
        "enable":true //This enables split mode, app code will be splitted in 2 files: app.js and framework.js
      }
    }
 },
 "output": {
    "js": {
      "version": "ES8"
    }
  },
  "language": {
    "js": {
      "input": "ES8"
    }
  }
   
//2. In build.xml
