ionic 2 typescript source map not created

Question

I am trying to debug Ionic 2 Application And I want to know how to include souceMap for every typescript file that maps to the javascript files.

But when I open the dev tools in Chrome there is no any souceMap file.

Also, I enabled the "sourceMap":true in tsconfig.json file. This is my tsconfig.json file

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
      "dom",
      "es2015"
    ],
    "module": "es2015",
    "moduleResolution": "node",
    "sourceMap": true,
    "target": "es5",
    "types": [
      "jasmine"
    ]
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ],
  "compileOnSave": false,
  "atom": {
    "rewriteTsconfig": false
  }
}

After that, I tried changing the ionic.config.json according to this sourcemaps not working for ionic 2. But it also did not work for me.

Does anyone know what is wrong?

Answer 1

found the answer.

Still .map files are not generated. Because it is a bug see this issue. But now I can debug after adding this

"config":{

     "ionic_source_map":"source_map"
}

into package.json file. Now all the .ts files are shown in the debug mode.
