json - Separate Angular2 TypeScript files and JavaScript files into different folders, maybe 'dist‘

Question

I am using the 5 min quickstart from angular.io website, which contain a file structure like this:

angular2-quickstart
 app
   app.component.ts
   boot.ts
 index.html
 license.md
 package.json
 tsconfig.json

the tsconfig.json is a code block like this ：

{
  "compilerOptions": {
    "target": "ES5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules"
  ]
} 

Also the package.json:

{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "lite": "lite-server",
    "start": "concurrent "npm run tsc:w" "npm run lite" "
  },
  "license": "ISC",
  "dependencies": {
    "angular2": "2.0.0-beta.0",
    "systemjs": "0.19.6",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.0",
    "zone.js": "0.5.10"
  },
  "devDependencies": {
    "concurrently": "^1.0.0",
    "lite-server": "^1.3.1",
    "typescript": "^1.7.3"
  }
}

I change the sourceMap from true to false, so in the code editor, the map file is not generated again, but the js file still get generated.

I want to work on only ts file and don't want to get a brunch of js and js.map file, what should I do to put all my ts files in my regular develop floder like app folder and all the js and js.map files into a folder called dist?

A good example of this might be angular2-webpack-quickstart. But I didn't figure out how they do that?

Any advice how to do that, of course not manually.

Thanks,

Answer 1

Probably late but here is a two-step solution.

Step 1

Change system.config.js by updating 'app' to 'dist/app':

var  map = {
    'app':                        'app', // 'dist/app',
    .
    .
    .
};

Now it will look like this:

var  map = {
    'app':                        'dist/app', // 'dist/app',
    .
    .
    .
};

Step 2

Create the dist folder.

Edit tsconfig.json and add:

"outDir": "dist"

The resulting tsconfig.json:

{
  "compilerOptions": {
    .
    .
    .
    .

    "outDir": "dist" // Pay attention here
  },
  "exclude": [
    .
    .
    .
  ]
}

Run npm start and you should see all the compiled .js and .map.js files in the dist folder.
