Doesn't generate inline source maps about awesome-typescript-loader

[raveclassic]

Ran into this issue when tried to disable sourcemaps completely.
Looks like when "sourceMap": false is present in tsconfig, JSON.parse in compiler tries to parse undefined - this is how an error Module build failed: SyntaxError: Unexpected token u appears.

@raveclassic thanks for your report. I'll fix this.

@s-panferov Thanks!
Besides could you please investigate into disabling sourcemaps in general?
In my current workflow I use typescript transpiling to es6 and then pass result to babel. Somehow it appeared today that sourcemaps from typescript does not suit anymore to babel and it fails with invalid mapping error when receiving inputSourceMap
Sure it's problem with babel or typescript, but nevertheless I failed trying to disable sourcemapping in awesome-typescript-loader.

TIA

I have the same issue, and something more with the following configuration:

{
    resolve: {extensions: ['', '.ts', '.js']},
    watch: watch,
    module: {
      preLoaders: [{test: /\.ts$/, exclude: /node_modules/, loaders: ['tslint-loader']}],
      loaders: [{test: /\.ts$/, exclude: /node_modules/, loaders: ['ng-annotate', 'awesome-typescript-loader']}]
    },
    output: {
      filename: 'output.js'
    }
}

With this configuration, the file is generated BUT there are multiple

//# sourceMappingURL=my.typescript.original.file.js.map

directives for each included transpiled module, while in the end there is a

//# sourceMappingURL=output.js.map

as it should be.
This leads to errors while processing the source maps, since all the first maps are never found (are they temporary during the transpilation process?) as only the last one is actually generated.

Then I tried to set ?sourceMap=false to see if the issue could be fixed and I got the same error as the one reported by @nelo112.

This is similar to webpack/webpack#273 and also causes SitePen/remap-istanbul#20.

All problems with source maps might gone in v0.15.3, please try it.

At 0.15.3 and karma I'm still not getting sourcemaps at all with devtool: 'inline-source-map'.

config:

 {
            resolve: {
                extensions: ['', '.webpack.js', '.web.js', '.ts', '.tsx', '.js']
            },
            output: {
                devtoolModuleFilenameTemplate: "../[resource-path]",
                devtoolFallbackModuleFilenameTemplate:"../[resource-path]"
            },
            devtool: 'inline-source-map',
            module: {
                loaders: [
                    {
                        test: /\.tsx?$/,
                        loaders: ['awesome-typescript-loader'],
                    },
                    {
                        test: /\.json?$/,
                        loaders: ['json-loader']
                    }
                ]
            }
           }

tsconfig:

{
  "compilerOptions": {
    "target": "es6",
    "sourceMap": true,
    "jsx": "react",
    "experimentalDecorators": true,
    "experimentalAsyncFunctions": true
  },
  "awesomeTypescriptLoaderOptions": {
    "useBabel": true,
    "useCache": false,
    "emitRequireType": false
  }
}

@s-panferov I can confirm the fix, thanks!

How to configure the same for react native?
