I have an angular 4 app and I'm using webpack and awesome typescript loader to compile the Typescript into js for the build. When I run npm run start for local it works but when I run npm run build it doesn't compile the typescript files into js and I get the following errors:

Here is the webpack.config.js file for typescript: 

var atlOptions = '';
 if (isTest && !isTestWatch) {
 // awesome-typescript-loader needs to output inlineSourceMap for code coverage to work with source maps.
     atlOptions = 'inlineSourceMap=true&sourceMap=false';
  }

config.module = {
  rules: [
    // Support for .ts files.
  {
     test: /\.ts$/,
     loaders: ['awesome-typescript-loader?' + atlOptions, 'angular2-template-loader', '@angularclass/hmr-loader'],
    exclude: [isTest ? /\.(e2e)\.ts$/ : /\.(spec|e2e)\.ts$/, /node_modules\/(?!(ng2-.+))/]
  }

This is from the tsconfig.json file: 

  {
     "compilerOptions": {
     "target": "ES5",
    "module": "commonjs",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "sourceMap": true,
    "noEmitHelpers": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noStrictGenericChecks": true,
    "lib": ["es2015", "dom"]
  },
     "compileOnSave": false,
     "buildOnSave": false,
     "awesomeTypescriptLoaderOptions": {
     "forkChecker": true,
     "useWebpackText": true
  }
}

The dependencies used in this project are node 8.10.0, npm 6.1.0, webpack 2.6.1, awesome-typescript-loader 3.1.3, typescript 2.6.1

Is there something I left out?

when Run in local web-pack not check for all possible errors. If errors occurs just throw exceptions (In developing environment). But when building it check all errors that can be occurred in run time. you have have to fix these issues for building and get good build files.

  • All those issues are from the typescript not being compiled into valid javascript. Something is wrong with it compiling – MikeL5799 Oct 04 '18 at 16:20
  • are you saying that fixing those all errors not solved the problem? – Asanka Oct 04 '18 at 16:27
