I'm having trouble getting this app to compile the TypeScript files into JavaScript using webpack and the awesome TypeScript loader. What could be causing this issue?

Currently running an angular 4 app with webpack and awesome typescript loader to compile Typescript into js for the build. Local execution using npm run start functions correctly, but when attempting npm run build, typescript files fail to compile to js resulting in the following errors:

ERROR in [at-loader] ./src/components/app.module.ts:21:39 
    TS2305: Module '"/Users/*******/Desktop/*****/src/services/index"' does not export member 'ArticlesService'.

Below is a snippet from webpack.config.js file used for typescript configuration:

var atlOptions = '';
 if (isTest && !isTestWatch) {
     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 excerpt is taken from the tsconfig.json file:

  {
     "compilerOptions": {
     "target": "ES5",
    "module": "commonjs",
    "emitDecoratorMetadata": true,
    ...
  },
     "compileOnSave": false,
     ...
}

Dependencies utilized in this project include node 8.10.0, npm 6.1.0, webpack 2.6.1, awesome-typescript-loader 3.1.3, typescript 2.6.1

Any insights on what could have been overlooked?

Answer №1

During local web-pack execution, not all potential errors are verified for. Only exceptions are thrown if errors occur (during development). However, during the build process, all possible errors that may arise at runtime are checked. It is crucial to address and rectify these issues in order to achieve high-quality build files.
