I'm submitting a bug report

  • Library Version:

Please tell us about your environment:

  • Operating System:
    Ubuntu 16.04

  • Node Version:

  • NPM Version:
  • Browser:

  • Language:
    TypeScript 2.7.2

  • Loader/bundler:

Current behavior:
You can create a new cli project and choose typescript and webpack defaults.

Install aws-amplify, yarn add aws-amplify

In main.ts, import Amplify from 'aws-amplify'.

And call Amplify.configure({...}).

Running au run fails with json errors,

ERROR in ./node_modules/aws-sdk/lib/region_config_data.json
Module parse failed: Unexpected token m in JSON at position 0
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token m in JSON at position 0
    at JSON.parse (<anonymous>)
    at JsonParser.parse (node_modules/webpack/lib/JsonParser.js:15:21)
  • What is the expected behavior?
    Following the above steps should compile the app correctly.
  • What is the motivation / use case for changing the behavior?
    aws-amplify should work with aurelia cli.

So I removed the json loader line from webpack.config.js, the app compiled and I could use the amplify library. Webpack docs also say that json-loader isn't required for webpack 2 and above. If this is the correct fix, I can send a PR. Otherwise, pls suggest what I might be missing. Thanks.
