The source map does not currently work with the transformer pipeline.
It will be re-enabled after TypeScript 2.4 is made the min version.
To revert to the former compiler, use the `disableTransformerPipeline` in
tsconfig.json:
```
{
"angularCompilerOptions": {
"disableTransformerPipeline": true
}
}
```
To add a new server side rendering E2E test
- Add a new server side rendered application to src/
- Edit webpack.client.config.js to add new entry point for the new client bundle
- The index.html can access the client bundle from /built/.js
- Edit src/server.ts to add the server side application to a new URL
- Add a protractor test in e2e/ to test with the new URL
