Closes Caleydo/tdp_bi_bioinfodb#1317
Requires

Note also Caleydo/ordino_product#64, https://github.com/datavisyn/ordino_bi_vienna_product/pull/47

Summary

The issue was that the workers were being imported under the path app/ but they were available in the root directory
Added prefix tourdino to import path and added nginx path alias

Changes for the dev server

Extend devServerProxy object in your .yo-rc-workspace.json

"devServerProxy": {
    "/app/tourdino/*": {
      "target": "http://localhost:8080",
      "pathRewrite": {
        "^/app": ""
      },
      "secure": false
    }
  },
