When using the PNPM package manager, any dependecies not explicitly mentioned in the `package.json` will be ignored at time of package installation. The following code (found in `dist-web/index.js`) make the following reference to the `prop-types` package. ``` let PropTypes; try { PropTypes = require("prop-types"); } catch (e) {} ``` React apps throw an error, complaining that the `prop-types` package could not be resolved. The fix, is to add `prop-types` as a dependency in the `package.json`. I will commit a PR to hopefully which fixes the issue.
