Runtime dependencies faulty declared as devDependencies.

[PerThoresson]

Some dependencies are declared as dev dependencies while they are actually run-time dependencies. This does not cause a problem with NPM currently as other dependencies include the missing ones.

However, when using together with Bazel and rules_js which isolate dependencies it breaks as they are not declared properly.

I've fixed the package.json to declare the dependencies in the correct way.

Thanks!
