Hey @sjparsons, thanks for this. It definitely sounds like a useful feature, thanks! I will review it quite soon as I am gonna be doing some updates to this lib. 👍

Hey @sjparsons, so I have updated this library to use the latest version of react-tree-walker. At the same time I reviewed the options we were passing down to react-tree-walker. I have now exposed the ability to provide a React "context" to your component tree for bootstrapping. This essentially can satisfy your requirements in an alternative manner.

e.g.

class Foo extends Component {
 bootstrap() {
 console.log(this.context.myBootstrapSetting)
 }
 render() {
 return <div>foo</div>
 }
}
bootstrapper(<Foo />,null,{myBootstrapSetting:'what_ever_you_need'})
 .then(() => console.log('done'))

As you can see it's a new third parameter to the bootstrapper.

I think it would be best to keep the secondary options parameter separate and specific to the bootstapper/react-tree-walker configuration.

What do you think?

You may have noticed I am using bootstrap instead of asyncBootstrap. Both work, however, asyncBootstrap will be removed in next major release.
