Nested Routers

[posva]

What problem does this feature solve?

Allow using nested memory routers to handle independent views. e.g. the messages on Twitter, or a chat.

A custom History implementation could even save the current page in local storage and restore it when reopening the app.

What does the proposed API look like?

provideRouter(createRouter(...))
// or
createNestedRouter(baseRouterOptions)

• Could warn if history is based on HTML5
• No initial navigation
• Should provide these
• Could appear in devtools
• Could automatically unregister the history listener on unmounted
• Should not change global configs
• Should still be able to access the global router

This would have to go through an RFC to better identify the different needs of creation/destruction of nested routers.
