If "full reload needed" does this need to be manually? about react-transform-boilerplate

Webpack hot module updates follow the import chain. As long as a module “ends up” being imported from components only, hot updates will work. If a specific module import chain ends in something like index.js which is not a component, hot updates will fail because react-transform-hmr has no idea how to handle updates to something other than components.

That said you can write manual code to handle hot updates of modules that don’t end up consumed by components. For example, this is how we hot replace reducers in Redux.

Is there a way to plugin to the React HMR features to extend it and make it aware of my code?

I'm working on code that reads config in JSON and creates React elements on the fly, so the HMR proxying doesn't work. I basically have a top-level function that returns a React Router element, which delegates to functions that create React component classes through currying. My goal is changes the JSON configuration file triggering hot updates to the React app produced by that json->react transform function.

If this use case isn't a good fit for React HMR, that's a totally reasonable answer -- I've considered implementing json config->React app as a compile-time transform (probably as a webpack loader for the JSON config file).

Do you care about preserving component local state (this.state) on hot reloads? If not, just don’t use proxying and use raw HMR API to replace the whole component subtree with a new version like here.

Oh that's awesome and exactly what I need, thanks!
