Use with react-hot-loader

[iam4x]

Using alt with react-hot-loader loader in webpack, throw me random errors:

Cannot not apply hot update to users.jsx: A store named UserStore already exists, double check your store names or pass in your own custom identifier for each store

I couldn't find what isn't working, went through this issue: moreartyjs/todomvc-moreartyjs#2

Maybe something with the context?

It sounds like it's recreating the stores which is not a good thing. I'll take a closer look at this. If you have any code you can share please do :)

Edit app/component/users.jsx with changing something in render() twice, it will be thrown in the console.

Would love for this to work, this is one of the major pains with react-hot-loader and alt. It reloads the relevant changed scripts so I thought it just couldn’t be fixed easily. 👍

So it's a webpack bug:

webpack/webpack#826

Let me think of ways to get around this in the meantime

Yeah it's a Webpack bug. It's been annoying for months but I just got around to isolating it yesterday. Hopefully the fix is in the works!

[goatslacker]

Fixed by webpack :)

[gaearon]

You'll need to update Webpack to 1.7.0 to get the fix.

Hmm.. I am still receiving this error on Webpack 1.7.3, any thoughts @gaearon @goatslacker @iam4x?

[frederickfogerty]

Double check you are on the latest version - ever since I upgraded to 1.7 I haven't had this issue

Yeah, I am on 1.7.3 and still get the error when I make some code changes to a Store and then save, is this a different issue entirely?

[gaearon]

The original bug is about changing the component:

Edit app/component/users.jsx with changing something in render() twice, it will be thrown in the console.

If you make changes in the store, there's nothing RHL can do: it doesn't know how to handle updates in an Alt store (at least not just yet :-). It only updates components, and files which are required only by components. So yeah, changing the store will throw app into an inconsistent state and you need to either manually refresh, or use hot/dev-server instead of hot/only-dev-server to refresh automatically.

Ah I see, thanks for the clarification!

[goatslacker]

Actually let me open a new ticket.
