Start testing Fiber

[rauchg]

react@16.0.0-alpha.2
react-dom@16.0.0-alpha.2

We'll need to use the following:
require('react-dom/fiber')

Here's an example on how to opt into low priority updates:

React 16 Beta is out now for public testing.

facebook/react#10294

[sergiodxa]

I just tried Next.js with React 16 Beta and it throw this error.

It looks like Next.js is using a internal lib and React 16 doesn't expose them anymore.

[gaearon]

Yes, nothing in /lib/ will be exposed in 16. Happy to discuss specific use cases for internals in facebook/react#10294.

[arunoda]

@gaearon Thanks.
We've a PR for this: https://github.com/zeit/next.js/pull/2570/files

Basically we want to track errors happening inside the component.
In the ^^ above PR, is uses some method in Fiber.

Is that the way we should do it?

[arunoda]

@gaearon I started it here: #2659
Let me know I'm doing it good here.

[gaearon]

Seems reasonable to me.
Note that this isn’t supported on server side yet (but normal catch works there).

[arunoda]

Yeah! I got that. (Actually, that's good in a sense)
We've already catch errors on the server. So, I hope we are good to go.

This also happens when trying to switch to Preact (and using the example provided).

 ERROR  Failed to compile with 1 errors                                                                                      7:40:58 PM

This module was not found:

* react-dom/lib/ReactReconciler in ./~/next/dist/client/next-dev.js

To install it, you can run: npm install --save react-dom/lib/ReactReconciler
> Ready on http://localhost:3000

[dmbaranov]

So React 16 is out now, any updates about it? Because I still have an error:

* react-dom/lib/ReactReconciler in ../node_modules/next/dist/client/next-dev.js

To install it, you can run: npm install --save react-dom/lib/ReactReconciler

[bntzio]

Yeah me too @dmt-13

[jesseditson]

@dmt-13 and @bntzio : as per latest README (not sure when it was updated), you'll either need to use next@beta to use react 16+, or if you want to use stable next, install react and react-dom @15 (npm i next react@15 react-dom@15 or npm i next@beta react react-dom)

[bntzio]

Yep, I just got it working, you need:

• react@16.0.0
• react-dom@16.0.0
• next@4.0.0-beta.2

[damusnet]

FYI, I just tried to update our app from Next.js 2.0 / React 15 to Next.js 4.0 / React 16, and except for a few warnings related to SSR / Client rehydration (on very edge cases, not critical at all), everything worked perfectly!

So, thank you to all contributors, this is amazing!

[timneutkens]

@damusnet great to hear ❤️ Closing this ticket 👍

[brendonco]

@timneutkens Have you tried in IE11?
