I did not add or remove `^` near dependency versions in package.json files. However, I don't exclude that some changes can be made given that rc is more stable than beta.
Changes:
* Split `Header` component trough `_document.js` and `_app.js`
* Attached Router events with a way described in the [documentation](https://github.com/zeit/next.js#router-events) (though in the documentation is says it should be `Router.events.on` while I managed to get it working only by `Router.router.events.on` and I had to place it inside `componentDidMount`)
## Issue
Running [examples/with-custom-babel-config](https://github.com/zeit/next.js/tree/canary/examples/with-custom-babel-config) will result in the following error message:
```
./pages/index.js
Module build failed (from /some_path/next.js/dist/build/webpack/loaders/next-babel-loader.js):
Error: [BABEL] /some_path/next.js/examples/with-custom-babel-config/pages/index.js:
As of v7.0.0-beta.55, we've removed Babel's Stage presets.
Please consider reading our blog post on this decision at
https://babeljs.io/blog/2018/07/27/removing-babels-stage-presets
for more details. TL;DR is that it's more beneficial in the
long run to explicitly add which proposals to use.
...
```
## Explanation
Babel removed Babel's Stage presets on July 27, 2018.
More info: https://babeljs.io/blog/2018/07/27/removing-babels-stage-presets
## Solution
I've updated the example so ist just uses the babel plugin it actually needs.

Closes: #4772
Changes:
- Use css prop on the element to style it
- Add webpack + babelrc configuration to remove otherwise needed import boilerplate [according to glamor docs](https://github.com/threepointone/glamor/blob/master/docs/createElement.md)
Rationale: The killer feature of glamor that makes it so great is that it relieves you from naming classes/styles if you use the custom css prop. Together with the babel plugin you also don't need any extra import wherever the css prop is used.
All the real world uses I've seen of glamor has used the css props so I think the example should reflect this. As an example here is docs how to use glamor with gatsby (using the css prop):
https://www.gatsbyjs.org/docs/glamor/
Changes:
* moved the configuration from HOC to `_app.js`
* fixed the example, as `componentDidCatch` catches errors during rendering phase, but not within event handlers.
Changes:
* updated packages
* moved the content of `layout` to `_app.js` and created simple `Page` component
* replaced `import * as React` because it is not necessary to import everything
* moved `next.js.flow` to `flow-typed` as it is default directory for library definitions
* updated the gif
The existing example currently does not work because of outdated usage patterns. This PR seeks to update these patterns to the latest recommended best practice while bumping versions.
# Summary
- Bumped version numbers in `package.json`;
- Moved `<link />` tag from `pages/index.js` to `pages/_document.js` as is [recommended](https://github.com/zeit/next-plugins/tree/master/packages/next-css#usage);
- Replace individual css/font imports with import of minified CSS as is [recommended](https://react.semantic-ui.com/usage#semantic-ui-css-package);
- Removed prop (no longer used) from `<List />` element.
I’ve been experimenting with Next.js and Fastify and I made the following changes to the Fastify example based on what I found:
### Use Fastify’s plugin API
IMO putting Fastify’s listen call in a promise callback is an anti-pattern, b/c the Fastify plugin API is meant to solve the problem of async server bootstrapping.
[From Fastify’s Getting Started docs](https://www.fastify.io/docs/latest/Getting-Started/):
> Fastify provides a foundation that assists with the asynchronous bootstrapping of your application.
### Set reply.sent in handlers which return promises
[From Fastify’s Routes docs](https://www.fastify.io/docs/latest/Routes/#promise-resolution):
> If your handler is an `async` function or returns a promise, you should be aware of a special behaviour which is necessary to support the callback and promise control-flow. If the handler's promise is resolved with `undefined`, it will be ignored causing the request to hang and an *error* log to be emitted.
>
> 1. If you want to use `async/await` or promises but respond a value with `reply.send`:
> - **Don't** `return` any value.
> - **Don't** forget to call `reply.send`.
> 2. If you want to use `async/await` or promises:
> - **Don't** use `reply.send`.
> - **Don't** return `undefined`.
`app.render` returns a promise which contains undefined, so returning it in a Fastify handler will log an error. However, returning anything besides undefined will cause Fastify to try to write to the response which Next.js has already ended. The solution is to manually set the `reply.sent` flag to true when any Next.js rendering promise is fulfilled as an alternative to calling `reply.send`.
### Make Next.js handle 404 errors
This allows any route to throw a NotFound error and let Next.js handle the rendering of the 404 page.
### Make Next.js handle any route which starts with `_next` in dev
This prevents dev routes from being caught by user-defined routes.
As seen on `with-apollo-auth` there are some things that need to be addressed here too.
* #4554 remove useless `apolloState` from App props on `getDataFromTree`
* #4563 simplify `apolloState` prop
Let me know if further changes/fixes are needed.
Thank you 🎉
Updating to a more recent version of `@types/next` fixes an error I encountered while building a new app on top of the "with-typescript" example:
`Property `push` not found in SingletonRouter`
Additional context: https://github.com/DefinitelyTyped/DefinitelyTyped/issues/26665
To test, add a simple Router.push operation to the `pages/index.tsx`
```
import Router from 'next/router'
// ...
<span onClick={() => Router.push({ pathname: '/about' })}>TEST</span>
```
Apollo's getDataFromTree is supposed to be called during the server side rendering.
Being called in browser it fires an unnecessary fake render process and blocks components from rendering with loading=true.
Also there was a mistake in this code:
// `getDataFromTree` renders the component first, the client is passed off as a property.
// After that rendering is done using Next's normal rendering pipeline
this.apolloClient = props.apolloClient || initApollo(props.apolloState.data)
**Apollo** component is not rendered by getDataFromTree actually, it renders the **App** directly, thus props.apolloClient will always be undefined.
This example was discussed here: https://github.com/zeit/next.js/issues/387.
The purpose of the PR is to add the simplest possible integration with Storybook.
It leaves the default Storybook and also adds a custom component to show how it would be used in both the app and Storybook.
Update:
Tested with latest 👉 6.1.1
I had some trouble to get server side rendering with the AWSAppSyncClient working. I finally found a solution in https://github.com/awslabs/aws-mobile-appsync-sdk-js/issues/82 but it might be worth to share it here as well. Instead of adding a big code block to each file I'll just refer to this Pull Request.
______
In case you want to use the `AWSAppSyncClient` you just need to replace the `create()` function with this function:
```jsx
import AWSAppSyncClient from 'aws-appsync';
import { AUTH_TYPE } from 'aws-appsync/lib/link/auth-link';
function create(initialState) {
const client = new AWSAppSyncClient({
url: AWS_AppSync.graphqlEndpoint,
region: AWS_AppSync.region,
auth: {
type: AUTH_TYPE.API_KEY,
apiKey: AWS_AppSync.apiKey,
// Amazon Cognito Federated Identities using AWS Amplify
//credentials: () => Auth.currentCredentials(),
// Amazon Cognito user pools using AWS Amplify
// type: AUTH_TYPE.AMAZON_COGNITO_USER_POOLS,
// jwtToken: async () => (await Auth.currentSession()).getIdToken().getJwtToken(),
},
disableOffline: true,
}, {
cache: new InMemoryCache().restore(initialState || {}),
ssrMode: true
});
return client;
}
```
with-socket.io example was using a single index file and was managing connection in there. This would lead handling connection (disconnecting and reconnecting) in each added page.
I updated example with addition of `_app.js` and handled connection in there. This helped only subscribing to event in page and maintaining connection throughout example.
I have updated [examples/with-markdown](https://github.com/zeit/next.js/tree/canary/examples/with-markdown) in order to make it works with next 6 🎉

Hello!
I have updated `babel-plugin-module-resolver` to `^3.1.1` and moved it to `devDependencies` in [with-absolute-imports](https://github.com/zeit/next.js/tree/canary/examples/with-absolute-imports) example to make it work with Babel 7 :)

**Make amp example valid**
I'm using amp validator chrome plugin which shows that `meta charset=utf-8` is duplicated.
I assume that `Head` component adds `<meta charset="utf-8" class="next-head next-head">`
anyway.
And this line just duplicating it.

Hello! I ran into an issue using typescript and jest with next 6.0.0. I was able to work through fixing it and I wanted to share my solution back to next.js, by upgrading the with-jest-typescript example to next 6.0.0.
The steps I followed were:
1. `npx babel-upgrade --write` which added babel-core@^7.0.0-bridge.0 to allow jest's babel 6 to play nice with next's babel 7
2. Remove `ts-jest` and replace with `babel-jest` to use babel to transform the typescript code, as is done when the dev and production builds run
3. Update the babelrc to use commonjs modules in test mode to be compatible with jest
Also, I removed the `NODE_ENV=test` on the jest task, because jest sets the env to test anyways, and I'm on windows where this code is incorrect. The other option is to use `cross-env` but I felt it was simpler to just remove the environment override.
To my knowledge, this PR would help on the following issues:
#3663#4227#4531#4528#4239
Changes
* Update dependencies.
* Remove sending client prop to component on pages.
* Use withApollo correctly on components.
* Use `client.cache.reset()` instead of `prop.client.resetStore()`.
@adamsoffer @timneutkens
* with-firebase-hosting: update next.js 6, readme about customization
* now next.js 6 is on Babel 7, remove conflicting babel deps
* update Next Server/Cloud Function .babelrc config
* update other deps: Cloud Functions to 1.x.x etc
* rm install-deps script as it is no longer used on deployment (firebase does not upload node_modules)
* make scripts consistent in their wrapping of dirs with \" (escaped double quotes)
* with-firebase-hosting: pin next to "latest" version
* with-firebase-hosting: fix lint errors
Adds an example based off of @jthegedus work on firebase hosting, compatible with next v6 and using typescript in both the firebase functions and the next app.
Electron recommends to disable nodeIntegration in BrowserViews.
This PR follows this recommendation and updates the example accordingly.
Changes:
- disable nodeIntegration
- update dependencies
* Rename page component's class name: Counter => Index, Counter => Other
* Rename counter component class name: AddCount => Counter
* Add counter actions `decrement` and `reset` same as with-redux example
* Modify page link by NavigateTo attr in Page component
* Modify license MIT => ISC same as others in package.json
* Modify README
fixes#4390
* Installing only `babel-plugin-transform-decorators-legacy` didn't work
* It also needs to install `babel-plugin-transform-class-properties`
It's better that Counter behave not only `increment (add)` but also `decrement` or `reset`.
* Add decrement, reset handlers and rename add handler in `components/counter.js`
* Add increment, decrement, reset actions to `store.js`
* Rename page component class name: Counter => Index in `pages/index.js`
* Remove needless dispatch count event on getInitialProps in `pages/index.js`
* Format JSX to be readable in `pages/_app.js`
* Remove needless line from `components/examples.js`
* Remove needless spaces in `lib/with-redux-store.js`
