* Compile pages to .next/static/<buildid>/pages/<page>
* Fix test
* Export class instead of using exports
* Use constant for static directory
* Add comment about what the middleware does
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The existing example currently does not work because of outdated usage patterns.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.
Fixes [this issue](https://github.com/zeit/next.js/issues/4747)
I don't know what is the reason why the process does not finish, because it can be reproduced in this repo in many environments (my local mac os and Netlify pipeline).
However, it fixes the problem and it's 100% safe.
* Add support for custom App and Component enhancers
* Add ctx.renderPage test
* Add tests for single enhancer function
* Cleanup renderPage options check
* Cleanup
* Add comment about backwards compatibility for renderPage
* Add more test cases
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 🎉
There are occasions where it is useful to have `target='_blank'` on hyperlinks within your own app. (For example, if your app is being loaded in an iframe and you'd like for the links to break out in to new windows.)
With this PR, the `onClick` logic in Link now checks for an external target on the nested <a/> tag, and will fall back to the default behavior if it's present, similar to the logic for shift-/cmd-clicking the link.
## What's wrong
This problem is specific to errors that happen on the client _after_ the initial mounting of the component. (The router has special logic to handle exceptions thrown in `getInitialProps` during a client-side navigation, and I've confirmed this logic is correct.)
Specifically, if the page is mounted, and you raise an exception on the page, the exception will cause the error page to be mounted without ever invoking `getInitialProps` on the new App/Error page pairing.
This has been illustrated with multiple repros in #4574.
## Why is it broken
This regression was introduced two months ago in #4156, where the invocation of `getInitialProps` was removed from the app's top-level error handler. Specifically, [this line](https://github.com/zeit/next.js/pull/4156/files#diff-895656aeaccff5d7c0f56a113ede9662L147) was removed and [replaced by a comment](https://github.com/zeit/next.js/pull/4156/files#diff-895656aeaccff5d7c0f56a113ede9662R167) that says that "`App` will handle the calling of `getInitialProps`".
I believe the sentiment about "`App` will handle calling `getInitialProps`" is mistaken. In fact, it really doesn't make sense on its face, since it would require an instance lifecycle method of `App` (which is mounted immediately after the comment) to invoke the `static getInitialProps` method on the error page.
## How I fixed it
I've fixed this in a fork by restoring Lines 146 – 148 that were removed in #4156. I think this is the right fix, but Next.js's handling of `getInitialProps` could certainly be improved. (The code in [this conditional](86d01706a6/client/index.js (L173)) speaks to the unnecessary complexity around this.)
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.
Fixes#4713
I ran into this issue, when re-installing :
```
error upath@1.0.4: The engine "node" is incompatible with this module. Expected version ">=4 <=9".
error Found incompatible module
```
I used `yarn install --ignore-engines` as a workaround.
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;
}
```
When clicking a next/link with a hash (#something) multiple times, it wouldn't keep the scrolling behavior browsers have. This makes sure we correctly trigger it.
Fixes#4686
Adds tests for @zeit/next-typescript so that we don't regress on this again.
I've fixed an issue in the `next` CLI too which caused lingering processes when the process gets force killed, which is what we do in the test suite, so it kept running if there was no manual quit.
