In this example, we can:
- `QueryRenderer` SSR
- caching the data
- use the feature of `react-relay-network-modern` which is the powerful tool for `relay-modern`
I copy the example `with-relay-modern`, but I just modified the code. Some detail are not modified.
If you think this example is needed, I will fix those. Otherwise, close this **PR** to let me know this example is not needed.
- The with-firebase-auth example won't run unless a database with proper rules is created first.
- Add a small error callback to addDbListener to help with debugging if someone's database connection doesn't work.
On the server `props.initialMobxState` received by the `constructor` is a fully functioning mobx store that was instantiated by `getInitialProps()` only a few ticks earlier.
Thus, creating a new instance is unneccessary.
In the browser, however, `props.initialMobxState` is a hydrated plain object and thus the store needs to be initialized.
Current with-ant-design-less example has some problems.
- Upgrade next7, console found a 404 error.
> After upgrade next7, .next folder didn't find /static/style.css and there is /static/css/style.chunk.css.
- The /_next/static/style.css link don't need be placed in the <Head> tag. The style.chunk.css file will be add in the head tag automatically after build.
- The project with more pages include _app.js, _document.js...the antd-custom.less will not work well.
> The solution is use `modifyVars` of `lessLoaderOptions`. It work well in my project~
Instead of bundling `postcss-cli` we can now make use of `@zeit/with-css`.
This also means we can get rid of the `<style>` import and concurrent build step for css. 🎉
- use `enhanceApp` so that styled-components used in _app.js are server rendered
- call parent getInitialProps, fixes#5629
- return `styles`, making the render() method obsolete.

I spent far too much time fiddling with this example project before realizing it contained a bug in the store initialization logic and it was a bit more complex than it needed to be.
* The custom server was not needed
* The store-initialization did effectively the same thing twice for no reason
* And wrapping MyApp component in a HOC was wholly unnecessary indirection
My changes are split into four discrete commits for clarity.
* added example for using typings-for-css-modules-loader
* Update examples/with-typings-for-css-modules/README.md
* Update examples/with-typings-for-css-modules/README.md
* Update examples/with-typings-for-css-modules/next.config.js
- Looks like no other example provides a link to a hosted demo
- There is the "Deploy to now" badge, so it can be deployed on demand when needed
- The link is broken anyway
- Probably any example hosted by an individual contributor sooner or later will be cleaned up, doesn't feel like a reliable way to provide a live demo
package accept returns false if can't find language in offered list of languages, then later on
bool is attempted to be split, and app crashes in prod & dev
Docker Multistage
* Remove `devDependencies` from `./node_modules`
in `builder` for faster copy on `base` init
* Added `isomorphic-unfetch` to show it not
being copied over to `base`.
* `isomorphic-fetch` will still show from `next`
I successfully deployed this example with `now` and `now --public` (I am on premium plan).
Did this before deploy
```sh
$ cp Dockerfile.multistage Dockerfile
```
The mobx-state-tree examples (with and without typescript) pre-dated the next _app class and needed to be updated to use _app for persisting state across client-side navigation transitions. Also removed unneeded custom server class to better keep with the "show one feature per example" style of the next examples folder
Fixes#5352 . This updates the example updating react-i18next to v8.0.6, replacing the `translate` HOC to `withNamespaces` and `I18n` to `NamespacesConsumer`.
There is one thing that I am not sure if is correct or not so I need some guidance. You gotta wrap the page with the `withI18next` HOC so it will extend the `getInitialProps` of the page with this:
```
Extended.getInitialProps = async (ctx) => {
const composedInitialProps = ComposedComponent.getInitialProps
? await ComposedComponent.getInitialProps(ctx)
: {}
const i18nInitialProps = ctx.req
? i18n.getInitialProps(ctx.req, namespaces)
: {}
return {
...composedInitialProps,
...i18nInitialProps
}
}
```
The problem lies in `i18n.getInitialProps` that has this code:
```
i18n.getInitialProps = (req, namespaces) => {
if (!namespaces) namespaces = i18n.options.defaultNS
if (typeof namespaces === 'string') namespaces = [namespaces]
req.i18n.toJSON = () => null // do not serialize i18next instance and send to client
const initialI18nStore = {}
req.i18n.languages.forEach((l) => {
initialI18nStore[l] = {}
namespaces.forEach((ns) => {
initialI18nStore[l][ns] = (req.i18n.services.resourceStore.data[l] || {})[ns] || {}
})
})
return {
i18n: req.i18n, // use the instance on req - fixed language on request (avoid issues in race conditions with lngs of different users)
initialI18nStore,
initialLanguage: req.i18n.language
}
}
```
In my understanding, among other things, it gets the `i18n` object from the request (included by the `server.js`) and uses the data to create `initialI18nStore` and `initialLanguage`, and then return these two objects plus the `i18n` object itself. If you add the `i18n` object on the return, then there will be a crash on the client-side render of the page:
```TypeError: Cannot read property 'ready' of null```
I don't know why, but returning it breaks `NamespacesConsumer` component from `react-i18next` (the state becomes null). So I commented this line and the provider on `_app.js` is getting the `i18n` instance from the `i18n.js` file (the same as `server.js`). I don't know if this would be an issue so I would like help to debug this.
Regarding a question about having different global layouts via `_app.js` usage, it came up that we could use a static property in the page that needed a different one(Thanks @timneutkens )
Link to the Spectrum post: https://spectrum.chat/?t=af6ca794-5420-4780-abd8-96f085a19e09
This PR adds an example called `with-dynamic-app-layout`, that showcases that use case in the simplest way I could think of.
Let me know if there's changes or improvements to be made. 🎉

Since version 2.1, react-apollo is exposing some new components that use the function-as-child (or render-prop) pattern to let you connect apollo-client magic with your components. See the blog article: [New in React Apollo 2.1](https://www.apollographql.com/docs/react/react-apollo-migration.html)
If I'm not mistaken, it's generally agreed that this pattern is (where it works) superior to the HOC pattern, for reasons that are best explained here: https://cdb.reacttraining.com/use-a-render-prop-50de598f11ce
So I updated the with-apollo example to use the new API, and IMO this code is much simpler and natural to read and understand, especially if you are not already familiar with Apollo's HOC APIs.
I broke up my changes into separate commits, for easier review. Commits with "Refactor" in the message accomplish the goal of switching to the new APIs while minimizing line-by-line differences (select "Hide whitespace changes" under "Diff settings"). Commits with "Clean up" in the message follow up the refactoring with trivial things like reorganizing code sections, renaming variables, etc.
For the components doing mutations, I chose not to use the `Mutation` component, since that doesn't really make sense to me; a mutation is something that happens at a point in time, so it's not meaningful to represent a mutation in the markup, which exists for a period of time. All that component does is expose a `mutate` function for a single specified mutation, and `result` data for a single firing of the mutation (which we don't need anyways; apollo handles updating the local data with the result). To me it seems simpler and more flexible to just get the apollo client via `ApolloConsumer` and call `.mutate()` on it.
In case anyone is interested, here's what my version of `PostUpvoter` using the `Mutation` component looked like:
<details>
```jsx
import React from 'react'
import { Mutation } from 'react-apollo'
import { gql } from 'apollo-boost'
export default function PostUpvoter ({ votes, id }) {
return (
<Mutation mutation={upvotePost}>
{mutate => (
<button onClick={() => upvote(id, votes + 1, mutate)}>
{votes}
<style jsx>{`
button {
background-color: transparent;
border: 1px solid #e4e4e4;
color: #000;
}
button:active {
background-color: transparent;
}
button:before {
align-self: center;
border-color: transparent transparent #000000 transparent;
border-style: solid;
border-width: 0 4px 6px 4px;
content: '';
height: 0;
margin-right: 5px;
width: 0;
}
`}</style>
</button>
)}
</Mutation>
)
}
const upvotePost = gql`
mutation updatePost($id: ID!, $votes: Int) {
updatePost(id: $id, votes: $votes) {
id
__typename
votes
}
}
`
function upvote (id, votes, mutate) {
mutate({
variables: { id, votes },
optimisticResponse: {
__typename: 'Mutation',
updatePost: {
__typename: 'Post',
id,
votes
}
}
})
}
```
</details>

I'm happy with where things are at here, but I'm more than happy to address any comments, concerns, ideas for improvent!
Thanks!
This fixes https://github.com/zeit/next.js/issues/5260 by making sure that `index.js` has `getInitialProps` defined on the page exported component, not the child component.
When fixing that, I uncovered an issue where the server side rendered HTML did not match the clientside HTML, so I reworked _app.js to use the `i18nextprovider` component which has props to hydrate the initial data (for SSR), and makes sure the correct i18n instance is passed to all child components through context.

* Update package.json
Acording the last commit please, test this example , will be work .
Though it sounds like some folks do run getDataFromTree() on the client in order to avoid loading states, it's non-standard usage and potentially confusing. Also it's inconsistent with the other with-apollo examples.
The `with-flow` sample has some obsolete definitions which are unused by the sample code. Removing the un-imported declarations is the easiest approach.
Hi
In the current version of the example __custom-server-typescript__, types are never checked.
For instance, change the following line :
```
const dev = process.env.NODE_ENV !== 'production'
```
by :
```
const dev: number = process.env.NODE_ENV !== 'production'
```
then run `npm run dev`. The application launches perfectly, no error is thrown.
In dev environnement, it is preferable to check types all the time, to get immediate feedback. This PR activates type checking. Only when using nodemon, so no impact on production.
Now the above code will (rightfully) refuse to compile :
```
TSError: ⨯ Unable to compile TypeScript
server/index.ts (6,7): Type 'boolean' is not assignable to type 'number'
```
I simplified the example by removing `.eslintrc.js` and related packages, as well as `nodemon`.
I also added a description in the README to address the question by @kachkaev in the original pull request (#4163).
I think I accidentally deleted the branch my prior PR was based on before you had a chance to merge or decide whether to merge. In case I borked things with that delete, I'm resubmitting the PR and figuring you can close one or the other or both as desired.
Original notes:
Based on with-mobx-state-tree, but typescript instead of javascript
Aside from a few bits of typing and renaming .js files to .ts and .tsx, most of the the edits are to avoid warnings and errors when running the code through tslint (which can be done via the `npm run tslint` command in the example if desired).
To keep this example simple, the `<styled>` component (which is used by the javascript-based with-redux and with-mobx-state-tree examples for the clock component) is not used in this example. The `<styled>` library can of course be used with typescript but (I think) it requires a more complicated set of typescript and babel .configs than is needed for most other components and libraries, so I'm just directly styling the one formerly `<styled>` div to keep things simple and broadly applicable.

Closes#3638
Pulling out a few core points from the readme...
This example builds from /src into /dist, managing the different expectations of express.js (es5, commonjs) and next.js (es6) by using a pair of tsconfig.json files, both of which are run by `npm run build-ts` or any of the other npm targets.
Hot module reloading is largely but not completely wired up (nodemon is watching /dist but tsc isn't set up to watch /src and transpile changes in /src to /dist automatically (that's mainly because I wasn't sure how to start both nodemon and a pair of tsc watchers and be confident all would get shut down when the user killed dev mode). The readme suggests running `npm run build-ts` manually in another window to push changes from /src into /dev and on into the browser.
tslint is also wired up via `npm run tslint`
