Explains in details how the "with-universal-configuration" example works and rename it to "with-universal-configuration-build-time". Changing the example name makes the purpose of the example clear.
The "env-config.js" file introduce one more sample of variable usage that instantiates an immediate value of the local environment variable. This makes it even clearer how build-time variable configuration works. The "index.js" page makes explicit the use of these configured environment variables.
The universal configuration confusion happens when the value of the environment variable is used directly in the application causing an effect in server-side but not on the client side.
This example show how you can test Next.js apps with [react-testing-library](https://github.com/kentcdodds/react-testing-library).
This library encourages your applications to be more accessible and allows you to get your tests closer to using your components the way a user will, which allows your tests to give you more confidence that your application will work when a real user uses it. And also, is a replacement for enzyme.

This fixes the `with-jest-typescript` example to keep jest in sync with babel-jest (also updated to the latest of both). Having them resolve to different versions was resulting in weird errors.
When attempting to update the `transform` property in `jest.setup.js` to add babel-jest support to *.js/jsx files, it would throw:
> Plugin 0 specified in "node_modules/next/babel.js" provided an invalid property of "default" (While processing preset: "node_modules/next/babel.js")
Indirectly, this will fix https://github.com/zeit/next.js/issues/5917, once the author updates `jest.setup.js` to have:
```js
transform: {
'^.+\\.(js|tsx)?$': 'babel-jest',
},
```

* Update all dependencies and remove redundant ones from package.json. (60f9ee5)
* Fixes#5596 by adjusting nodemon scripts (d4b7d3a)
* Fixes `npm start` on windows by using `cross-env` (9555217)
* Move compiled server out from `.next`. Compiling other JS into `.next` seems incorrect. (79fce02,
9ce7086)
* Partly fixes#5753 by making sure typescript compiles with `es2017` as target, at least ensuring code is runnable on node 8. Previously it was compiled with `esnext`. (9176e92)

I tried improving the structure by keeping source in `src/app` and `src/server` and then building to `dist/server` and `dist/app` but I didn't really get it to work and made most configs more complicated. Moved the built server out from `.next` anyway.
The `initialNow` prop is used to avoid content mismatches when Universal/SSR apps render date values using components like `<FormattedRelative>`.
If this value is created in `render()`, then the server will generate it and then the client will also generate it during hydration / initial render, resulting in two different values and content mismatches like:
> Warning: Text content did not match. Server: "in 1,741,545 seconds" Client: "in 1,741,543 seconds"
If the value is instead generated in `getInitialProps`, then the client's initial rendering will match because it will use the same value sent down by the server.
There were several issues with the example [examples/with-firebase-hosting-and-typescript](https://github.com/zeit/next.js/tree/canary/examples/with-firebase-hosting-and-typescript)
* `npm run serve`
* Has no `pre` task that actually builds the app. Requires manual running of all build scripts.
* Will choke on windows because trying to set environment variables with `NODE_ENV=production`
* Outdated Typescript and Tslint
* Not being able to deploy because `firebase-tools` being of a deprecated version.
* Structure, which I understand is based on `firebase-tools` generation, is confising with `src/functions/src` being generally bad structuring.
I remedied this and also improved some other factors:
* Remove dependency `prettier` as it is unused (f4d6f54)
* Upgrade all dependencies (09a9193)
* Use upgraded firebase dependencies to deploy to node 8 environment (87e1e09, 7d8055b)
* Remove deprecated tslint rule `no-unused-variable` (9392162)
* Flattened filestructure in `src/functions` (097a25a)
* Use ES import when importing next (6c99adb)
* Fixed incorrect name and added somewhat to the description in package.json.
`with-firebase-hosting` → `with-firebase-hosting-and-typescript` (1ffa0b5)
* Fixed `serve` script by building before running, using [`cross-env`](https://www.npmjs.com/package/cross-env) to set environment variables and remove unecessary flag. (3a1e221, 422ccee, 8811e44)
* Add `.firebase` cache to `.gitignore` (4d7cbe4)
* Add `-C` (clean) flag when copying dependency files `copy-deps` (0826708)
* Use `strict: true` in the functions tsconfig (229b04f)
This was tested by running serve on windows and linx(WSL) and deploy on linux(WSL)

This is based on #5819 but correctly based from `canary`
Hello!
I was looking at the [`with-firebase-hosting`](/zeit/next.js/tree/canary/examples/with-firebase-hosting) example and was having some various issues running it:
* `npm run serve` will choke on windows because trying to set enviroment variables with `NODE_ENV=production`
* `npm run build-funcs` failing because of babeljs mismatches between `@babel/cli@^7.0.0-rc.1` and `next@^6.0.3`
* Not being able to deploy because `firebase-tools` being a deprecated version.
I remedied this and also improved some other factors:
* Use standard JSON formatting on `package.json` so that `npm install` doesn't cause changes on every run. (a83e930)
* Remove "prettier" as a devDependency as there is no use of it in the example and most other examples does not have it as a dependency. (6095663)
* Update all dependencies. The simple usecase in this example didn't really require any changes to the code. (ccde086)
* [`firebase-admin@6`](https://github.com/firebase/firebase-admin-node/releases/tag/v6.0.0)
* [`firebase-functions@2`](https://github.com/firebase/firebase-functions/releases/tag/v2.0.0)
* [`firebase-tools@4`](https://github.com/firebase/firebase-tools/releases/tag/v4.0.0)
* [`firebase-tools@5`](https://github.com/firebase/firebase-tools/releases/tag/v5.0.0)
* [`firebase-tools@6`](https://github.com/firebase/firebase-tools/releases/tag/v6.0.0)
* Make `npm run serve` runnable on windows using [`cross-env`](https://www.npmjs.com/package/cross-env). (b20dda7)
* Update `.gitignore` to ignore firebase cache (bf761b7)
* Remove `src/app/.babelrc` that seems to have been added as a previous bugfix but doesn't seem to do anything currently. (1b02045)
* Remove point from [`README.md`](https://github.com/zeit/next.js/blob/canary/examples/with-firebase-hosting/README.md) that was mentioning any `predeploy` hooks in `firebase.json` as they were removed in 4f4b7a1bce. (5636d9f)
* Use the possibility added by upgrading `firebase-tools` to [`>=4.0.0`](https://github.com/firebase/firebase-tools/releases/tag/v4.0.0) and `firebase-functions` to [`>=2.0.0`](https://github.com/firebase/firebase-functions/releases/tag/v2.0.0) to make the deployable functions use node 8 rather than node 6. Also make babel compile with node 8 as target for less polyfills etc. (c954cc2)
* Added comment to [`README.md`](https://github.com/zeit/next.js/blob/canary/examples/with-firebase-hosting/README.md) explaining how firebase deploys to node 8 and that babel will compile code for node 8. (d8b2e65, 91953dc)
This was tested to `serve` on windows, linux(WSL) and on mac. Deploy was tested on linux(WSL) and mac.

🔔 @jthegedus @timneutkens
Google seems to be deprecated the legacy realtime database and moving towards default use of Firestore, although it's still officially in beta. This PR migrates towards Firestore and the recommended loading methods for the Firebase 5.6.0 libraries. Note: the Firebase and Firebase-Admin dependencies should be updated to 5.6.0 and 6.3.0 respectively.
Hey @timneutkens I've updated this example a bit.
- Fixed `/asserts` spelling to `/assets`.
- Removed the `/assets/styles.less` as importing this caused the entire ant-design css sheet to be loaded, now only the React components imported will have their styles loaded via the babel plugin which was already configured. Resulted in dropping the CSS for this example from ~630kb to ~220kb.
- Removed `index.js` as it's not needed.
* Fix for locale.split is not a function.
Following from https://github.com/zeit/next.js/pull/5488
- Renamed languages to supportedLanguages
- Firstly, accept languages based on supportedLanguages
- And finally, accept a single language, if it returns false, the default of 'en' is used.
I looked at the navigator library, which is used by 'accept', this should be a more solid solution, since we can now know that `const locale` is always a string.
// Before (Sometimes returns an array as `const local`)
const locale = accept.language(languages) || 'en'
// After (Always returns a string)
const locale = accept.language(accept.languages(supportedLanguages)) || 'en';
* Update server.js
Update variable name.
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~
