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.
> Workspaces are a new way to setup your package architecture that’s available by default starting from Yarn 1.0. It allows you to setup multiple packages in such a way that you only need to run yarn install once to install all of them in a single pass.

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`
The original example fails to compile on my windows machine but updating bs-platform fixes that.
Depending on bs-next causes example to fail (package compiled with old incompatible version of bs-platform) so I have included it in a bindings directory where it can serve as an example of reason bindings.
Sources have been migrated to the latest reason-react.
Running the [with-jest](https://github.com/zeit/next.js/tree/canary/examples/with-jest) example results in the following error:
```log

Upgrading the dependencies (jest) to the latest version helps!

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
