I was surprised when I tried to spread a `Set` in TypeScript and the browser complained about `Set.slice()` not being defined. This is because TypeScript does not automatically enable support for iterators when targeting earlier ES versions, like we do in the browser, unless you use the `"downlevelIteration": true` compiler option. This injects some helpers into the necessary files for reading/spreading iterators, which can be stuffed behind an import statement with using the `"importHelpers": true` compiler option and include `tslib` in our dependencies. This is already a dependency of several of our packages, so it shouldn't cause any additional modules.
I'd really like to upgrade to Typescript 3 for its `unknown` type, but we need to upgrade to `jest@23` to support a recent version of `ts-jest@23`.
The [jest changelog](https://github.com/facebook/jest/blob/master/CHANGELOG.md) breaks down the breaking changes in 23.x, but I found it to be slightly incomplete so I've broken down the changes that actually caused breaks for us here, and addressed each in individual commits to make review a little easier:
- the `testURL` config default was changed from `about:blank` to `http://localhost`
- this cause some XHR requests powered by JSdom to start failing. It seems these requests just do nothing in master but start to fail when JSdom is initialized with an actual URL... I think we would ideally stop sending meaningless XHR requests in the tests, but it was a lot easier to just set the config to `about:blank` for now, and we can worry about cleanup later if necessary
- `expect(...).toThrow()` only passes if an actual error was thrown.
- In two places in the index pattern code we were throwing strings, which broke the assertions. Fortunately/Unfortunately the errors are not being consumed by anything, so I was able to wrap them in `new Error()` without causing any issues.
- snapshots of mock functions now include a `results` array, detailing the return values of the function
- React fragments are now serialized as `<React.Fragment>` instead of `<UNDEFINED>`
- undefined props in React components are now stripped from snapshots
- minor changes to the ordering of mocks, imports resolution, and before hooks caused the uiSettings API tests to start breaking, but I'm replacing them with totally new tests in #22694 so I just deleted them here
- mocks created with `jest.spyOn()` that are restored now have their `mock.calls` reset, so some of the kbn-pm tests stated failing. This was fixed by restoring them with `jest.restoreAllMocks()` rather than trying to do it before the assertions
This upgrades prettier to version 1.14.0. The main motivation is to gain support for the new TypeScript language features introduced in 2.9 and 3.0.
Prettier versions 1.13 and 1.14 also introduced some other JavaScript and TypeScript style improvements resulting in a few small line break and parenthesis changes.
The relevant release notes are:
* [Prettier 1.13.0 Release Notes](https://prettier.io/blog/2018/05/27/1.13.0.html)
* [Prettier 1.40.0 Release Notes](https://prettier.io/blog/2018/07/29/1.14.0.html)
This upgrades TypeScript to version 2.9.2. My main motivation is the support for generic type arguments in JSX elements and tagged templates (e.g. for `styled-components`).
Problems arising from breaking changes in the new TypeScript version have been mitigated by:
* setting the `keyofStringsOnly` option until impacted code has been
future-proofed
* Restricting some joi-related generics
See the [release notes](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-9.html) for details.
Some follow-up tasks should be:
* Update EUI to support the new `keyof` behaviour
* Update new platform TypeScript code to support new `keyof` behaviour
* Remove `keyofStringsOnly` setting
This PR upgrades RxJS to version 6 and switches to a fork of `stream-to-observable` which includes an updated version of `any-observable` that supports RxJS 6 until https://github.com/jamestalmage/stream-to-observable/pull/10 is merged. The primary change in this version of RxJS is the movement of stream operators from `Obersable.prototype` to the `rxjs/operators` module. Some of the operators, like `catch` and `do`, have been renamed (`catchError`, and `tap`). The Obsevable factories have also been moved from static methods on the `Observable` class to named exports of the root `rxjs` module. Some of those factories have also changed slightly, like `fromEvent` which now emits arrays if the event handler is called with multiple arguments.
```js
// import the Rx namespace to get the Observable factories
import * as Rx from 'rxjs';
// import the operators as named imports
import { map, tap, switchMap } from 'rxjs/operators';
```
In order to make the license that applies to each file as clear as possible, and to be consistent with elasticsearch, we are adding Apache 2.0 license headers to the top of each file.
Existence of this header is enforced by eslint and tslint and missing headers were automatically added in the last commit by running:
```
node scripts/eslint --fix && node scripts/tslint --fix
```
* [tslint/kbn-pm] apply autofixes
* [tslint/kbn-pm] whitelist all console.log calls for now
