Rather than use our own custom expect library, we can use expect from npm [1], which has an API almost identical to the one Puppeteer has, but with more options, better diffing, and is used by many in the community as it's the default assertions library that comes with Jest.
It's also thoroughly documented [2].

This updates our `tsconfig.json` so it emits our JavaScript files as
well as type checking them. We compile into `./lib` which we then ship
in our npm package. The source code has moved from `./lib` into `./src`.
Because the `src/` directory is exclusively JS files, this change is a
no-op in terms of code functionality but is the first step towards being
able to replace `src/X.js` with `src/X.ts` in a way that allows us to
migrate incrementally.
The `lib` directory is gitignored, and the `src` directory is
npmignored. On `npm publish` we will now run `npm run tsc` in order to
generate the outputted code.
TypeScript seems to struggle to understand `Promise.all` when the items in the array return different types. If we were authoring in TS we could fix this with TS generics (`Promise.all<OurTypeHere>(...)`) but for now we can typecast the result. We'll fix this properly when we author in TS.
Continues the work to get up to TS 3.8 (latest release at time of writing).
This version of TS introduced built in definitions for web workers that include an `interface Worker` so TS gets confused when it sees us reference a `Worker`. I have renamed the imports to `PuppeteerWorker` as I couldn't figure out a way to tell TS to not load in the worker types; longer term we might consider renaming `Worker` to `PuppeteerWorker` (or an alternative) but that would be a breaking change that we don't need right now.
The other fix is similar; TypeScript doesn't differentiate between the built-in `WebSocket` type and the `ws` library. Renaming the import solves this too.
TS 3.5 got much stricter on writing changes to objects with varied types [1] so we have to do a bit of typecasting work to convince TS about the types of keys and values that we are setting.
Longer term we should think about a better data structure that avoids us having to jump through some hoops but for now I think this is a reasonable step to get us onto 3.5.
Same story regarding bindings on `window`: the easiest fix is to cast `window` to `any` for the code that adds to it. I'm sure we can come up with a more type-safe way of doing this in the future.

* (feat) Add option to fetch Firefox Nightly
Add Firefox support to BrowserFetcher and the install script.
By default, the latest Firefox Nightly is downloaded
directly from archive.mozilla.org (dmg, tar.bz2 and zip)
This also required changes that impact `puppeteer.launch()`
and `puppeteer.executablePath()`

* chore: update relevant Node.js versions from 8 to 10
* chore: remove node6 and node8 folders from puppeteer-firefox ci
* fix: loosen definition for proc.stdio
* fix: update typescript version used in npm run test-types
This changes the Chromium revision to r722234 (Chrome 80.0.3987.0),
since that's the most recent version in the Chromium 80 range for
which a download exists for all supported platforms.
https-proxy-agent requires agent-base, which currently monkey-patches the core `https` Node module, causing problems in unrelated code. The latest version of https-proxy-agent uses the latest version of agent-base which no longer does this monkey patching.
* fix: prepare jsHandle.uploadFile for CDP Page.handleFileChooser removal
https://chromium-review.googlesource.com/c/chromium/src/+/1935410
removes Page.handleFileChooser from the CDP.
* fix: improve binary file support
UTF-8-decoding the input file could fail for binary files, and so we
now read the raw file buffer and base64-encode it. To base64-decode it
within the page context, we use the Fetch API in combination with a
data URL. This requires knowing the proper MIME type for the input
file, which we now figure out using the new mime-types dependency.
* feat: Set which browser to launch via PUPPETEER_PRODUCT
This change introduces a PUPPETEER_PRODUCT environment
variable as a first step toward using Puppeteer with
many different browsers. Setting PUPPETEER_PRODUCT=firefox, for
example, enables Firefox-specific Launcher settings.
The state is also exposed as `puppeteer.product` in the API
to support adding other product-specific behaviour as needed.
The bulk of the change is a refactoring in Launcher
to decouple generic browser start-up from product-specific
configuration.
Respecting the puppeteer-core restriction for PUPPETEER_
environment variables, lazily instantiate the Launcher
based on a `product` Puppeteer.launch option, if available.
* test: Distinguish Juggler unit tests from Firefox
The funit script is renamed to fjunit (j for Juggler, which is
used only by the experimental puppeteer-firefox package.
In contrast, the funit script now refers to running Puppeteer
unit tests against the main puppeteer package with Firefox.
To do so with Firefox Nightly, run:
`BINARY=path/to/firefox npm run funit`
A number of changes in this patch make it easier to run
Puppeteer unit tests in Mozilla's CI.
Node.js v6 was end-of-life'd in April, 2019, with AWS Lambda prohibiting updaets to the Node.js v6 runtime since June 30, 2019.
This makes it quite safe for us to remove the Node 6 support from the repository.
This roll includes:
- https://crrev.com/681997 - Turn on default SiteInstance by default.
The SiteInstance by default was breaking "devtools: true" option, so
there's a new feature we disable now by default.
This keeps pressuring us towards OOPIF support since that's an
inevitable future.
* feat(chromium): roll Chromium to r665405
This roll includes:
- https://crrev.com/665226 - DevTools: make interception respect cross-process frame boundaries
This fixes page loading with dynamic OOPIFs - test is added.
Fix#4442
* fix lint
This roll includes:
- [inspector_protocol:8ec18cf](8ec18cf088) Support STRING16 in the template when converting CBOR map keys
to protocol::Value.
- [inspector_protocol:37518ac](37518ac421) fix parsing of the last ASCII character
This fixes protocol handling of UTF8 in both V8 and Chromium.
Fixes#4443.
