Our CI build has been incredibly flaky across all three of our current CIs:
* Appveyor: Chromium + Windows
* Travis: Firefox + Linux, Chromium + Linux
* Cirrus: Chromium + Linux, Chromium + Mac
Legitimate issues and errors have been missed because it's expected that the CI is red and therefore it's not seen as an issue when a PR's build fails.
We should have a build that covers the full combo of browsers and operating systems but it's more important to have a consistent, reliable green build where failures are genuine. So this commit strips our CI back to Chromium on Linux on Travis, and nothing more. Once this is stable we will expand out into more operating systems and bring back Firefox, too.
Our logic around missing methods wasn't quite right; if there is no set of missing methods for a class it _is_ an error and we still need to report it, we don't want to `continue`.
See the large code comment in the diff for a full explanation but we can't rely on the functions being referentially equivalent so instead we test the behaviour in duplicate tests across the deprecated method and the new method.
This is expected as we now alias `emulateMedia` in `index.js` which isn't a file checked by DocLint. We alias there to avoid having the function overriden by the `asyncInstallHooks` code.
This commit updates doclint to know about methods that we expect it will find are missing and in that case just skip over them. We should only do this for methods where we plan to deprecate them or we have to define them in an odd way to work around some problem (and if that's the case long term we should fix that problem so we can define them as normal).

They fail because cookies in Firefox return a `sameSite` key which the tests don't expect.
This is a solution that at least gets the Travis Firefox build (hopefully!) green again. Longer term it'd be great to allow the assertion to change based on the browser, rather than skip these tests entirely.
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.

The recommended Dockerfile uses node:10-slim image as a base,
but the base image does not contain wget command anymore.
(About the reason, see https://github.com/nodejs/docker-node/issues/1185)
So fixed the problem.
* (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 makes it more clear that the callback receives an actual array of nodes instead of just a NodeList.

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.
