This CL migrates all the tests to TypeScript. The main benefits of this is that we start consuming our TypeScript definitions and therefore find errors in them. The act of migrating found some bugs in our definitions and now we can be sure to avoid them going forwards.
You'll notice the addition of some `TODO`s in the code; I didn't want this CL to get any bigger than it already is but I intend to follow those up once this lands. It's mostly figuring out how to extend the `expect` types with our `toBeGolden` helpers and some other slight confusions with types that the tests exposed.

Without the API-* dependencies pinned different versions may be
installed on local machines vs CI. One of the checks we do is to check
that the checked in docs matches what is generated on CI. Therefore we
need to ensure devs locally run the exact version that CI runs such that
they generate the same output. So in this case we pin to a particular
version of the dependencies.
As far as I can tell these became irrelevant as of v1.15 which added
`puppeteer.errors` and `puppeteer.devices [1]. This is a breaking change
but one that's easily mitigated. We've said that we don't consider
changes to our folder/file structure a breaking change, but we can't
really do that if we have these two top level files that we've
documented.

It was causing some infra issues when trying to migrate tests to
TypeScript (that's WIP in another branch that I'll have up soon). It's
unusual to have the entire src in TS except for the main file, which
then reaches into the compiled `lib` directory for the files it needs.
Much better is to move the entry point into TypeScript itself and update
the `main` entry in our `package.json` to point to the compiled output.
This also has the advantange of hooking up all the TS type defs that we
are shipping and will make that process easier too, along with making it
easier to port our tests to TypeScript.
`api.ts` is a list of all our modules which is used to install a helper
and by DocLint. It's not that useful for our dep graph because it
literally requires the majority of modules so it just clutters up the diagram.
These files will be used by both the web and node versions of Puppeteer.
Another name for this might be "core" but I don't want to cause
confusion with the puppeteer-core package that we publish at the moment.
`--max-depth` stopped the chart including our own modules. What we want
instead is the `do-not-follow` option to make it go to infinite depth in
our code but stop at the top level of a node module.
This is another step towards making Puppeteer agnostic of environment
and being able to run in Node or a browser.
The files in the `node` directory are ones that would only be needed in
the Node build - e.g. the code that downloads and launches a local
browser instance.
The long term vision here is to have three folders:
* node - Node only code
* web - Web only code
* common - code that is shared
But rather than do that in one PR I'm going to split it up to make it
easier to review and deal with.
The TypeScript definition erroneously made `options` required. We can
fix it by providing a default value, which means users calling the
function will be able to leave it blank without TS complaining.
Issues like this are a +1 to porting our tests to TypeScript in order to
catch these on our own test suite, so that's something we should look into.
* chore: create new Debug module
This debug module can be used in either Node or the browser. We'll use
the `debug` module in Node land, but fallback to a simple `console.log`
solution when in the browser in an attempt to keep our browser bundle
size down.
* Use our debug wrapper rather than Node's `debug`.
A lot of the helpers in `helpers.ts` are heavily bound to NodeJS and at
the moment we're trying to make the `Connection` class be able to run in
multiple environments. Its only remaining Node dependency was its
reliance on `helpers.ts`, which it only needed for `assert`.
This is a useful change also because `helpers.ts` is quite large and
full of functions that do different things; I think we can name them
better and move them into modules with a specific purpose rather than a
generic `"helpers"` dumping ground.
Once this change lands `Connection` should be usable in the browser.
Fix child process killing when the parent process SIGINTs.
If you `ctrl + c` the Puppeteer parent process, we would sometimes not properly handle killing of the child processes. This would then leave child processes behind, with running Chromium instances. This in turn could block Puppeteer from launching again and results in
cryptic errors.
Instead of using the generic `process.kill` with the process id (which for some reason is negative the pid, which I don't get), we can kill the child process directly by calling `proc.kill`.

This PR splits the logging for send and receive messages in to separate debug channels.
This way it is easier to filter and takes advantage of debug's automated coloring to make
it easier to visually parse on the command line
* chore: remove "Extracting..." log message
Fixes#5741.
* test: support extra Launcher options and skips
The extra Launcher options and skipping conditions enable
unit tests to be run more easily by third-parties, e.g.
browser vendors that are interested in Puppeteer support.
Extra Launcher options were previously removed as part of
switching away from the custom test harness.
* test: enable more tests for Firefox
* chore: move `index.js` into `src`
This is the first part of a series of pull requests that will slowly
make it possible to initialise Puppeteer for either a Node environment
or a web one. By creating the `initialisePuppeteer` function we can
inject dependencies in for the given version of Puppeteer (e.g. inject a
different debug library for Node vs the web).
This PR moves the initialisation into `src` and calls into it from the
root `index.js`.
This PR starts exploring the Page class and how to best document it. It explores how best to document events in the system, and I think pulling them out into an `enum` is the best solution here. It lets us end up with a page of docs that explicitly lists all the events the page class can ever emit.
* chore: ensure new-docs are up to date
This adds a Travis check that if we re-generate the docs we get the
exact output (by checking if the Git tree is dirty).
We do the dirty check by using `git status --porcelain`, seeing how many
lines that outputs, and using that as the exit code (taking only the
first 255 lines to avoid invalid exit codes). `--porcelain` makes the
output be empty if the repo is not dirty in anyway which translates into
an exit code of 0.
We can't use `git diff-index --quiet HEAD` as it exits with 0 if there are
untracked files in the repo but we want that to cause a failure.
Just one was used externally and I wrapped that up in a method. I think
it's a useful method to provide (I can imagine wanting to know if JS is
enabled on a page) so I think there's no harm here (I'd rather that then
have JSHandle reach into a private variable).
