This PR works around the upstream bug crbug.com/1325782. Previously Puppeteer relied on the presence of the loaderId to determine the kind of navigation and expected events. It does not look like there is a reason to do so: instead, we could see what events we get and proceed accordingly.

When defining a chunk size for <CDPSession>.send('IO.read', { handle, size }), the CDPSession will occasionally indicate that it has reached the end of file without sending a full pdf. This is documented by the associated issue.
This behavior is not reproducible when leaving out the size parameter. Since the size parameter is not required on the CDPSession side and is merely a suggestion on the stream side, we can safely leave it out.

If an iframe has a border, it has to be added to the offsets
too. We can work around it by using the content box coordinates
for the offsets. That should also prevent discrepancies if the
iframe has a padding set.
The doc for boundingBox says that it should return the boundingBox
relative to the main frame, therefore, this fix would make the
actual implementation correspond to the documentation. boxModel
documentation does not have this note but I think it'd make sense
to have it match the behaviour of the boundingBox API.
So it appears that all bindings are added to the secondary world and all
evaluations are also running there. ElementHandle.evaluate is returning
handles from the main world though. Therefore, we need to be careful
and adopt handles to the right context before doing waitForSelector

This updates the regular expression used to parse aria attribute
selectors so that single quotes may be used as an alternative to double
quotes, e.g. `aria/Single button[role='button']`.

This pull request to adds better support for OOP iframes (see #2548)
The current problem with OOP iframes is that they are moved to a different target. Because of this, the previous versions of Puppeteer pretty much ignored them.
This change extends the FrameManager to already take OOP iframes into account and hides the fact that those frames are actually in different targets.
Further work needs to be done to also make the NetworkManager aware of these and to make sure that settings like emulations etc. are also properly passed down to the new targets.
In some situations, Puppeteer is left in an invalid state because protocol errors that could have been handled by the user where just hidden from them. This patch removes some of these cases and also makes sure that unhandled promise rejections lead to a test failure in mocha.
Enable developers to handle 'Invalid header' errors instead of hiding them to make sure they can address them properly.

Puppeteer already allows creating a new CDP session
via target.createCDPSession but there is no way
to get access to any existing session to send
some additional commands.
Until now, the click would be always sent to the middle
point of the target element. With this change, one can define
offsets relative to the border box of the elements and click
different areas of an element.
Up to now, only strings starting with '//' are considered as to XPath selectors. Unfortunately, this is too restricting. This fix allows valid XPath selectors starting with: '/', './', and even '(//*[1])'
The values of these constant variables are always the exact same when the `parseAriaSelector()` function is called, so these can be moved out of the function.

With this change,`request.respond`, `request.abort`, and `request.continue` can accept an optional `priority` to activate Cooperative Intercept Mode. In Cooperative Mode, all intercept handlers are guaranteed to run and all async handlers are awaited. The interception is resolved to the highest-priority resolution. See _Cooperative Intercept Mode and Legacy Intercept Mode_ in `docs/api.md` for details.
This patch removes the redundant `await` from the block while fetching the target. The value in the map is a `Target` instance, which itself is not an async resource.
This commit adds drag-and-drop support, leveraging new additions to the CDP Input domain (Input.setInterceptDrags, Input.dispatchDragEvent, and Input.dragIntercepted).

This commit updates the JSHandle class to take a generic representing
the underlying object that it's wrapping. We can then define
`ElementHandle` as a class that extends `JSHandle<Element>` and begin
to get better type inference.
Prior to this commit the following code would have `d` set to `any`:
```
const div: page.$<HTMLDivElement>('div')
const text = await div.evaluate(d => d.innerText)
```
You could work around this in two ways:
```
const text = await div.evaluate<(d: HTMLDivElement) => string>(d => d.innerText)
const text = await div.evaluate((d: HTMLDivElement) => d.innerText)
```
But both of these have two issues:
1. Requires the user to type extra information.
2. There's no type checking: in the code above I could type `d` as
`number` and TS would be happy.
With the change here to `evaluate` the user can now type the original
code:
```
const div: page.$<HTMLDivElement>('div')
const text = await div.evaluate(d => d.innerText)
```
And TypeScript will know that `d` is an `HTMLDivElement`.
This change brings us inline with the approach that @types/puppeteer
takes. If we land this and it works, we can do the same with
`evaluateHandle` to hopefully make a similar improvement there.
BREAKING: because this changes the types, which were previously `any`,
this is technically a breaking change as users using TS could start
getting errors after this change is released.
This PR updates some code to remove constant ESLint warnings. It also
upgrades those warnings to errors - so that they have to be resolved
as part of the PR, rather than landing as a warning and causing noise.
Fixes#7229.
We're seeing odd failures with Prettier on some CI branches; my hunch is that they are installing different versions of the package and therefore getting formatting conflicts. This PR updates them all and pins them to specific versions - something we should probably consider generally, or remove our `package-lock.json` from the gitignore.
The `Page#click` method relies on `Mouse#click` for execution. `Mouse#click` triggers the `move`, `down`, and `up` methods in parallel waiting for all of them to finish, when they should be called sequentially instead.

* fix: make `$` and `$$` selectors generic
This means, much like TS's in built `querySelector` type, you can now do:
```ts
const listItems = page.$$<HTMLLIElement>('ul li');
```
And/or:
```ts
const h2 = page.$<HTMLHeadingElement>('h2');
```
And the return value will be of type `ElementHandle<T>|null`, where `T`
is the type you provided. By default `T` is an `Element`, so you don't
have to provide this if you don't care as a consumer about the exact
type you get back.
* chore: fix test assertions
This PR fixes the fact that currently if you have:
```ts
page.on('request', request => {
})
```
Then `request` will be typed as `any`. We can fix this by defining an
interface of event name => callback argument type, and looking that up
when you call `page.on`.
Also includes a drive-by fix to ensure we convert response headers to
strings, and updates the types accordingly.
We can use the new `Lowercase` util in TS4 to avoid duplicating the type
and instead lowercase it.
Note we still need to do the work so callbacks are typed correctly:
```ts
page.on('request', request => {
})
```
Right now `request` is `any`, whereas it should be a
`puppeteer.HTTPRequest`. You can manually set the type for now, and I
will work on adding types for events so that this is done automatically
by the compiler in a future release.
Fixes#6854.
This commit tidies up the quite confusing state of all the various types
required to launch a browser. As we saw when upgrading DevTools
(https://source.chromium.org/chromium/chromium/src/+/master:third_party/devtools-frontend/src/test/conductor/hooks.ts;l=77),
we had to define our launch options variable like so:
```ts
const opts: puppeteer.LaunchOptions & puppeteer.ChromeArgOptions & puppeteer.BrowserOptions = {
...
};
```
This commit fixes that by introducing `AllNodeLaunchOptions`, which is
defined as the intersection of all the above types.
Additionally, the types defined as `ChromeArgOptions` are actually used
for launching both Chrome and Firefox, so I have renamed them to
`BrowserArgOptions`, and therefore this change is breaking because
anyone using `ChromeArgOptions` in their types will need to switch.
BREAKING CHANGE: renamed type `ChromeArgOptions` to `BrowserLaunchArgumentOptions`
BREAKING CHANGE: renamed type `BrowserOptions` to `BrowserConnectOptions`
Also includes drive-by when I subbed `@default` (not valid) to
`@defaultValue` (valid!) in a few places and exposed types from
`Coverage.ts` so they get exposed too.
Fixes 6876.
During the migration to TS we changed `jsonValue` so it returned
`<Record<string, unknown>>`. This is only true if all the JSON values it
returns are objects; but it could return an array, a string, a number,
etc. Therefore we make the type generic, setting the default to
`unknown`, so the user has control over the type.
* fix: wider compat TS types and CI checks to ensure correct type defs
This PR improves our TS types further to make sure they are usable in a
TS environment where ES Modules are the target output. Our use of
`export =` is problematic this environment as TypeScript does not allow
`export =` to be used and it errors.
The fix for the type issues to avoid `export =` is to instead define the
functions that you gain access to when you import Puppeteer as top level
functions in our `types.d.ts` file. We can do this by declaring them
explicitly in `src/node.ts`. These are then rolled into `lib/types.d.ts`
at build time. The downside to this is that we have to keep those
declarations in sync with the Puppeteer API; should we add a new method
to the `Puppeteer` class, we must add it to the `nodes.ts` declarations.
However, this could easily be automated by a small script that walks the
AST and generates these. I will do that in a follow-up PR, but I
consider this low risk given how rarely the very top level API of
Puppeteer changes. The nice thing about this approach is we no longer
need our script that hacks on changes to `lib/types.d.ts`.
To avoid yet more releases to fix issues in one particular TS
environment, this PR also includes a suite of example setups that we
test on each CI run. Each sample folder contains `good.ts`, which should
have no TS errors, and `bad.ts`, which should have some errors. The test
first packs Puppeteer into a tar, and then installs it from that tar
into each project. This should replicate how the published package
behaves when it is installed. We then check that we get no errors on
`good.ts`, and the expected errors on `bad.ts`.
We have a variety of test projects that cover both TS and JS source
code, and CJS and ESM imports and outputs.
