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.
This PR aims to vastly improve our TS types and how we ship them.
Our previous attempt at shipping TypeScript was unfortunately flawed for
many reasons when compared to the @types/puppeteer package:
* It only worked if you needed the default export. If you wanted to
import a type that Puppeteer uses, you'd have to do `import type X
from 'puppeteer/lib/...'`. This is not something we want to encourage
because that means our internal file structure becomes almost public
API.
* It gave absolutely no help to CommonJS users in JS files because it
would warn people they needed to do `const pptr =
require('puppeteer').default, which is not correct.
* I found a bug in the `evaluate` types which mean't you couldn't
override the types to provide more info, and TS would insist the types
were all `unknown`.
The goal of this PR is to support:
1. In a `ts` file, `import puppeteer from 'puppeteer'`
1. In a `ts` file, `import type {ElementHandle} from 'puppeteer'`
1. In a `ts` file, referencing a type as `puppeteer.ElementHandle`
1. In a `ts` file, you can get good type inference when running
`foo.evaluate(x => x.clientHeight)`.
1. In a `js` file using CJS, you can do `const puppeteer =
require('puppeteer')` and get good type help from VSCode.
To test this I created a new empty repository with two test files in,
one `.ts` file with this in:
https://gist.github.com/jackfranklin/22ba2f390f97c7312cd70025a2096fc8,
and a `js` file with this in:
https://gist.github.com/jackfranklin/06bed136fdb22419cb7a8a9a4d4ef32f.
These files included enough code to check that the types were behaving
as I expected.
The fix for our types was to make use of API Extractor, which we already
use for our docs, to "rollup" all the disparate type files that TS
generates into one large `types.d.ts` which contains all the various
types that we define, such as:
```ts
export declare class ElementHandle {...}
export type EvaluateFn ...
```
If we then update our `package.json` `types` field to point to that file
in `lib/types.d.ts`, this then allows a developer to write:
```
import type {ElementHandle} from 'puppeteer'
```
And get the correct type definitions. However, what the `types.d.ts`
file doesn't do out of the box is declare the default export, so
importing Puppeteer's default export to call a method such as `launch`
on it will get you an error.
That's where the `script/add-default-export-to-types.ts` comes in. It
appends the following to the auto-generated `types.d.ts` file:
```ts
declare const puppeteer: PuppeteerNode;
export = puppeteer;
```
This tells TypeScript what the default export is, and by using the
`export =` syntax, we make sure TS understands both in a TS ESM
environment and in a JS CJS environment.
Now the `build` step, which is run by GitHub Actions when we release,
will generate the `.d.ts` file and then extend it with the default
export code.
To ensure that I was generating a valid package, I created a new
repository locally with the two code samples linked in Gists above. I
then ran:
```
npm init -y
npm install --save-dev typescript
npx tsc --init
```
Which gives me a base to test from. In Puppeteer, I ran `npm pack`,
which packs the module into a tar that's almost identical to what would
be published, so I can be confident that the .d.ts files in there are
what would be published.
I then installed it:
```
npm install --save-dev ../../puppeteer/puppeteer-7.0.1-post.tgz
```
And then reloaded VSCode in my dummy project. By deliberately making
typos and hovering over the code, I could confirm that all the goals
listed above were met, and this seems like a vast improvement on our
types.
* chore: run unit tests on node 10.15
We saw in https://github.com/puppeteer/puppeteer/issues/6548 that the
`fs.promises` module was experimental in Node <10.17 and as such we
introduced issues for users on 10.15.
Until we can drop Node v10 (it's EOL is 30-04-20201
https://github.com/nodejs/Release#release-schedule) we should run our
tests on an old Node 10 to avoid regressing in this area.
* chore: helper for importing fs safely
This PR updates the socket transport code to swap between a Node web
socket transport or a web one based on the `isNode` environment. It also
adds unit tests to the browser tests that show we can connect in a
browser.
* chore(agnostification): common/helper.ts
The `readProtocolStream` method uses `fs` only if you want to write to a
file. So we gate at the start of the function and ensure that if we got
given a path we are not in a Node environment.
The `Puppeteer` class had two concerns:
* connect to an existing browser
* launch a new browser
The first of those concerns is needed in all environments, but the
second is only needed in Node.
https://github.com/puppeteer/puppeteer/pull/6484 landing enabled us to
pull the `Puppeteer` class apart into two:
1. `Puppeteer` which hosts the behaviour for connecting to existing
browsers.
2. `PuppeteerNode`, which extends `Puppeteer` and also adds the ability
to launch a new browser.
This is a non-breaking change, because Node users will still get an
instance of a class with all the methods they expect, but it'll be a
`PuppeteerNode` rather than `Puppeteer`. I don't expect this to cause
people any issues.
We also now have new files that are effectively the entry points for
Puppeteer:
* `node.ts`: the main entry point for Puppeteer on Node.
* `web.ts`: the main entry point for Puppeteer on the web.
* `node-puppeteer-core.ts`: for those using puppeteer-core (which only
exists in Node, not on the web).
The `Launcher` class was serving two purposes:
1. Launch browsers
2. Connect to browsers
Number 1) only needs to be done in Node land, but 2) is agnostic; in a
browser version of Puppeteer we'll need the ability to connect over a
websocket to send commands back and forth.
As part of the agnostification work we needed to split the `Launcher` up
so that the connection part can be made agnostic. Additionally, I
removed dependencies on `https`, `http` and `URL` from Node, instead
leaning on fetch (via `node-fetch` if in Node land) and the browser
`URL` API (which was added to Node in Node 10).
* chore(agnostify): Create Node and Web initializer.
This PR splits `initialize.ts` into two files, one for web, and one for
Node. The Node initializer requires much more information as it needs to
know which browser(s) to download and where to store them, whereas the
web one does not.
A future PR that I'm working on will tidy up `src/common/Puppeteer.ts`
(as it contains a lot of Node specific logic around downloading and
installing browsers), but this change enables us to stop the browser
bundle attempting to use the `pkg-dir` dependency, which wouldn't work
within a browser, as well as keeping the size of the PRs down and
avoiding one mammoth PR.
This commit adds a new built-in handler for querying by accessible name and role (#6307).
Support for waitForSelector will be added in a follow-up commit.
In `src/common` we now use `fs.promises.X` which we can dynamically
`import`. In a browser environment this code will never run because it's
gated on `isNode` (in a future PR we will add tree-shaking to the bundle
step such that this code is eliminated). By using `import`, we ensure
TypeScript still can track types and give good type information.
In `src/node` we continue to use `util.promisify` but that's not a
concern as that code explicitly is never run in the browser.
This commit changes the internal representation of query handlers to contain Puppeteer-level code instead of page functions.
The interface `CustomQueryHandler` is introduced for user-defined query handlers. When a `CustomQueryHandler` is registered using `registerCustomQueryHandler` a corresponding Puppeteer-level handler is created through `makeQueryHandler` by wrapping the page functions as appropriate.
The internal query handlers (defined by the interface `QueryHandler`) contain two new functions: `waitFor` and `queryAllArray`.
- `waitFor` allows page-based handlers to make use of the `WaitTask`-backed implementation in `DOMWorld`, whereas purely Puppeteer-based handlers can define an alternative approach instead.
- `queryAllArray` is similar to `queryAll` but with a slightly different interface; it returns a `JSHandle` to an array with the results as opposed to an array of `ElementHandle`. It is used by `$$eval`.
After this change, we can introduce built-in query handlers that are not executed in the page context (#6307).
The logic for waitForXPath and waitForSelector is currently very tightly coupled. This commit tries to untangle that relationship. This is the first step towards introducing built-in query handlers that are not executed in the page context (#6307).
Debug message clarifying the problem like `Issue 1060080: Event Network.loadingFinished is not sent when a frame is loaded from another domain`: https://bugs.chromium.org/p/chromium/issues/detail?id=1060080).
It can help users to identify problem with OOPIF easier without digging into the CDP protocol implementation like in the bug `1060080` mentioned above.
To reproduce:
1. Run `DEBUG="puppeteer:frame" NODE_PATH=../ node examples/oopif.js`.
2. Verify the output contains the debug message:
`
puppeteer:frame The frame '...' moved to another session. Out-of-proccess
iframes (OOPIF) are not supported by Puppeteer yet.
