This patch teaches `page.setContent` to await resources in
the new document.
**NOTE**: This patch changes behavior: currently, `page.setContent`
awaits the `"domcontentloaded"` event; with this patch, we can now await
other lifecycle events, and switched default to the `"load"` event.
The change is justified since current behavior made `page.setContent`
unusable for its main designated usecases, pushing our client
to use [dataURL workaround](https://github.com/GoogleChrome/puppeteer/issues/728#issuecomment-334301491).
Fixes#728
This adds `page.accessibility.snapshot()`. It serializes and returns the accessibility tree for the page. By default, uninteresting nodes are filtered out of the snapshot.

This upgrades us to TypeScript 3.1.1, which fixes some build failures. Annoyingly TypeScript does a better job of checking `process.stdio`, which exposes that the DefinitelyTyped definition for it is wrong. See https://github.com/DefinitelyTyped/DefinitelyTyped/issues/11587. I'll look into submitting a patch for that later.
This patch introduces API to manage frame navigations.
As a drive-by, the `response.frame()` method is added as a shortcut
for `response.request().frame()`.
Fixes#2918.
This patch:
- moves implementation of page.goto and page.waitForNavigation
into FrameManager. The defaultNavigationTimeout gets moved to
FrameManager as well.
- moves NavigatorWatcher into FrameManager to avoid circular dependency
References #2918
This patch unifies logic in response trackign in page.goto and
page.waitForNavigation.
As a drive-by, we now make sure that we return the right response
for the right frame. This will come handy for future frame navigation
API.

If referer is passed to the options object its value will be used as the referer instead of the value set by `Page.setExtraHTTPHeaders()`.
This is the correct way to set referer header: otherwise, the `referer` header will override all the document subrequests.
Fixes#3090.
I ran TypeScript against our code with `strictNullChecks` on. Most of the errors generated are noise, because TypeScript doesn't understand how our `assert` method works. But some were legitimate bugs. They are fixed in this patch.
This patch:
- merges `ElementHandle` into `ExecutionContext` (for simplicity; there's no good reason to have them in separate files).
- removes the necessity to pass handle factory when creating `ExecutionContext`
This makes it easier to create execution contexts out of payloads.
References #1215
It turned out that almost any usecase requires helper methods to access
DOM inside the ExecutionContext.
Instead of exposing execution contexts as-is, we should introduce
IsolatedWorld as a first-class citizen that will hold execution contexts
inside.
When an evaluation causes a navigation, for example:
```js
await page.evaluate(() => window.reload());
```
sometimes we process the ExecutionContextDestroyed event before the ack from the evaluate. When we do get the ack from the evaluate, we try to build a JSHandle for it, and try to find the execution by id. But it is gone, and we throw an error. This patch switches createJSHandle to accept an ExecutionContext instead of just an id.
This bug was making the test `should throw a nice error after a navigation` flaky.
In accordance with its declared type, `Map<string, Function>`.
Currently, it is used as a plain old JS object. The compiler marks this
usage as an error when `noImplicitAny: true`. This change switches to
use the appropriate Map methods `has/get/set`.
Fixes#3000
Unfortunately, disabling javascript in page prevents any microtasks
to be executed even from puppeteer-originating javascript. As a
result, the IntersectionObserver hack we use to conditionally
scroll into view doesn't work.
To workaround this, we start always scrolling before clicking if
page's javascript is disabled.
Fixes#2898
This patch:
- adds `worker.evaluate` and `worker.evaluateHandle` methods as a shortcut to their execution context equivalents.
- makes the error messages a bit nicer when interacting with a closed worker (as opposed to a closed page).
- moves the worker tests into their own spec file.
Since Node 10, `console.assert` no longer throws an AssertionError.
(This is generally good since it aligns Node.js with Browsers.)
This patch migrates all usages of `console.assert` in our codebase.
- All the `lib/` and testing code is migrated onto a handmade `assert`
function. This is to make Puppeteer transpilation / bundling easier.
- All the tooling is switched to use Node's `assert` module.
Fixes#2547.
Page subtargets (e.g. out-of-process iframes and others) sometimes
die before we send the 'detach' command.
This is harmless to us, but we shouldn't have an unhandled promise
rejection in this case.
Example crash: https://cirrus-ci.com/task/4884032470908928
This adds `page.workers()`, and two events `workercreated` and `workerdestroyed`. It also forwards logs from a worker into the page `console` event.
Only dedicated workers are supported for now, ServiceWorkers will probably work differently because they aren't necessarily associated with a single page.
Fixes#2350.
Today, `page.close()` method doesn't run page's beforeunload listeners.
This way users can be sure that `page.close()` actually closes the
page.
This patch adds an optional `runBeforeUnload` option to the
`page.close()` method that would run beforeunload listeners. Note:
running beforeunload handlers might cancel page closing.
Fixes#2386.
This uses the `/json/protocol` endpoint to generate type definitions for the protocol.
Currently it is lacking protocol events and commands, but I will add those later.
