This patch converts lib/DevicesDescriptors from a devtools front-end
format into a puppeteer format.
This patch does this via introducing a scripts utils/fetch_devices.js
which grabs devices from upstream of DevTools Front-end and
converts them into puppeteer devices.

Currently, it's impossible to do screenshots in parallel.
This patch:
- makes all screenshot tasks sequential inside one browser
- starts activating target before taking screenshot
- adds a test to make sure it's possible to take screenshots across
tabs
- starts waiting for a proper page closing after each test. This might
finally solve the ECONNRESET issues in tests.
References #89
This patch:
- resolves pending callbacks in connection once it gets closed
- fixes one of Page.screenshot() tests to wait for all the screenshots
- starts handling ECONNRESET error in test server to avoid throwing with no
good reason
This patch introduces Page.waitForNavigation which allows to wait
for render-initiated navigation.
This patch also does a nice refactoring, replacing Navigator with NavigatorWatcher which
is not a part of a page state.
References #89
This patch re-introduces the DEBUG module to expose some of
the puppeteer's internals.
Currently, only the protocol message communication is exposed under
the 'puppeteer:protocol' namespace.
This patch:
- renames Page.printToPDF into page.pdf
- adds a 'path' option to the page.pdf options instead of a separate
`filePath` parameter
- improves on the documentation for the `page.pdf`
References #39.
This patch introduces a general Documentation.diff method, which
produces a diff of two documentations.
With this, the patch teaches documentation linter to lint method arguments.
References #14.
This patch remove remoteDebuggingPort option. Instead, browser
is launched with '--remote-debugging-port=0' flag, letting browser
to pick any port. The puppeteer reads the port number from the
browser's stderr stream.
This change cuts average browser start time from 300ms to 250ms
on my machine. This happens since puppeteer doesn't have to probe
network once every 100ms, waiting for the remote debugging server to
instantiate.
Fixes#21.
This patch changes Page.navigate API:
- Page.navigate now resolves to the main page response
- Page.navigate throws errors if there's no main page response,
e.g. in case of SSL errors, max navigation timeout,
or invalid url.
This patch also adds httpsServer with a self-signed certificates
for the testing purposes.
Fixes#10.
This patch adds browser.stdout and browser.stderr streams.
These streams allow to get the browser instance output, e.g.
```js
browser.stderr.pipe(process.stdout);
```
This line within `injectFile` wasn't doing much of anything:
```js
let expression = fs.readFile(filePath, 'utf8', (err, data) => callback({err, data}));
```
* That's fixed.
* A path error in examples/features.js is fixed.
* Test added for injectFile.
This patch:
- drops Request dependency on NetworkManager
- drops Response dependency on NetworkManager
- drops requestIds from Request and Response objects
This patch implements NetworkManager, which encapsulates all the
interaction with Network domain.
The NetworkManager also uses partial implementation of Request and
Response classes, defined in the Fetch API specification.
References #26
This patch:
- Changes network idle promise to wait for 2 or fewer network requests for at least idleTime (defaults to 5s) before resolving.
- Adds timer cleanup to failure navigation case.
- Adds handling of webSocketClosed.
- Ignores unrecognized requestIds to avoid negative inflight requests.
References #10
This patch introduces the 'request' event which is fired when
page has initiated a request.
The event dispatches an instance of Request class.
References #26.
This patch does a step towards Fetch API:
- implements Request object to some extend. The Request object will be
sent in RequestWillBeSent event.
- implements InterceptedRequest which extends from Request and allows
for request modification. The InterceptedRequest does not
conform to Fetch API spec - there seems to be nothing related to
amending in-flight request.
- adds test to make sure that request can change headers.
References #26
This patch implements Basic Input api:
- Page.focus(selector) - focuses element with selector
- Page.click(selector) - clicks element with selector
- Page.type(text) - types text into a focused element
Fixed#43.
This patch:
- reformats codebase to use 2-spaces instead of 4. This will
align the project with other codebases (e.g. DevTools and Lighthouse)
- enables eslint indentation checking
References #19
It turned out that the tip-of-tree chromium fails to start on Travis
because of two reasons:
- inability to run LinuxSUIDSandbox
- libnss3 library version being too small
Both problems happen because of the outdated "trusty" distribution
which is used on travis.
This patch:
- reverts the previous patch 9e6f779. Instead of introducing such
a weird "api", both phantom_shim/runner.js and test/test.js no
explicitly pass '--no-sandbox' flag to the browser
- updates the libnss3 lib on travis
Fixes#33
This patch implements FrameManager which is responsible for maintaining
the frame tree. FrameManager is quite basic: it sends FrameAttached,
FrameDetached and FrameNavigated events, and can report mainFrame and
all frames.
The next step would be moving certain Page API's to the Frame. For
example, such method as Page.evaluate, Page.navigate and others should
be available on Frame object as well.

Page.screenshot operates the global state of the page. In case of
multiple Page.screenshot() commands running in parallel with different
clipping rects, they interfere with each other.
This patch makes Page.screenshot() commands run sequencially
even though they were called in parallel.
Fixes#15.
This patch refactors Page.screenshot api, accoring to the discussion
in #5:
- Page.screenshot accepts single optional options object
- Page.saveScreenshot is removed
- Page.screenshot assumes 'png' screenshot if no type is set and no
'path' property is given
Fixes#5.
This patch introduces a Dialog class and a new 'dialog'
event instead of the 'alert', 'beforeunload', 'confirm' and
'prompt' events and 'Page.handleDialog' method.
Fixes#2.
This patch makes Page.evaluate await promise if one is
returned by the evaluated code.
This makes the Page.evaluateAsync unneeded, so the patch
removes it.
Fixes#11.
This patch removes the Page.setBlockedURLs method. The
functionality is trivially implementable with the request
interception (see examples/loadurlwithoutcss.js).
Fixes#1.
This patch:
- introduces Request class.
- implements Page.setRequestInterceptor method. The method
allows to install a callback which will be called for every request
with a |Request| object as a single parameter. The callback is free
to override certain request's properties and then either continue or
abort it.
- implements request interception api for phantom-shim and unskips the
module/webpage/abort-network-request.js phantomjs test

This patch drops the chrome-remote-interface dependency and
introduces Connection class which handles all the communication
with remote target.
Closes#3
It turns page.size() and page.setSize() methods are slightly
confusing since there multiple different sizes (layout size,
content size, viewport size..)
This patch renames Page.{size,setSize} methods into
Page.{viewportSize,setViewportSize} methods to avoid confusion.
This patch adds docs/api.md file which contains API description
for the puppeteer API. This patch adds the API outline, which
doesn't not have explanations and samples.
This patch introduces check_availability.js utility which looks for
available chromium binaries for different revisions and platforms.
This patch also re-factors the chromium downloader scripts so that
it can operate different platforms.
This patch implements Puppeteer's Page.setBlockedURLs method.
This is a less agile alternative to the phantom's request.abort()
api.
This patch also adds a loadurlwithoutcss.js example re-implementation
to illustrate the usage of Page.setBlockedURLs.
This patch implements:
- puppeteer's Page.printToPDF method. The method's defaults
are similar to phantom's defaults for the paperSize property.
- phantom's render into pdf file.
The PhantomJS has a similar callback called onInitialized. This
callback passes control to the automation script when the page
gets initialized.
To precisely implement this functionality atop of puppeteer,
and since puppeteer controller script lives in a separate process to
the page, we need an ability to pause page at the moment of
initialization. For now, we are not able to do this.
However, oftentimes clients want to evaluate certain code in
page at the point of page initialization. This patch implements
this capability with the Page.evaluateOnInitilized method call.
This patch also re-implements phantom's unrandomize.js example
with the puppeteer API. This is serves an illustration purpose
for the page.evaluateOnInitilized callback.
With this patch, page has two methods to include javascript:
- Page.addScriptTag(url) which is similar to phantom's includeJs.
- Page.injectFile(filePath) which is similar to phantom's injectJs.
