Currently, JSHandle.jsonValue() is implemented as in-page JSON.stringify
call and consequent JSON.parse in node. This approach proved to be
unfortunate for automation purposes: if page author overrode the
Object.prototype.toJSON method, then it's harder for puppeteer to
interact with the page.
This patch switches JSHandle.jsonValue to use protocol serialization
that ignores toJSON property. THis also changes the `page.evaluate`
behavior since it is based on JSHandle.jsonValue().
Fixes#1003.
BREAKING CHANGE:
`page.evaluate` no longer calls toJSON when generating return value.
For the old behavior, do JSON.parse/JSON.stringify manually:
```js
const json = JSON.parse(await page.evaluate(() => JSON.stringify(obj)));
```
This roll includes the following important revisions:
- https://crrev.com/509990 - DevTools: Allow location to be specified in
Input.dispatchKeyEvent
- https://crrev.com/509486 - DevTools: fix extra HTTP headers not sent
on browser navigation request

This patch:
- introduces Target class that represents any inspectable target, such as service worker or page
- emits events when targets come and go
- introduces target.page() to instantiate a page from a target
Fixes#386, fixes#443.
Similarly to the `request.response()` method, this patch adds
`request.failure()` method that returns error details for the failed
requests.
Fixes#901.
This patch:
- changes `browser.close` to terminate browser.
- introduces new `browser.disconnect` to disconnect from a browser without closing it
This patch: fixes#918, fixes#989
BREAKING CHANGE:
`browser.close()` will always close a browser, even if it was initialized with
`puppeteer.connect`. To disconnect from a remote browser, use `browser.disconnect()` instead.
This patch starts generating input events for `keyboard.down`, addressing bullet 2 of
#723. With this patch, there's no longer any difference between `keboard.press('a')` and
`keyboard.press('a', {text: 'a'})`.
BREAKING CHANGE:
`keyboard.down('a')` starts generating input event (wasn't the case before).
References #723
This patch:
- deprecates injectFile as it was confused with the addScriptTag
- accepts an options object in addScriptTag which supports properties url, path and content.
- accepts an options object in addStyleTag which supports properties url, path and content.
Fixes#949.
BREAKING CHANGE:
- the addStyleTag/addScriptTag have changed;
- the injectFile was removed in favor of (addStyleTag({path:}).
This patch introduces `Page.queryObjects` and
`ExecutionContext.queryObjects` methods to query JavaScript heap
for objects with a certain prototype.
Fixes#304.
This patch improves life of puppeteer contributor on Windows:
- Setting environment variables using cross-env since Windows requires the SET command.
- Calling Jasmine in the script debug-unit using jasmine's JavaScript binary instead of shell.
- Add /test/test-user-data-dir* to .gitignore since temporary user data directories, in case of test
fails, remains in the test directory.
This patch:
- introduces `helper.promisify` - a simple polyfill for the `util.promisify`. The
`util.promisify` could not be used due to Node6 compatibility issues.
- migrates all sync filesystem operations to the async replicas
Fixes#884.
The page.plainText is confusing: it's unclear what kind of text it
returns, textContent or innerText. It's also easily polyfillable and
doesn't seem to be used.
BREAKING CHANGE: the page.plainText is not existing any more.
Instead, use `page.evaluate(() => document.body.innerText)`.
This patch:
- updates JSHandle.toString to make a nicer description for primitives
- excludes JSHandle.toString from documentation to avoid its abuse
References #382
This patch moves resourceType to be all small-caps. This aligns
with our convention that all string constants should be smallcaps.
BREAKING CHANGE: this patch changes the constants of the
request.resourceType to be all small-caps.
This patch:
- adds `ElementHandle.boundingBox()` method to get bounding box of element relative
to the page
- adds `ElementHandle.screenshot()` method to capture a screenshot of an element
This patch starts using typescript to lint JSDoc annotations.
Note: this uses typescript's bleeding edge. We should migrate to stable once
it has all the necessary bugfixes.
