feat(interception): Implement request.respond method
This patch implements a new Request.respond method. This
allows users to fulfill the intercepted request with a hand-crafted
response if they wish so.
References #1020.
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 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:
- 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.
References #65.
This patch:
- adds input methods to ElementHandle, such as ElementHandle.type and ElementHandle.press
- changes `page.type` to accept selector as the first argument
- removes `page.press` method. The `page.press` is rarely used and doesn't operate with selectors; if there's a need to press a button, `page.keyboard.press` should be used.
BREAKING CHANGE: `page.type` is changed, `page.press` is removed.
Fixes#241.
This patch:
- introduces ExecutionContext class that incapsulates javascript
execution context. An examples of execution contexts are workers and
frames
- introduces JSHandle that holds a references to the javascript
object in ExecutionContext
- inherits ElementHandle from JSHandle
Fixes#382.
This patch allows passing 0 to disable timeout for the following methods:
- page.goto
- page.waitForNavigation
- page.goForward
- page.goBack
Fixes#782.
This patch starts using taskkill program on windows to gracefully
terminate chrome.
Note: this slows down chrome shutdown on Windows in case of using
custom userDataDir. This is because chrome takes some time to shutdown
its operations and leave profile directory in a consistent state.
Fixes#839.
This patch introduces ConsoleMessage type and starts dispatching
it for the 'console' event.
BREAKING CHANGE: this breaks the api of the 'console' event.
Fixes#744.
This patch rolls chromium to r503964.
Note: since the plznavigate is not supported by puppeteer right now, the
patch also starts passing the `--disable-browser-side-navigation` flag.
This is a temporary work around for us.
References #877.
This lets the user pass `...args` into `page.waitFor`. It also clarifies that the docs that `options` is not optional if `...args` are specified.
Fixes#770
Since protocol ignores all HTTP headers that don't have string
value, this patch starts validating header key-values before
sending them over the protocol.
Fixes#713.
This patch:
- makes `browser.close()` return a promise that resolves when browser gets closed
- starts closing chrome gracefully if a custom `userDataDir` is supplied
Fixes#527
This patch:
- teaches `page.evaluate` to accept ElementHandles as parameters
- removes `ElementHandle.evaluate` method since it's not needed any
more
References #382
It turns out that [undefined, 1].join(',') results in ",1" instead
of "undefined,1". This causes a syntax error when trying to pass undefined
as a first argument to `page.evaluate` method.
Fixes#572.
Currently, navigation watcher throws exception if timeout
is exceeded.
Due to the way it is used in `page.navigate`, the promise
get's rejected before it is awaited, which is considered to
be "unhandled promise rejection".
Fixes#738
It's very bad to have 'unhandled promise rejection' that can't be
handled in user code. These errors will exit node process in a near
future.
This patch avoids 'unhandled promise rejection' while sending protocol
messages.
This patch:
- introduces `puppeteer:error` debug scope and starts using it for all
swalloed errors.
- makes sure that every `client.send` method is either awaited or its
errors are handled.
- starts return promises from Request.continue() and Request.abort().
- starts swallow errors from Request.contine() and Request.abort().
The last is the most important part of the patch. Since
`Request.continue()` might try to continue canceled request, we should
disregard the error.
Fixes#627.
This patch:
- adds `page.touchscreen` namespace, similar to `page.mouse` and `page.keyboard`.
- adds tapping to multiple layers:
- `page.touchscreen.tap`
- `page.tap` - convenience method which accepts selector
- `elementHandle.tap`
Fixes#568 and #569.
This patch:
- switches to objects instead of maps for headers (in Request, Response and
page.setExtraHTTPHeaders)
- converts all header names to lower case
Fixes#547, fixes#509
It turned out that either Network.requestIntercepted or
Network.requestWillBeSent occasionally report encoded URL.
This patch starts decoding URL's when generating request hash.
Fixes#558.
This patch rolls chromium to r496140. This includes the r496130 that
introduces multiple sessions for single target.
With this patch, it is possible to run puppeteer in headful mode
and open devtools over the automated pages without puppeteer losing
connection to the page.
This patch:
- adds a 'timeout' launcher option that constrains the time for chromium to launch.
- adds a 'handleSIGINT' launcher option that is `true` by default and that closes chrome instance
Fixes#363.
Fail gracefully when chromium failed to download
This patch changes both install.js and Launcher.js to inform how
chromium could be downloaded manually.
This patch:
- removes the `page.uploadFile` method
- adds `elementHandle.uploadFile` method.
Motivation: `elementHandle.uploadFile` is rarely used, so it doesn't worth it
to keep it on page.
This patch:
- rolls chromium to r494365
- starts using Runtime.evaluate(awaitPromise: true), with new semantic
we can avoid additional Runtime.awaitPromise call
- stops resolving promises for Console event
This patch:
- refactors Connection to use a single remote debugging URL instead of a
pair of port and browserTargetId
- introduces Puppeteer.connect() method to attach to already running
browser instance.
Fixes#238.
This patch:
- teaches request interception to ignore data URLs. Currently protocol
doesn't send interceptions for data URLs.
- teaches request interception to properly process URLs with hashes.
Currently `Network.requestIntercepted` sends url with a hash, whereas
`Network.requestWillBeSent` doesn't report hashes in its urls. @see
crbug.com/755456
- skips one more header that I spotted during debugging interception on
the realworld websites.
Fixes#258, #259.
This patch starts emitting 'error' event when page crashes.
'error' events have special treatment in node, so page crashes
become observable for users.
Fixes#262.
This patch:
- fixes multimap implementation to work properly in node
- moves ESTreeWalker from third-party into utils/doclint. ESTreeWalker
license is compliant with Apache2.0.
This patch:
- split browser launching logic from Browser into `lib/Launcher.js`
- introduce `puppeteer` namespace which currently has a single `launch`
method to start a browser
With this patch, the browser is no longer created with the `new
Browser(..)` command. Instead, it should be "launched" via the
`puppeteer.launch` method:
```js
const puppeteer = require('puppeteer');
puppeteer.launch().then(async browser => {
...
});
```
With this approach browser instance lifetime matches the lifetime of
actual browser process. This helps us:
- remove proxy streams, e.g. browser.stderr and browser.stdout
- cleanup browser class and make it possible to connect to remote
browser
- introduce events on the browser instance, e.g. 'page' event. In case
of lazy-launching browser, we should've launch browser when an event
listener is added, which is unneded comlpexity.
Mouse events are no longer racy. Enabling touch no longer converts all mouse events into touches. Promises in destroyed execution contexts are rejected immediately.
The issue #168 is a protocol inconsistency which happens only
in case of HTTPS error. This patch starts refering to the
upstream bug instead of puppeteer issue.
Closes#168.
This patch
- rolls chromium to 492629
- migrates connection establishing to use browser target. This migration means
that now we have a single websocket connection to browser (implemented
in Connection class). A connection to a particular target is
incapsulated in a new Session class.
This patch:
- changes interception API so that it better aligns with what we'd like to see
in #121
- fixes the issue with redirect interception
Fixes#217.
This patch starts using "Failed" command for request interception instead of
"Aborted".
The "Aborted" status also has a side-effect of cancelling the navigation, so
there will be no error on the page and form puppeteer's standpoint, the navigation
will never complete.
The `DEBUG=*page npm run unit` is too verbose due to events spamming
the console.
This patch starts tracing emitted events only if there are any
listeners.
This patch implements 'autoRepeat' functionality for `keyboard.down`.
With this patch, the subsequent calls to `keyboard.down` would generate
an event with 'autoRepeat` flag set to true.
Closes#157
This patch makes sure that request.text() doesn't try
to fetch response body from the backend until the request is
actually finished (finished or failed).
It turns out we're not receiving 'Network.requestWillBeSent' event
for every requestId.
This patch makes sure we don't dispatch `requestfinished` and
`requestfailed` events without passing actual request.
References #168
VolumeUp, VolumeDown, and VolumeMute were changed to AudioVolumeUp, AudioVolumeDown, and AudioVolumeMute
The media keys like MediaTrackNext were also missing, so I added them.
This patch:
- teaches page.uploadFile() to resolve given file paths against
current working directory. This aligns paths handling with all the
other methods
- moves page.uploadFile() under Frame
- changes test to use relative path for file upload
The Body class was inlined in the Request and Response classes.
This patch:
- removes the Body class
- adds Request.postData public property
- adds Response.buffer(), Response.text() and Response.json() methods
Fixes#106.
The page.waitForFunction method allows to wait for a general predicate.
The predicate will be continiously polled for in page, until
it either returns true or the timeout happens.
The polling parameter could be one of the following:
- 'raf' - to poll on every animation frame
- 'mutation' - to poll on every dom mutation
- <number> - to poll every X milliseconds
References #91
This patch:
- implements a basic public API coverage based on 'helper.tracePublicAPI' methods
- adds `npm run coverage` command which reports coverage after running all of the unit tests
References #50.
This patch:
- removes Body.arrayBuffer. This method is redundant since there's
already a Body.buffer() method
- removes Body.bodyUsed getter.
References #106
This patch:
- renames page.setHTTPHeaders into page.setExtraHTTPHeaders
- starts using Map instead of Object to align with other headers
arguments
Fixes#112.
This patch improves on page.evaluate to accept a string.
The string can have a trailing '//# sourceURL=' comment which would
name the evaluation to make stacks beautiful.
In order to make sourceURL comments possible, this patch:
- removes wrapping of the client function into `Promise.resolve()`
- stops passing `awaitPromise` parameter to `Runtime.evaluate`
- starts to await promise via the `Runtime.awaitPromise` if the return type of the evaluation
is promise
closes#118
This patch removes Header class and substitutes it with a simple
Map object.
The map is chosen over the vanilla object since it has explicit
order of headers which we'd like to preserve.
References #106.
This patchs makes sure DOM domain is never enabled. The reasoning behind this is that
DOM domain is heavy-weight: it generates a lot of traffic over the protocol.
Drive-by: use Page.addScriptToEvaluateOnNewDocument instead of Page.addScriptToEvaluateOnLoad
