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.
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:
- 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 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 adds support for PUPPETEER_SKIP_CHROMIUM_DOWNLOAD
variable in npm config.
This aligns the variable with the rest of supported environment variables.
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'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:
- starts skipping chromium download if `PUPPETEER_SKIP_CHROMIUM_DOWNLOAD` env variable is set
- adds description of support env variables to the `docs/api.md`.
References #603
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
This patch bumps version to 0.9.1-alpha.
This should emphasize that the documentation is related to the tip-of-tree
version of puppeteer, not to the latest release.
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.
* Replace let with const in examples when appropriate.
* Unify spacing.
* Fix possible copy-paste artifacts.
* Eliminate one unhandled promise rejection ('Target closed').
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:
- 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 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:
- 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.
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.
These commands proved to be over-complicating the documentation source.
We should keep documentation source as simple to edit as possible to
make it friendly to contributions.
This patch keeps the gen:version command as it is non-invasive.
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
The motivation behind the patch:
- examples are probably the most valuable thing in the doc
- currently, one would need to navigate to `page.evaluate` and then
click to the `frame.evaluate` to see the example.
- with this patch, all the descriptions for the shortcut methods are
copied as well. So there's an example for `page.evaluate` right
away.
Drive-by: fix links for `page.$` and `page.$$`
The two tasks allow to copy text from one part of document to another.
This comes handy in organizing the documentation for our shortcut
methods, which should be exactly the same as the original methods.
The tasks work like this:
- the gen:copy(id) task saves a part of document under the name 'ID'.
- the gen:paste(id) task pastes text saved with id 'ID'
This patch also fixes a bunch of links in documentation, as well as
migrating `api.md` to use the two tasks.
This patch implements simple markdown preprocessor. The goal
is to generate certain parts of markdown, such as:
- puppeteer version
- chromium revision
- table-of-contents
- copy/paste parts of documentation (for shortcut methods)
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:
- 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 patch renames page.evaluateOnInitialized into
page.evaluateOnNewDocument to better align with the protocol and with
what the method is actually doing.
Fixes#119.
This patch removes the InterceptedRequest.isHandled method. There's
always a single request interceptor who owns all the intercepted
requests and who know if they were handled.
References #115.
This patch:
- adds Mouse class which holds mouse state and implements mouse primitives,
such as moving, button down and button up.
- implements high-level mouse api, such as `page.click` and `page.hover`.
References #40, References #89
This patch:
- introduces page.waitForSelector to wait for the selector to appear
- introduces polymorphic page.waitFor method, which accepts
either string (and in this case is a shortcut for page.waitForSelector)
or number (and in this case it's a promisified timeout).
References #91.
This patch implements timeout option for page.waitFor. The function
will throw if the selector doesn't appear during timeout milliseconds
of waittime.
References #89, #91.
This patch adds a 'visible' option to the Page.waitFor method, making
it possible to wait for the element to become actually visible.
References #89, #91.
This patch:
- gets rid of `page.emulate` and `page.emulatedDevices`
methods. Instead, it is suggested to use `page.setViewport()`
and `page.setUserAgent()` methods.
- moves DeviceDescriptors to the top level of the puppeteer so that
it is convenient to require them.
- improves on documentation to describe the suggested emulation
approach.
References #88.
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.
References #88.
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:
- 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:
- adds event linting to the doclint
- improves `api.md` to add events and more information about
classes reported by events.
References #14.
This patch unifies Documentation.Method with Documentation.Property,
making it possible to verify sorting order across methods and
properties.
References #14.
This patch:
- fixes a typo in documentation linter, which resulted in only
certain method arguments being linted.
- adds missing arguments to the documentation
References #14.
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 implements documentation linter, which leaves under `test/doclint`
folder.
The documentation linter works like this:
1. Parse javascript source code with esprima and construct a "documentation" out of source code
2. Generate HTML out of `api.md` and traverse the HTML with puppeteer.
3. Make sure javascript aligns nicely with HTML
The documentation linter adds the following commands:
- `yarn doc` - to test that documentation covers all the relevant apis
- `yarn generate-toc` - to update the table-of-contents for the `api.md`
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.
