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:
- 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:
- 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.
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.
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.
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 refactors doclint so that more checks and more generators
could be added.
This patch:
- Introduces 'Source' class, which holds file content in-memory and
allows it to be updated.
- Introduces 'Message' class - which is a pair of a text and a type.
Messages could have either 'error' type or 'warning' type.
Refactor Frame.waitForSelector to make room for Frame.waitForFunction
implementation.
This patch:
- removes AwaitedElement class which proved to be confusing, and
introduces a more straight-forward WaitTask.
- refactors the mutation observer to return true in case of successful
waiting or false in case of timeout.

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 teaches doclint to regenerate table of contents
automatically whenever it's needed.
This patch:
- splits lint.js into lint.js and cli.js
- teaches cli.js to generate table-of-contents
- removes the test for table-of-contents errors from doclint
- adds a test for doclint failing to parse object destructuring in
method parameters.
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 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.
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 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:
- 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:
- moves doclint under utils/ folder
- adds tests to verify doclint basic functionality
This patch also drops the jasmine as a spec runner for the doclint
checks. It turned out it's hard to customize jasmine's behavior,
so instead this patch implements a dummy spec runner.
The dummy spec runner allows us:
- to format messages however we want (the custom jasmine reporter would
also allow us to do this)
- to avoid `beforeAll` functions which pollute global to pass
initialized variables over to specs

Currently, after the chromium was rolled to a new revision, the
previsious revision is kept downloaded in the puppeteer folder.
Since every revision is ~70Mb, it quickly piles up.
This patch removes previous downloaded chromium revisions after
a new one is successfully installed.
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
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.
