* feat: Set which browser to launch via PUPPETEER_PRODUCT
This change introduces a PUPPETEER_PRODUCT environment
variable as a first step toward using Puppeteer with
many different browsers. Setting PUPPETEER_PRODUCT=firefox, for
example, enables Firefox-specific Launcher settings.
The state is also exposed as `puppeteer.product` in the API
to support adding other product-specific behaviour as needed.
The bulk of the change is a refactoring in Launcher
to decouple generic browser start-up from product-specific
configuration.
Respecting the puppeteer-core restriction for PUPPETEER_
environment variables, lazily instantiate the Launcher
based on a `product` Puppeteer.launch option, if available.
* test: Distinguish Juggler unit tests from Firefox
The funit script is renamed to fjunit (j for Juggler, which is
used only by the experimental puppeteer-firefox package.
In contrast, the funit script now refers to running Puppeteer
unit tests against the main puppeteer package with Firefox.
To do so with Firefox Nightly, run:
`BINARY=path/to/firefox npm run funit`
A number of changes in this patch make it easier to run
Puppeteer unit tests in Mozilla's CI.
These getters are introduced as a more convenient substitute for
a `require('puppeteer/Errors')` and
`require('puppeteer/DeviceDescriptors')`.
This way we can make cross-browser story nicer - a single require
of `puppeteer` or `puppeteer-firefox` fully defines Puppeteer
environment.
Introduce `//lib/api.js` that declares a list of publicly exposed
classes.
The `//lib/api.js` list superceedes dynamic `helper.tracePublicAPI()` calls
and is used in the following places:
- [ASYNC STACKS]: generate "async stacks" for publicy exposed API in `//index.js`
- [COVERAGE]: move coverage support from `//lib/helper` to `//test/utils`
- [DOCLINT]: get rid of 'exluded classes' hardcoded list
This will help us to re-use our coverage and doclint infrastructure
for Puppeteer-Firefox.
Drive-By: it turns out we didn't run coverage for `SecurityDetails`
class, so we lack coverage for a few methods there. These are excluded
for now, sanity tests will be added in a follow-up.
This patch:
- adds experimental "transport" option to pptr.connect
- uses "transport" option to make sure Puppeteer-Web works with
Target.exposeDevToolsProtocol
Drive-by: add `browser.target()` to access browser target.
This patch removes all dynamic requires in Puppeteer. This should
make it much simpler to bundle puppeteer/puppeteer-core packages.
We used dynamic requires in a few places in lib/:
- BrowserFetcher was choosing between `http` and `https` based on some
runtime value. This was easy to fix with explicit `require`.
- BrowserFetcher and Launcher needed to know project root to store
chromium revisions and to read package name and chromium revision from
package.json. (projectRoot value would be different in node6).
Instead of doing a backwards logic to infer these
variables, we now pass them directly from `//index.js`.
With this patch, I was able to bundle Puppeteer using browserify and
the following config in `package.json`:
```json
"browser": {
"./lib/BrowserFetcher.js": false,
"ws": "./lib/BrowserWebSocket",
"fs": false,
"child_process": false,
"rimraf": false,
"readline": false
}
```
(where `lib/BrowserWebSocket.js` is a courtesy of @Janpot from
https://github.com/GoogleChrome/puppeteer/pull/2374/)
And command:
```sh
$ browserify -r puppeteer:./index.js > ppweb.js
```

This patch introduces `BrowserFetcher` class that manages
downloaded versions of products.
This patch:
- shapes Downloader API to be minimal yet usable for our needs. This
includes removing such methods as `Downloader.supportedPlatforms` and
`Downloader.defaultRevision`.
- makes most of the fs-related methods in Downloader async. The only
exception is the `Downloader.revisionInfo`: it has stay sync due to the
`pptr.executablePath()` method being sync.
- updates `install.js` and `utils/check_availability.js` to use new API
- finally, renames `Downloader` into `BrowserFetcher`
Fixes#1748.
This patch:
- adds `puppeteer.defaultArgs()` method to get default arguments that are used to launch chrome
- adds `ignoreDefaultArgs` option to `puppeteer.launch` to avoid using default puppeteer arguments
Fixes#872
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.
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:
- 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:
- 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.
