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 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 unifies node6 transpilation:
- instead of generating multiple top-level directories, prefixed with
`node6-`, all transpiled code gets placed under single `node6/` folder
- transpilation doesn't change require paths of transpiled modules any
more
This patch:
- introduces a transpiler which substitutes async/await logic with
generators.
- starts using the transpiler to generate a node6-compatible version of puppeteer
- introduces a runtime-check to decide which version of code to use
Fixes#316.
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:
- 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

This patch:
- moves phantom shim shell into a bin/ folder
- introduces a new root index.js which exposes Browser to the
dependent modules
- adds forgotten LICENSE header to the install.js
