ChromeDriver
=======
[![Build status](https://travis-ci.org/giggio/node-chromedriver.svg)](https://travis-ci.org/giggio/node-chromedriver/) [![Build status](https://ci.appveyor.com/api/projects/status/wr4c16rs5q113vy3?svg=true)](https://ci.appveyor.com/project/giggio/node-chromedriver)
[![npm](https://img.shields.io/npm/dt/chromedriver.svg)](https://www.npmjs.com/package/chromedriver)

An NPM wrapper for Selenium [ChromeDriver](https://sites.google.com/a/chromium.org/chromedriver/).

Building and Installing
-----------------------

```shell
npm install chromedriver
```

Or grab the source and

```shell
node ./install.js
```

What this is really doing is just grabbing a particular "blessed" (by
this module) version of ChromeDriver. As new versions are released
and vetted, this module will be updated accordingly.

The package has been set up to fetch and run ChromeDriver for MacOS (darwin),
Linux based platforms (as identified by nodejs), and Windows.  If you
spot any platform weirdnesses, let us know or send a patch.

### Custom binaries url

To use a mirror of the ChromeDriver binaries use npm config property `chromedriver_cdnurl`.
Default is `http://chromedriver.storage.googleapis.com`.

```shell
npm install chromedriver --chromedriver_cdnurl=https://npm.taobao.org/mirrors/chromedriver
```

Or add property into your [`.npmrc`](https://docs.npmjs.com/files/npmrc) file.

```
chromedriver_cdnurl=https://npm.taobao.org/mirrors/chromedriver
```

Another option is to use PATH variable `CHROMEDRIVER_CDNURL`.

```shell
CHROMEDRIVER_CDNURL=https://npm.taobao.org/mirrors/chromedriver npm install chromedriver
```

### Custom binaries file

To get the chromedriver from the filesystem instead of a web request use the npm config property `chromedriver_filepath`.

```shell
npm install chromedriver --chromedriver_filepath=/path/to/chromedriver_mac64.zip
```

Or add property into your [`.npmrc`](https://docs.npmjs.com/files/npmrc) file.

```
chromedriver_filepath=/path/to/chromedriver_mac64.zip
```

Another option is to use the PATH variable `CHROMEDRIVER_FILEPATH`

```shell
CHROMEDRIVER_FILEPATH=/path/to/chromedriver_mac64.zip
```

Running
-------

```shell
bin/chromedriver [arguments]
```

And npm will install a link to the binary in `node_modules/.bin` as
it is wont to do.

Running with Selenium WebDriver
-------------------------------

```javascript
require('chromedriver');
var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder()
  .forBrowser('chrome')
  .build();
```

(Tested for selenium-webdriver version `2.48.2`)

The path will be added to the process automatically, you don't need to configure it.
But you can get it from `require('chromedriver').path` if you want it.

Running via node
----------------

The package exports a `path` string that contains the path to the
chromdriver binary/executable.

Below is an example of using this package via node.

```javascript
var childProcess = require('child_process');
var chromedriver = require('chromedriver');
var binPath = chromedriver.path;

var childArgs = [
  'some argument'
];

childProcess.execFile(binPath, childArgs, function(err, stdout, stderr) {
  // handle results
});

```

You can also use the start and stop methods:

```javascript
var chromedriver = require('chromedriver');

args = [
	// optional arguments
];
chromedriver.start(args);
// run your tests
chromedriver.stop();

```
Note: if your tests are ran asynchronously, chromedriver.stop() will have to be
executed as a callback at the end of your tests

Versioning
----------

The NPM package version tracks the version of chromedriver that will be installed,
with an additional build number that is used for revisions to the installer.
You can use the package version number to install a specific version, or use the
setting to a specific version. To always install the latest version of Chromedriver,
use `LATEST` as the version number:

```shell
npm install chromedriver --chromedriver_version=LATEST
```

Or add property into your [`.npmrc`](https://docs.npmjs.com/files/npmrc) file.

```
chromedriver_version=LATEST
```

Another option is to use env variable `CHROMEDRIVER_VERSION`.

```shell
CHROMEDRIVER_VERSION=LATEST npm install chromedriver
```

A Note on chromedriver
-------------------

Chromedriver is not a library for NodeJS.

This is an _NPM wrapper_ and can be used to conveniently make ChromeDriver available
It is not a Node JS wrapper.
