    ChromeDriver

    Build Status Build Status npm

    An NPM wrapper for Selenium ChromeDriver.

    Building and Installing

    npm install chromedriver

    Or grab the source and

    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 Node.js), and Windows. If you spot any platform weirdness, let us know or send a patch.

    Force download

    By default this package, when installed, will search for an existing Chromedriver binary in your configured temp directory. If found, and it is the correct version, it will simply copy it to your node_modules directory. You can force it always download by configuring it:

    npm install chromedriver --chromedriver-force-download

    Or add property into your .npmrc file.

    chromedriver_force_download=true
    

    Another option is to use PATH variable CHROMEDRIVER_FORCE_DOWNLOAD.

    CHROMEDRIVER_FORCE_DOWNLOAD=true npm install chromedriver

    Custom binaries url

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

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

    Or add property into your .npmrc file.

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

    Another option is to use PATH variable CHROMEDRIVER_CDNURL.

    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.

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

    Or add property into your .npmrc file.

    chromedriver_filepath=/path/to/chromedriver_mac64.zip
    

    Another option is to use the PATH variable CHROMEDRIVER_FILEPATH

    CHROMEDRIVER_FILEPATH=/path/to/chromedriver_mac64.zip

    This variable can be used to set either a .zip file or the binary itself, eg:

    CHROMEDRIVER_FILEPATH=/bin/chromedriver

    Custom download options

    Install through a proxy.

    npm config set proxy http://[user:pwd]@domain.tld:port
    npm config set https-proxy http://[user:pwd]@domain.tld:port

    Use different User-Agent.

    npm config set user-agent "Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0"

    Skipping chromedriver download

    You may wish to skip the downloading of the chromedriver binary file, for example if you know for certain that it is already there or if you want to use a system binary and just use this module as an interface to interact with it.

    To achieve this you can use the npm config property chromedriver_skip_download.

    npm install chromedriver --chromedriver_skip_download=true

    Or add property into your .npmrc file.

    chromedriver_skip_download=true
    

    Another option is to use the PATH variable CHROMEDRIVER_SKIP_DOWNLOAD

    CHROMEDRIVER_SKIP_DOWNLOAD=true

    Running

    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

    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 chromedriver binary/executable.

    Below is an example of using this package via node.

    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:

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

    With the latest version, you can optionally receive a Promise from the chromedriver.start function:

    var returnPromise = true;
    chromedriver
      .start(args, returnPromise)
      .then(() => {
        console.log('chromedriver is ready');
      });

    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. If there is a new Chromedriver version available which is not yet available as a version of node-chromedriver, the npm command npm run update-chromedriver in this repository can be used to make the required updates to this module, please submit the change as a PR. To always install the latest version of Chromedriver, use LATEST as the version number:

    npm install chromedriver --chromedriver_version=LATEST

    Or add property into your .npmrc file.

    chromedriver_version=LATEST
    

    Another option is to use env variable CHROMEDRIVER_VERSION.

    CHROMEDRIVER_VERSION=LATEST npm install chromedriver

    You can force the latest release for a specific major version by specifying LATEST_{VERSION_NUMBER}:

    CHROMEDRIVER_VERSION=LATEST_80 npm install chromedriver

    You can also force a different version of chromedriver by replacing LATEST with a version number:

    CHROMEDRIVER_VERSION=75.0.3770.140 npm install chromedriver

    Detect ChromeDriver Version

    The NPM package version may not be always compatible to your Chrome version. To get the chromedriver that corresponds to the version of Chrome installed, you can use the npm config property detect_chromedriver_version.

    npm install chromedriver --detect_chromedriver_version

    Or add property into your .npmrc file.

    detect_chromedriver_version=true
    

    Another option is to use environment variable DETECT_CHROMEDRIVER_VERSION.

    DETECT_CHROMEDRIVER_VERSION=true npm install chromedriver

    Note: When the property detect_chromedriver_version is provided, chromedriver_version and chromedriver_filepath properties are ignored.

    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.

    Supported Node.js versions

    We will do our best to support every supported Node.js versions. See nodejs/Release for the current supported versions. You can also view our build scripts and check the versions there.

    Contributing

    Questions, comments, bug reports, and pull requests are all welcome. Submit them at the project on GitHub.

    Bug reports that include steps-to-reproduce (including code) are the best. Even better, make them in the form of pull requests.

    We have added VS Code Remote support with containers. If you are on Windows, set git config core.autocrlf input so you don't get git errors.
