Package Exports

appium-chromedriver

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (appium-chromedriver) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Local installation

Because of the oddities of npm's lifecycle hooks, installing locally the first time will fail, saying Project does not appear to built yet. Please run gulp transpile first.. This is because we transpile in the prepublish phase, but run the install script in the install phase. Any other way would make development dependencies necessary on user's machines, or make the binary not install, unfortunately.

The solution, however, is simple. Simple run gulp transpile and then npm install. The former will build the project and the latter will simply install the binary.

Usage

import Chromedriver from 'appium-chromedriver';

// 'sync'-like await/Promise usage
async function runSession() {
    let driver = new Chromedriver();
    const desiredCaps = {browserName: 'chrome'};
    await driver.start(desiredCaps);
    let status = await driver.sendCommand('/status', 'GET');
    await driver.stop();
}

// EventEmitter usage
function runSession2() {
    let driver = new Chromedriver();
    const desiredCaps = {browserName: 'chrome'};
    driver.start(desiredCaps);
    driver.on(Chromedriver.EVENT_CHANGED, function (msg) {
        if (msg.state === Chromedriver.STATE_ONLINE) {
            driver.sendCommand('/status', 'GET').then(function (status) {
                driver.stop();
            });
        }
    });
    driver.on(Chromedriver.EVENT_ERROR, function (err) {
        // :-(
    });
}

States

Here's what the Chromedriver state machine looks like:

Chromedriver States

Here are the events you can listen for:

Chromedriver.EVENT_ERROR: gives you an error object
Chromedriver.EVENT_CHANGED: gives you a state change object, with a state property that can be one of:
- Chromedriver.STATE_STOPPED
- Chromedriver.STATE_STARTING
- Chromedriver.STATE_ONLINE
- Chromedriver.STATE_STOPPING
- Chromedriver.STATE_RESTARTING

Custom Chromedriver version

To use a version of Chromedriver not set in the code, use npm config property chromedriver_version.

npm install appium-chromedriver --chromedriver_version="2.16"

Or add the property into your .npmrc file.

chromedriver_version=2.16

Custom binaries url

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

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

Or add the property into your .npmrc file.

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

Another option is to use PATH variable CHROMEDRIVER_CDNURL.

CHROMEDRIVER_CDNURL=http://npm.taobao.org/mirrors/chromedriver npm install appium-chromedriver
