web-ping

JavaScript ping API for use in a web browser context. Released under the BSD-3-Clause license, see LICENSE.

Installation

npm install --save web-ping

Usage

/**
 * Pings a url.
 * @param  {String} url
 * @param  {Number} multiplier - optional, factor to adjust the ping by.  0.3 works well for HTTP servers.
 * @return {Promise} promise that resolves to a ping (ms, float).
 */

Example:

ping('https://google.com/').then(function(delta) {
    console.log('Ping time was ' + String(delta) + ' ms');
}).catch(function(err) {
    console.error('Could not ping remote URL', err);
});

Caveats

The user should be aware that this method relies on the HTTP protocol to ping remote URLs. Consequently, ping times are not as reliable as if they were performed using the ICMP protocol.
