Configuration
Sitespeed.io is highly configurable, let’s check it out!
The options #
You have the following options when running sitespeed.io within docker (run docker run sitespeedio/sitespeed.io:8.6.2 --help to get the list on your command line):
bin/sitespeed.js [options] <url>/<file>
Browser
--browsertime.browser, -b, --browser Choose which Browser to use when you test. [choices: "chrome", "firefox"] [default: "chrome"]
--browsertime.iterations, -n How many times you want to test each page [default: 3]
--browsertime.spa, --spa Convenient parameter to use if you test a SPA application: will automatically wait for X seconds after last network activity and use hash in file names. Read https://www.sitespeed.io/documentation/sitespeed.io/spa/ [boolean] [default: false]
--browsertime.connectivity.profile, -c, --connectivity The connectivity profile. To actually set the connectivity you can choose between Docker networks or Throttle, read https://www.sitespeed.io/documentation/sitespeed.io/connectivity/ [choices: "3g", "3gfast", "3gslow", "3gem", "2g", "cable", "native", "custom"] [default: "native"]
--browsertime.connectivity.downstreamKbps, --downstreamKbps This option requires --connectivity be set to "custom".
--browsertime.connectivity.upstreamKbps, --upstreamKbps This option requires --connectivity be set to "custom".
--browsertime.connectivity.latency, --latency This option requires --connectivity be set to "custom".
--browsertime.connectivity.engine Throttle works on Mac and tc based Linux (it is experimental so please use with care). Use external if you set the connectivity outside of Browsertime. The best way do to this is described in https://github.com/sitespeedio/browsertime#connectivity [choices: "throttle", "external"] [default: "external"]
--browsertime.pageCompleteCheck, --pageCompleteCheck Supply a Javascript that decides when the browser is finished loading the page and can start to collect metrics. The Javascript snippet is repeatedly queried to see if page has completed loading (indicated by the script returning true). Use it to fetch timings happening after the loadEventEnd.
--browsertime.pageCompleteWaitTime, --pageCompleteWaitTime How long time you want to wait for your pageComplteteCheck to finish, after it is signaled to closed. Extra parameter passed on to your pageCompleteCheck. [default: 5000]

--browsertime.script, --script Add custom Javascript that collect metrics and run after the page has finished loading. Note that --script can be passed multiple times if you want to collect multiple metrics. The metrics will automatically be pushed to the summary/detailed summary and each individual page + sent to Graphite/InfluxDB.

--browsertime.userAgent, --userAgent The full User Agent string, defaults to the User Agent used by the browsertime.browser option.
--browsertime.preURL, --preURL A URL that will be accessed first by the browser before the URL that you wanna analyze. Use it to fill the cache.
--browsertime.preScript, --preScript Selenium script(s) to run before you test your URL. They will run outside of the analyze phase. Note that --preScript can be passed multiple times.
--browsertime.postScript, --postScript Selenium script(s) to run after you test your URL. They will run outside of the analyze phase. Note that --postScript can be passed multiple times.
--browsertime.delay, --delay Delay between runs, in milliseconds. Use it if your web server needs to rest between runs :)
--browsertime.pageLoadStrategy, --pageLoadStrategy The Page Load Strategy decides when you have control of the page load. Default is normal meaning you will have control after onload. You can change that to none to get control direct after navigation. [choices: "normal", "none"] [default: "normal"]

The basics #
You can analyse a site either by crawling or by feeding sitespeed.io with a list of URLs you want to analyse.
Analyse by URLs #
The simplest way to run sitespeed.io is to give it a URL:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io
If you want to test multiple URLs, then just add them. Each page will be tested with a new browser session, browser cache cleared between each URL.
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io https://www.sitespeed.io/documentation/
You can also use a plain text file with one URL on each line. Create a file called urls.txt:
http://www.yoursite.com/path/
http://www.yoursite.com/my/really/important/page/
http://www.yoursite.com/where/we/are/
Another feature of the plain text file is you can add aliases to the urls.txt file after each URL. To do this, add a non-spaced string after each URL that you would like to alias:
http://www.yoursite.com/ Start_page
http://www.yoursite.com/my/really/important/page/ Important_Page
http://www.yoursite.com/where/we/are/ We_are
Note: Spaces are used to delimit between the URL and the alias, which is why the alias cannot contain one.
Aliases are great in combination with sending metrics to a TSDB (such as Graphite) for shortening the key sent, to make them more user friendly and readable.
And run it:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 urls.txt
You can also add alias directly from the command line. Make yore that you pass on the same amount of alias and URLs.
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --urlAlias doc https://www.sitespeed.io/documumentation/
Pass on multiple –urlAlias for multiple alias/URLs.
If you want to test multiple URLs in a sequence (where the browser cache is not cleared) use –multi:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --multi https://www.sitespeed.io https://www.sitespeed.io/documentation/
If you wanna do more complicated things like log in the user, add items to a cart etc, checkout scripting.
Analyse by crawling #
If you want to find pages that are not so performant it’s a good idea to crawl. Sitespeed.io will start with the URL and fetch all links on that page and continue to dig deeper into the site structure. You can choose how deep to crawl (1=only one page, 2=include links from first page, etc.):
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io -d 2
How many runs per URL? #
When collecting timing metrics, it’s good to test the URL more than one time (default is three times). You can configure how many runs like this (five runs):
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io -n 5
Choose browser #
Choose which browser to use (default is Chrome):
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io -b firefox
Connectivity #
You should throttle the connection when you are fetching metrics. We have a special section on how you emulate connectivity for real users. Make sure you read that parts of the documentation!
Viewport/user agent and mobile #
You can set the viewport & user agent, so you can fake testing a site as a mobile device.
The simplest way is to just add --mobile as a parameter. The viewport will be set to 360x640 and the user agent will be Iphone6. If you use Chrome it will use the preset Apple iPhone 6 device.
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io --mobile
You can also set a specific viewport and user agent:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io --browsertime.viewPort 400x400 --browsertime.userAgent "UCWEB/2.0 (MIDP-2.0; U; Adr 4.4.4; en-US; XT1022) U2/1.0.0 UCBrowser/10.6.0.706 U2/1.0.0 Mobile"
Mobile testing is always best on actual mobile devices. You can test on Android phones using sitespeed.io.
Visual metrics and video #
In 4.1 we released support for recording a video of the browser screen and use that to calculate visual metrics like Speed Index. This is one of the main benefits for using our Docker images, as it makes for an easy setup. Without Docker, you would need to install all the dependencies.
In 6.0 video and Visual Metrics is turned on by default, and if you want to turn them off you do like this:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --visualMetrics false https://www.sitespeed.io/
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --visualMetrics false --video false https://www.sitespeed.io/
First party vs third party #
By default we will categorise the current main domain as first party and the rest as a third party. And you probably wanna categorise requests yourself as first or third parties by adding a regex.
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --firstParty ".ryanair.com" https://www.ryanair.com/us/en/
This is a JavaScript regex and if you need help you should test it out at https://regexr.com to see that it will match.
Output folder or where to store the result #
You can change where you want the data to be stored by setting the --outputFolder parameter. That is good in scenarios where you want to change the default behaviour and put the output in a specific location:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --outputFolder /my/folder ".ryanair.com" https://www.sitespeed.io/
Configuration as JSON #
You can keep all your configuration in a JSON file and then pass it on to sitespeed.io, and override with CLI parameters.
Create a config file and call it config.json:
{
"browsertime": {
"iterations": 5,
"browser": "chrome"
},
"graphite": {
"host": "my.graphite.host",
"namespace": "sitespeed_io.desktopFirstView"
},
"plugins": {
"remove": ["html"]
},
"utc": true
}
Then, run it like this:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --config config.json https://www.sitespeed.io
If you want to override and run the same configuration but using Firefox, you just override with the CLI parameter:
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 --config config.json -b firefox https://www.sitespeed.io
The CLI will always override the JSON config.
Advanced #
Slack #
You can send the result of a run to Slack. First, set up a webhook in the Slack API (https://
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io/ --slack.hookUrl https://hooks.slack.com/services/YOUR/HOOK/URL
You can choose to send just a summary (the summary for all runs), individual runs (with URL), only errors, or everything, by choosing the respective slack.type.
docker run --rm -v "$(pwd)":/sitespeed.io sitespeedio/sitespeed.io:8.6.2 https://www.sitespeed.io/ --slack.hookUrl https://hooks.slack.com/services/YOUR/HOOK/URL --slack.type summary
Log in the user #
We have added a special section for that!
