Tracking script reference
The Swetrix.js is a highly customisable tracking script. The following is a reference of all the available functions and options it provides.
init()
This fuction is used to initialise the analytics. Basically you're letting the script know which project do you want to use it with, as well as specifying your custom parameters if needed.
It takes two arguments:
projectID
- the ID of the project you want to use it with.options
- an object with custom options.
Here's an example of how to use this function with all the available options:
swetrix.init('YOUR_PROJECT_ID', {
debug: false,
disabled: false,
respectDNT: false,
apiURL: 'https://api.swetrix.com/log',
})
Name | Description | Default value |
---|---|---|
debug | When set to true, all tracking logs will be printed to console and localhost events will be sent to server. | false |
disabled | When set to true, the tracking library won't send any data to server. Useful for development purposes when this value is set based on '.env' var. | false |
respectDNT | By setting this flag to true, we will not collect ANY kind of data about the user with the DNT setting. This setting is not true by default because our service anonymises all incoming data and does not pass it on to any third parties under any circumstances. | false |
apiURL | Set a custom URL of the API server (for selfhosted variants of Swetrix). | 'https://api.swetrix.com/log' |
track()
With this function you can track any custom events you want. You should never send any identifiable data (like User ID, email, session cookie, etc.) as an event name. The total number of track calls and their conversion rate will be saved.
Here's an example of how to use this function with all the available options:
swetrix.track({
ev: 'YOUR_EVENT_NAME',
unique: false,
})
Name | Description | Default value |
---|---|---|
ev | The event identifier you want to track. This has to be a string, which: 1. Contains only English letters (a-Z A-Z), numbers (0-9), underscores (_) and dots (.). 2. Is fewer than 64 characters. 3. Starts with an English letter. | REQUIRED PARAMETER |
unique | If true, only 1 event with the same ID will be saved per user session. The principle of this parameter is similar to page views and unique views. | false |
trackViews()
Calling trackViews will result in sending the data about the user to our servers. Such data will include the following params if available:
pid
- the unique Project ID request is related to.lc
- users locale (e.g. en_US or uk_UA).tz
- users timezone (e.g. Europe/Helsinki).ref
- the URL of the previous webpage from which a page was opened.so
- the page source ('ref' | 'source' | 'utm_source' GET param).me
- UTM medium ('utm_medium' GET param).ca
- UTM campaign ('utm_campaign' GET param).pg
- the page user currently views (e.g. /hello).perf
- an object which contains performance metrics related to the page load.
On the server side we also gather users IP Address and User Agent. This data is used to detect whether the page view is unique or not.
We DO NOT store neither IP Address nor User Agent as a raw strings, such data is stored as a salted hash for no longer than 30 minutes or 12:00 AM UTC, whatever happens first.
After this timeframe the identifiable data is forever deleted from our servers.
Here's an example of how to use this function with all the available options:
swetrix.trackViews({
unique: false,
ignore: [],
noHeartbeat: false,
heartbeatOnBackground: false,
noUserFlow: false,
doNotAnonymise: false,
})
Name | Description | Default value |
---|---|---|
unique | If true, only unique events will be saved. This param is useful when tracking single-page landing websites. | false |
ignore | A list of regular expressions or string pathes to ignore. For example: ['/dashboard', /^/projects/i] setting will force script to ignore all pathes which start with /projects or equal to /dashboard .Please pay attention, that the pathes always start with / . | [] |
noHeartbeat | Do not send Heartbeat requests to the server. By setting this to true you will not be able to see the realtime amount of users on your website. | false |
heartbeatOnBackground | Send Heartbeat requests when the website tab is not active in the browser. Setting this to true means that users who opened your website in inactive browser tab or window will not be counted into users realtime statistics.Setting this to true is usually useful for services like Spotify or Youtube. | false |
noUserFlow | Send previous page user visited to the server, only the pages on your website will be sent. Setting this to true means that no user flow analytics will be sent and as a consequence it won't be available to you later in Dashboard. | false |
doNotAnonymise | Do not send paths from ignore list to API. If set to false , the page view information will be sent to the Swetrix API, but the page will be displayed as a 'Redacted page' in the dashboard. | false |
The trackViews
function returns a Promise
with an object with some methods allowing you to alter the behaviour of page tracking:
{
// This function stops the tracking of pages.
stop() {},
}
