The RudderStack JavaScript API makes it easy for you to send your customer event data from your website to any destination in no time. After integrating this SDK, you will also be able to connect your website to multiple destinations such as Google Analytics, Hotjar, Amplitude, and more, to send your event data in real-time.

To load analytics.js correctly, copy either the minified or non-minified version of the code given in our documentation. To test if the library is loaded correctly, open the JavaScript console on your browser and run this command: rudderanalytics. If the command returns an object, the library is loaded successfully. If not, please verify if you have set up rudderanalytics.js correctly.

The different key methods used in the JavaScript SDK APIs are load(), identify(), page(), track(), alias(). While the load() method is used to load rudder-analytics.js on your website, the other API calls are used to get information related to the user and their actions on the website.
