When building web applications with audio or video players, it is often necessary to persist user-specific settings such as volume, playback speed, muted state, or even the current position within the media file. One convenient way to achieve this is by utilizing the session storage feature in JavaScript.

Session storage allows you to store key-value pairs in the user’s browser and retrieve them later during the same browsing session. Unlike local storage, which persists data across multiple sessions, session storage is cleared when the user closes the browser tab or window.

The Session Storage API

The session storage API provides a simple and intuitive way to interact with the session storage object. It exposes methods to store, retrieve, and remove data from the session storage.

To store user-specific audio/video player settings in session storage, you can follow these steps:

1. Storing Player Settings: Whenever a user changes a setting such as volume or playback speed, you can update the corresponding session storage key-value pair. For example, to store the volume setting:

   sessionStorage.setItem('playerVolume', player.volume);
   

2. Retrieving Player Settings: When initializing the audio/video player, you can retrieve the user-specific settings from session storage and apply them to the player instance. For example, to retrieve the volume setting:

   const volumeSetting = sessionStorage.getItem('playerVolume');
      
   if (volumeSetting) {
     player.volume = parseFloat(volumeSetting);
   }
   

3. Clearing Player Settings: If the user wants to reset all the settings, you can clear the corresponding session storage keys. For example, to clear the volume setting:

   sessionStorage.removeItem('playerVolume');
   

Remember that session storage is limited in size (usually around 5MB per origin) and only persists data for the duration of the browsing session. If you need to persist settings across multiple sessions or larger amounts of data, consider using local storage or a server-side solution.

Conclusion

Using session storage in JavaScript is a convenient way to persist user-specific audio/video player settings within a browsing session. By storing and retrieving settings using session storage API methods, you can provide a personalized experience for users each time they interact with your audio/video player.
