@nozbe/periscope-client

A public (not open-source though) protocol allowing for transferring files across windows and frames.

Terminology

• inlet - the part that takes the file and sends it to the other end of the periscope where it should be displayed. Usually, this is going be your main content, eg. a React/Vue/Angular app etc., that needs to stay safe.

• outlet - the part that receives the file from the inlet so it can be processed and displayed in isolation. Usually, this is going be an iframe rendered inside of your app.

• peeking - the action of sending a file or some other content from the inlet to have it displayed in the outlet.

Known limitations

• You can't have more than one periscope per inlet window at once.
• Doesn't support light/dark mode features
