The bowser npm package is a browser detection library. It helps in identifying the browser and rendering engine a user is using, as well as providing information about the browser's capabilities, such as whether it supports touch events or service workers. This can be particularly useful for tailoring user experiences to different environments or for analytics and debugging purposes.
