FetchEvent

This is the event type for fetch events. It contains information about the fetch, including the request and how the receiver will treat the response. It provides the event.respondWith() method, which allows us to provide a response to this fetch.

Instance properties

• FetchEvent.request readonly
  • : The Request that was received by the application.
• FetchEvent.client readonly
  • : Information about the downstream client that made the request.
  • FetchEvent.client.address readonly
    • : A string representation of the IPv4 or IPv6 address of the downstream client.
  • FetchEvent.client.geo readonly
    • : A geolocation dictionary corresponding to the IP address of the downstream client.

Instance methods

• FetchEvent.respondWith()
  • : Provide (a promise for) a response for this request.
• FetchEvent.waitUntil()
  • : Extends the lifetime of the event. Used to notify the host environment of tasks that extend beyond the returning of a response, such as streaming and caching.
