FastEdge Javascript SDK

Basic Usage

The Javascript code you write will look and feel very much like the Service Workers API .

All incoming HTTP requests will start an instance of your FastEdge application and invoke a fetch event, which can be bound using the addEventListener function:

async function eventHandler(event) {
  const request = event.request;
  return new Response(`You made a request to ${request.url}`);
}


addEventListener('fetch', (event) => {
  event.respondWith(eventHandler(event));
});

The key thing to note is that the addEventListener callback has to synchronously call event.respondWith() with another callback function.

This callback is allowed to be asynchronous, and is usually where you would carry out any custom code, it also has to return a Response object.
