Examples

In this example we attempt to retrieve an entry from the Fastly Cache, and return a message stating whether the entry was in the Fastly Cache or not.

/// <reference types="@fastly/js-compute" />

import { SimpleCache } from 'fastly:cache';

addEventListener('fetch', event => event.respondWith(app(event)));

async function app(event) {
  const path = new URL(event.request.url).pathname;
  let page = SimpleCache.get(path);
  return new Response(page ? `${path} is in the cache` : `${path} is not in the cache`, {
    headers: {
      'content-type': 'text/plain;charset=UTF-8'
    }
  });
}
