length of your list -> then access that array item directly. flareutils library and I see there's also a list method combining cache and kv. cacheKey = new URL("https://list.better.kv"); axios on Workers, which is sounds like you're trying to dofetch for HTTP calls in Workers. But in Workers, you don't need to do that You can use a KV binding: https://developers.cloudflare.com/workers/runtime-apis/kv/#kv-bindings
axios uses Node's http module, which doesn't exist in Workers. Workers run JavaScript via V8, but not Node.js@cloudflare/workers-types. There's a KVNamespace type which you can assign to env.KV_BINDING or similar, which should work wellfetch is the future anyway especially now it's in Node!fetch is the standard within browsers and runtimes. Having that consistency is really good and it's native!Keys have a maximum length of 512 bytes.
