Hi, I want to make an API using CloudFlare Workers. Can you please tell me how the server time is calculated? Will it be taken into account while the program is waiting for a response from the upstream API?llo, is this normal?

It’s also interesting whether waiting for a response from upstash redis will be taken into account in the server time

is there a way to push a local database to the remote one?

Dump the Local Database, then run the query against the remote one?

Ok, thanks. My API makes 3 requests to higher APIs to give a response to the user. Are outgoing requests charged in this case?

Replace express with https://honojs.dev

Hono is a small, simple, and ultrafast web framework for the Edges. It works on Cloudflare Workers, Fastly Compute, Deno, Bun, Vercel, Netlify, AWS Lambda, Lambda@Edge, and Node.js. Fast, but not only fast.

I am currently writing a kv tool function. Now I can only get the instance in env. Does anyone know of other ways to get an instance? I don't want to mix utility functions with env.

marsolegOP•7/30/24, 9:00 AM

Hi, my program needs to do caching to work. I read upstash documentation and liked it. But I don't understand why it uses Rest API instead of TCP, even though Cloudflare supports it. Also, I'd be glad if you tell me more about caching methods in Cloudflare Workers.

Erisa•7/30/24, 9:32 AM

upstash support for workers has been around for much longer than tcp support has been and frankly sending off a fetch is still a lot easier to explain, so they probably never found benefit in providing guides for tcp. it should work just fine though, if you work out how to interact with redis over a raw tcp socket

Jonathan Silva•7/31/24, 2:36 AM

To use module workers do I need the wrangler.toml file ?

I create the Worker via API and it is not possible to create this file
