to-do-list-kv-template
cloudflare/templates
Official starter for a to-do list stored in Workers KV. It is the smallest template that makes the write-price difference obvious: creating a task is a write, loading the list is a read.
A personal list fits in the Free daily write cap. A shared list with many clients will hit 1,000 writes a day long before it hits the read cap.
Products: Workers and KV.
