Wrangler kv:namespace create "URL_DB" -previewįor creating these KV namespaces, we also need to update our wrangler.toml file to include the namespace bindings accordingly. # This namespace is used for `wrangler dev` local testing: To create a KV, simply run the following commands with Wrangler CLI. s./ UcFDnviQ) while the value would consist of the long URL given by the users. Lucky for us, this does not concern us at all.įor our POC, the key of our KV would be a UUID that follows after our domain name (e.g. a bank transaction between two account balances).
Reading about how KV works, KV is not ideal for situations that require atomic operations (e.g. Through my experiments, I have yet to encounter anything more than a couple of seconds. creating a short URL) may take up to 60 seconds to propagate globally - this is a downside we are okay with. One important note - while KV can support exceptionally high read globally, it is an eventually consistent storage solution. Do note that the limits are applied on a per-account basis.Īs I mentioned earlier, we will be using Cloudflare KV as the database to store our shortened URLs as we are expecting more reads than writes. Overall, I would say that the free tier for Cloudflare Worker and KV is pretty generous and decent enough for our POC. Having that said, let’s stick with a UUID with a length of 8. Looking back, we could have made the length of our UUID ≥ 4 instead of 8 as 62⁴ possibilities are well more than 2.5 million.

As a result, our constraints depend largely on Cloudflare Worker’s pricing and platform limits.Īt the time of writing this, the constraints per account to host our service for free are: The aim is simple - I want to be able to host this service for free.

What follows is my thought process with code examples on how we can create a URL shortener using Cloudflare Worker. While meddling around with Cloudflare Worker to sync the Daily LeetCode Challenge to my Todoist, it gave me an idea to build an actual URL shortener that can be used by anyone.
