Cloudflare wrangler.toml Generator

wrangler.toml tells Cloudflare which file is your Worker, what name it deploys under and which resources it can reach. Newcomers usually trip on compatibility_date and on bindings: without them, or with the wrong KV id, wrangler deploy stops with an error. This page shows a minimal Worker config carrying a name, an entry point, a compatibility date, one variable and a KV binding.

The page has no inputs: the TOML is fixed, already rendered on load, and the button only redraws it. Two honest caveats. This is a Workers config, not a Pages one, and a Pages project uses pages_build_output_dir with a different layout. And despite what the tool description claims, there is no routes key in the output, so add routes or route yourself if you need a custom domain.

Replace your-kv-namespace-id with the real one, which wrangler kv namespace create CACHE prints for you, or delete the whole [[kv_namespaces]] block, because the placeholder alone fails the deploy. Bump compatibility_date to today for a new project; the 2024 value pins the runtime to older behavior. And keep tokens out of [vars], which goes into git: use wrangler secret put.
