Hidden directory that Wrangler creates in the project root. Contains the local state of all Cloudflare services: the "local cloud" on your machine.

The D1 SQLite files live here. When you write to D1 locally (--local), the rows go into .wrangler/state/v3/d1/.../*.sqlite. That IS the local database: no separate server, no daemon, just a file.
wrangler d1 export --local reads from these SQLite files and generates a dump.sql, the transport file you can then execute against the remote DB. The data flows: .wrangler/ → dump.sql → remote D1.
Workers KV local data, R2 local buckets, all simulated here too. Same pattern: local files that mimic the cloud service.
Lives in .gitignore. GitHub never sees it. Code deploys (GitHub Actions, wrangler pages deploy) push dist/ + functions/ only. .wrangler/ stays on your machine.
If you delete .wrangler/, you lose all local data. Next wrangler dev recreates the directory structure but the data is gone. Pull from remote to restore.
No config needed. Wrangler creates and manages it automatically based on wrangler.toml bindings.
