| 11 | +Today [we announced the public beta](https://github.com/cloudflare/workers-sdk/discussions/9660) of [remote bindings](/workers/development-testing/#remote-bindings) for local development. With remote bindings, you can now connect to deployed resources like [R2 buckets](/r2/) and [D1 databases](/d1/) while running Worker code on your local machine. This means you can test your local code changes against real data and services, without the overhead of deploying for each iteration. |
| 12 | + |
| 13 | +## Example configuration |
| 14 | + |
| 15 | +To enable remote mode, add `"experimental_remote" : true` to each binding that you want to rely on a remote resource running on Cloudflare: |
| 16 | + |
| 17 | +<WranglerConfig> |
| 18 | + |
| 19 | +```jsonc title="wrangler.jsonc" |
| 20 | +{ |
| 21 | + "name": "my-worker", |
| 22 | + "compatibility_date": "$today", |
| 23 | + |
| 24 | + "r2_buckets": [ |
| 25 | + { |
| 26 | + "bucket_name": "screenshots-bucket", |
| 27 | + "binding": "screenshots_bucket", |
| 28 | + "experimental_remote": true, |
| 29 | + }, |
| 30 | + ], |
| 31 | +} |
| 32 | +``` |
| 33 | + |
| 34 | +</WranglerConfig> |
| 35 | + |
| 36 | +When remote bindings are configured, your Worker **still executes locally**, but all binding calls are proxied to the deployed resource that runs on Cloudflare's network. |
| 37 | + |
| 38 | +**You can try out remote bindings for local development today with:** |
| 39 | + |
| 40 | +- [Wrangler v4.20.3](/workers/development-testing/#using-wrangler-with-remote-bindings): Use the `wrangler dev --x-remote-bindings command`. |
| 41 | +- The [Cloudflare Vite Plugin](/workers/development-testing/#using-vite-with-remote-bindings): Refer to the documentation for how to enable in your Vite config. |
| 42 | +- The [Cloudflare Vitest Plugin](/workers/development-testing/#using-vitest-with-remote-bindings): Refer to the documentation for how to enable in your Vitest config. |
