# Local development

Test changes to your [dynamic dispatch Worker](https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/how-workers-for-platforms-works/#dynamic-dispatch-worker) by running the dynamic dispatch Worker locally but connecting it to user Workers that have been deployed to Cloudflare.

Note

Consider using a staging namespace to test changes safely before deploying to production.

This is helpful when:

* **Testing routing changes** and validating that updates continue to work with deployed User Workers
* **Adding new middleware** like authentication, rate limiting, or logging to the dynamic dispatch Worker
* **Debugging issues** in the dynamic dispatcher that may be impacting deployed User Workers

### How to use remote dispatch namespaces

In the dynamic dispatch Worker's Wrangler file, configure the [dispatch namespace binding](https://developers.cloudflare.com/workers/wrangler/configuration/#dispatch-namespace-bindings-workers-for-platforms) to connect to the remote namespace by setting [remote = true](https://developers.cloudflare.com/workers/development-testing/#remote-bindings):

* [  wrangler.jsonc ](#tab-panel-4806)
* [  wrangler.toml ](#tab-panel-4807)

JSONC

```

{

  "dispatch_namespaces": [

    {

      "binding": "DISPATCH_NAMESPACE",

      "namespace": "production",

      "remote": true

    }

  ]

}


```

TOML

```

[[dispatch_namespaces]]

binding = "DISPATCH_NAMESPACE"

namespace = "production"

remote = true


```

This tells your dispatch Worker that's running locally to connect to the remote `production` namespace. When you run `wrangler dev`, your Dispatch Worker will route requests to the User Workers deployed in that namespace.

For more information about remote bindings during local development, refer to [remote bindings documentation](https://developers.cloudflare.com/workers/development-testing/#remote-bindings).
