Manage Workers KV using Wrangler.

kv namespace

Manage Workers KV namespaces.

Note

The kv ... commands allow you to manage your Workers KV resources in the Cloudflare network. Learn more about using Workers KV with Wrangler in the Workers KV guide.

Caution

Since version 3.60.0, Wrangler supports the kv ... syntax. If you are using versions below 3.60.0, the command follows the kv:... syntax. Learn more about the deprecation of the kv:... syntax in the Wrangler commands for KV page.

kv namespace create

Create a new namespace

npx wrangler kv namespace create <NAMESPACE>
yarn wrangler kv namespace create <NAMESPACE>
pnpm wrangler kv namespace create <NAMESPACE>

  • <NAMESPACE> string required

    The name of the new namespace

  • --preview boolean

    Interact with a preview namespace

  • --jurisdiction string

    The jurisdiction where the new namespace will be created (e.g. "us", "eu", "fedramp")

  • --use-remote boolean

    Use a remote binding when adding the newly created resource to your config

  • --update-config boolean

    Automatically update your config file with the newly added resource

  • --binding string

    The binding name of this resource in your Worker

To restrict where a namespace durably stores data, specify --jurisdiction when creating it. Refer to Data location for supported jurisdictions.

KV Instant namespaces

Note

Workers KV Instant is currently in private beta. To enroll, contact your Cloudflare account team or sign up and tell us about your use case.

To create a Workers KV Instant namespace, pass --experimental-mode instant. This example creates a namespace named APP_CONFIG for small, infrequently updated configuration:

npx wrangler@latest kv namespace create APP_CONFIG --experimental-mode instant
yarn wrangler@latest kv namespace create APP_CONFIG --experimental-mode instant
pnpm wrangler@latest kv namespace create APP_CONFIG --experimental-mode instant

You can also use the --x-mode instant alias.
