 - `npm run build:worker`: Runs the [@opennextjs/cloudflare](https://www.npmjs.com/package/@opennextjs/cloudflare) adapter. This first builds your app by running `next build` behind the scenes, and then transforms the build output to a format that you can run locally using [Wrangler](/workers/wrangler/) and deploy to Cloudflare.
 - `npm run dev:worker`: Takes the output generated by `build:worker` and runs it locally in [workerd](https://github.com/cloudflare/workerd), the open-source Workers Runtime, allowing you to run the app locally in the same environment that it will run in production. If you instead run `next dev`, your app will run in Node.js, which is a different JavaScript runtime from the Workers runtime, with differences in behavior and APIs.
-- `npm run preview:worker`: Runs `build:worker` and then `preview:worker`, allowing you to quickly preview your app running locally in the Workers runtime, via a single command.
