npx wrangler init -y .
Need to install the following packages:

✨ Types written to worker-configuration.d.ts
Action required Migrate from @cloudflare/workers-types to generated runtime types
`wrangler types` now generates runtime types and supersedes @cloudflare/workers-types.
You should now uninstall @cloudflare/workers-types and remove it from your tsconfig.json.
Action required Install @types/node
Since you have the `nodejs_compat` flag, you should install Node.js types by running "npm i --save-dev @types/node".

📣 Remember to rerun 'wrangler types' after you change your wrangler.json file.
