## Wrangler config is optional when using Vite plugin

[Workers](https://developers.cloudflare.com/workers/)

When using the [Cloudflare Vite plugin](https://developers.cloudflare.com/workers/vite-plugin/) to build and deploy Workers, a Wrangler configuration file is now optional for assets-only (static) sites. If no `wrangler.toml`, `wrangler.json`, or `wrangler.jsonc` file is found, the plugin generates sensible defaults for an assets-only site. The `name` is based on the `package.json` or the project directory name, and the `compatibility_date` uses the latest date supported by your installed Miniflare version.

This allows easier setup for static sites using Vite. Note that SPAs will still need to [set `assets.not_found_handling` to `single-page-application` ↗︎](https://developers.cloudflare.com/workers/static-assets/routing/single-page-application/) in order to function correctly.
