Minor Changes

• #14013 `3cf9d0e` Thanks @jamesopstad! - Add experimental experimental.newConfig option to load the entry Worker's configuration from cloudflare.config.ts

This is an experimental, opt-in feature. When enabled, the plugin loads the entry Worker's configuration from a cloudflare.config.ts file instead of the usual wrangler.json / wrangler.jsonc / wrangler.toml.

Pass true to enable with defaults, or an object to customise behaviour. Currently the only sub-option is types.generate (defaults to true), which writes a worker-configuration.d.ts file next to the config. This enables typed env and exports for your Worker and currently assumes that you have @cloudflare/workers-types installed.

// vite.config.ts
import { defineConfig } from "vite";
import { cloudflare } from "@cloudflare/vite-plugin";

export default defineConfig({
plugins: [
cloudflare({
experimental: {
newConfig: true,
},
}),
],
});

// cloudflare.config.ts
import {
defineWorker,
bindings,
} from "@cloudflare/vite-plugin/experimental-config";
import * as entrypoint from "./src/index.ts" with { type: "cf-worker" };

export default defineWorker((ctx) => ({
name: "my-worker",
entrypoint,
compatibilityDate: "2026-05-18",
env: {
MY_TEXT: bindings.text(`The mode is ${ctx.mode}`),
MY_KV: bindings.kv(),
},
}));

A few limitations apply while the feature is experimental:

• configPath cannot be combined with experimental.newConfig. The entry Worker is always loaded from cloudflare.config.ts at the project root.
• auxiliaryWorkers are not yet supported with experimental.newConfig.

Because this is experimental, the option, the cloudflare.config.ts schema, and the @cloudflare/vite-plugin/experimental-config exports may change in any release.
