ERROR Could not resolve "cloudflare:workers"

Refactoring our working WebSockets to use Durable Objects with RPC methods. Using the Durable Object sample to start with no errors or warnings. But on build: ✘ [ERROR] Could not resolve "cloudflare:workers" src/durable-objects/testws.do.ts:3:30: 3 │ import { DurableObject } from 'cloudflare:workers' [@Cloudflare/workers-types 4.2 node v20.17.0 npm 10.8.2 ] Not sure if this is a package problem or config issue or what.. TIA for any direction

No idea how that devDependency got messed up. Fixed that. updated to ⛅️ wrangler 3.75.0 same: ✘ [ERROR] Could not resolve "cloudflare:workers" That was it! Mad at myself for not trusting the error handling message. Had to play with DO migrations a bit, but now have a new DO to build out our new WS connection. Very exciting. Thank you Skye - this was a major roadblock. Should have asked sooner.

How do we satisfy eslint with this import? Is there a cloudflare template that has eslint set up that demonstrates? eslint doesn't know how to resolve cloudflare:workers, so it complains about import { DurableObject } from "cloudflare:workers";. I just shut it off though and things seem to work fine:

// eslint-disable-next-line import/no-unresolved
import { DurableObject } from "cloudflare:workers";

// eslint-disable-next-line import/no-unresolved
import { DurableObject } from "cloudflare:workers";

Hey 👋 Same issue here, with "@cloudflare/workers-types to 4.20241022.0 (and set to same date in tsconfig: compilerOptions.types -> @cloudflare/workers-types/2024-10-22) + wrangler latest version, I get Cannot find module '@cloudflare:workers' or its corresponding type declarations. in my editor 🤔

OKay it's working ,I had a typo in the code It's cloudflare:workers not @Cloudflare:workers

mr nooli•2mo ago

exact same issue for me:

    src/durable-object.ts:2:30:
      2 │ import { DurableObject } from "cloudflare:workers";

    src/durable-object.ts:2:30:
      2 │ import { DurableObject } from "cloudflare:workers";

wondering the same

same.. using @hono-rate-limiter/cloudflare setting in vite doesn't help either:

ssr: {
    resolve: {
        conditions: ['workerd', 'worker', 'browser'],
    },
    external: ['cloudflare:workers'],
},

ssr: {
    resolve: {
        conditions: ['workerd', 'worker', 'browser'],
    },
    external: ['cloudflare:workers'],
},

Has anyone managed to solve this error with Vite? I use Hono with its Cloudflare dev server. My vite config looks like this, but I still get the same error that "cloudflare:workers" could not be resolved:

import build from '@hono/vite-build/cloudflare-workers';
import devServer from '@hono/vite-dev-server';
import cloudflareAdapter from '@hono/vite-dev-server/cloudflare';
import { defineConfig } from 'vite';

export default defineConfig(() => {
  return {
    build: {
      minify: false,
      rollupOptions: {
        output: {
          entryFileNames: '_worker.js',
        },
        external: ['cloudflare:workers'],
      },
    },
    plugins: [
      devServer({
        adapter: cloudflareAdapter,
        entry: './src/index.tsx',                
      }),
      build(),
    ],
  };
});

import build from '@hono/vite-build/cloudflare-workers';
import devServer from '@hono/vite-dev-server';
import cloudflareAdapter from '@hono/vite-dev-server/cloudflare';
import { defineConfig } from 'vite';

export default defineConfig(() => {
  return {
    build: {
      minify: false,
      rollupOptions: {
        output: {
          entryFileNames: '_worker.js',
        },
        external: ['cloudflare:workers'],
      },
    },
    plugins: [
      devServer({
        adapter: cloudflareAdapter,
        entry: './src/index.tsx',                
      }),
      build(),
    ],
  };
});
