comlink-fetch

library0.1.2jsnpmunverified

Comlink Fetch is a minimal ES6 wrapper that integrates the native Fetch API with Comlink, enabling fetch calls to be offloaded to a Web Worker for improved UI performance. Current stable version: 0.1.2. Release cadence is low (single initial release). It differentiates by providing a zero-config proxy that allows fetch to be used transparently within workers, unlike manual message passing. Only supports default import, no named exports. Note: Package is experimental and no longer actively maintained.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

comlinkFetch

✓ import comlinkFetch from 'comlink-fetch'

✗ const comlinkFetch = require('comlink-fetch')

Package is ESM-only; no CommonJS support.

default import

✓ import comlinkFetch from 'comlink-fetch'

✗ import { comlinkFetch } from 'comlink-fetch'

Only a default export; named export causes undefined.

TypeScript usage

✓ import comlinkFetch from 'comlink-fetch'

✗ import * as comlinkFetch from 'comlink-fetch'

No type definitions shipped. Use @ts-ignore or custom typings.

Shows basic usage: wrap a worker with Comlink and perform fetch inside the worker.

// main.js import { wrap } from 'comlink'; import comlinkFetch from 'comlink-fetch'; async function init() { const worker = new Worker('worker.js'); const api = wrap(worker); // comlinkFetch is used inside the worker // See worker.js below } // worker.js importScripts('https://unpkg.com/comlink@4/umd/comlink.js'); importScripts('https://unpkg.com/comlink-fetch/dist/comlink-fetch.umd.js'); const fetchWorker = { async get(url) { const response = await fetch(url); return response.json(); } }; Comlink.expose(fetchWorker);

Known issues

deprecatedPackage is no longer maintained; last publish 4 years ago.

fix

Use native fetch in workers directly (modern browsers support it) or use Comlink with explicit fetch.

affects: *

gotchaImport must be default import; named import results in undefined.

fix

Use `import comlinkFetch from 'comlink-fetch'`

affects: >=0.1

gotchaPackage only ships UMD bundle for workers; not ESM for modern bundlers.

fix

For bundler usage, consider using dynamic import or fork the package.

affects: >=0.1

breakingComlink v4 changed API; comlink-fetch may be incompatible with newer versions.

fix

Pin comlink to version 3 or use a more recent Comlink wrapper.

affects: >=0.1
