Installation

Install jev-hooks from npm:

npm install jev-hooks

Or use your preferred package manager:

pnpm add jev-hooks

bun add jev-hooks

React applications#

Use React 18.2+ or 19 and import hooks from jev-hooks/react. If React is not already installed:

npm install jev-hooks react react-dom

Follow the React quickstart for a complete example without an API key.

Backend programs#

Use Node.js 24+ and import from jev-hooks. React is optional and is not required for server-only applications.

See backend programs for run(), typed judgments and inference passes.

Hosting integrations#

• Next.js / Vercel: a server route and browser client.
• Cloudflare Workers: an AI binding and Worker endpoint.

Provider credentials stay on the server. Choose a provider independently of your hosting platform.
