svix-fetch

svix-fetch (v4.0.0) is a fork of isomorphic-fetch that adds HTTP keep-alive support in Node.js. It is an isomorphic WHATWG Fetch API polyfill for Node.js and browserify. The package is maintained by Svix for internal use and published publicly. It requires explicit installation of the `fetch` polyfill and is only suitable for projects needing the specific keepalive behavior; otherwise, alternatives like isomorphic-fetch or cross-fetch are recommended. Maintenance is minimal.
