```ts
type NativeFetch = typeof globalThis.fetch;
```

Defined in: [packages/common/src/Http.ts:22](https://github.com/evoluhq/evolu/blob/a18269a1b822c670b507c6a9b73b23eed32551fe/packages/common/src/Http.ts#L22)

WHATWG-fetch-compatible function used by [fetch](https://evolu.dev/docs/api-reference/common/Http/functions/fetch).

A default dependency, replaceable at the composition root — for a
platform-optimized fetch such as React Native's, a configured undici
instance, or a test double. Implementations must be pre-bound; unbound
`globalThis.fetch` throws in browsers.
