# clientFromNetwork

Returns the client configuration from a `StacksNetwork` object, ensuring a fetch function is always present. If the network's `client.fetch` is not set, a default fetch function is created automatically.

***

### Usage

```ts
import { clientFromNetwork, STACKS_TESTNET } from '@stacks/network';

const client = clientFromNetwork(STACKS_TESTNET);

console.log(client.baseUrl); // 'https://api.testnet.hiro.so'
console.log(typeof client.fetch); // 'function' — always defined
```

#### Notes

* This is primarily used internally by `@stacks/transactions` networking functions to ensure a fetch function is always available.
* If `network.client.fetch` is already set, it is returned as-is.
* If not set, a new default fetch function is created via `createFetchFn()` from `@stacks/common`.
