Error Handling

Every method returns a readonly [Error, null] | readonly [null, T] tuple.

const [error, data] = await client.GET('get-users')

if (error) return handleError(error)
// data is fully typed and non-null here
console.log(data)

Errors are returned (not thrown) for:

• Network failures
• Non-2xx HTTP responses
• JSON parse failures
• apiPayload Zod validation failures

Errors are thrown for:

• Missing serverUrl
• Missing Authorization header on a protected route
