// Standard variation
function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<T>
    })
}


// For the "unwrapping" variation

function api<T>(url: string): Promise<T> {
  return fetch(url)
    .then(response => {
      if (!response.ok) {
        throw new Error(response.statusText)
      }
      return response.json() as Promise<{ data: T }>
    })
    .then(data => {
        return data.data
    })
}
