## APIs
### ``
#### Props
| Name | Type | Required | Description |
| ---------- | ----------------------------------------------------------------------- | -------- | -------------------------------------------------------------------------------- |
| `promise` | `() => Promise` | ✓ | A function returning a promise (it will be called when the component is mounted) |
| `initial` | `Value` (the same type with the value what the promise should resolves) | | An initial value |
| `children` | `(snapshot: Snapshot) => ReactNode` | | A render props function |
#### Snapshot
`` receives children as a render-props pattern function that gives a snapshot object which has the shape like the following:
| Name | Type | Description |
| -------------- | ------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- |
| `status` | `"PENDING"`, `"FULFILLED"` or `"REJECTED"` | The promise's status. In TypeScript you can use `Status` enum instead of string enum |
| `value` | `Value` (the value what the promise resolves) or `null` | The value what the promise resolves. When `status` is `"PENDING"` or `"REJECTED"` and `props.initial` is not given, this is `null` |
| `error` | `Error` or `null` | The error when the promise rejects. This is `null` if `status` is not `"REJECTED"` |
| `isLoading` | `boolean` | A short hand value whether the promise's status is `"PENDING"` or not (same with to `status === "PENDING"`). |
| `requireValue` | `Value` (the value what the promise resolves) | Same as `value` but it throws an error if `value` is `null` |
#### Usage
```jsx
import Repromised from 'repromised';
const SearchResult = ({ query }) => (
fetchByQuery(query)} initial={[]} key={query}>
{snapshot => snapshot.isLoading
?
:
{snapshot.value.map(result => )}
}
);
```
