# ASIS
A small utility library to handle JSON encoded http responses easily, transforms the response into an internal type of data and extends the capabilities of `Response`, `Iterable`, `List`, `Future`, `Future`, `Future` to handle data manipulation on the same future chain.
## Getting Started
This package built upon the [http](https://pub.dev/packages/http) package to work with it's internal [Response](https://pub.dev/documentation/http/latest/http/Response-class.html) type.
It's also possible to use some of the internal features without depending to [http](https://pub.dev/packages/http) package, such as the extensions, `Future>`, `Future>`, that helps to manipulate the data on the same future chain.
## Example
Here is a working example that shows the brief functionality of the library, this example highlights how to transform the JSON encoded HTTP body to an internal custom object and a list of that custom object on top of some data manipulation without leaving the same future chain that get's the data from the http call.
```dart
import 'package:http/http.dart' as http;
import 'package:asis/asis.dart';
class Task {
final int userId;
final int id;
final String title;
final bool completed;
// Task({this.userId, this.id, this.title, this.completed});
Task.fromJson(Map e)
: userId = e['userId'],
id = e['id'],
title = e['title'],
completed = e['completed'];
/// Static method to pass the handler directly to the input.
static Task handler(Map e) {
return Task.fromJson(e);
}
}
/// Resource url.
var url = 'http://jsonplaceholder.typicode.com/todos';
/// Returns a task object.
Future task(int id) => http.get('$url/$id').as(Task.handler);
/// Returns a list of tasks.
Future> get tasks => http.get(url).asList(Task.handler);
void main() async {
/// Get the third task and print the title.
task(3)
.then((e) => e.title)
.then((e) => 'Title of the third task: $e')
.then(print);
/// Print the title of the top 3 task.
tasks.take(3).each((e) => print(e.title));
/// Count of the completed tasks.
tasks
.where((e) => e.completed)
.fold(0, (p, _) => p + 1)
.then((e) => 'Number of the completed tasks: $e')
.then(print);
}
```
