## README

# Observer
A Promise-like observer to resolve data multiple times.

# Installation
`flk install @flk/observer`

OR 

`npm i @flk/observer`

OR 

`yarn add @flk/observer`

# Usage

It works exactly same as [Promises](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) but with an extra thing, you can trigger multiple `resolve` or `reject` callbacks.


# Example

```js

let observer = new Observer((resolve, reject) => {
  resolve(12); // then method callback will be called

  setTimeout(() => {
    resolve({
      name: 'Hasan',
    }); // then method callback will be called again
  }, 1000);
});

observer.then(data => {
  console.log(data);
});
```

# Usage outside Falak Framework

Just import it as a normal library using `import` or `require syntax`

```js
let Observer = require('@flk/observer');

let promiser = new Observer(...);
```
