npm package: @lcluber/aiasjs
Description: Promise and observable based HTTP client (Ajax) library
Author: Ludovic Cluber
Latest version: 3.2.1

## Synopsis

Aias.js is an open source promise and observable based HTTP client ES6 library.
It includes features like "audiobuffer" response type, comprehensive error handling and logging.

## Motivation

The main purpose of this library is to provide a simple tool for sending asynchronous HTTP (Ajax) requests.

## Installation

### NPM

```bash
$ npm install @lcluber/aiasjs
```

### Yarn

```bash
$ yarn add @lcluber/aiasjs
```

## Usage

### ES6

```javascript
import { HTTP } from "@lcluber/aiasjs";

const scientist = {
  firstname: "Galileo",
  lastname: "Galilei",
  born: 1564,
  died: 1642
};

// Set headers globally
HTTP.setHeaders("POST", { "Content-Type": "application/json" }); // Default setting for POST requests
HTTP.setHeaders("GET", { "Content-Type": "application/x-www-form-urlencoded" }); // Default setting for GET requests

// example for authorization headers :
var bearer = `Bearer ${token}`; // where token is your json web token 
HTTP.setHeaders("GET", { Authorization: bearer });
HTTP.setHeaders("POST", { Authorization: bearer });
HTTP.setHeaders("PATCH", { Authorization: bearer });
HTTP.setHeaders("PUT", { Authorization: bearer });

// Using promises

// POST request using promise
HTTP.promise.post("http://url.com/api/scientists", "json", scientist)
  .then(response => {
    console.log(response);
  })
  .catch(err => {
    console.log("error", err);
  });

// GET request using promise
HTTP.promise.get("http://url.com/api/scientists/2", "json")
  .then(response => {
    console.log(response);
  })
  .catch(err => {
    console.log("error", err);
  });

// GET request using observable
HTTP.observable.get("http://url.com/api/scientists/2", "json").subscribe(
  response => {
    console.log(response);
  },
  err => console.log("error", err)
);

// POST request with multipart/form-data
HTTP.observable.post(`${environment.api}post/img`, 
                          'json',
                          imgFile, // the file as FormData
                          { "Content-Type": '' } // set headers only for this request. Set to '' to delete a property set in global headers.
                    ).subscribe(
  response => {
    console.log(response);
  },
  err => console.log("error", err)
); 

```
