Micro Promise based HTTP client for the browser and node.js

## ✨ Features

- Make [XMLHttpRequests](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest) from the browser
- Make [http](http://nodejs.org/api/http.html) requests from node.js
- Supports the [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) API
- Built in [TypeScript](https://www.typescriptlang.org/) support

## 👍🏻 Browser Support

### NOTE

If you intend to support Internet Explorer, be sure to have a [poly-fill](https://github.com/taylorhakes/promise-polyfill) that adds a global `Promise` object

## 🏗 Installing

Using npm:

```bash
$ npm install regrest
```

Using cdn:

```html
<script src="https://unpkg.com/regrest/build/regrest.min.js"></script>
```

## 🎬 Example

Regrest is designed to be the simplest way possible to make http calls

Performing a `GET` request

```js
// Import using Node or CommonJS module
const regrest = require("regrest");
// Or using ES6 module, also work for TypeScript
import regrest from "regrest"

// Use Promise
regrest
  .get("/man/bear/pig")
  // Print the raw response string
  .then(response => console.log(response.text))
  // Print any error if occurred
  .catch(error => console.log(`*** Error: ${error}`));

// Or use the new async/await keywords
const getGoogle = async () => {
  try {
    // Store the response in a variable
    const response = await regrest.get("/foo/bar.json");
    // print out the parsed response
    console.log(response.json);
  } catch (error) {
    // Print any error if occurred
    console.log(`*** Error: ${error}`);
  }
};

getGoogle();

// Or use callbacks
// WE DON'T DO THAT HERE
```

Performing a `POST` request

```js
regrest
  .post("/comment", JSON.stringify({ name: "Foo", comment: "Bar" }))
  .then(response => console.log(response.status, response.statusText))
  .catch(error => console.log(error));
```

## 📚 Documentation

### Convenience methods

##### regrest.request(config)

##### regrest.get(url[, config])

##### regrest.head(url[, config])

##### regrest.post(url[, data[, config]])

##### regrest.put(url[, data[, config]])

##### regrest.delete(url[, config])

##### regrest.options(url[, config])

##### regrest.patch(url[, data[, config]])

### Config options

```js
// Default options are marked with *
const config = {
  method: "GET", // *GET, POST, PUT, DELETE, etc.
  url: "https://some-domain.com/api/",
  headers: { "Content-Type": "application/json; charset=utf-8" }, // *{}
  params: { UID: 9873 },
  data: JSON.stringify(data) // *null
  maxRedirects: 10 // *5
};
```

### Response object attributes

```js
{
  // Contains the status code of the response, e.g. 404 for a not found resource, 200 for a success
  status: 200,
  // A message related to the status attribute, e.g. OK for a status 200
  statusText: "OK",
  // The headers that the server responded with
  headers: {},
  // Response content as a string
  text: "",
  // Response content as JSON
  json: {}
};
```

### Errors handling

```js
regrest.get("/McNullington").catch(error => {
  if (error.response) {
    // A request was made
    // Server responded with status call out of the 200 - 400 range
    console.log(error.response.status);
    console.log(error.response.statusText);
    console.log(error.response.headers);
    console.log(error.response.text);
    console.log(error.response.json);
  } else if (error.request) {
    // A request was made, but no response was received
  } else {
    // Something else happened
    console.log(error.message);
  }
});
```
