Rx-Http-Request

The world-famous HTTP client Request now RxJS compliant, wrote in full Typescript | ES6 for client and server side.

Rx-Http-Request

Installation

$ npm install --save @akanass/rx-http-request rxjs

or

$ yarn add @akanass/rx-http-request rxjs

Super simple to use

Rx-Http-Request is designed to be the simplest way possible to make http calls.

It's fully Typescript | ES6 wrotten so you can import it :

import {RxHR} from "@akanass/rx-http-request";

or use CommonJS:

const RxHR = require('@akanass/rx-http-request').RxHR;

Now, it's easy to perform a HTTP request:

RxHR.get('http://www.google.fr').subscribe(
    (data) => {

        if (data.response.statusCode === 200) {
            console.log(data.body); // Show the HTML for the Google homepage.
        }
    },
    (err) => console.error(err) // Show error in console
);

Browser compatibility

Rx-Http-Request can be used in your favorite browser to have all features in your own front application.

Just import browser/index.js script and enjoy:

<script src="node_modules/@akanass/rx-http-request/browser/index.js" type="application/javascript"></script>
<script type="application/javascript">
    const RxHR = rhr.RxHR;
    
    RxHR.get('http://www.google.fr').subscribe(
        function(data){
    
            if (data.response.statusCode === 200) {
                console.log(data.body); // Show the HTML for the Google homepage.
            }
        },
        function(err){
            console.error(err) // Show error in console
        }
    );
</script>

Browser version is a standalone version so you just need to copy/paste file from node_modules/@akanass/rx-http-request/browser/index.js when you want to create your bundle and change path to it.

Build your project with Webpack

If you want to include this library inside a project builds with webpack for a client application, you must add this configuration inside your webpack configuration:

{
    target: "web",
    node: {
        fs: "empty",
        net: "empty",
        tls: "empty"
    }
}

For a server application, target will be node, node block in configuration doesn't exist and uglify plugin must be disabled.

API in Detail

Rx-Http-Request uses Request API to perform calls and returns RxJS.Observable.

All options to pass to API methods can be found here.

All methods to execute on response object can be found here.

`.request`

Returns the original Request API to perform calls without RxJS.Observable response but with a callback method.

import {RxHR} from '@akanass/rx-http-request';

RxHR.request({uri: 'http://www.google.fr'}, (error, response, body) => {

    if (!error && response.statusCode == 200) {
        console.log(body); // Show the HTML for the Google homepage.
    }
});

`.defaults(options)`

This method returns a wrapper around the normal Rx-Http-Request API that defaults to whatever options you pass to it.

Parameters:

options (required): Original Request options object with default values foreach next requests

Response:

new RxHttpRequest instance

Note: RxHR.defaults() does not modify the global API; instead, it returns a wrapper that has your default settings applied to it.

Note: You can call .defaults() on the wrapper that is returned from RxHR.defaults() to add/override defaults that were previously defaulted.

For example:

// requests using baseRequest will set the 'x-token' header
const baseRequest = RxHR.defaults({
    headers: {'x-token': 'my-token'}
});

// requests using specialRequest will include the 'x-token' header set in
// baseRequest and will also include the 'special' header
const specialRequest = baseRequest.defaults({
    headers: {special: 'special value'}
});

`.get(uri[, options])`

Performs a request with get http method.

Parameters:

uri (required): The uri where request will be performed

options (optional): Original Request options object

Response:

RxJS.Observable instance

Crawl a webpage

import {RxHR} from '@akanass/rx-http-request';

RxHR.get('http://www.google.fr').subscribe(
    (data) => {

        if (data.response.statusCode === 200) {
            console.log(data.body); // Show the HTML for the Google homepage.
        }
    },
    (err) => console.error(err) // Show error in console
);

GET something from a JSON REST API

import {RxHR} from '@akanass/rx-http-request';

const options = {
    qs: {
        access_token: 'xxxxx xxxxx' // -> uri + '?access_token=xxxxx%20xxxxx'
    },
    headers: {
        'User-Agent': 'Rx-Http-Request'
    },
    json: true // Automatically parses the JSON string in the response
};

RxHR.get('https://api.github.com/user/repos', options).subscribe(
    (data) => {

        if (data.response.statusCode === 200) {
            console.log(data.body); // Show the JSON response object.
        }
    },
    (err) => console.error(err) // Show error in console
);

`.getBuffer(uri[, options])`

Parameters:

uri (required): The uri where request will be performed

    (data) => {

        if (data.response.statusCode === 200) {
            console.log(data.response.headers['content-type']); // Show image content-type.
            console.log(data.body); // Show image buffer array.
        }
    },
    (err) => console.error(err) // Show error in console
