node-es6-request

HTTP Request library written in ES6 for Node.js

Installation

npm install es6-request --save

API

Functions that return a new Request instance:

• es6-request.get(url)
• es6-request.put(url)
• es6-request.post(url)
• es6-request.head(url)
• es6-request.patch(url)
• es6-request.delete(url)
• es6-request.options(url)

Request

Request.query(key/object, val)

Can be called with only one object as argument, or two arguments (key and value). This function adds to the query string of the url or creates a new query string that will be added to the url before performing the reuqest.

Request.header(key, val)

Adds a header to the request by the name of key and the content of val.

Request.headers(object)

Adds headers from a key/value object.

Request.options(object)

Adds options from a key/value object to the Node.js HTTP options.

Request.option(key, val)

Adds an option to the Node.js HTTP options.

Request.json(object)

Translates the object into a key/value string and sends the request as x-www-form-urlencoded.

Request.write(chunk[, encoding][, callback])

You must run Request.start() before running this function. Directly writes to the request using this function from Node.js.

Request.send(chunk[, encoding][, callback])

Starts a request, then directly writes to the it using this function from Node.js, then performs the request.

Request.start()

Starts a request. After this function has been called, helper functions like Request.headers(), Request.header() and Request.query() will no longer work until the request has ended.

Request.pipe(destination)

Starts the request if it is not already started. Pipes the response chunks to the destination stream using this function from Node.js, then performs the request.

Request.perform()

This function ends a request. It is called by other functions like Request.send() and Request.pipe(). This function returns a Promise.

Usage

Simple GET Request

const request = require("es6-request");

// you can exchange "get" with "head", "delete" or "options" here
// they all have the exact same API
request.get("https://raw.githubusercontent.com/alexrsagen/node-es6-request/master/README.md")
.then((body) => {
    console.log(body);
    // should output this README file!
});

POST Request

The following example will send a x-www-form-urlencoded request to the server containing keys and values from the json object.

const request = require("es6-request");

// you can exchange "post" with either "put" or "patch" here
// they all have the exact same API
request.post("http://api.somewebsite.com/endpoint")
.json({somekey: "somevalue"})
.then((body) => {
    // ...
});

This example will send a raw string to the server.

const request = require("es6-request");

// you can exchange "post" with either "put" or "patch" here
// they all have the exact same API
request.post("http://api.somewebsite.com/endpoint")
.send("i am a string, i will be sent to the server with a POST request.")
.then((body) => {
    // ...
});

Query string

This works the same way with any other request type.

const request = require("es6-request");

// sends a GET request to http://api.somewebsite.com/endpoint?this=that&one=two&three=four
request.get("http://api.somewebsite.com/endpoint")
.query("this", "that")
.query({
    "one": "two",
    "three": "four"
})
.then((body) => {
    // ...
});

Headers

const request = require("es6-request");

// Sends a GET request with these headers:
// {
//     "Accept": "application/json",
//     "Header-Name": "header value",
//     "Another-Header": "another value"
// }
request.get("http://api.somewebsite.com/endpoint");
.header("Accept", "application/json")
.headers({
    "Header-Name": "header value",
    "Another-Header": "another value"
})
.then(([body, res]) => {
    console.log(res.headers);
    // ...
});

Pipes

The following example POSTs all data you enter to STDIN to the local server we create, which then logs the data back to the console.

const request = require("es6-request");
const server = require("http").createServer((req, res) => {
  req.setEncoding('utf8');
  req.on('data', (chunk) => {
    console.log(chunk);
  });
  req.on('end', () => {
    res.end();
  });
}).listen(1337);

process.stdin.pipe(request.post("http://localhost:1337"));

This example pipes the GitHub logo to a file named logo.png.

const request = require("es6-request");
const fs = require("fs");

request.get("https://github.com/images/modules/logos_page/GitHub-Mark.png").pipe(fs.createWriteStream("logo.png")).perform();
