Node HTTP Module: Client

Node has a built-in HTTP module for making and responding to requests. In this training, we'll use the HTTP module to issue requests to a server.

Prerequisites

• ga-wdi-boston/node-api-promises

Objectives

By the end of this, developers should be able to:

• Make request from a Node client, similar to curl.

Preparation

1. Fork and clone this repository.
2. Install dependencies with npm install.

Lab: Read Node Client Documentation

Read the following documentation from the Node HTTP module. While reading, take note of any new concepts or vocabulary that is confusing. Pay attention to function signatures. When you're finished taking notes, research one or two points you'd like made clearer. We will discuss our findings.

• Class: http.ClientRequest
• http.request(options[, callback])

Demo: Make a Request

Start the echo server with node lib/server.js.

Make a reqeust by running node lib/request.js.

Read-Along: A Simple request

Let's read the main part of the request script, the part that uses http.request.

Lab: Compare HTTP Client with curl and AJAX

Examine the code in lib/request.js. How is it similar to curl and AJAX? How does it differ?

Annotate the code in lib/request-promises.js.
