Get Remote HTML Data And Parse It In Express For Node.js

May 18, 2015

Have you ever wanted to fetch remote HTML data in a similar fashion to cURL or Wget using some backend web service and parse it? If you said no, don’t worry, I said the exact thing until I was challenged to do so. For the challenge, I chose to use Express as my framework and a few libraries to assist in the process of fetching and parsing.

I chose to use the HTTP and HTTPS libraries for fetching the data and the htmlparser2 for parsing the HTML data. These are of course only a few of many alternatives to choose from for such a task.

Imgur is a great image service for sharing and viewing images across the internet.

Since there is a lot of buzz around AngularJS lately and there isn’t already an AngularJS extension for the Imgur REST API, I decided to take it upon myself and start creating one.

I have a few popular Oauth related posts on my blog. I have one pertaining to Oauth 1.0a, and I have one on the topic of Oauth 2.0 for use in mobile application development. However, I get a lot of requests to show how to accomplish an Oauth 2.0 connection in a web browser using only JavaScript and AngularJS.

We’re going to better explore the process flow behind Oauth 2.0 to establish a secure connection with a provider of our choice. In this particular example we’ll be using Imgur because I personally think it is a great service.

When developing web applications a common way to store data is to use local storage. This NoSQL approach is great, but what if you’re coming from an RDBMS? With HTML5, you have access to the WebSQL API which allows us to use SQL queries for handling client side storage.

This guide will show you how to use the WebSQL API, which is based around SQLite, in your web application. This information can even be extended for use with mobile hybrid applications.

I’ve still been doing a lot of fiddling with Express web framework for Node.js. I recently ran into an issue with saving data to sessions because much of the documentation online is outdated and no longer functional. However, I did get it working, and am going to discuss it in this guide.

If you’re not familiar with Express, you may want to take a moment and read my other article regarding installation.

A follower of my blog recently came to me asking for help with their Magento API service. If you’re unfamiliar with Magento, it is an Ecommerce solution by eBay that uses Oauth 1.0a to handle API requests. If you’ve been keeping up with my blog you’ll notice I had done a previous post on Oauth 1.0a, and it was everything, but fun.

So how does a newbie go about making quick tests to Oauth providers or RESTful APIs without a lot of stress? If you’re using Google Chrome like I am, there is a nifty application called Postman which does very thorough API testing.

If you’ve been keeping up with my work, you’ll remember in 2014 I released an app called OTP Safe for Android and iOS. This was a hybrid application created with Ionic Framework, that manages time-based one-time passwords (TOTP) commonly used for two-factor authentication (2FA).

I’m starting 2015 off with a bang by releasing my first ever Google Chrome extension. OTP Safe for Chrome was designed to mimic the functionality of the iOS and Android versions, but for laptop and desktop computers.
