How to create a custom styled twitter feed for your website

Posted written by Paul Seal on February 05, 2016 Tips

In this tutorial I show you how to create your own custom twitter feed for your website. You will have full control over the styling of the feed, like the one I have on my about page. It also pulls through the follower count.
A lot of clients ask for this as they don't like the default styling of the twitter feed plugin.

This tutorial is meant for an MVC website with .NET 4.5 which makes it suitable for Umbraco too.

I've included some functions to help with formatting the tweets and a function to get the relative time since the tweet.

If you already have your twitter API keys you can skip to number 4.

Before you start, you need to have the twitter API keys. To get these, you need to:

  1. sign in to https://apps.twitter.com/ with your twitter account.

  2. Click on the Create New App button and fill out the details. I didn't enter a Callback URL.
    Here's what I put for my site

    If you haven't done already, it will tell you that you need to add your mobile phone number to your twitter profile in the settings part of the main twitter site. I added my mobile number and unticked 'Let others find me by my mobile number' in the Security and privacy tab.

  3. When you have created your app and click on the name to go into the application management screen, you need to click on the tab named Keys and Access Tokens. You will need to copy your Consumer Key and your Consumer Secret. I put these as app settings in my website. You shouldn't have them in your code.

  4. Next you need to add the Skybrud.Social dll to your project. You can install it by using Package Manager Console. 

    PM> Install-Package Skybrud.Social
    If you don't use package manager, you can visit the Skybrud.Social site here http://social.skybrud.dk/

  5. Add a reference to System.Runtime.Caching to your project, because the code I wrote uses caching to reduce the calls to the twitter API.

  6. Add the following code to a partial or a view. I've put it all in one for convenience and for the purpose of this tutorial. Normally I would be passing the collection of tweets in to the model for the view. Also I would have the functions in a class elsewhere but it is very handy for this tutorial and easy for you to get something working.

    @using Skybrud.Social.Twitter
    @using Skybrud.Social.Twitter.Entities
    @using Skybrud.Social.Twitter.OAuth
    @using Skybrud.Social.Twitter.Objects
    @using System.Web.Configuration
    @using System.Runtime.Caching
    @using System.Text.RegularExpressions

    @{
       //get the twitter api keys from the web.config file.
       string consumerKey = WebConfigurationManager.AppSettings["TwitterAPIConsumerKey"];
       string consumerSecret = WebConfigurationManager.AppSettings["TwitterAPIConsumerSecret"];
       string twitterUserName = WebConfigurationManager.AppSettings["TwitterUsername"];
       const int TWITTER_FEED_CACHING_TIME_IN_MINUTES = 10;
       const int NUMBER_OF_TWEETS_TO_SHOW = 3;
       const string TWITTER_DOMAIN_URL = "https://twitter.com/";

       var tweets = GetTweets(consumerKey, consumerSecret, twitterUserName, TWITTER_FEED_CACHING_TIME_IN_MINUTES).Take(NUMBER_OF_TWEETS_TO_SHOW);
    }

    @*These are the styles I used for mine, you can create your own*@
