tw-custserv

Problem Statement

Write a simple Twitter API client in Haskell. This client simply has to fetch and display Tweets that:

• Have been re-Tweeted at least once and
• Contain the hashtag #custserv

Using the application

• First, you must obtain consumer key and secret from Twitter Application Management page, and you have to set those values to the config json:

• Create an application (fill in dummy data to the provided form)

• Now you must prepare OAuth access token and secret

• Under Key and Access Tokens tab. You will have Application Setting and Your access token generete them

• Create a config.json file with the above details (sample given below).

  {
    "apiKey": "<Consumer Key (API Key) in Application Setting>",
    "apiSecret": "<Consumer Secret (API Secret) in Application Setting>",
    "accessToken": "<Access Token in Your Access Token>",
    "accessTokenSecret": "<Access Token Secret in Your Access Token>"
  }

• Run stack build (you may need to run stack setup as well)

• Run stack exec tw-custserv-exe

About the code

• It is a stack project so all the things specific to stack apply here as well.
• src/Types contain all the custom types.
  • Config.hs: the configuration object used to authenticate.
  • Query.hs: the query object (extend it if you want more functionality from queries)
  • Tweets.hs: Representation of a Tweet, Metadata accompnying a search query and The complete search response by twitter
• src/TwitterAuth.hs contains all the Oauth related functions.
• src/TwitterCustServ.hs contains everythig else.

Imprvement

• User should be able to login with their credentials and not have to setup the config.json
