Getting Started

This instructions will help you install the celebrities app in your local environment.

  1. Clone the repository with:

    $ git clone git@github.com:watson-developer-cloud/your-celebrity-match.git
  2. Install node (use v0.10.31)

  3. Install mongodb

  4. Install the npm modules:

    $ npm install

    Note: Make sure you are in the project directory, the package.json file should be visible.

  5. Start mongodb

    $ mongod

    (Run this in a separate terminal window)

  6. You need some credentials to use Twitter API, Personality Insights and MongoDC:

  • Get credentials to use Personality Insights.
  • Create a FREE Mongodb database using MongoLab.
  • Create a Twitter app and get the API credentials here.
  1. Update the Twitter, MongoDB and Personality Insights credentials in config/config.js

    mongodb: process.env.MONGODB || 'mongodb://localhost/celebs',
    
    {
      personality_insights: {
        url:      '<url>',
        username: '<username>',
        password: '<password>'
        // If your credentials have an apikey field use
        // iam_apikey: '<apikey>',
      },
    
      twitter: [{
        consumer_key:       '<consumer_key>',
        consumer_secret:    '<consumer_secret>',
        access_token_key:   '<access_token_key>',
        access_token_secret:'<access_token_secret>'
      }]
    }
  2. Start the app

    $ npm start
  3. Update the database with the celebrities by making a POST request to:

    http://localhost:3000/celebrities/syncdb

    The celebrities are not added by default. Hence the above step is recommended. Refer #Celebrities section below for more information. When running in bluemix make sure the environment variable DEMO is set to 0.

  4. You can add additional celebrities to the database as long as they are verified, have at least 10,000 followers, and have over 1,000 tweets. To add another celebrity, make a POST request to:

    http://localhost:3000/celebrities/add/@username
    

    where username is the Twitter handle of the celebrity you would like to add.

Celebrities

The application comes with two 'celebrity' profiles: @germanatt and @nfriedly. If you want to add more profiles, you have two options:

Auto-Lookup

  1. Choose a person on Twitter to include as a 'celebrity'. Ensure this person is verified, has at least 10,000 followers, and has over 1,000 tweets.

  2. Make a POST request to:

    http://localhost:3000/celebrities/add/@username
    

    where username is the Twitter handle of the celebrity you would like to add.

SyncDB

  1. Choose a person to include as a 'celebrity'. You need at least 100 different words written by that person. Blog posts, tweets, text messages, emails will work.
  2. Get the profile by using the Personality Insights service with the text you have and save the json profile in the profiles folder. Make sure the file has the .json extension as in the examples provided.
  3. Start the app and make a POST request to: http://localhost:3000/celebrities/syncdb. It will repopulate the application database and add the new profile. Be aware that this command will erase all celebrities previously added to the database.

Note: In order to add celebrities, you must not be running the app in demo mode. Either run the app locally or set the DEMO environment variable to 0 when running the app on Bluemix.
