How it works
Getting Started
This instructions will help you install the celebrities app in your local environment.

Install node (use v0.10.31)
-
Install mongodb

Install the npm modules:
$ npm install
Note: Make sure you are in the project directory, the
package.json
file should be visible. -
Start mongodb
$ mongod
(Run this in a separate terminal window)

- Create a FREE Mongodb database using MongoLab.
- Create a Twitter app and get the API credentials here.
-
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>' }, twitter: [{ consumer_key: '<consumer_key>', consumer_secret: '<consumer_secret>', access_token_key: '<access_token_key>', access_token_secret:'<access_token_secret>' }] }
-
Start the app
$ node app.js
-
Update the database with the celebrities by going to:

Personality Insights Credentials
The credentials for the services are stored in the VCAP_SERVICES environment variable. In order to get them you need to first create and bind the service to your application.
There are two ways to get the credentials, you can use Bluemix to access your app and view the VCAP_SERVICES
there or you can run:
$ cf env <application-name>
Example output:
System-Provided:
{
"VCAP_SERVICES": {
"personality_insights": [{
"credentials": {
"password": "<password>",
"url": "<url>",
"username": "<username>"
},
"label": "personality_insights",
"name": "personality-insights-service",
"plan": "IBM Watson Personality Insights Monthly Plan"
}]
}
}
You need to copy username
, password
.
Celebrities
The application comes with two profiles: @germanatt and @nfriedly. If you want to add more profiles you will have to:
- Choose a person to include as 'celebrity'. You need at least 100 different words writted by that person, blog posts, tweets, text messages, emails will work.
- 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. - Start the app and go to:
http://localhost:3000/celebrities/syncdb
. It will repopulate the application database and add the new profile.
