The following app is deployed on IBM Cloud but I only have a lite account so odds are I will have terminated it.
Here is the URL:
https://henry-645-sentiment-analyzer-proud-crane-hr.mybluemix.net/
To run locally
contact me for the Watson api key and URL
create and .env file in ..../IBM-Watson-NLU-Interface/sentimentAnalyzerServer
API_KEY=<key>
API_URL=<URL>
Set directory to Server
cd ..../IBM-Watson-NLU-Interface/sentimentAnalyzerServer
install dependencies
npm install
Set directory to Client
cd ..../IBM-Watson-NLU-Interface/sentimentAnalyzerClient
install dependencies
npm install
run build script
npm run-script build
Set directory to Server
cd ..../IBM-Watson-NLU-Interface/sentimentAnalyzerServer
start app
npm start
This will run the app on localhost:8080
Have FUN!
