Personality insight input var nodejs - node.js

Question

var PersonalityInsightsV2 = require('watson-developer-cloud/personality-insights/v2');
var personality_insights = new PersonalityInsightsV2({
username: '<username>',
password: '<password>'
});
personality_insights.profile({
text: '<?php echo $_Session['description'];?>',
language: 'en' },
function (err, response) {
if (err)
console.log('error:', err);
else
console.log(JSON.stringify(response, null, 2));
});
It doesn't display anything. I have also done npm watson cloud and saved it, I have put my credentials and also forked it on git. What am I missing? I am a beginner but would love to use this on my page!

Answer 1

Here are the steps to run it locally, since you are a beginner I'll start from the beginning.
Create a new folder and name it whatever you want. Put these files in there.
Name the first file: index.js
fill in <YOUR-USERNAME>, <YOUR-PASSWORD>, and <YOUR-100-UNIQUE-WORDS> variables.
var express = require('express');
var app = express();
var http = require('http').Server(app);
var cfenv = require("cfenv");
var appEnv = cfenv.getAppEnv();
http.listen(appEnv.port, appEnv.bind);
var PersonalityInsightsV2 = require('watson-developer-cloud/personality-insights/v2');
var personality_insights = new PersonalityInsightsV2({
username: '<YOUR-USERNAME>',
password: '<YOUR-PASSWORD>'
});
personality_insights.profile({
text: "<YOUR-100-UNIQUE-WORDS>",
language: 'en' },
function (err, response) {
if (err)
console.log('error:', err);
else
console.log(JSON.stringify(response, null, 2));
});
Create another file and name it: package.json
put these contents in there
{
"name": "myWatsonApp",
"version": "1.0.0",
"description": "A Watson Personality Insights application",
"main": "index.js",
"scripts": {
"start": "node index.js"
},
"dependencies": {
"cfenv": "^1.0.3",
"express": "^4.13.4",
"watson-developer-cloud": "^2.2.0"
}
}
open your terminal and cd to the root of your folder you just created.
Run the command: npm install
Then run the command npm start
Your application will then be running and you will see output from the personality insights call you made in index.js
