Personality insight input var nodejs

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!

Solution

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
