How to Install

npm install azure-cognitiveservices-textanalytics

How to use

Create a Cognitive Services Account(ex. Text Analytics)

  const msRestAzure = require('ms-rest-azure');
  const CognitiveServicesManagement = require("azure-arm-cognitiveservices");
  let client;
  let createAccount = msRestAzure.interactiveLogin().then((credentials) => {
    client = new CognitiveServicesManagement(credentials, suite.subscriptionId);
    return client.accounts.create('groupname', 'accountname', {
      sku: {
        name: "F0"
      },
      kind: "TextAnalytics",
      location: "westus",
      properties: {}
    });
  }).catch((err) => {
    console.log('An error ocurred');
    console.dir(err, {depth: null, colors: true});
  });

List the keys from the created account

  let serviceKey;
  createAccount.then((result) => {
    return client.accounts.listKeys('groupname', 'accountname');
  }).then((result) => {
    serviceKey = result.key1;
    console.log(result.key2);
  }).catch((err) => {
    console.log('An error ocurred');
    console.dir(err, {depth: null, colors: true});
  });

Create credentials

const CognitiveServicesCredentials = require('ms-rest-azure').CognitiveServicesCredentials;

// Creating the Cognitive Services credentials
// This requires a key corresponding to the service being used (i.e. text-analytics, etc)
let credentials = new CognitiveServicesCredentials(serviceKey);

Text Analytics API

const TextAnalyticsAPIClient = require('azure-cognitiveservices-textanalytics');

let client = new TextAnalyticsAPIClient(credentials);
let input = {
   documents: [
       {
       'id': "1",
       'text': "I had a wonderful experience! The rooms were wonderful and the staff was helpful."
       }
   ]
}
let operation = client.detectLanguage(input)
operation.then(function (result){
  console.log(result.documents[0].detectedLanguages[0].name);
  console.log(result.documents[0].detectedLanguages[0].score);
}).catch(function (err){
  throw err;
});
