🚀 Tone Analyzer Sample Application

This Node.js app demonstrates some of the Tone Analyzer service features.

Travis semantic-release

The IBM Watson Tone Analyzer service is a cognitive linguistic analysis service that detects 7 tones which are most commonly used to detect the tone of written text. These are: anger, fear, joy, sadness, confident, analytical, and tentative.

Prerequisites

Greenkeeper badge

  1. Sign up for an IBM Cloud account.
  2. Download the IBM Cloud CLI.
  3. Create an instance of the Tone Analyzer service and get your credentials:
    • Go to the Tone Analyzer page in the IBM Cloud Catalog.
    • Log in to your IBM Cloud account.
    • Click Create.
    • Click Show to view the service credentials.
    • Copy the apikey value, or copy the username and password values if your service instance doesn't provide an apikey.
    • Copy the url value.

Configuring the application

  1. In the application folder, copy the .env.example file and create a file called .env

    cp .env.example .env

  2. Open the .env file and add the service credentials that you obtained in the previous step.

    Example .env file that configures the apikey and url for a Tone Analyzer service instance hosted in the US East region:

    TONE_ANALYZER_IAM_APIKEY=X4rbi8vwZmKpXfowaS3GAsA7vdy17Qh7km5D6EzKLHL2
TONE_ANALYZER_URL=https://gateway-wdc.watsonplatform.net/tone-analyzer/api
    • If your service instance uses username and password credentials, add the TONE_ANALYZER_USERNAME and TONE_ANALYZER_PASSWORD variables to the .env file.

    Example .env file that configures the username, password, and url for a Tone Analyzer service instance hosted in the Sydney region:

    TONE_ANALYZER_USERNAME=522be-7b41-ab44-dec3-g1eab2ha73c6
TONE_ANALYZER_PASSWORD=A4Z5BdGENrwu8
TONE_ANALYZER_URL=https://gateway-syd.watsonplatform.net/tone-analyzer/api
