@ibm-watson/discovery-nodejs v1.0.2

Demo: https://discovery-news-demo.ng.bluemix.net/

Prerequisites

1. Sign up for an IBM Cloud account.
2. Download the IBM Cloud CLI.
3. Create an instance of the Discovery service and get your credentials:
   • Go to the Discovery 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 Discovery service instance hosted in the US East region:

   DISCOVERY_IAM_APIKEY=X4rbi8vwZmKpXfowaS3GAsA7vdy17Qh7km5D6EzKLHL2
   DISCOVERY_URL=https://gateway-wdc.watsonplatform.net/discovery/api

   • If your service instance uses username and password credentials, add the DISCOVERY_USERNAME and DISCOVERY_PASSWORD variables to the .env file.

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

   DISCOVERY_USERNAME=522be-7b41-ab44-dec3-g1eab2ha73c6
   DISCOVERY_PASSWORD=A4Z5BdGENrwu8
   DISCOVERY_URL=https://gateway-syd.watsonplatform.net/discovery/api
