  • A QbDVision API key

Getting Started

  1. Install the dependencies
npm install
  1. Copy .env.example to .env and fill in:
    1. Modify API_Key to be your QbDVision API key.
    2. Modify BASE_URL to point to your QbDVision environment if you're not using Sandbox.
    3. Modify PROJECT_ID and PROCESS_ID to be the project and process ID that you want to see.
  2. Build the example:
npm run build
  1. Download the process data:
npm run download
  1. Launch the web server:
npm run start
  1. Navigate to http://localhost:3000 in your browser.
