To run the AI Assistant in your improvement surroundings, full the next steps:

  1. Set the surroundings variables. Run the next command in your terminal. The AWS_REGION and WORKSPACE_ID ought to match the AWS area you employ and AWS IoT TwinMaker workspace you’ve gotten created.
    export AWS_REGION=us-east-1
    export WORKSPACE_ID=CookieFactoryV3

  2. Set up the required dependencies. Run the next instructions in your present terminal.
    cd <PROJECT_ROOT>/assistant
    ./set up.sh

  3. Launch the AI Assistant module. Run the next instructions in your present terminal.

    As soon as the module is began, it would launch your default browser and open the chat UI. You may shut the chat UI.

  4. Launch the Cookie Manufacturing unit dashboard app. Run the next instructions in your present terminal.
    cd <PROJECT_ROOT>/dashboard
    npm run dev
