Additional information

Question: How do you find the root build directory to use in the artifact build setting. I created my own build folder instead.

Hi @mcdeagles 👋 , thanks for reaching out. The default build directory for your app will vary based on your app framework. For example, if you are building a react app via CRA it will generate a build directory for your artifacts when you do a production build via npm run build. If you want to use a custom folder instead of build for the output, you can achieve this via either of the methods:

• Modify the build script in the package.json file: https://create-react-app.dev/docs/advanced-configuration
• Move the build folder post the build process:

build:
  commands:
     - npm run build
     - mkdir -p custom_folder
     - mv build custom_folder
  artifacts:
    baseDirectory: custom_folder
