#  - Ignores lodash dependency
#  - Disables version-updates

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "daily"
    ignore:
      - dependency-name: "lodash"
        # For Lodash, ignore all updates
    # Disable version updates for npm dependencies
    open-pull-requests-limit: 0
