Prerequisites

    Both Hydra-CLI and the generated project files have dependencies that require Node v10.16 or higher
    npm and (optional, but recommended) npx​
    Hydra stores the substrate data in an external PostgresSQL 12 instance. The scaffolding tool provides a convenient shortcut for running the database instance from a Docker image. In this case the standard docker environment (docker and docker-compose) should be available.
    (Optional) Docker engine. The scaffolding tool provides targets for building Docker images for external deployment.
