Features

• The <Spawn />
  • starts executing a child process as it mounts,
  • kills the process as it unmounts and prints,
  • renders a configurable status text (running, succeeded, failed),
  • renders the last lines below the status of a running process.
  • propagates terminal interrupts (users pressing Ctrl + C)
• The <Script />
  • Wraps <Spawn /> and any other elements element.
  • Sequential mode (default): Renders only the subset of completed children and the currently running runnable (<Spawn /> and other nested <Script />).
  • Parallel mode: Renders all children, making processes spawn in parallel.
  • Infinitely composable: Put parallel scripts, inside sequential scripts, inside ...
