Direct recursion over file system from the frontend — Electric Clojure (2022 June)

This video demonstrates traversing a filesystem tree from the frontend. The filesystem tree exists only on the server, and the HTML view exists only on the client. Nonetheless, we are able to unify the query/view logic into a single recursion in the simple, direct style of PHP, despite network. The Electric compiler automatically coordinates fine-grained reactive network sync.

Code note: in this video from last year, ~@ is the legacy syntax for client/server transfer, it has since been superseded by e/client and e/server markers.

  • No API, no client side database, no frontend state at all (except DOM)
  • Literally all accidental complexity GONE
  • Look how fast it is! It's incremental/streaming network, not request/response.
  • Electric brings a higher level of expressiveness and fluency than was possible before
