Ocsigen Start is a set of higher-level libraries for building client-server web applications with Ocsigen (Js_of_ocaml and Eliom). It provides modules for

  • user management (session management, registration, action — e.g., activation — keys, ...),
  • managing groups of users,
  • displaying tips, and
  • easily sending notifications to the users.

Ocsigen Start comes with an eliom-distillery template for an app with a database, user management, and session management. This template is intended to serve as a basis for quickly building the Minimum Viable Product for web applications with users.

opam install ocsigen-start
