Eliom is a framework for building client/server Web and mobile applications in OCaml. It transforms OCaml into a multi-tier language, making it possible to implement both the server and client parts of a Web and mobile app as a single program. This simplifies a lot the communication between server and client. Applications can run on any Web browser or mobile device (iOS, Android), saving from the need to develop one version for each platform.

Eliom has support for reactive pages (generated on server or client), advanced session mechanism, server to client communication, continuation based Web programming, etc.

Eliom is part of the Ocsigen project.

We recommend that you use the OPAM package manager to install Eliom. Once you have installed OPAM, all you have to do is type:

opam install eliom

If you want to compile manually,

• run make to compile;
• run make PREFIX=${YOURPREFIX} install (as root if necessary) to install; and
• run make PREFIX=${YOURPREFIX} uninstall to uninstall everything.

• Install Eliom.

• Run make run.local or make run.opt.local in the Eliom source directory.

• Open http://localhost:8080/miniwiki in your browser.

• If the above does not work, look at the logs (see local/var/log/ in the Eliom source directory) or run Eliom with either of the options -v, -V (verbose and debug mode, respectively).

• Sources for this example may be found in the directory tests/miniwiki. A complete tutorial is available online. For a testsuite, see http://localhost:8080/.
