Welcome to WebPerl!

WebPerl uses the power of WebAssembly and Emscripten to let you run Perl in the browser!

WebPerl does not translate your Perl code to JavaScript, instead, it is a port of the perl binary to WebAssembly, so that you have the full power of Perl at your disposal!

Notice: WebPerl is very much in beta. Some things may not work yet, and parts of the API may still change. Your feedback is always appreciated!

New: Experimental Perl 6 Support

<script src="webperl.js"></script>
<script type="text/perl">

print "Hello, Perl World!\n";  # goes to JavaScript console by default

js('document')->getElementById('my_button')
	->addEventListener('click', sub {
		js('window')->alert("You clicked the button!");
	} );
</script>

For web applications written with WebPerl, see:

Quick Start

Prerequisites: perl (a recent version is recommended, e.g. v5.26 and up), and cpanm to easily install dependencies (otherwise, see the file cpanfile for the dependencies and use the module installer of your choce).

In a shell:

$ wget https://github.com/haukex/webperl/releases/download/v0.09-beta/webperl_prebuilt_v0.09-beta.zip
$ unzip webperl_prebuilt_v0.09-beta.zip
$ cd webperl_prebuilt_v0.09-beta
$ cpanm --installdeps .
$ plackup webperl.psgi
HTTP::Server::PSGI: Accepting connections at http://0:5000/

Then point your browser at http://localhost:5000/webperl_demo.html and have a look at its source. The ZIP archive also contains several other examples, which you can access at http://localhost:5000/.

You may also host the contents of the above ZIP archive on a webserver of your choice, or some browsers will support opening the files locally; both are described in Serving WebPerl. (Note: In webperl_demo.html, you’ll likely see “AJAX Failed!”, which is to be expected since your webserver won’t know how to handle the example AJAX request.)

Have fun!

Please see the “Legal” page for details.
