Hanami::UJS

Unobtrusive JavaScript (UJS) for Hanami.

Status

Installation

Add this line to your Hanami project's Gemfile:

gem "hanami-ujs"

And then execute:

$ bundle

Or install it yourself as:

$ gem install hanami-ujs

Usage

Setup

You have to add two lines to the application layout (eg. apps/web/templates/application.html.erb):

<%= csrf_meta_tags %> inside <head>
<%= javascript "hanami-ujs" %> the location is optional, but before </body> is a good spot.

Events

Hanami UJS fires events to notify listeners that a certain operation happened:

"ajax.before"
"ajax.complete"

You can listen to these events with:

(function() {
  var ajaxBeforeHandler = function(event) {
    console.log(event);
  };

  var ajaxCompleteHandler = function(event) {
    console.log(event);
  };

  document.addEventListener("ajax:before", ajaxBeforeHandler);
  document.addEventListener("ajax:complete", ajaxCompleteHandler);
})();

AJAX Form

<%=
  form_for :search, "/search", remote: true do
    # ...

    submit "Search"
  end
%>

When the user will hit "Search" the form will be sent via AJAX.

Development

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
