sails-hook-flash

The simplest way to use flash messages in your Sails application. This is useful when you want to redirect and have a special message shown on the next page.

Example

Add a new flash message

// api/controllers/UserController.js
login: function (req, res) {
  req.addFlash('success', 'A success message');
  return res.redirect('/sample/success');
}

Render your flash message

// views/admin/index.ejs
<% flash.get('success').forEach(function (message) { %>
    <div class="alert alert-success">
       <%= message %>
       <button type="button" class="close" data-dismiss="alert" aria-label="Close">
           <span aria-hidden="true">&times;</span>
       </button>
    </div>
<% }) %>

NOTE: The EJS view engine is used in this sample, but you're not limited to it.
