Express Messages

The express-messages module provides flash notification rendering.

Express 2.x

To use simply assign it to a dynamic helper:

app.dynamicHelpers({ messages: require('express-messages') });

Express 3+

Install connect-flash and add them as middleware:

app.use(require('connect-flash')());
app.use(function (req, res, next) {
  res.locals.messages = require('express-messages')(req, res);
  next();
});

Installation

$ npm install express-messages

Usage

On the server, add messages like this:

req.flash("info", "herp derp %s", something)

Then in a view you may output the notifications based on your templating engine:

EJS

<%- messages() %>

Jade

!= messages()

Which outputs HTML as shown below:

<div id="messages">
  <ul class="info">
    <li>Email queued</li>
    <li>Email sent</li>
  </ul>
  <ul class="error">
    <li>Email delivery failed</li>
  </ul>
</div>

Running Tests

First make sure you have the submodules:

$ git submodule update --init

Then run the tests:

$ make test
