Express Helpers

Express Helpers is a port of EJS's ViewHelpers and additional helpers are very similar to those found in the Ruby on Rails framework.

Installation

npm install express-helpers

How to use

Require express and create a server.

var express = require('express');
var app = express.createServer();

To automatically inclue all helpers initialize like this.

var helpers = require('express-helpers')(app);

Or more simply if you don't need any reference to the helpers object

require('express-helpers')(app);

If you want to only use some helpers require without the app and register necessary view helpers...

Express 3.0

var helpers = require('express-helpers')();

app.locals.date_tag = helpers.date_tag;

Note: The is_current_page and link_to_unless_current helpers are not available like this since they need to be setup as middleware

Express 2.0

var helpers = require('express-helpers')();

app.helpers({
   date_tag: helpers.date_tag
});

Then use it in a ejs view like a rails view

<% form_for("user", function(f){ %>
    <%- f.label_for("username") %>
    <%- f.text_field("username") %><br />

    <%- f.submit() %><br />
<% }) %>
