express-toastr

wercker status

A toastr.js middleware for ExpressJS 4

Installation

npm install express-toastr

Requirements

express-toastr depends on connect-flash, express-session, and cookie-parser -- see the Usage section below.

Usage

Require express-toastr as a middleware:

// ExpressJS
var express = require('express')
// Dependencies
    ,flash = require('connect-flash')
    ,session = require('express-session')
    ,cookieParser = require('cookie-parser')
// express-toastr
    ,toastr = require('express-toastr');
 
// Initialize ExpressJS
var app = express();
// Dependencies
app.use(cookieParser('secret'));
app.use(session({
    secret: 'secret',
    saveUninitialized: true,
    resave: true
});
app.use(flash());
 
// Load express-toastr
// You can pass an object of default options to toastr(), see example/index.coffee
app.use(toastr());

In your controller:

if (err)
{
    req.toastr.error('Invalid credentials.');
} else {
    req.toastr.success('Successfully logged in.', "You're in!");
}
 
//...
 
res.render('viewName', {req: req});

In your view:

<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.2/css/toastr.min.css">
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.2/js/toastr.min.js"></script>
<%= req.toastr.render() %>

Alternatively, you can add a middleware as follows:

app.use(function (req, res, next)
{
    res.locals.toasts = req.toastr.render()
    next()
});

and in your view:

<!-- toastr.min.css, jquery.min.js, toastr.min.js -->
<%= toasts %>

Also see example/index.coffee.

Available methods

// Add an info toast
req.toastr.info(message, title = '', options = {})
// Add a warning toast
req.toastr.warning(message, title = '', options = {})
// Add an error toast
req.toastr.error(message, title = '', options = {})
// Add a success toast
req.toastr.success(message, title = '', options = {})
// Add a toast with a manually specified type
req.toastr.add(type, message, title = '', options = {})
// Clear existing toasts
req.toastr.clear()
