Express-NormalizeUrl

URL normalisation for Express and Connect. Forked from deleted @AntuanKhanna/express-url to serve as an (almost) drop-in replacement (please see Middleware options for that matter) for an unmaintained project.

About

Taking care of

• trailing slashes
• repeated slashes
• repeated question marks
• repeated ampersands
• repeated query strings
• case sensitivity (does not affect queries by default)

Redirect example

//assuming default options (see Middleware options)
request:  //sLuG??param=val&&param2=VAL2
response: /slug/?param=val&param2=VAL2

Installation

$ npm install express-normalizeurl

Usage

As middleware

// Require module
// If you used express-url before, this is the only line you need to change
var expurl = require('express-normalizeurl');

// Process routes through middleware
app.use(expurl());

Middleware options

app.use(expurl({
    requestType: 'GET',
    redirectStatusCode: 302, 
    lowercase: true,
    lowercaseQueries: false, // False by default, requires lowercase to be set to true to work. If you want 100% compatibility with express-url, when lowercase is true, this also needs to be set true
    trailingSlash: true,
    repeatedSlash: true,
    repeatedQuestionMark: true,
    repeatedAmpersand: true
}));

Tests

$ npm install
$ cd node_modules/express-normalizeurl
$ npm test

Recommendations

• do not serve static files with node directly
• use case sensitive and strict routing

app.set('case sensitive routing', true);
app.set('strict routing', true);
