Very similar to the unmaintained project express-uncapitalize, this middleware redirects any requests which contain uppercase chars to their lowercase forms. With two main changes from the original:

1. Works with all utf-8 strings in paths
2. Keeps query parameters intact

Installation

npm install express-lowercase-paths

Usage

var lowercasePaths = require("express-lowercase-paths")
app.use(lowercasePaths())

Options

Redirecting with specific status code

To redirect with a specific status code, pass the redirectStatusCode option to the middleware:

var lowercasePaths = require("express-lowercase-paths")
app.use(lowercasePaths({redirectStatusCode: 301}))
