@flashfix/express-sanitizeurl

ExpressJS middleware that checks request URL for potentially breaking things, such as:

• Unparsable query string sequences that would crash on attempt to parse on the client side
• Double question mark in URL
• Multiple slashes

After one of the above checks fails the middleware attempts to guess a safe variant of the url and redirect there.

Options:

• redirectTo (string): When url contains breaking character sequences and is impossible to parse, redirect to this URL, default: '/'

Usage:

app.use(require('@flashfix/express-sanitizeurl')());
