simple-csrf v1.0.1

simple-csrf

A dead simple CSRF middleware for Express (4.x): uses a single, per-session token with no unnecessary magic and/or tricks.

Install

$ npm install simple-csrf

Usage

Add after you have a session implementation:

var csrf = require('simple-csrf');
app.use(session_of_choice());
app.use(csrf());

Validation is performed on requests that are not of type GET, HEAD or OPTIONS. The token is retrieved from either _csrf_token in the request body parameters or the X-CSRF-Token request header.

The CSRF token is available as csrfToken on both the request object, and the renderer view locals.
