This is a very simple plugin for Express that does very little beyond make CSRF a touch easier to use. It does two things: enable CSRF protection using the built-in CSRF middleware, and exposes a "csrf" dynamic variable which can be rendered directly inside views for reuse by forms and JS.
Not much really, but I found myself pasting this code over and over again, hence the module.
// somewhere after session and body parsing have been set up, but before any of your // handlers kick in require("express-csrf-plug").plugCSRF(app);
$ npm install express-csrf-plug
This module exports a single method: plugCSRF(). It takes your app object and sets it up as described on the tin.
