# micro-csrf

[![Build Status](https://travis-ci.org/fourcube/micro-csrf.svg?branch=master)](https://travis-ci.org/fourcube/micro-csrf)

`micro-csrf` is a csrf middleware for Zeit.co's [micro](https://github.com/zeit/micro) framework. This module is heavily inspired by [`express-csurf`](https://github.com/expressjs/csurf).

## Installation

```bash

$ npm install micro-csrf

# or

$ yarn add micro-csrf

```

## Example Usage

```javascript

// Use the micro-session middleware for storing the token secret

const SessionManager, { MemoryStore } = require('micro-session');

const { csrfMiddleware } = require('micro-csrf');

const sessionManager = SessionManager({

  store: new MemoryStore(),

  secret: 'my session secret'

})

const csrf = csrfMiddleware();

module.exports = async (req, res) => {

  let session = await getSession(req, res);

  // This will automatically end the request with a 403 error

  // if this is a POST, PUT, PATCH, DELETE request without a valid

  // CSRF Token.

  const csrfToken = await csrf(session, req, res);

  // ...

  return {

    csrfToken

  };

};

```

## Token Validation

The token is automatically read from the following locations:

```

    req.body._csrf - requires a parsed request body

    req.query._csrf - requires a query parser

    req.headers['csrf-token'] - the CSRF-Token HTTP request header.

    req.headers['xsrf-token'] - the XSRF-Token HTTP request header.

    req.headers['x-csrf-token'] - the X-CSRF-Token HTTP request header.

    req.headers['x-xsrf-token'] - the X-XSRF-Token HTTP request header.

```
