jquery-csrf-token

This package adds a csrf header to AJAX requests done via jQuery.

In the following situations no header is set:

• Cross Domain requests.
• Requests with type GET, HEAD, OPTIONS, or TRACE.

Laravel uses the X-CSRF-TOKEN header to check for a CSRF token. Django uses X-CSRFToken. This package defaults to X-CSRF-TOKEN for the header key, but you can change this using the config settings.

It's only dependency is on jQuery.

Installation:

$ npm install jquery-csrf-token --save

Usage

var csrfToken = require('jquery-csrf-token');

csrfToken.enable('my-beautiful-csrf-token', config);

csrfToken.setToken('updated-csrf-token');

Config

Name	Default	Description
key	X-CSRF-TOKEN	The key under which the csrf token should be send. Use X-CSRFTOKEN for Django.
retry	false	Allow to get a new token if the current one is expired

Retry

To be able to get a new token if the current one expired you need to pass a retry object for the config with two keys:

• url: URL to request the new token
• parseResponse: A function that takes the token request response as a parameter and return the new token
• isCSRFFailure (optional): A function that takes the failed request response as a parameter and return true if it's a CSRF failure. By default it just retry on every 403.

Example:

    csrfToken.enable(data.csrf_token, {
        key: 'X-CSRFTOKEN',
        retry: {
            url: 'api/bootstrap/',
            parseResponse: resp => resp.csrf_token,
            isCSRFFailure: resp => resp.statusCode === 403 && resp.responseJSON.message === 'CSRFFailure',
        },
    });
