jquery-csrf-prefilter v1.1.0

jquery-csrf-prefilter

jQuery prefilter for automatically inserting a CSRF token with every destructive AJAX request.

Installation

Install using npm:

$ npm install jquery-csrf-prefilter

Usage

jquery-csrf-prefilter is a factory function that, given a CSRF token string (or a function that returns the CSRF token string), will return a function that can be passed to $.ajaxPrefilter to inject the token into subsequent AJAX requests. By default, this prefilter will add the token via a X-CSRF-Token header with all requests that are not of the types GET, OPTIONS, HEAD, or TRACE. This functionality can be further customized with a second options param.

Basic example which adds a X-CSRF-Token header with each POST, PUT, PATCH, and DELETE request:

var $ = require('jquery'),
    createCsrfPrefilter = require('jquery-csrf-token'),
    tokenValue = $('meta[name="csrf-token"]').attr('content');

$.ajaxPrefilter(createCsrfPrefilter(tokenValue));

Available Options

The following options may be specified when creating a CSRF prefilter:

header (string)

Specify the header that is to be used. Replaces the default X-CSRF-Token header. This option may be specified in addition to data and/or query; all will be added to the request.

Example:

$.ajaxPrefilter(createCsrfPrefilter(tokenValue, { header: 'X-CSRFToken' }));`

data (string)

Key that is to be added to the form/JSON data payload of the request. Replaces the default X-CSRF-Token header. This option may be specified in addition to header and/or query; all will be added to the request.

Example:

$.ajaxPrefilter(createCsrfPrefilter(tokenValue, { data: '_csrf' }));`

query (string)

Key that is to be added as a query param to the request. Replaces the default X-CSRF-Token header. This option may be specified in addition to header and/or data; all will be added to the request.

Example:

$.ajaxPrefilter(createCsrfPrefilter(tokenValue, { query: '_csrf' }));`

ignoreMethods (array)

Request methods to be ignored for the purposes of injecting the CSRF token. By default, this value is ['GET', 'OPTIONS', 'HEAD', 'TRACE'].
