Castle Fingerprinting Script

Packaged version of Castle fingerprinting script.

Introduction

The Castle JavaScript automatically captures every user action in your web application, including clicks, taps, swipes, form submissions, and page views. We use this data to build profiles of good user behavior in order to detect the bad.

Installation

npm install --save @castleio/castle-js

yarn add @castleio/castle-js

Configuration

Basic configuration of the app

// @option options [string] :pk castle publishable key.
// @option options [object] :window (default `window`) eg JSDOM.window
// @option options [boolean] :avoidCookies (default `false`) when true cookies usage will be avoided
// @option options [string] :cookieDomain (default topLevel domain) cookies domain scope
// @option options [string] :apiUrl (default `https://m.castle.io/v1/monitor`) castle api url
// @option options [number] :timeout (default 1000) castle api response timeout
// @option options [boolean] :verbose (default true) verbose mode

import * as Castle from '@castleio/castle-js'

Castle.configure(options);

browser version (legacy setups)

If your environment does not support modules you can use the browser version

import '@castleio/castle-js/dist/castle.browser.js'

Castle.configure(options);

Usage

Getting castle request token

import * as Castle from '@castleio/castle-js'

Castle.createRequestToken().then( (requestToken) => {

const requestToken = await Castle.createRequestToken();

See Castle Docs for more information and how to pass the token further.

form submit helper example (when cdn version is used)

// @param event [Event] submit event
// @param onDone [Function] optional form submit callback replacement
<form action="/" onsubmit="Castle.injectTokenOnSubmit(event)">
  <button type="submit">Submit</button>
</form>

helper is also available directly (when castle.umd.js is used)

import * as Castle from '@castleio/castle-js'

const submitHandler = (evt) => Castle.injectTokenOnSubmit(evt);
<form action="/" onsubmit="submitHandler(event)">
  <button type="submit">Submit</button>

// @option name [String]
// @option referrer [String]
// @option url [String]

import * as Castle from '@castleio/castle-js'

const page = Castle.page(options);
