@castleio/castle-js

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);

Usage

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);

Upgrade from 1.x script

Before

No longer available commands for _castle(...) :

`autoForwardClientId`, 'autoTrack', `catchHistoryErrors`, `identify`, `setUserId`, `setAccount`, `setKey`, `setAccount`, `sessionId`, `reset`, `page`, `trackPageView`, `setTrackerUrl`
