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

``bash
npm install --save @castleio/castle-js

`

`bash
yarn add @castleio/castle-js

`

Configuration




$3

`js
// @option options [string] :pk castle publishable key.
// @option options [object] :window (default window) eg JSDOM.window
// @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 (console warnings)
// @option options [object] :storage (default name __cuid, default expireIn 400 days in seconds: 34560000) used for storing uuid in the localStorage and the cookies, and for setting cookie expiration time.

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

Breaking changes

Upgrading from 1.x to 2.0.x

$3

Legacy package: https://www.npmjs.com/package/castle.js

`js
require "castle.js"
`

`js
_castle('setAppId', "YOUR_APP_ID")
_castle('getClientId')
`

$3

New package:

`js
import * as Castle from "@castleio/castle-js"
`

1. Renamed the main object from _castle to Castle in the new module, but kept the _castle in the CDN version as well as the browser-specific module @castleio/castle-js/dist/castle.browser.js
2. Introduced the concept of request tokens that need to be generated for each call to Castle's server-side API.

`js
Castle.createRequestToken().then( (requestToken) => {
});

// or

const token = await Castle.createRequestToken();
`

3. Request tokens can no longer be retrieved from the cookie string.
4. All the following methods were removed:

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


Request Token is now required to be passed in the request params and it is no longer available in the cookie. Check the docs

Upgrading from 2.0.x to 2.1.x or later

$3

`js
Castle.configure(YOUR_CASTLE_APP_ID);
`

$3

1. Removed the _castle object for all versions and now only relying on Castle.

2. Switched to use the Publishable Key that can be found in the same place as the now deprecated App ID.

`js
Castle.configure({pk: YOUR_PUBLISHABLE_KEY});
`

3. onFormSubmit has been renamed to injectTokenOnSubmit

4. _castle global method is no longer supported and has been replaced with Castle (for the CDN and castle.browser.js versions) check docs

5. CDN version no longer needs appID in the url and requires
`javascript

`
to be added. The CDN version can't be used for generating request tokens, but only for tracking client-side events.

6. Introduced page, form, and custom methods for client-side event tracking
