Table of Contents


Boros TCF is a stand alone Consent Management Provider solution compliant with the "Transparency & Consent Framework version 2.0" standard established by the IAB Europe.


  • Initialization with Stub, see details here

  • Extra cookie storage

    A cookie named "borosTcf" is stored with the user consents stringified data, encoded in Base64.

    Sample borosTcf value: eyJwb2xpY3lWZXJzaW9uIjoyLCJjbXBWZXJzaW9uIjoxLCJwdXJwb3NlIjp7ImNvbnNlbnRzIjp7IjEiOnRydWUsIjIiOnRydWUsIjMiOnRydWUsIjQiOnRydWUsIjUiOnRydWUsIjYiOnRydWUsIjciOnRydWUsIjgiOnRydWUsIjkiOnRydWUsIjEwIjp0cnVlfX0sInNwZWNpYWxGZWF0dXJlcyI6eyIxIjp0cnVlfX0=

    The encoded data in this sample value, and the cookie encoded data structure is:

      "policyVersion": 2,
      "cmpVersion": 1,
      "purpose": {
        "consents": {
          "1": true,
          "2": true,
          "3": true,
          "4": true,
          "5": true,
          "6": true,
          "7": true,
          "8": true,
          "9": true,
          "10": true
      "specialFeatures": {
        "1": true

    To decode the cookie, p.ex.:

    // Java
    String decoded = new String(Base64.getDecoder().decode(cookieValue));
    // Node
    const decoded = Buffer.from(cookieValue, 'base64').toString()

npm i @adv-ui/boros-tcf


import BorosTcf from '@adv-ui/boros-tcf'

const borosTcf = BorosTcf.init()
