    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()

    Allowed initialization parameters

    BorosTcf.init({language, reporter})

    • language (optional, defaults to 'es'), a valid two-letter ISO 639-1 language code
    • reporter (optional), a function which can receive (event, payload) parameters. Boros TCF relevant actions will be notified to the reporter, which can be used p.ex. to debug.

    Boros TCF actually will report events

    • LISTENER_ERROR: any error on registered event status listeners
    • USE_CASE_CALLED: any call to the use cases, which has finished OK
    • USE_CASE_ERROR: any call to the use cases, which has failed due to an error
    • LOAD_CONSENT_ERROR: loading the stored consent catched an error and an empty consent will be returned
