iab-tcf

Go code to parse IAB v1/v2 consent based on github.com/LiveRamp/iabconsent library.

This package is just a wrapper on their amazing work to fill our needs.

Usage

Install

go get github.com/hybridtheory/iab-tcf

Example

package main

import (
    "fmt"
    iab "github.com/hybridtheory/iab-tcf"
)

func main() {
    encoded := "COyt4MbOyt4MbMOAAAENAiCgAIAAAAAAAAAAADEAAgIAAAAAAAA.YAAAAAAAAAA"
    consent, err := iab.NewConsent(encoded)
}

CMP vendor list

In order to validate if the CMP received belongs to a valid id there's a loader integrated with the library.

package main

import (
    "fmt"
    iab "github.com/hybridtheory/iab-tcf"
    cmp "github.com/hybridtheory/iab-tcf/cmp"
)

func main() {
    cmp.NewLoader().LoadIDs()
    consent, err := iab.NewConsent(encoded)
    consent.IsCMPValid() // This will return true/false depending on the ids loaded.
}

If instead of the default vendor list https://cmplist.consensu.org/v2/cmp-list.json we want to use our own, we can use an option:

err := cmp.NewLoader(cmp.WithURL("https://example.com/cmp-list.json")).LoadIDs()

The format of the JSON must be the same.

If we want to use our own list of valid CMPs we can simply set the variable:

cmp.ValidCMPs = []int{1, 123}

Testing

We use Ginkgo and Gomega for testing purposes.
