    Greentrace lib

    The standalone library used by the GreenTrace App to show

    • where packets are hoping through the world when you make a request from your machine, based on the Geolite IP Database

    • which hops pass through infrastructure running on green energy, as listed by the Green Web Foundation


    As a command line tool

    This will run a traceroute, then print to STDOUT a GeoJSON file with coordinates for every IP address, as looked up in the GeoIP database.

    npx greentrace

    Note: it's not fast. I'd welcome pointers on making this run faster, without losing too much info.

    As a library

    You can also run this as a library in a larger application. You can see this in use in the greentrace electron app, designed plot these hops on a map.

    import GreenTrace from "@tgwf/greentrace-lib"
    // return a Promise, that resolves to an array
    const hops = await GreenTrace.trace(domainName)
    // make this into something we can put on a map
    const hopsAsgeoJSON = hops.toGeoJSON()


    There are two licenses, for the code and data. See the LICENSE file for details.


    npm i @tgwf/greentrace-cli
