Fastify plugin to opt-out of Google's FLoC advertising-surveillance network

Intro

The fastify-floc-off plugin sets the following response header and values to opt-out of Google's FLoC advertising-surveillance network:

Permissions-Policy: interest-cohort=()

You can read more about the issues surrounding Google's FLoC on EFF and Plausible Analytics.

Helmet (and in turn fastify-helmet) does not currently support Permissions-Policy response header setting yet, so this plugin was created out of a need for an easy way to disable/opt-out of Google's FLoC network for systems at Yeovil District Hospital NHS Foundation Trust. This ensures both patients and staff accessing web applications at the hospital are not subject to Google's unsolicited tracking.

Installation

Install using npm:

npm install fastify-floc-off

Or yarn:

yarn add fastify-floc-off

fastify-floc-off's test scripts use npm commands.

Example Usage

const Fastify = require("fastify");
const flocOff = require("fastify-floc-off");

const server = Fastify();
server.register(flocOff);

server.get("/", (req, res) => {
    res.send("ok");
});

server.listen(3000);
