fastify-floc-off

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

Overview

The fastify-floc-off plugin adds the "interest-cohort=()" directive to the Permissions-Policy response header to opt-out of Google's FLoC advertising-surveillance network. It will create a new header if one does not already exist.

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

Helmet and fastify-helmet do not support the 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. This ensures users accessing web applications are not subject to Google's unsolicited tracking.

Installation

Install using npm:

npm i fastify-floc-off

For Fastify v3.x support, use fastify-floc-off@1.0.7.

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");
});

await server.listen({ port: 3000 });
