Funksie

A Feature Policy plugin for hapi.

Why the Name Funksie?

In Afrikaans the word Funksie means feature and it sounds similar to blankie a repo from which a lot of the code was taken

What is Feature Policy?

Feature policy is a HTTP response header that when set allows you to control which origins can use which features, both in the top-level page and in embedded frames.

Feature Policy provides a mechanism to explicitly declare what functionality is used (or not used), throughout your website. With Feature Policy, you opt-in to a set of "policies" for the browser to enforce on specific features used throughout a website. These policies restrict what APIs the site can access or modify the browser's default behavior for certain features.

Examples of what you can do with Feature Policy:

• Change the default behavior of autoplay on mobile and third party videos.
• Restrict a site from using sensitive APIs like magnetometer or microphone.
• Controls whether the current document is allowed to use the Payment Request API. If all your products and services are free, you can set this to none

Here's a link to the complete list.

Usage

This plugin depends on scooter to function.

To use it:

'use strict';

const Hapi = require('@hapi/hapi');
const Funksie = require('funksie');
const Scooter = require('@hapi/scooter');

const internals = {};

const server = Hapi.server();

internals.init = async () => {

    await server.register([Scooter, {
        plugin: Funksie,
        options: {} // specify options here
    }]);

    await server.start();
};

internals.init().catch((err) => {

    throw err;
});

Options may also be set on a per-route basis:

'use strict';

const Hapi = require('@hapi/hapi');
const Funksie = require('funksie');
const Scooter = require('@hapi/scooter');

const server = Hapi.server();

server.route({
    method: 'GET',
    path: '/capture',
    config: {
        handler: (request, h) => {

            return 'capturing this';
        },
        plugins: {
            funksie: {
                cameraSrc: 'self'
            }
        }
    }
});

Note that this setting will NOT be merged with your server-wide settings.

You may also set config.plugins.funksie equal to false on a route to disable Feature-Policy headers completely for that route.
