Content Security Policy builder

Take an object and turn it into a Content Security Policy string.

It can handle a lot of things you can you throw at it; camelCased or dash-separated directives, arrays or strings, et cetera.

Usage:

import builder from "content-security-policy-builder";

// default-src 'self' default.com; script-src scripts.com; whatever-src something; object-src
builder({
  directives: {
    defaultSrc: ["'self'", "default.com"],
    scriptSrc: "scripts.com",
    "whatever-src": "something",
    objectSrc: true,
  },
});

// default-src 'self'; whatever-src something
builder({
  directives: new Map([
    ["defaultSrc", ["'self'", "default.com"]],
    ["whatever-src", "something"],
  ]),
});

This module is considered complete. I expect to continue maintenance if needed, but I don't plan to add features or make breaking changes.
