Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
Given an group of paths (say, from an API schema), you might need to create a set of proxy objects for interacting with those paths. This is the situation I found myself in while working on the Node client for the Heroku API.
Given a set of paths and a base constructor function, path-proxy will create a network of logical proxy objects based on the paths and attach it to the constructor's prototype.
npm install path-proxy --save
var pathProxy = require('path-proxy');
function ApiClient() {}
pathProxy.proxy(ApiClient, [
"/foo",
"/foo/{id}/bar"
]);
var client = new ApiClient();
client.foo("qux").bar();
This may not appear all that useful—they're mostly just empty functions—until you start mucking around with their prototypes:
var BarProxy = pathProxy.pathProxy(ApiClient, "/foo/{id}/bar");
BarProxy.prototype.sayHello = function () {
console.log("hello");
};
client.foo("qux").bar().sayHello(); // Logs "hello".
They also have access to a few useful attributes:
var baz = client.foo("qux").bar("baz");
baz.params; // ["qux", "baz"]
baz.pathSegments; // ["foo", "qux", "bar", "baz"]
baz.path; // "/foo/qux/bar/baz"
And can access the instance of the base constructor they're based off of:
ApiClient.prototype.delete = function (path, callback) {
var message = this.name + " deleted at " + path;
callback(message);
};
var client = new ApiClient();
client.name = "Jonathan";
BarProxy.prototype.delete = function (callback) {
this.base.delete(this.path, callback);
};
// This:
client.foo("qux").bar("baz").delete(function (message) {
// message == "Jonathan deleted at /foo/qux/bar/baz"
});
// Is equivalent to this:
client.delete("/foo/qux/bar/baz", function (message) {
// message == "Jonathan deleted at /foo/qux/bar/baz"
});
That's all there is for now. This is might prove to be a useful tool for working on documented API clients in the future. For now, don't rely on it. There are no tests, and it's more of a fun experiment at the moment
