The wget command you'll need to use is much lengthier as explained below. As such, you may wish to commit it to a file like wholesite.sh, make it an executable, and run it. It'll create a directory of the url and subdirectories of the site's assets, including images, js, css, etc.

wget \
     --recursive \
     --level 5 \
     --no-clobber \
 --page-requisites \

// Modify an object, passing an explicit key array. The callback only has access to the keys in the array.
function modify<T, K extends keyof T>(instance: T, keys: K[], update: (v: Pick<T, K>) => void) {
  const draft = structuredClone(instance);
  update(draft);
  // for example's sake, just log the changed keys
  for (let k of keys) {
    console.log("updated", k, "from", instance[k], "to", draft[k]);
  }

Frame RPC helper

This set of helpers makes it easy to communicate with an iframe via JSON RPC.

This gist contains both the TypeScript source code, and a stripped JavaScript version.

If you have an iframe on your page you want to communicate with, download the source code and use it like so:

import {makeRpcClient, makeRpcServer} from "./framerpc.js";

Run this code using Deno:

deno run https://gist.githubusercontent.com/crabmusket/2c8c6e692974edd56cd6ab8fee14addd/raw/869958a7094daf17b36be6ac078aa0eafb4b0a9d/benchmark.js

It will prompt you for two network permissions, to download the sample data files.

Use this snippet to parse, modify and render environment files.

Deno micro modules

Each of these modules is a single file consisting of no more than a page or two of code, which provide some useful 'generic' feature. These modules could be copied as-is into any TypeScript project, but they're designed to work with Deno. Deno's URL loading makes it very easy to import them.

• semaphore.ts, an async Semaphore class
• json.ts, a JsonValue type and utility functions
• title_case.ts, convert strings to 'Title Case'

semaphore.ts

An asynchronous semaphore utility class meant to work with Deno. You can use it to implement rate-limiting and other concurrency patterns.

Usage example:

import { Semaphore } from "https://gist.githubusercontent.com/crabmusket/681b4f81ed05716f8dd10ac88d1d960b/raw/5e7c18013e896425d1048324f8668932f23437df/semaphore.ts";

/** For the spec of the JSON type, see http://json.org */
export type JsonValue = JsonObject | JsonArray | number | string | boolean | null;

/** JSON objects can have any string key. */
export interface JsonObject {[key: string]: JsonValue};

/** For the explanation of this type, see https://github.com/Microsoft/TypeScript/issues/3496#issuecomment-128553540 */
export interface JsonArray extends Array<JsonValue> {};

/** Narrow the type of a JsonValue to check if it's an object. */
