Back up and restore an IndexedDB database

This gist is an ES module which provides functions to import and export data from an IndexedDB database as JSON. It's based on Justin Emery's indexeddb-export-import package, but applies some adjustments that reflect better on the current browser landscape (i.e. better developer ergonomics but no support for Internet Explorer).

Usage

For each of the provided functionalities, you need a connected IDBDatabase instance.

Export Data

import { idb } from 'some-database'

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, exa, fd, hyperfine, miniserve, ripgrep, just, zoxide and cargo-wipe.

bandwhich: Terminal bandwidth utilization tool
bat: A replacement for cat that provides syntax highlighting and other features.
bottom: Yet another cross-platform graphical process/system monitor.

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

 int x;

Intro

TCL-Expect scripts are an amazingly easy way to script out laborious tasks in the shell when you need to be interactive with the console. Think of them as a "macro" or way to programmaticly step through a process you would run by hand. They are similar to shell scripts but utilize the .tcl extension and a different #! call.

Setup Your Script

The first step, similar to writing a bash script, is to tell the script what it's executing under. For expect we use the following:

#!/usr/bin/expect

	name: Basic API call (TypeScript)
	description: Performs a basic Word API call using TypeScript.
	host: WORD
	api_set: {}
	script:
	content: \|
	$("#run").click(() => tryCatch(run));

	async function run() {
	// Gets the current selection and changes the font color to red.

	async function run() {
