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'

Debugging vitess with delve

In this guide, we will run vitess in a docker container, and hook into it with delve, a go debugger. This will allow us to debug via a command line interface to delve, or even via a go IDE such as Jetbrains's GoLand.

Table of contents

• Get the source code
• Build the new docker image
• Run the docker image
  • Increase Docker Engine resources
  • Create an init script to initialize all vitess components in the container
• Run the container

There is a nice GIF illustrating a technique called "frustum culling" in this Kotaku article: http://kotaku.com/horizon-zero-dawn-uses-all-sorts-of-clever-tricks-to-lo-1794385026

The interwebs being what they are, this has also led to some controversy.

Some people have interpreted the opening sentence "Every time you move the camera in Horizon Zero Dawn, the game is doing all sorts of under-the-hood calculations, loading and unloading chunks of world to ensure that it all runs properly," as being about the GIF; that's not what frustum culling does, but that's probably not what the article's author meant anyway.
