A little app based on a set of prompts published by Sean McCoy.
It displays this week's prompt, stores your previous entries, and hooks up to several APIs to generate random NPC names, loot and monsters for your dungeon. You can change the theme colour and use the Scroll to copy all your entries for the week to your clipboard.
This is a simple app built in React with vanilla CSS. It stores entries in localstorage (handled by a custom hook) using localforage. My favourite file is RandomGenerator.js because I find config objects really satisfying (L86).
