## pastebin.js
//
// There are many pastebin service: https://soso.ooo/search.html?q=pastebin
// This too, and with times limit, expiration, and browser User-Agent limit, allow only Go and Dart UA for Brook GUI
//
// This script will create a webserver on http://127.0.0.1:2023
// You can modify the listen address at the bottom of this file.
//
// Because the data is stored in localStorage, there is a size limit of 10M, and a clearing operation will be performed automatically after exceeding.
// So, you can fork and modify me.
//
// How to run:
// $ nami install deno
// $ deno run -A pastebin.js
//
// If you want daemon, you may prefer https://github.com/txthinking/joker
// If you want https, you may prefer https://github.com/txthinking/nico
