tinyfiledialogs-deno
This is a port of tinyfiledialogs-rs for use in Deno. It requires --unstable --allow-plugin --allow-net --allow-read --allow-write (because it uses a native plugin).
Example
import * as tinyfiledialogs from "https://deno.land/x/tinyfiledialogs@1.0.1/mod.ts"
tinyfiledialogs.messageBoxOk("Title", "Content", tinyfiledialogs.MessageBoxIcon.Info)
