Discord HTML Transcripts is a node.js module (recode on JDA) (again recoded on Javacord) to generate nice looking HTML transcripts. Processes discord markdown like bold, italics, strikethroughs, and more. Nicely formats attachments and embeds. Built in XSS protection, preventing users from inserting html tags.
This module is designed to work with Javacord.
HTML Template stolen from DiscordChatExporter.

transcript.createTranscript(textChannel);

transcript.generateFromMessages(messages); // return to InputStream
