Line breaks in messages are ignored

[drygdryg]

Rocket.Chat uses newlines to separate lines in messages. Showdown by default expects Markdown-style line breaks (two spaces and a newline).
We should pass simpleLineBreaks=true (doc) to the Showdown options to convert the newline character to <br>.

const converterOptions: showdown.ConverterOptions = {}

const converterOptions: showdown.ConverterOptions = { simpleLineBreaks: true }
