DXJS is my first ever public library. I made it to help learn the process of publishing to NPM and gain experience with the entire development process from start to finish.

The library allows you to easily roll any arbitrary TTRPG dice, from a common d20 to a bespoke "weather" dice.

By utilizing an intermediary Abstract Syntax Tree (AST), the library can parse a string into individual dice rolls and breakdown the output.

This allows users to perform simple actions like roll("d20") or more complicated ones like roll("2d6+4d4+2") and get the results in a structured format.

Users can even add their own dice: javascript new Dice("weather", ["sun", "rain", "snow", "wind", "fog", "hail", "thunder", "lightning", "clouds", "clear skies"]); roll("weather")

Over the years it had features added including weightings and modifiers and has recently had a complete rewrite in Typescript.
