Demoparser is a tool for analysing CS2 replay files "demos". All the heavy lifting is done in Rust, but you use it from the comfort of Python/JavaScript. The parser takes a slightly different approach to exposing the information in the demo. Rather than letting you hook onto events in a streaming fashion, it lets you "query" the demo similarly to how you would interact with a database.
Python: pip install demoparser2
NodeJS: npm i @laihoe/demoparser2
from demoparser2 import DemoParser
parser = DemoParser("path_to_demo.dem")
event_df = parser.parse_event("player_death", player=["X", "Y"], other=["total_rounds_played"])
ticks_df = parser.parse_ticks(["X", "Y"])var {parseEvent, parseTicks} = require('@laihoe/demoparser2');
let event_json = parseEvent("path_to_demo.dem", "player_death", ["X", "Y"], ["total_rounds_played"])

Without Dotabuff's dota 2 parser "manta" this would not have been possible. Check it out: https://github.com/dotabuff/manta
The dota 2 demo format is very similar to CS2 demo format with only a few minor changes.
