TradingView Data Feed JS

A lighweight websocket client for accessing tradingView candlestick data via Node.js. Inspired by tvdatafeed for python - But made for JavaScript Devs, crypto traders and bot builders. This is just what could be.

What This Project Solves

I build a lot of bots and tools that rely on TradingView data, and honestly, it's always been a pain. Every time I needed that data, I had to switch over to Python just to use tvdatafeed. It felt like a long detour for something that should've been simple — especially since most of my projects are in JavaScript or Node.js.

There wasn’t a solid npm package (at least not that I could find) that gave me what I needed. That always forced me to either rewrite parts of my project in Python or come up with ugly workarounds.

The day I finally used this package to fetch TradingView data directly from Node.js, it just clicked. I felt at peace. No hacks, no switching languages — just clean JavaScript doing what I needed it to do.
