TradingView's Lightweight Charts is a compact (~35 KB) TypeScript library for rendering fast, interactive financial charts (candlestick, line, area, etc.) using HTML5 canvas. It supports real-time streaming data updates and extensibility via a plugin system.
Use cases
- display candlestick stock charts on a web page
- render interactive price charts for a crypto dashboard
- replace static chart images with lightweight interactive charts
- show real-time streaming market data in a browser
- embed performant financial time-series charts in a trading app
- build custom chart indicators with a plugin API
When to choose
- you need small bundle size and high rendering performance for financial charts
- you want TradingView-style candlestick or line charts in a web app
- you need real-time updates without page reloads
- you want an Apache-2.0 licensed, actively maintained charting library
When to avoid
- you need general-purpose scientific or statistical charts rather than financial ones
- you need server-side rendering of charts to images
- you need heavy built-in technical indicators or drawing tools out of the box
- you need charts for non-time-series data like pie or bar category charts
