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
