Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

A complete trading chart for the web. Candlesticks to Renko, 134 indicators, 69 drawing tools, live feeds and orders on the chart, on Canvas 2D or WebGL, with no third-party dependencies. Use the full ChartWidget, or build your own interface on the headless Chart, in TypeScript, React, Vue or Svelte.

Highlights

  • 18 chart types, 134 indicators, 69 drawing tools, indicators on indicators, alerts on lines, undo and redo.
  • Trading on the chart: positions with live P&L, orders and stops you drag, a paper broker or your own.
  • Live data from Binance, Bybit, Coinbase and Kraken, or your own feed in about twenty lines.
  • Fast: a million bars panned at 60 fps with WebGL; a live tick in about a microsecond.
  • A workspace: grids of charts, layouts, bar replay, backtesting.
  • Yours to shape: themes, four looks, 132 switches, plugins; 30 languages; phones and apps.

Quick start

npm install @tradecanvas/chart
import { ChartWidget } from '@tradecanvas/chart/widget'
import { BinanceAdapter } from '@tradecanvas/chart'

new ChartWidget(document.getElementById('chart')!, {
  symbol: 'BTCUSDT',
  timeframe: '5m',
  theme: 'dark',
  adapter: new BinanceAdapter(), // live data, no API key
  trading: true,
})

The headless Chart takes your own bars (chart.setData(bars)) and leaves the interface to you. For React, Vue and Svelte, @tradecanvas/react, /vue and /svelte wrap it in a component with the same props.

Documentation

Getting started · API · Indicators · Drawing tools · Realtime · Trading · Styling · Frameworks · Plugins · Phones and apps · Performance

The docs are in English, Tiếng Việt, 简体中文, 日本語, 한국어 and Español. Measurements, limits and how it is tested are on the system audit.

AI coding tools

The agent skill in skills/tradecanvas teaches coding agents the API, with examples that CI type-checks. In Claude Code:

/plugin marketplace add bonguynvan/tradecanvas
/plugin install tradecanvas@tradecanvas

Other agents (Cursor, Codex, Copilot and more): npx skills add bonguynvan/tradecanvas. Without a skill, llms.txt and llms-full.txt give an assistant the docs in one file. Changing TradeCanvas itself with an agent? AGENTS.md holds the repo's rules.

The MCP server @tradecanvas/mcp looks up indicators, drawing tools, options, feature switches and style keys in the library's own catalog, and checks an options object before it is used (set it up in other clients):

claude mcp add tradecanvas -- npx -y @tradecanvas/mcp

On Windows outside WSL: claude mcp add tradecanvas -- cmd /c npx -y @tradecanvas/mcp. In Git Bash, which runs the ! commands of Claude Code on Windows, write //c: Git Bash turns /c into a path.
