EnglishWhere to Find TechanJS Documentation, Source Code, and Examples
Updated
TechanJS is a financial charting and technical analysis library built on D3. Its official site, techanjs.org, is the primary hub for everything you need to get started: the home page, documentation, source code, examples, and chart source. From the site's own navigation, you can reach the documentation, browse the source, and open working examples that demonstrate candlestick, OHLC, volume, moving averages, Ichimoku Cloud, RSI, and MACD charts. If you are evaluating or beginning with TechanJS, start at techanjs.org and work through the Documentation and Examples entries in that order.
The main entry points on techanjs.org
The site presents a small set of navigation links that map directly to what a new user needs:
| Entry | What it gives you |
|---|---|
| Home | Overview of the library and its purpose |
| Documentation | Reference material for using the library |
| Source | Access to the project source code |
| Examples | Working chart and indicator demonstrations |
| Chart Source | Source for the chart examples |
| Download | Getting the library for use in your project |
The site describes TechanJS as "a visual, stock charting (Candlestick, OHLC, indicators) and technical analysis library built on D3," and its stated goal is to help you "build interactive financial charts for modern and mobile browsers."
What the examples cover
The examples are the fastest way to understand what the library can render. According to the site, the supported chart and indicator set includes:
- Candlestick
- OHLC
- Volume
- Moving Average (Simple & Exponential)
- Ichimoku Cloud
- RSI
- MACD
- Trades
There is also a "Complete Example" that combines elements. If you are new to the library, open the individual examples first to see each chart type in isolation, then look at the Complete Example to see how pieces fit together.
How to get the library
The site provides a Download entry alongside Documentation, Source, and Examples. Use Download to obtain the library for your project, and use Source if you want to read or build from the code itself. The site does not state pricing or licensing terms beyond a link labeled "TechanJS License," so check that link directly if licensing matters for your use.
A practical way to start
- Open techanjs.org and read the Home overview to confirm the library fits your charting needs.
- Go to Documentation for the API reference.
- Open Examples and run through candlestick, OHLC, and one indicator such as RSI or MACD.
- Use Chart Source to see how those examples are constructed.
- Download the library, or go to Source if you prefer to work from the repository.
Because TechanJS is built on D3, familiarity with D3 concepts helps when reading the examples and adapting them. The site's own framing is that it is built on D3, so expect D3-style patterns in the chart source.
