ohlcv api

This is a simple API that provides ohlcv and live tick data.

The database holds immutable historical candle data. It is self-completing and sparse; that is, it does not know which tickers to care about, but once a user requests a symbol, it updates itself and then keeps itself updated.

Live data lives in memory only; that is, it does not persist through restarts. It also updates upon user request.

Development

To start the development server run:

bun run dev

Open http://localhost:3000/ with your browser to see the result.
