Render an order book for any asset class. Flexible and customizable.
react-order-book is a simple, flexible order book component. Pass in an order book as a prop, and cutomize the look and feel with plenty of configuration options, plus numerous styling hooks for visual customization.
react-order-book tries to be extremely unopinionated about styling, and as such, includes very little actual style rules. There's plenty of examples in the included demo website that show how you can use the rendered class names to create your own beautiful experiences.
This component is perfect for:
- Trading platforms
- Order entry systems
- Dashboards
- Written in TypeScript
- Small, simple, configurable, performant
- Maintained by a team of finance industry professionals

You can also run the demo locally. To get started:
git clone [email protected]:lab49/react-order-book.git
npm install
npm run storybooknpm install @lab49/react-order-bookimport { OrderBook } from '@lab49/react-order-book';
// This is a simple order book structure. There's an array
// of asks, and array of bids. Each entry in the array is
// an array where the first index represents the price,
// and the second index represents the "size", or the total
// number of units of an asset offered at that price.
const book = {
asks: [
['1.01', '2'],
['1.02', '3'],
],
bids: [
['0.99', '5'],
['0.98', '3'],
],
};
<OrderBook book={book} />As discussed above, there are a number of classnames you can use to add your own styles. There is an example of doing exactly that in the included Storybook. There's too many to list out, but by default, all DOM nodes have a classname prefixed with rob_OrderBook. As an example:
<OrderBook book={book} />
// Will render...
<div class="rob_OrderBook">
<div class="rob_OrderBook__side rob_OrderBook__side--asks">
// ...more content
</div>
<div class="rob_OrderBook__side rob_OrderBook__side--bids">
// ...more content
</div>
</div><OrderBook /> is a (props: Props) => JSX.Element. See Props below for a description of the avilable props.
import { OrderBook } from '@lab49/react-order-book';
const MyComponent = () => <OrderBook book={book} />;interface Props {
/**

/**

/**

*/

/**

*/
spread?: string;
/**

}Available layout modes. See the demo website for an example of what this looks like.
