@shipengine/alchemy v6.0.38

Alchemy

shipengine/alchemy is a toolkit for building re-usable, fully-featured, data-connected and cross-compatible React components (“Elements”)^1 for use in applications that utilize the ShipEngine API.

The library makes opinionated choices about API access, state management, language translations^2 and UI foundations.

Features:

• Available to all descendants of the AlchemyProvider:

  • A batteries-included client for accessing ShipeEngine API endpoints with a shared cache and lifecycle management via hooks from @shipengine/react-api.
  • A ShipEngine Giger theme, which can be re-defined at instantiation via the themeConfig prop and accessible on the Emotion css callback prop, and icons via Giger's Icon component.

• Available to components created via the alchemy.createElement factory:

  • Fully isolated styles. CSS styles are reset at the boundary of each Element, ensuring that they are self-contained and unaffected by the host application’s styles.
  • Fully isolated language translations. A non-global instance of i18next is provided for each Element. Individual translations can be overriden at the Element's point-of-use via the optional resources prop.
  • A configurable ErrorBoundary.

Basic Usage

!IMPORTANT In addition to @shipengine/alchemy, you must also add @shipengine/react-api and @shipengine/js-api to your project's dependencies.

• A single AlchemyProvider should be rendered near the top of the application's component hiearchy
• The createElement factory is used to create stylistically isolated components that will utilize the AlchemyProvider's API client and theme.

import alchemy, { AlchemyProvider, useListShipments } from "@shipengine/alchemy";
import { themeConfig } from "../themeConfig";

type MyComponentProps = {
  myProp: string;
};

const MyComponent = ({ myProp }: MyComponentProps) => {
  const { data, isLoading, error } = useListShipments();

  if (isLoading) return <div>Loading...</div>;
  if (error) return <div>{error.message}</div>;

  console.log(data);
  // > an object matching the response schema of https://shipengine.github.io/shipengine-openapi/#operation/list_shipments

  return (
    <div
      css={(theme) => ({
        /* ... */
      })}
    >
      Retrieved {data.shipments.length} shipments
    </div>
  );
};

// Your own component that the ErrorBoundary will display when an error occurs
const MyErrorFallback = ({ error }) => <div>Whoops...</div>;

const MyElement = alchemy.createElement(
  MyComponent,
  MyErrorFallback,
  // optional configuration object
  {
    // applied to the container
    css: (theme) => ({
      // ...
    }),

    // i18next translations
    resources: {
      // ...
    },
  }
);

const MyApp = () => {
  return (
    <AlchemyProvider getToken={() => "your-platform-token"} themeConfig={themeConfig}>
      <section>
        Your pre-existing application
        <div>
          Locate the Element wherever you like
          <MyElement
            myProp="just a regular prop"
            // optional translations override prop added by the factory
            resources={{}}
          />
        </div>
      </section>
    </AlchemyProvider>
  );
};
