Introduction

React Server Components (RSC) is a new way to build server-rendered applications with React. It is a set of experimental tools that enables developers to run React components on the server. RSC is a new way to build server-rendered applications with React.

​
Getting Started

Using server actions with existing graphQL mutations and queries works well and moves away from wrapping the app / layout file in a context provider / using hooks provided by apollo-client.

The idea is we can have a server component link to the graphQL endpoint and the server actions can be called directly from the UI. This moves away from either needing to using axios from a React Class Component, or using the API routes to make a request that needs to be returned to the client.


export const closeReturnAction = async (returnId: string): Promise<String | undefined> => {

    try {
        await closeReturn(returnId);
    } catch (e) {
        return 'Error closing return';
    }
};

export const reopenReturnAction = async (returnId: string): Promise<String | undefined> => {

    try {
        await reopenReturn(returnId);
    } catch (e) {
        return 'Error reopening return';
    }
};


export const cancelReturnAction = async (returnId: string): Promise<String | undefined> => {

    try {
        await cancelReturn(returnId);
    } catch (e) {
        return 'Error closing return';
    }
};

We can build upon the GraphQL library of mutations, queries and fragments we have made and adopt this new architecture which is modular and type safe throughout.

This allows us to move quickly and have the best of server rendered data with client side interactiveness depending on the use case.

​
StateSet Fetch


export async function getReturn(returnId: string): Promise<Return | undefined> {

  const res = await statesetFetch<StatesetReturnOperation>({
    cache: 'no-store',
    query: getReturnQuery,
    variables: { returnId },
  });

  return res.body.data.returns_by_pk;
}

We can now fetch the individual return data using /return/[id]/page.tsx which is a server component. This makes an aysnc call to the Stateset One GraphQL API on Stateset Cloud which we have typed return operators for.


export type StatesetReturnOperation = {
  data: {
    returns_by_pk: Return
  };
  variables: {
    returnId: string;
  };
};

We are already starting to see the benefits of using this pattern in that we can still have the declarative side of GraphQL but we have a much cleaner approach than have queries stored on each JS file. We can keep all of them in ‘lib/stateset’ and import them to the server actions files that we need.


export const getReturnQuery = /* GraphQL */ `
query getReturn($returnId: String!) {
  returns_by_pk(id: $returnId) {
      ...return
    }
  }
  ${returnFragment}
`;

export const getReturnsQuery = /* GraphQL */ `
    query getReturns(
        $limit: Int
        $offset: Int
        $order_direction: order_by
    ) {
        returns(limit: $limit, offset: $offset, order_by: {created_date: $order_direction}) {
          ...return
    }
  }

    ${returnFragment}
  `;

​
Fragments

We can also use fragments to keep the queries clean and modular. This is a great way to keep the queries clean and also to keep the types consistent across the application.


export const returnFragment = /* GraphQL */ `
  fragment return on returns {
    id
    created_date
    amount
    action_needed
    condition
    customerEmail
    customer_id
    description
    enteredBy
    flat_rate_shipping
    order_date
    order_id
    reason_category
    reported_condition
    requested_date
    rma
    serial_number
    scanned_serial_number
    shipped_date
    status
    tax_refunded
    total_refunded
    tracking_number
    warehouse_received_date
    warehouse_condition_date
    refunded_date
  }
`;

​
Server Actions

We can now use the server actions to call the GraphQL API and return the data to the server component. This is a great way to keep the queries clean and also to keep the types consistent across the application.


export async function getReturns({
  limit,
  offset,
  order_direction
}: {
  limit?: number;
  offset?: number;
  order_direction?: string;
}): Promise<Return> {
  const res = await statesetFetch<StatesetReturnsOperation>({
    query: getReturnsQuery,
    variables: {
      limit,
      offset,
      order_direction
    },
    cache: 'no-store'
  });

  return res.body.data.returns;
}


export async function getReturn(returnId: string): Promise<Return | undefined> {

  const res = await statesetFetch<StatesetReturnOperation>({
    cache: 'no-store',
    query: getReturnQuery,
    variables: { returnId },
  });

  return res.body.data.returns_by_pk;
}

​
Server Component to the Client

We can now use the server component to fetch the data and return it to the client. This is a great way to keep the queries clean and also to keep the types consistent across the application.


export default function ReturnPage({ returnId }: { returnId: string }) {

  const [returnData, setReturnData] = useState<Return | undefined>(undefined);

  useEffect(() => {
    const getReturn = async () => {
      const res = await getReturnAction(returnId);
      setReturnData(res);
    };
    getReturn();
  }, []);

  return (
    <>
      <TopBar />
      <div className="flex">
        <Sidebar />
        <div className="flex-1">
          <div className="px-4 mt-8 md:px-20 lg:px-32 space-y-4">
            <ReturnAnalytics returns_month={100} returns_today={5} />
          </div>
          <div className="mt-8 px-4 md:px-20 lg:px-32 space-y-4">
            <AdvancedReturnTable returns={returnData} offset={0} limit={20} />
          </div>
        </div>
        <div className="mt-8 px-4 md:px-20 lg:px-32 space-y-4">
            
        </div>
      </div>
    </>
  );
}
