v2.2.0

A React hook which allows you to execute a GraphQL query lazily.

Example

import { useLazyQuery } from '@vendure/admin-ui/react';
import { gql } from 'graphql-tag';

const GET_PRODUCT = gql`
   query GetProduct($id: ID!) {
     product(id: $id) {
       id
       name
       description
     }
   }`;
type ProductResponse = {
    product: {
        name: string
        description: string
    }
}

export const MyComponent = () => {
    const [getProduct, { data, loading, error }] = useLazyQuery<ProductResponse>(GET_PRODUCT, { refetchOnChannelChange: true });

   const handleClick = () => {
        getProduct({
             id: '1',
        }).then(result => {
            // do something with the result
        });
    };

    if (loading) return <div>Loading...</div>;
    if (error) return <div>Error! { error }</div>;

    return (
    <div>
        <button onClick={handleClick}>Get product</button>
        {data && (
             <div>
                 <h1>{data.product.name}</h1>
                 <p>{data.product.description}</p>
             </div>)}
    </div>
    );
};
