Retrieving a JSON document

We can perform the retrieval operation using the find method on a selected collection. Let us perform this operation by continuing with the add customers functionality and providing a list of already added customers on successful response. So, to demonstrate it, consider the following code:

{
    method: 'POST',
    path: '/customer/add',
    handler(request, h){
        const dbInstance = request.dbInstance;
        const requestBody = request.payload;
        const customerCollection = dbInstance.collection('customer');
        return customerCollection.insert(requestBody)
            .then((insertedStatus) =>{
                return customerCollection.find(
                    {})
                    .toArray()
                    .then((customerList) =>{
                        return {
                            message: "customer added successfully",
                            customerList
                        }
                    })
         ...
