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
}
})
...
