how to access object data within object-CodePudding

I have this:

const paymentIntents = await stripe.paymentIntents.list({
    stripeAccount: stripe_account
});

and it returns:

object: 'list',
  data: [
    {
      id: 'pi_...',
      object: 'payment_intent',
      amount: 2500,

now I have two problems. 1. I need to access amount. and 2. there is going to be dozens of records being returned, so I need to loop through all the results and actually add up the amounts. here's what I've tried so far:

console.log(paymentIntents.amount)
console.log(paymentIntents.data.amount)

neither of those worked. and i wouldn't even know how to loop thorugh all those results. How can i do this?

CodePudding user response：

you can use reduce like this:

const paymentIntents = {object: 'list', data: [{
      id: 'pi_...',
      object: 'payment_intent',
      amount: 2500}, {
      id: 'pi_...',
      object: 'payment_intent_2',
      amount: 3500,
}]}
const amount = paymentIntents.data.reduce((previous, current, index, array) => {  
 const sum = current.amount   previous.amount; 
 return sum; 
});

const paymentIntents = await stripe.paymentIntents.list({
    stripeAccount: stripe_account
});

const total = paymentIntents.data.reduce(
  (listTotal, line) => listTotal   line.amount,
  0
);

CodePudding user response：

Be aware that if you expect to come close to the limit of 100 results for a list request, you should make sure to handle pagination, for example using the autopagination supported by stripe-node:

let total = 0
stripe.paymentIntents.list({limit: 5})
  .autoPagingEach(function(pi) {
    total  = pi.amount
  });

Note that this structure requires iteration, and precludes the use of reduce-type solutions in the other answers. If your expected result set won't come close to the 100 item limit, then set your limit appropriately and don't worry about this.
