Iterating through an array of objects to filter specific data

David Clelland

I am trying to get specific data filtered on an API call. The objects are not iterable and I have tried a million different ways to get the specific data I need.

So...I need to filter out tip_money and return only that data instead of the full response.

Here is the call

router.get('/', auth, (req, res) => {
    try {
        apiInstance.listPayments(opts).then(function (payments) {
            res.send(payments)
        })
    } catch (error) {
        console.error(error)
    }
});

and here is the response (partially):

{
    "payments": [
        {
            "id": "rt6Q8LL3XrCLGltl3bBhazMF",
            "created_at": "2019-11-12T23:34:03.012Z",

            },
            "processing_fee": [

                    }
                }
            ],
            "status": "COMPLETED",
            "source_type": "CARD",
            "card_details": {
                "status": "CAPTURED",
                "card": {
                    "card_brand": "VISA",

                    "exp_month": ,

                    "cardholder_name": "",

                "verification_method": "SIGNATURE",
                "verification_results": "UNKNOWN",
                "statement_description": ""
            },
            "location_id": "",
            "order_id": "",
            "employee_id": "DrU-af4--DVfMCkl2z73"
        },

any help in the right direction would be appreciated!

See if something like this works for you

router.get('/tips', auth, (req, res) => {
    try {
        apiInstance.listPayments(opts).then(function (payments) {
            const tips = payments.map(payment => payment.tip_money).filter(tip => tip != undefined);
            res.send(tips);
        })
    } catch (error) {
        console.error(error)
    }
});

Remove the .filter at the end if you also want the endpoint to return the undefined tips since it doesn't seem like all the payments have tips on them.
