I used aws-sns to create one webhook. Two lambda functions are checked by this webhook. One of the lambda functions publishes 'orderId' and'startTime', while another publishes 'orderId' and 'roundName'. Both lambdas fire at different times. As a result, publishing can happen at two different times. One or both of the'startTime' and 'roundName' parameters may be undefined.
If 'roundName' exists, the 'updateOrder' variable will return 'roundName,' and the database will be updated. When'startTime' is set and 'roundName' is left blank, the 'roundName' will be rewritten from the database, which I don't want. Because if there is a 'roundName,' there will always be a 'roundName,' the value of 'roundName' can change but it will never be undefined.If startTime changes as well as roundName change then it will update the database. But my current logic is wrong. Struggling to implementing diffrent scenario logic.
const data = {
Records: [
{
Sns: {
Message:
'[{\n "orderId": "a4013438-926f-4fdc-8f6a-a7aa402b40ea",\n "roundName": "RO1"}]',
},
},
],
};
const existingData = [
{
modifiedAt: "2022-03-09T13:18:06.211Z",
lastMile: "progress",
createdAt: "2022-02-26T06:38:50.967+00:00",
orderId: "a4013438-926f-4fdc-8f6a-a7aa402b40ea",
},
];
// parse the data
const parseData = data.Records.flatMap((record) =>
JSON.parse(record.Sns.Message)
);
// check if the data exist or not
const existingOrder = existingData.filter(
(o1) => parseData.some((o2) => o1.orderId === o2.orderId)
);
// if there is no existingOrder then return false
if (existingOrder.length === 0) return;
// if there is exisiting order then add roundName and startTime from SNS event
const updateOrder = existingOrder.map((i) => {
const roundName = parseData.find((r) => {
return r.orderId === i.orderId;
}).roundName;
const startTime = parseData.find((r) => {
return r.orderId === i.orderId;
}).startTime;
return {
roundName: roundName ?? "",
startTime: startTime ?? "",
};
});
console.log(updateOrder);
