I have an object like this, that needs to be sent to an API -
var data = {
field : "category"
value : "order"
}
Now, this API also needs some conditions needed to be sent as nested objects. Something like this -
var data ={
field : "category"
value : "order"
AND : {
field : "circuit"
value : "ninth"
OR : {
field : "second"
value : "abc",
//more conditions here possible //
}
}
So, basically, a condition is nested inside a condition. EDIT:: Note - Each condition added into the conditions array has to be nested into the previous condition
Now, I have an array of conditions -
conditionsArray = [
{filter: "AND", field: "circuit", value: "ninth"},
{filter: "OR", field: "second", value: "abc"}
]
How do I add conditions to data object from this conditionsArray in the most optimal way?
var data = {
field : "category"
value : "order"
}
Thank you for your time.
EDIT: sorry, I forgot to add what I have tried so far -
I have been trying to just form an object but this is by no means a good solution.
const check = () => {
console.log(conditionsArray);
const data: any = { ...fieldValue };
conditionsArray.forEach((condition: any) => {
const { filter, name, value } = condition;
const { AND, OR, NOT } = data;
if (AND || OR || NOT) {
if (AND) {
data["AND"][filter] = { name, value };
}
if (OR) {
data["OR"][filter] = { name, value };
}
if (NOT) {
data["NOT"][filter] = { name, value };
}
} else {
data[filter] = { name, value };
}
});
console.log(data,"log data");
};
You could reduce the array and return the nested object for the next iteration.
const
data = { field: "category", value: "order" },
conditionsArray = [{ filter: "AND", field: "circuit", value: "ninth" }, { filter: "OR", field: "second", value: "abc" }];
conditionsArray.reduce((o, { filter, ...rest }) => o[filter] = rest, data);
console.log(data);
.as-console-wrapper { max-height: 100% !important; top: 0; }
Using recursion :
function addConditions(data, conditions) {
if (conditions.length == 0) { return data; }
var topMostCondition = conditions[0];
var objectToAdd = { field : topMostCondition.field, value : topMostCondition.value };
data[topMostCondition.filter] = addConditions(objectToAdd, conditions.splice(1));
return data;
}
