I want to create a function that takes arguments from few sources, and returns a promise with new object.
So, I have a base object that holds all the data, also have another function that takes one of the params and do some manipulation and returns another data.
The main problem is I have some race-conditions or the new object not changing as wanted, maybe because the nested functions.
I tried to look at other answers but no success.
Enough with intro, here's some of my code:
imports...
const createNewObject = async () => {
try {
const baseObjFromRequest = await myClient.request(query); // Returns array of objects
// this is the base object structure that returns from request:
baseObjFromRequest = [
{data: "some data x", val: 1},
{data: "some data y", val: 8},
{data: "some data z", val: 7},
{data: "some data x", val: 3},
{data: "some data z", val: 11},
]
// the pipeline should iterate over the array, with the converter function
// and return the info as the key of the new object
// which key is a counter of the values
newObject = {}
baseObjFromRequestAbove.forEach(item => {
let keyFromConverter = converter(item.data);
newObject[keyFromConverter] += item.val;
})
// Now I want to return new object (as promise)
// in this structure, but somehow it breaks any time and not return it as well.
newObject = {
info_from_x: 4, // The value is the count of
info_from_y: 8,
info_from_z: 18,
}
return newObject; // As promise
} catch (error) {
console.error(err);
}
}
// This function do a call and convert the data to new info data
const converter = async (data) => {
let query = { "info": data }
try {
const resp = await axios.post(URL + '/info', query);
const data = await resp.data;
return data;
} catch (err) {
console.error(err);
}
};
