How to post object with Set/Array field in typescript/angular

Question

I have class like:

export class LogModel {
..
componentSet: Set<string>;
constructor(componentSet: Set<string>) {
    this.componentSet = componentSet;
}

And I need to post this class to Spring boot app. But I have the problem with JSON deserialization because:

And I have to use transform method like

`private toArray(set) {
        let array: string[] = [];
        for (let i = 0; i < set.length; ++i)
            array[i] = set[i];
        return array;
    }`

in order to have How to properly POST this class?

So you want to convert Set to Array? Is this exactly you want? — Arpit Kumar

Do like this before sending to post method

const postValue = Array.from(this.componentSet);

(OR)

const setValues = this.componentSet.values();
const postValue = Array.from(setValues);

Then post the postValue

Array.from(this.componentSet) is sufficient.
