In NGXS , I need to set the new element in "items: any[]" the first index of an array every time. something like (unshift)
Example:
items[] = [{'aa':val},{'bb':val}]
Now Am inserting {'cc':val} Then expected array should be like
items[] = [{'cc':val}, {'aa':val},{'bb':val}]
Declaration
export class BasketStateModel {
public **items: any[]**;
public basketSize: number;
}
BASKET ACTION
const state = getState();
setState({ items: **[...state.items, payload]**, basketSize: state.items.length + 1 });
}
This is how you can insert element(s) at first place in array :
let myArr = [{'a':'a'},{'b':'b'}]
myArr = [{'c':'c'}, ...myArr]
console.log(myArr)
