Combine various objects into an array and ensure that any modifications are coordinated

Recently, I integrated a third-party component called <datetime-picker> into my project. This component requires a Date[] of size 2 as its v-model in order to set a range of time. However, in my existing codebase, I have been using two separate Date objects for the start and end times, named startTime and endTime, respectively. I would prefer to continue using this structure.


        // in my previous codebase (class-based Vue component)
        private startTime = new Date();
        private endTime = new Date();
        
        // However, now I am forced to store the values in an array for the third-party component
        private dateTimeRange = [this.startTime, this.endTime];
    

Unfortunately, simply passing dateTimeRange to the <datetime-picker> won't work as expected, as the array's reference will get overwritten during updates.


        <datetime-picker v-model="dateTimeRange" ... />
    

I am looking for an elegant solution to ensure that any changes made by the datetime picker component are properly reflected back to the startTime and endTime objects.

Answer №1

Here is a suggested approach to try:

  1. private dateTimeRange = [new Date(), new Date()];
    --> replacing complex references with a "proxy" instance variable.

  2. Implement a computed or property accessor to fetch and display both values:

    private get dateRange(): NiceType {
        return {start: this.dateTimeRange[0], end: this.dateTimeRange[0]}
    }
