Issue with Vue.js devtool not appearing in browser

Currently, I am integrating moment.js into a Vue component but I am facing an issue where certain changes are not being reflected in vue devtools.

Here is an example of my code:

export default {
    data() {
        return {
            moment: moment(),
        };
    },
    methods: {
        prevMonth() {
            this.moment.subtract(7, 'days');
        },
        nextMonth() {
            this.moment.add(7, 'days');
        }
    }
};

I suspect that the problem lies in calling a method on my moment data property rather than directly manipulating it like a number. For instance, when I use a similar approach with a count variable, it works seamlessly and updates in vue devtools:

export default {
    data() {
        return {
            count: 0,
        };
    },
    methods: {
        prevMonth() {
            this.count--;
        },
        nextMonth() {
            this.count++;
        }
    }
};

Is there a way to refresh or display these changes in vue devtools?

Answer №1

Vue may struggle to detect specific changes within an object, so it's important to review this detailed explanation in the official documentation for a better understanding.

To achieve your goal, consider creating a new date based on your current one using the prevMonth/nextMonth methods and assigning it to this.moment, like this:

prevMonth() {
    this.moment = moment(this.moment).subtract(1, 'month');
},
