VueJS HTTP request error 500 Handling

Question

I am having this problem where I make HTTP Request to the API and in case of error ( specially error 500) the JS just breaks or goes into infinite loop and I should close the window and re-open the page. What I need is a message to pop up and in very generic way explain what happened. How should I handle this kind of error any ideas?

Example Request:

this.$http.get('people', { params }).then(({ data }) => {

            this.setFetching({
                fetching: false
            })
        })

Answer 1

then accepts a second callback to handle errors. You can also supply a .catch in addition to a .then to handle more severe failures.

 new Vue({ el: '#app', data: { fetching: true }, mounted() { this.$http.get('people') .then(() => { this.setFetching({ fetching: false }) }, (err) => { console.log("Err", err); }) .catch((e) => { console.log("Caught", e); }) } });
