Upload image need to refresh using $emit / $on in Vue - vue.js

Question

I have a method that calls the user data via axios
// method name getUser()
const user = await axios.get(`/user/${this.id}`)
this.id = user.data.data.id
this.name = user.data.data.name
this.email = user.data.data.email
I then use that in the mounted so if user visits /profile/id
it'll load the user data
mounted() {
this.getUser()
}
I tried to upload an image and I emit the event using global event bus once the image is successfully uploaded.
this.$event.$emit('IMAGE_UPLOAD')
Then catch that on the mounted too
mounted () {
// if I remove this it works, but I need to preload the data of the user
this.getUser()
this.$event.$on('IMAGE_UPLOAD', () => {
this.getUser()
})
}
my problem is it doesn't change the image meaning I still need to refresh the page if I call the this.getUser() too inside the mounted.
So I'm wondering how to work around this.
Thanks!

Since the url and name of the image does not change when the new image is uploaded the image in the browser is not updated. So what I have done in the past is a little trick to essentially change the url to the image by adding a unique query parameter. So use a data property for the location of your user image and in your method where you update the users data also update the img url and add something unique to the query parameter. I usually use new Date().getTime(). So you will end up with something like /img/user-xxxx.png?1559289852686
data(){
userImg: '/img/user-xxxx.png'
},
methods:{
getUser(){
//... get your user data
.then((data)=>{
this.userImg = data.user.img +'?'+ new Date().getTime();
})
}
