Vue ajax file upload

Hi. I am trying to upload a file using vue.js,

The code below works as it's supposed to, but I am wondering if I am missing something else.

Please let me know if there is a better way or more secure way to do this.

<input type="file" ref="file" @change="uploadFile" name="file">

methods: {
        uploadFile () {
            let data = new FormData;

            data.append('file', this.$refs.file.files[0]);

            if(this.$refs.file.files.length > 0) {
                axios.post(this.url, data)
                    .then( (response) => {
                        console.log(response)
                    })
            }
        }
    },
