How to make a global method in vuejs?

Question

JavaScript

Hello.
How can I make a method in vuejs that I can call from any component?
It's just that I use the same method in several components, and in order not to write it for each, can I somehow place it in a separate file?
And what is the best way to use it?

methods: {
        getAllCategories() {
            axios.get('/api/categories')
                 .then(res => this.categories = res.data)
                 .catch(err => console.log('Error'));
        }
    }

Thank you.
