The community plugins and components might need different strategies for different versions. In this case, you can use Vue.version which provides installed version of Vue as a string.
Example :
let version = Number(Vue.version.split('.')[0])
if (version === 2) {
// Vue v2.x.x
} else if (version === 1) {
// Vue v1.x.x
} else {
// Unsupported versions of Vue
}
