FAQ

Compare to vue-global-api

You can think of this plugin as a successor to vue-global-api, but offering much more flexibility and bindings with libraries other than Vue (e.g. React).

Pros

• Flexible and customizable
• Tree-shakable (on-demand transforming)
• No global population

Cons

• Relying on build tools integrations (while vue-global-api is pure runtime) - but hey, we have supported quite a few of them already!
