FAQ

Compare to vue-global-api

You can think this plugin as a successor of vue-global-api, which offers much more flexibility and it's no longer bound to Vue exclusively. Now you can use it with any libraries you want (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!
