The biggest blocker to upgrading to Vue 2 is the fact that Vue 2 does not support
$dispatch methods, and Vue 2 doesn't come with a drop-in
replacement for them. This package is that replacement.
It is important to remember that there is a good reason that Vue 2 dropped these methods. To quote the upgrade guide:
The problem is event flows that depend on a component's tree structure can be hard to reason about and very brittle when the tree becomes large. It simply doesn't scale well and we don't want to set you up for pain later. $dispatch and $broadcast also do not solve communication between sibling components.
All this is true. But that doesn't solve the problem of legacy codebases which already have a serious amount of functionality implemented this way. It's a shame for this one thing to block you from upgrading to the newest version of Vue.
npm install --save vue-oldstyle-events
But if, like me, you have a codebase that because of this feature is still stuck on Vue 1, then this plugin can help you upgrade to Vue 2 without rewriting all of your event-based logic.
