v2.0.0-rc.0

After a long wait here it is, the first Release Candidate for vue-meta v2.0 which should resolve most outstanding issues. As v2 is mostly a refactor of v1, there are not many breaking changes and we expect to release v2 soon

Breaking Change

• The behaviour of keys with undefined as value has changed:
  • In v1 it would be rendered as a boolean attribute, but as boolean attributes are actually part of e.g. the html5 specifications this functionality has been removed
  • In v2 it can be used to render child properties conditionally.

See the docs for more information about boolean attribute handling and how to use child properties conditionally

Noteworthy Changes

• We now have a separate documentation website! https://vue-meta.nuxtjs.org
• The global mixin which vue-meta uses now only injects a beforeCreate lifecycle hook. Other lifecycle hooks will only be added when a component has a metaInfo property defined
• When retrieving and merging the metaInfo in your app, component branches without any component which defines metaInfo are skipped
• A refreshOnceOnNavigation option has been added which uses vue-router navigation guards to only trigger meta updates once after navigation. Also check the afterNavigation callback which can be used to run some script that relies on update metadata (e.g. page tracking)
• You have more control on which value is used when a parent and child define the same vmid. See the docs on special cases for more information

Migration Guide

If you want to help us test this release candidate, please follow these steps:

1. Manually update your vue-meta version

   1. E.g. update your package.json to read "vue-meta": "2.0.0-rc.0" (or use the next tag):
   2. Run npm install or yarn install

2. Change the boolean attributes you use to have a different value than undefined

3. Test and please report any issues you experience!
