fix#2225
The previous props/emits normlaization was caching normalized result per
app instance, but during SSR there is a new app instance created for
every request.
The fix now de-opts props/emits normlaization caching when there are
props/emits declared in global mixins - which is a very rare use case.
returned from `defineComponent`
ref: https://github.com/vuejs/vue-router-next/pull/421
also close#1880
Previous `Component` type is now exported as `ConcreteComponent`.
This introduces a minor breaking change when calling `h(comp, { ... })`
will now fail if `comp` is a of generic `Component` type, since it does
not specify what props it expects.
e.g. by replacing `__VUE_OPTIONS_API__` to `false` using webpack's
`DefinePlugin`, the final bundle will drop all code supporting the
options API.
This does not break existing usage, but requires the user to explicitly
configure the feature flags via bundlers to properly tree-shake the
disabled branches. As a result, users will see a console warning if
the flags have not been properly configured.
BREAKING CHANGE: Reactivity APIs adjustments:
- `readonly` is now non-tracking if called on plain objects.
`lock` and `unlock` have been removed. A `readonly` proxy can no
longer be directly mutated. However, it can still wrap an already
reactive object and track changes to the source reactive object.
- `isReactive` now only returns true for proxies created by `reactive`,
or a `readonly` proxy that wraps a `reactive` proxy.
- A new utility `isProxy` is introduced, which returns true for both
reactive or readonly proxies.
- `markNonReactive` has been renamed to `markRaw`.
BREAKING CHANGE: adjust attr fallthrough behavior
Updated per pending RFC https://github.com/vuejs/rfcs/pull/137
- Implicit fallthrough now by default only applies for a whitelist
of attributes (class, style, event listeners, a11y attributes, and
data attributes).
- Fallthrough is now applied regardless of whether the component has
explicitly declared props. (close#749)
Store the keys for props that need default or boolean casting
during normalization, so that later we only need to iterate
through this array instead of the entire props object.
