runtime-dom: Only props starting with
on
followed by an uppercase letter or a non-letter character are considered event listeners. -
runtime-core: this.$emit() and setupContext.emit() no longer return values. For logic that relies on return value of listeners, the listener should be declared as an
onXXX
prop and be called directly. This still allows the parent component to pass in a handler usingv-on
, sincev-on:foo
internally compiles toonFoo

. The motivation of the original change was avoiding unnecessary deep conversions, but that can be achieved by explicitly marking values non-reactive viamarkNonReactive
.Removing the reactive conversion behavior leads to an usability issue in that plain objects containing refs (which is what most composition functions will return), when exposed as a nested property from
setup()
, will not unwrap the refs in templates. This goes against the "no .value in template" intuition and the only workaround requires users to manually wrap it again withreactive()
.So in this commit we are reverting to the previous behavior where objects returned from
setup()
are implicitly wrapped withreactive()
for deep ref unwrapping.

reactivity: reactive arrays no longer unwraps contained refs
When reactive arrays contain refs, especially a mix of refs and plain values, Array prototype methods will fail to function properly - e.g. sort() or reverse() will overwrite the ref's value instead of moving it (see #737).
Ensuring correct behavior for all possible Array methods while retaining the ref unwrapping behavior is exceedingly complicated; In addition, even if Vue handles the built-in methods internally, it would still break when the user attempts to use a 3rd party utility function (e.g. lodash) on a reactive array containing refs.
After this commit, similar to other collection types like Map and Set, Arrays will no longer automatically unwrap contained refs.
The usage of mixed refs and plain values in Arrays should be rare in practice. In cases where this is necessary, the user can create a computed property that performs the unwrapping.

BREAKING CHANGES
-
watch:
watch
behavior has been adjusted.-
When using the
watch(source, callback, options?)
signature, the callback now fires lazily by default (consistent with 2.x behavior).Note that the
watch(effect, options?)
signature is still eager, since it must invoke theeffect
immediately to collect dependencies. -
The
lazy
option has been replaced by the oppositeimmediate
option, which defaults tofalse
. (It's ignored when using the effect signature) -
Due to the above changes, the
watch
option in Options API now behaves exactly the same as 2.x. -
When using the effect signature or
{ immediate: true }
, the initial execution is now performed synchronously instead of deferred until the component is mounted. This is necessary for certain use cases to work properly withasync setup()
and Suspense.The side effect of this is the immediate watcher invocation will no longer have access to the mounted DOM. However, the watcher can be initiated inside
onMounted
to retain previous behavior.

related API signatures (c07751f) - remove implicit reactive() call on renderContext (6b10f0c)
Performance Improvements
- ssr: avoid unnecessary async overhead (297282a)
BREAKING CHANGES
-
object returned from
setup()
are no longer implicitly passed toreactive()
.The renderContext is the object returned by
setup()
(or a new object if no setup() is present). Before this change, it was implicitly passed toreactive()
for ref unwrapping. But this has the side effect of unnecessary deep reactive conversion on properties that should not be made reactive (e.g. computed return values and injected non-reactive objects), and can lead to performance issues.This change removes the
reactive()
call and instead performs a shallow ref unwrapping at the render proxy level. The breaking part is when the user returns an object with a plain property fromsetup()
, e.g.return { count: 0 }
, this property will no longer trigger updates when mutated by a in-template event handler. Instead, explicit refs are required.This also means that any objects not explicitly made reactive in
setup()
will remain non-reactive. This can be desirable when exposing heavy external stateful objects onthis
. -
createApp
API has been adjusted.createApp()
now accepts the root component, and optionally a props object to pass to the root component.app.mount()
now accepts a single argument (the root container)app.unmount()
no longer requires arguments.
New behavior looks like the following:
const app = createApp(RootComponent) app.mount('#app') app.unmount()
