From 030d02ca0f67782629dc602f2f441a8712f78bb7 Mon Sep 17 00:00:00 2001 From: pikax Date: Tue, 4 Aug 2020 19:07:06 +0100 Subject: [PATCH] feat: `proxyRefs` method and `ShallowUnwrapRefs` type BREAKING CHANGE: template auto ref unwrapping are now applied shallowly, i.e. only at the root level. See https://github.com/vuejs/vue-next/pull/1682 for more details. --- README.md | 11 +++ src/apis/state.ts | 2 + src/component/componentProxy.ts | 8 +- src/mixin.ts | 18 ++-- src/reactivity/index.ts | 3 +- src/reactivity/ref.ts | 42 +++++++-- src/reactivity/unwrap.ts | 56 ------------ test-dts/defineComponent.test-d.ts | 2 +- test/setup.spec.js | 132 ++++++++++++++++------------- 9 files changed, 135 insertions(+), 139 deletions(-) delete mode 100644 src/reactivity/unwrap.ts diff --git a/README.md b/README.md index b3af1efc..744e566d 100644 --- a/README.md +++ b/README.md @@ -392,6 +392,17 @@ app2.component('Bar', Bar) // equivalent to Vue.use('Bar', Bar) +### props +
