v0.6.1

Fix

• __DEV__ is not defined, #355, @yoyo930021

v0.6.0

Great thanks to @pikax for #311, making most of the APIs better aligned with the latest vue-next.

BREAKING CHANGE

• The lazy option of watch has been replaced by the opposite immediate option, which defaults to false. (It's ignored when using the effect signature). more details (#266)
• Rename nonReactive to markRaw
• watchEffect now follows the same behaviour as v3 (triggers immediately).
• UnwrapRef types from vue-next this can cause some incompatibilities.

Bug Fixes

• Added missing reactivity API from vue-next, #311, @pikax
• Fix return type of toRefs, #315
• Fix incorrect ref typing, #344, @antfu
• Binding context vm when using function without parentheses, #148, @pikax
• computed: destroy helper vm of computed to prevent memleak, #277, @LinusBorg
• Remove the surplus Function type from PropType, #352, @pikax

Features

• Added unref(#309), isReactive (#327), toRef (#313), UnwrapRef (#247)
• Added shallowReactive, shallowRef
• Added toRaw
• getCurrentInstance available on the lifecycle hooks (onMounted, etc)
• getCurrentInstance returns undefined when called outside setup instead of throwing exception

Changed

The render function returned from setup no longer receives any parameters.

Previous

export default {
  setup() {
    return props => h('div', prop.msg);
  },
};

Now

export default {
  setup(props) {
    return () => h('div', prop.msg);
  },
};

v0.2.1

• Declare your expected prop types directly in TypeScript:

  import { createComponent, createElement as h } from '@vue/composition-api'
  
  interface Props {
    msg: string
  }
  
  const MyComponent = createComponent<Props>({
    props: { 
       msg: {}  // required by vue 2 runtime
    },
    setup(props) {
      return () => h('div', props.msg)
    }
  })

• Declare ref type in TypeScript:

  const dateRef = ref<Date>(new Date);

• Fix createComponent not working with import() #81.
• Fix inject type declaration #83.
