Vue.js 0.10 is here!
Mar 22, 2014
Vue.js 0.10.0 (Blade Runner) has been released! This release comes with many useful additions based on the suggestions from the users, notably interpolation in literal directives, dynamic components with the new v-view
directive, array filters, and the option to configure interpolation delimiters. Internally, the codebase has received many refactoring and improvements which makes Vue.js even faster.
See the Installation page for the latest builds.
New
- Literal directives can now contain interpolation tags. These tags will be evaluated only once at compile time. An example usage is conditionally decide which component to instantiate with
v-component="{{type}}"
. Doc. - Attributes listed in the
paramAttributes
option now accept mustache interpolations too. They will also only be evaluated once. v-repeat
now accepts an argument which will be used as the identifier for the wrapped object. This allows more explicit property access in repeaters. Doc.- Added
v-view
directive which binds to a string value and dynamically instantiate different components using that string as the component ID. Doc. - Added
filterBy
andorderBy
filters forv-repeat
. Doc. - Custom filters that access properties on its
this
context will be considered computed filters. Doc. - You can now access the event in
v-on
handler expressions as$event
. Example:<a v-on="click:handle('hello', $event)">Hello</a>
- Interpolation delimiters can now be customized via the
delimiters
global config option. Example:Vue.config({ delimiters: ["[", "]"] })
will change the matched interpolation tags to[[ ]]
for text bindings and[[[ ]]]
for html bindings.
Changed
{{>yield}}
syntax has been deprecated. A Web Components spec compatible content insertion mechanism using<content>
elements has been introduced. Doc.- To use a component as a custom element, the component ID must now contain a hyphen (
-
). This is consistent with the current custom element spec draft. v-repeat
Arrays’ augmented methods have been renamed fromset
to$set(index, value)
andremove
to$remove(index | value)
. The prefix better differentiates them from native methods. Thereplace
method has been removed.- When iterating over an Object with
v-repeat
, the object no longer gets a$repeater
array. Instead, the object is now augmented with two methods:$add(key, value)
and$delete(key)
, which will trigger corresponding view updates. v-if
now creates and destroys a child ViewModel instance when the binding value changes, instead of simply removing/inserting the DOM node. In addition, it can no longer be used withv-repeat
. Usev-show
or the new built-in array filters instead.v-with
can no longer be used alone. It now must be used with eitherv-component
orv-view
.v-component
can also be used as an empty directive just to create a child VM using the defaultVue
constructor.- Production build now strips all warnings and debug logs. To leverage
debug: true
, use the development version. The development version now has more detailed warning messages.
Fixed
event.stopPropagation()
andevent.preventDefault()
insidev-on
handlers now work as expected.parent
option now works properly when used inVue.extend
- Mustache bindings inside
<textarea>
are now properly interpolated before being set as value.
Internal
v-component
,v-with
andv-if
have been re-written for a cleaner compile flow.v-repeat
has been re-written to use refined diff algorithm which triggers minimum DOM manipulations when the array is set to a different instance containing overlapping elements. This makes it efficient to pipe an Array through filters.template
option now directly clones native<template>
‘s content when available.- Overall performance improvements for both initialization and rendering.
