Features

Refined Autocomplete for Component Props

Previously, we inferred props used for autocomplete from the component itself's type, which did not work well with components whose props need to be inferred dynamically, such as generics or discriminated unions.

Now, we have improved this feature to better align with TS behavior. See the following example:

<script lang="ts" setup>
  defineProps<
    | { type: "foo"; foo: string }
    | { type: "bar"; bar: string }
  >();
</script>

<template>
  <Self type="foo" :| />
  <!--              ^ [foo, ...] -->
  <Self type="bar" :| />
  <!--              ^ [bar, ...] -->
</template>

When triggering completions at the two positions above, we will now get the props that are actually available in each corresponding case.

(PR: #5709)

Check Required Fallthrough Attributes

Consider the following structure:

<!-- basic.vue -->
<script lang="ts" setup>
  defineProps<{
    foo: string;
    bar: string;
  }>();
</script>

<!-- comp.vue -->
<script lang="ts" setup>
  import Basic from "./basic.vue";
</script>

<template>
  <Basic />
</template>

When the fallthroughAttributes option is enabled on Comp, Comp inherits all props from Basic, allowing us to get prop completions for Basic when using Comp.

By default, however, the props inherited from Basic are all optional. This means we cannot enforce passing those required props when using Comp. At the same time, even if the required props from Basic are passed to Comp, Basic will still report missing prop errors.

After enabling the new checkRequiredFallthroughAttributes option on Comp, Comp will inherit Basic's props exactly as they are, and the missing prop errors on Basic inside Comp will disappear. This is because doing so is equivalent to promising that these required props should be passed when using Comp. Additionally, if some of the props required by Basic have already been passed directly to Basic, those props will be excluded from the inherited props.

(PR: #6049)

Bug Fixes

In subprojects using project references, importing Vue files from another project will no longer trigger TS6307 errors (PR: #6048)
When the js/ts.tsserver.experimental.enableProjectDiagnostics option is enabled, Vue files in large projects will no longer trigger diagnostics in an infinite loop (PR: #6051)

Deprecation Notice: Dropping Vue 2 and vue-class-component Support in v3.1: #5455

[!TIP]
Language Server Upgrade guide for non-vscode editors: #5456

Stability Improvements

Hybrid Mode Always On: Now always enabled to make the system simpler and more reliable. (PR: #5248)
Better Connection: Improved how Vue talks to TypeScript server, making it more stable. (PR: #5252, #5395, #5443)
Version Matching: Vue language server now requires specific Volar versions to work the same in all editors. (PR: #5345)
Fixed Startup Issue: Solved problems when both TypeScript and Vue extensions start together. (PR: #5260)

UX & DX Improvements

Navigation & Tooling

Global components now jump to their source files rather than type definitions. (PR: #5221)
Added support for TypeScript's sortImports and removeUnusedImports commands. (PR: #5444)
Implemented template refs document linking. (PR: #5385)

Localization Support

VSCode extension added multilingual support for:
- Chinese (Simplified/Traditional)
- Russian
- Japanese

(PR: #5330, #5340, #5404)

Streamlined UI

v3 does not have any status bar items

Compiler Options Updates

New TSConfig options:

strictSlotChildren: Strict type constraints of slot children. (PR: #5137)
strictVModel: Strict type constraints of v-model. (PR: #5229)
strictCssModules: Strict type checking of CSS modules. (PR: #5164)
resolveStyleImports: Specifies whether to generate type imports for external CSS files by <style src=\"...\"> or @import \"...\". (PR: #5136)

Renamed Settings

Some settings have new names:

vue.complete.casing.props → vue.suggest.propNameCasing
vue.complete.casing.tags → vue.suggest.componentNameCasing
vue.complete.defineAssignment → vue.suggest.defineAssignment
