Unlock Free Vue 3.0.7 Features: Template Highlight, Focus Mode, Reactivity Visualization

If you develop Vue projects, you probably use the official Vue extension (formerly Volar) in VS Code.

Version 3.0.7 introduces three previously paid features that are now free for everyone.

Template Interpolation Highlight

Complex Vue templates often contain many {{ ... }} interpolations that can be hard to read. This feature automatically highlights the expressions inside {{ ... }} with a distinct background or color, making variables stand out from static text. You can disable it in VS Code settings if the visual effect is too bright.

{
  "vue.editor.templateInterpolationDecorators": false
}

Focus Mode

When editing a Vue single‑file component, you normally switch between <template>, <script>, and <style>. Focus mode dims the non‑active sections, helping you concentrate on the part you are editing. In 3.0.7 the mode is disabled by default; you can enable it manually.

{
  "vue.editor.focusMode": true
}

Reactivity Visualization

Vue’s reactivity system can involve ref, reactive, computed, and watch dependencies that become tangled. Reactivity visualization marks data dependencies directly in the editor, so you can see which values depend on which sources.

{
  "vue.editor.reactivityVisualization": true
}

How to Use

Open VS Code and update the Vue extension to version 3.0.7 or later.

Edit .vscode/settings.json and set the desired flags: vue.editor.templateInterpolationDecorators → enable interpolation highlight. vue.editor.focusMode → enable focus mode. vue.editor.reactivityVisualization → enable reactivity visualization.

No sponsorship verification is required; the features work immediately after the update.

These three free features can significantly improve productivity for developers who spend a lot of time in Vue projects.

Strongly recommend upgrading the extension to experience them.
