🔴 Critical: Unmet peer dependency — [email protected] incompatible with vite 5

[email protected] declares a peer constraint of vite ^2 || ^3 || ^4. Upgrading vite to ^5.4.21 (line 18) while keeping [email protected] (line 19) causes npm install to fail with an ERESOLVE error, breaking the dev server and build for this example.

This example is on Vue 2.6, which is incompatible with the maintained @vitejs/plugin-vue2. Choose one fix:

  • Revert vite to ^4.x if this example should remain on Vue 2.6
  • Upgrade to Vue 2.7, migrate to @vitejs/plugin-vue2, and optionally upgrade vite to ^7.2.2 per the PR objective

Option 1: Keep Vue 2.6 — revert vite to compatible version

  "devDependencies": {
    "typescript": "5.8.3",
-   "vite": "^5.4.21",
+   "vite": "^4.5.14",
    "vite-plugin-vue2": "2.0.3"
  }

Option 2: Migrate to Vue 2.7 and @vitejs/plugin-vue2 (aligns with PR objective of vite 7)

  "dependencies": {
    "@tanstack/vue-query": "^5.90.2",
    "@vue/composition-api": "1.7.2",
-   "vue": "2.6.14",
-   "vue-template-compiler": "2.6.14"
+   "vue": "2.7.16",
+   "vue-template-compiler": "2.7.16"
  },
  "devDependencies": {
    "typescript": "5.8.3",
-   "vite": "^5.4.21",
-   "vite-plugin-vue2": "2.0.3"
+   "vite": "^7.2.2",
+   "@vitejs/plugin-vue2": "^2.4.0"
  }

Then update vite.config.js to import and use @vitejs/plugin-vue2 instead of vite-plugin-vue2.

Please clarify whether this example should remain on Vue 2.6 or migrate to 2.7 to align with the PR security update goal.

🌐 Web query:

vite-plugin-vue2 2.0.3 peer dependencies vite

💡 Result:

[email protected] declares a peerDependency on vite >= 2.0.0. [1][2]

Sources:

  • Libraries.io package page for vite-plugin-vue2. [1]
  • Socket / npm package metadata listing (vite peer requirement). [2]

🌐 Web query:

@vitejs/plugin-vue2 vite 7 compatibility

💡 Result:

Short answer: Likely yes — @vitejs/plugin-vue2 works with Vue 2.7 and is listed as an official Vite plugin, and there’s no public documentation saying it’s incompatible with Vite 7. However the plugin targets Vue 2.7 and is no longer actively maintained, so you may hit peer-dependency or plugin-API breakages when upgrading to Vite 7; other official/community plugins have already needed updates for Vite 7. Test in a branch and pin versions (or use a patched fork) if you hit issues. [1][2][3][4]

Sources

  • @vitejs/plugin-vue2 (README / npm / GitHub): plugin for Vue 2.7 (official plugin, not actively maintained). [1][2]
  • Vite breaking-changes / plugins notes (Vite 7 introduced API/peer changes; other plugins needed updates — e.g. Tailwind plugin peer-dep issue). [3][4]

If you want I can:

  • check the plugin’s package.json for any strict vite peerDependency, or
  • run a quick compatibility checklist (common failure points) against Vite 7 for you.

🔴 Critical: Vite-plugin-vue2 incompatible with vite 5 — version error in Option 2, and vite.config.js must be created

[email protected] declares peer constraint "vite": "^2.0.0 || ^3.0.0 || ^4.0.0". Upgrading vite to ^5.4.21 (line 18) while keeping [email protected] (line 19) causes npm install to fail with an ERESOLVE error, breaking this example's dev server and build.

Two valid paths exist:

Option 1: Keep Vue 2.6 — revert vite to ^4.x

  "devDependencies": {
    "typescript": "5.8.3",
-   "vite": "^5.4.21",
+   "vite": "^4.5.14",
    "vite-plugin-vue2": "2.0.3"
  }

Option 2: Migrate to Vue 2.7 and @vitejs/plugin-vue2

@vitejs/plugin-vue2 latest (2.3.4) supports "vite": "^3.0.0 || ^4.0.0 || ^5.0.0 || ^6.0.0 || ^7.0.0", and @tanstack/[email protected] supports "vue": "^2.6.0", making Vue 2.7.16 compatible.

Update package.json:

  "dependencies": {
    "@tanstack/vue-query": "^5.90.2",
    "@vue/composition-api": "1.7.2",
-   "vue": "2.6.14",
-   "vue-template-compiler": "2.6.14"
+   "vue": "2.7.16",
+   "vue-template-compiler": "2.7.16"
  },
  "devDependencies": {
    "typescript": "5.8.3",
-   "vite": "^5.4.21",
-   "vite-plugin-vue2": "2.0.3"
+   "vite": "^7.2.2",
+   "@vitejs/plugin-vue2": "^2.3.4"
  }

Create vite.config.js (file does not currently exist):

import { defineConfig } from 'vite'
import createVuePlugin from '@vitejs/plugin-vue2'

export default defineConfig({
  plugins: [createVuePlugin()]
})

Clarify whether this example should remain on Vue 2.6 (requiring Option 1) or migrate to 2.7 (Option 2).
