-`set()`, `del()` and `nextTick()` are also provided as named exports in ESM builds.
- The `emits` option is also supported, but only for type-checking purposes (does not affect runtime behavior)
2.7 also supports using ESNext syntax in template expressions. When using a build system, the compiled template render function will go through the same loaders / plugins configured for normal JavaScript. This means if you have configured Babel for `.js` files, it will also apply to the expressions in your SFC templates.
### Notes on API exposure
- In ESM builds, these APIs are provided as named exports (and named exports only):
```js
import Vue, { ref } from 'vue'
Vue.ref // undefined, use named export instead
```
- In UMD and CJS builds, these APIs are exposed as properties on the global `Vue` object.
- When bundling with CJS builds externalized, bundlers should be able to handle ESM interop when externalizing CJS builds.
### Behavior Differences from Vue 3
The Composition API is backported using Vue 2's getter/setter-based reactivity system to ensure browser compatibility. This means there are some important behavior differences from Vue 3's proxy-based system:
- All [Vue 2 change detection caveats](https://v2.vuejs.org/v2/guide/reactivity.html#Change-Detection-Caveats) still apply.
-`reactive()`, `ref()`, and `shallowReactive()` will directly convert original objects instead of creating proxies. This means:
```js
// true in 2.7, false in 3.x
reactive(foo) === foo
```
-`readonly()`**does** create a separate object, but it won't track newly added properties and does not work on arrays.
- Avoid using arrays as root values in `reactive()` because without property access the array's mutation won't be tracked (this will result in a warning).
- Reactivity APIs ignore properties with symbol keys.
In addition, the following features are explicitly **NOT** ported:
- ❌ `createApp()` (Vue 2 doesn't have isolated app scope)
- ❌ Top-level `await` in `<script setup>` (Vue 2 does not support async component initialization)
-`defineComponent` provides improved type inference similar to that of Vue 3. Note the type of `this` inside `defineComponent()` is not interoperable with `this` from `Vue.extend()`.
- Similar to Vue 3, TSX support is now built-in. If your project previously had manual JSX type shims, make sure to remove them.
1. Upgrade local `@vue/cli-xxx` dependencies the latest version in your major version range (if applicable):
-`~4.5.18` for v4
-`~5.0.6` for v5
2. Upgrade `vue` to `^2.7.0`. You can also remove `vue-template-compiler` from the dependencies - it is no longer needed in 2.7.
Note: if you are using `@vue/test-utils`, you may need to keep it in the dependencies for now, but this requirement will also be lifted in a new release of test utils.
3. Check your package manager lockfile to ensure the following dependencies meet the version requirements. They may be transitive dependencies not listed in `package.json`.
-`vue-loader`: `^15.10.0`
-`vue-demi`: `^0.13.1`
If not, you will need to remove `node_modules` and the lockfile and perform a fresh install to ensure they are bumped to the latest version.
4. If you were previously using [`@vue/composition-api`](https://github.com/vuejs/composition-api), update imports from it to `vue` instead. Note that some APIs exported by the plugin, e.g. `createApp`, are not ported in 2.7.
5. Update `eslint-plugin-vue` to latest version (9+) if you run into unused variable lint errors when using `<script setup>`.
6. The SFC compiler for 2.7 now uses PostCSS 8 (upgraded from 7). PostCSS 8 should be backwards compatible with most plugins, but the upgrade **may** cause issues if you were previously using a custom PostCSS plugin that can only work with PostCSS 7. In such cases, you will need to upgrade the relevant plugins to their PostCSS 8 compatible versions.
### Vite
2.7 support for Vite is provided via a new plugin: [@vitejs/plugin-vue2](https://github.com/vitejs/vite-plugin-vue2). This new plugin requires Vue 2.7 or above and supersedes the existing [vite-plugin-vue2](https://github.com/underfin/vite-plugin-vue2).
Note that the new plugin does not handle Vue-specific JSX / TSX transform, which is intentional. Vue 2 JSX / TSX transform should be handled in a separate, dedicated plugin, which will be provided soon.
### Volar Compatibility
2.7 ships improved type definitions so it is no longer necessary to install `@vue/runtime-dom` just for Volar template type inference support. All you need now is the following config in `tsconfig.json`:
```json
{
// ...
"vueCompilerOptions": {
"target": 2.7
}
}
```
### Devtools Support
Vue Devtools 6.2.0 has added support for inspecting 2.7 Composition API state, but the extensions may still need a few days to go through review on respective publishing platforms.

- The reactivity system is still getter/setter based and does not use Proxies, so all Vue 2 change detection caveats still apply.
-`reactive()`, `ref()`, and `shallowReactive()` will directly convert original objects instead of creating proxies. They also do not convert properties with symbol keys.
- Avoid using arrays as root values in `reactive()` because without property access the array's mutation won't be tracked (this will result in a warning).
-`readonly()`**does** create a separate object, but it won't track newly added properties and does not work on arrays.
