@vue/shared
Advanced tools
Package description
The @vue/shared package is a collection of utility functions used by Vue.js itself and can be leveraged in Vue.js projects or any other project where these utilities might be useful. It includes functions for object manipulation, type checking, and more, aiming to provide a lightweight and efficient set of tools for common programming tasks.
Type Checking
Provides functions to check the type of a variable, such as whether it is an object, string, function, etc. This is useful for ensuring that variables match expected types before performing operations on them.
import { isObject } from '@vue/shared';
console.log(isObject({})); // true
console.log(isObject(null)); // falseObject Manipulation
Includes functions to manipulate objects, such as extending one object with properties from another. This is useful for merging objects or copying properties.
import { extend } from '@vue/shared';
const obj1 = { a: 1 };
const obj2 = { b: 2 };
extend(obj1, obj2);
console.log(obj1); // { a: 1, b: 2 }String Capitalization
Provides simple string manipulation functions like capitalizing the first letter of a string. Useful for formatting text.
import { capitalize } from '@vue/shared';
console.log(capitalize('hello')); // 'Hello'Lodash is a comprehensive utility library offering a wide range of functions for tasks including object manipulation, array manipulation, string manipulation, and more. It's more extensive than @vue/shared but also larger in size, making it more suitable for projects where a wide variety of utility functions are needed.
Ramda is a functional programming utility library focused on simplicity and immutability. While it shares some functionality with @vue/shared, such as object manipulation, Ramda emphasizes a functional programming approach, offering tools for creating pipelines and composing functions.

3.4.1 (2023-12-30)
Read this blog post for an overview of the release highlights.
To fully leverage new features in 3.4, it is recommended to also update the following dependencies when upgrading to 3.4:
If using TSX with Vue, check actions needed in Removed: Global JSX Namespace.
Make sure you are no longer using any deprecated features (if you are, you should have warnings in the console telling you so). They may have been removed in 3.4.

This is necessary to avoid global namespace collision with React so that TSX of both libs can co-exist in the same project. This should not affect SFC-only users with latest version of Volar.
If you are using TSX, there are two options:
Explicitly set jsxImportSource to 'vue' in tsconfig.json before upgrading to 3.4. You can also opt-in per file by adding a /* @jsxImportSource vue */ comment at the top of the file.
If you have code that depends on the presence of the global JSX namespace, e.g. usage of types like JSX.Element etc., you can retain the exact pre-3.4 global behavior by explicitly referencing vue/jsx, which registers the global JSX namespace.
Note that this is a type-only breaking change in a minor release, which adheres to our release policy.
app.config.unwrapInjectedRef has been removed. It was deprecated and enabled by default in 3.3. In 3.4 it is no longer possible to disable this behavior.@vnodeXXX event listeners in templates are now a compiler error instead of a deprecation warning. Use @vue:XXX listeners instead.v-is directive has been removed. It was deprecated in 3.3. Use the is attribute with vue: prefix instead.Readme
