@vue/shared

What is @vue/shared?

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.

What are @vue/shared's main functionalities?

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)); // false

Object 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'
