What is Global State?

Global state refers to data that is shared across multiple components in a Vue application.

Why Use Global State?

Share data across components
Avoid prop drilling
Maintain consistent data
Simplify data flow in large apps

Using Reactive Object

JavaScriptRead-only

import { reactive } from 'vue';

export const store = reactive({
  count: 0
});

import { reactive } from 'vue';

export const store = reactive({
  count: 0
});

Using Global State in Component

JavaScriptRead-only

import { store } from './store';

store.count++;
console.log(store.count);

import { store } from './store';

store.count++;
console.log(store.count);

Provide & Inject

JavaScriptRead-only

provide('message', 'Hello');

inject('message');

provide('message', 'Hello');

inject('message');

Using Pinia (Recommended)

For scalable applications, use Pinia for managing global state efficiently.

When to Use

Multiple components need same data
Large applications
Complex state logic
User authentication data

Best Practices

Use global state only when necessary
Keep state centralized
Use Pinia for scalability
Avoid overcomplicating simple apps

Common Mistakes

Overusing global state
Not organizing state properly
Mixing multiple state patterns
Ignoring reactivity rules

Conclusion

Global state helps manage shared data efficiently in Vue applications, but should be used wisely to maintain clean architecture.
