When to Use LocalStorage vs IndexedDB
Updated
LocalStorage Can Break Your Page 🧑💻
LocalStorage has some limitations which may break your page if quotas are exceeded. 🤯
Therefore, I will compare it to an alternative called IndexedDB today. 💿
Storage Cap
LocalStorage is limited to ~5MB, great for small data. IndexedDB shines with much more space, perfect for complex data needs.
Data Format
Key-value pairs in LocalStorage (all strings) vs structured, object storage in IndexedDB - a win for complex queries!
Sync vs Async
LocalStorage runs sync, can slow things down. IndexedDB's async nature keeps things smooth and performant.
Transactions
No transactions in LocalStorage; each action stands alone. IndexedDB supports transactions, bundling multiple actions for data integrity.
Browser Support:
Both are widely supported, but IndexedDB might have slight variations across browsers. 🌎
Use Cases
LocalStorage? Think user prefs or small app states. IndexedDB? Ideal for offline storage, large datasets, and complex data management.
Security
Both adhere to same-origin policy, ensuring data is accessible only within its origin domain. 🔐
