Overview
Capacity, persistence, scope, and structure
| Type | Capacity | Persistence | Scope | Structure |
|---|
Notes:
- Capacities are “typical” and vary by browser/device, storage pressure, and user settings. For quota-managed storage, use navigator.storage.estimate().
- Scope is usually “per origin” (scheme + host + port). Cookies are special (domain/path rules) and are sent with requests.
- Cache API usually requires a secure context (HTTPS / localhost).
