getCache(key) Method in Merciglobal Cloud ERP¶

The getCache(key) method is a utility function used to retrieve previously stored values from the server-side or client-side cache in Merciglobal Cloud ERP. Caching is a crucial performance enhancement strategy used across various modules of the ERP system.

Overview¶

getCache(key) is primarily used for:

Boosting performance by reducing repeated data fetches
📉 Minimizing API/database calls
💾 Reusing frequently accessed data

Syntax¶

getCache(key: string): any

key: A string identifier representing the cached object.
Returns: The cached value associated with the key, or null if not found.

Use Cases in Merciglobal Cloud ERP¶

🔄 Fetching frequently accessed configuration values
📊 Retrieving dashboard analytics data
📁 Loading master data like currency, country codes, tax rates, etc.

Example¶

const userSettings = getCache('user_settings');

if (userSettings) {
  console.log('User settings loaded from cache:', userSettings);
} else {
  console.log('No cached data found, fetch from server.');
}

Where is Caching Implemented?¶

In Merciglobal Cloud ERP, caching is intelligently implemented across:

🧩 UI Components (e.g., for filters, options)
🔐 User sessions
🌐 HTTP service wrappers

Cache Expiry & Invalidation¶

Caching in Merciglobal includes TTL (Time to Live) and manual invalidation methods:

clearCache(key) – to manually remove a specific cache key
Automatic TTL expiry set during setCache(key, value, ttl) usage

Best Practices¶

Always check the cache before API calls to reduce latency
Use unique and consistent keys to avoid conflicts
Avoid caching sensitive or frequently changing data

Method	Description
`setCache(key, value, ttl)`	Stores data in cache with an optional expiration time
`clearCache(key)`	Clears the specific cached key
`hasCache(key)`	Checks if a key exists in cache

Security Notes¶

Cached data is accessible only within the user's session scope unless globally stored.
Never cache passwords, tokens, or PII data.
