Test it
Using "delon-cache-caching-strategies". A task list service repeatedly loads the same data for one page.
Expected outcome:
- A memory cache is recommended for short-lived task data.
- The cache key should include the task list scope.
- The entry should expire after five minutes.
- Create and update operations should remove related list keys.
Using "delon-cache-caching-strategies". A user preferences service needs values to survive page reloads.
Expected outcome:
- LocalStorage is appropriate for non-sensitive preferences.
- A longer TTL can be used for display settings.
- The design should exclude tokens, secrets, and private records.
Using "delon-cache-caching-strategies". An Angular app wants to cache GET responses globally.
Expected outcome:
- Only cache safe, idempotent responses.
- Skip realtime, authenticated, and user-specific endpoints unless keys include identity context.
- Provide a header or route rule to bypass cache when needed.
Security Audit
Medium Riskv6 • 7/4/2026 Open versioned report
All static command-execution, reconnaissance, and direct network findings were adjudicated as false positives caused by Markdown, TypeScript examples, or documentation links. No prompt injection, malicious execution, or data exfiltration intent was found. Semantic review found one medium cache isolation risk in the HTTP interceptor guidance.

Unscoped HTTP Response Cache Could Expose User Data
The interceptor caches every GET response by URL unless a skip header or realtime path is present. Authenticated or user-specific responses could be reused after an account change because the key does not include user or tenant context.
The code sample clearly caches GET responses using only req.urlWithParams and provides only narrow bypass logic. The impact depends on how adopters apply the interceptor, so confidence is high enough to flag but not critical.

What You Can Build
Add client-side cache wrappers
Create an Angular service that wraps @delon/cache with consistent keys, TTLs, and storage choices.
Reduce repeated API requests
Apply memory caching or HTTP interception to frequently requested data with short expiration windows.
Standardize cache invalidation
Document when cache entries must be removed after create, update, or grouped data changes.
Try These Prompts
Add Basic Memory Cache
Add a memory cache to this Angular service using @delon/cache. Use a five minute TTL and keep invalidation simple.
Choose Browser Storage
Review this Angular preference service and choose memory, LocalStorage, or SessionStorage. Explain the TTL and sensitive data risks.
Design Cache Invalidation
Design a cache invalidation plan for these create and update flows. Include keys, groups, TTLs, and missed invalidation risks.
Audit HTTP Cache Interceptor
Audit this Angular HTTP cache interceptor. Identify stale data, authentication, tenant isolation, and cache bypass requirements.
Best Practices
- Use memory cache for short-lived API data unless persistence is required.
- Set TTL values based on data volatility and user impact.
- Invalidate related keys after writes, not only the item key.
Avoid
- Do not store auth tokens, secrets, or sensitive personal data in browser storage.
- Do not cache responses that include user-specific data under shared keys.
- Do not omit invalidation for data that users can edit.
Frequently Asked Questions
What does this skill help build?
It helps build Angular caching patterns with @delon/cache, including TTLs, storage selection, and invalidation.
Does it support persistent browser storage?
Yes. It includes LocalStorage and SessionStorage examples for data that is safe to store in the browser.
Can it cache HTTP requests?
Yes. It shows an Angular interceptor pattern for caching selected GET responses.
Does it replace server-side caching?
No. It focuses on client-side Angular caching and does not cover Redis or distributed cache systems.
Is it safe for sensitive data?
Use caution. Do not place credentials, tokens, secrets, or regulated personal data in browser storage.
Which AI coding tools can use it?
The skill is intended for Claude, Codex, and Claude Code workflows.
