Nova Storage Info Card Laravel Package

Technical Evaluation

Architecture fit. This is a presentation-layer widget for Laravel Nova — a dashboard/resource card that surfaces S3-type disk usage inside the admin panel. It is not a filesystem abstraction, storage driver, or capacity-management service. Its architectural footprint is intentionally minimal: one Nova Card class plus a compiled Vue component, registered from NovaServiceProvider::cards(). It adds no domain logic, no middleware, no persistence. Fit is therefore binary and narrow: valuable only in an estate that already runs Nova as its admin surface; zero value anywhere else, with no plausible path to reuse outside Nova.

Integration feasibility. High where preconditions hold, near-zero where they don't. Preconditions are (1) a paid Nova license and a supported Nova major, (2) an S3-type disk already declared in config/filesystems.php, and (3) working AWS credentials for that disk. Registration is a one-liner and config is publishable. There are no migrations, no service-provider bootstrapping beyond the card registration, and no changes to application runtime code.

Technical risk.

• Data-source ambiguity is the dominant risk. S3 exposes no cheap authoritative "bucket size" call. Implementations either enumerate objects via ListObjectsV2 — cost and latency scale linearly with object count, and pagination over large buckets can take minutes — or read CloudWatch BucketSizeBytes, which lags by up to ~24 hours and requires cloudwatch:GetMetricStatistics in the correct region. Which one this package uses determines whether it is a harmless tile or a dashboard-slowing, billable operation.
• Credential and permission surface. Either mode requires read permissions the application may not currently hold (bucket listing and/or CloudWatch metrics). This warrants an explicit least-privilege review rather than inheriting the disk's existing policy.
• Nova version lock. Nova cards depend on Nova's internal Vue component API, which has changed across Nova 3 → 4 → 5. The supplied metadata contains no compatibility matrix; assume tight coupling to whatever major was current at the author's last commit.
• Validation signal is effectively absent. Zero stars, zero dependents, score 0. Treat this as a readable code sample rather than a supported dependency. The realistic comparison is not "adopt vs. build from scratch" but "review ~200 lines vs. build ~200 lines" — a Nova card of this type is a small, well-understood piece of work, which caps the value of taking on an unvetted package.
• Supply chain. Small single-vendor Composer package; pin the version, read the source before install, and commit the lockfile.

Key questions.

1. Which Nova majors are supported, and what is the last commit date?
2. Does it compute size by enumerating objects or by reading CloudWatch? Is there caching or a TTL?
3. What is the exact IAM action set required, and is it documented?
4. Does it degrade gracefully on permission errors, or does an exception take down the Nova dashboard?
5. Does it support multiple disks, multiple regions, and multiple accounts?
6. What license, and is the author reachable for issues?

Integration Approach

Stack fit. Laravel + Nova + S3. Purely additive: no schema changes, no data migrations, no coupling into application services. Blast radius on failure is confined to one card's render, which is the strongest argument in its favor — the cost of being wrong is a broken tile, not a broken application.

Migration path. There is nothing to migrate from. If it replaces a manual console check or ad-hoc aws s3 ls --summarize, treat it as a convenience overlay, not a replacement: retain CloudWatch alarms and capacity alerting as the operational source
