Verdict

“The core issue is hostname mismatch, and the industry standard is to generate presigned URLs with a public‑reachable endpoint, not to proxy through a backend.”

The problem you are solving - presigned URLs that embed an internal hostname that browsers cannot resolve - is a well‑known limitation of S3‑compatible storage when the client and the URL‑generation service run on different network namespaces. Production systems typically avoid a server‑side proxy and instead generate URLs that point to a hostname reachable from the client. This is done by (1) configuring the SDK or presigner with a separate public endpoint (e.g., STORAGE_PUBLIC_ENDPOINT) while keeping the internal MinIO address for the client, or (2) exposing MinIO through a reverse‑proxy/Nginx that presents a consistent DNS name both inside and outside the cluster. Both patterns are documented by MinIO, AWS S3, and most cloud‑native storage operators, and they are supported out‑of‑the‑box by Kubernetes Ingress, Cloudflare, or dedicated load balancers. Your current proxy approach works but adds latency, extra surface area, and operational complexity, making it an anti‑pattern rather than a best practice. Because the solution you propose is essentially a re‑implementation of an established pattern, there is little defensible differentiation; a new entrant would need to add unique value such as automated DNS‑based endpoint selection, per‑tenant public host provisioning, or a SaaS layer that abstracts the whole process. Without such added differentiation, the idea is unlikely to sustain a competitive moat.

“Generating presigned URLs with a public endpoint from the start is the most efficient and scalable solution.”

The current proxy approach is functional but introduces unnecessary complexity and potential latency. The best option is to configure the backend with a separate `STORAGE_PUBLIC_ENDPOINT` so presigned URLs are generated with a browser-reachable hostname. This avoids the need for a proxy and simplifies the architecture. Using a reverse proxy like Nginx is also viable but adds operational overhead. Most production setups prefer the first option for its simplicity and directness. The key insight is that generating presigned URLs with a public endpoint from the start is the most efficient and scalable solution.

“The proxy is a technical debt trap that will fail under regulatory scrutiny or budget constraints within 6 months.”

The server-side proxy approach creates a fragile dependency on Nuxt's routing layer, which is prone to breaking with framework updates or traffic spikes. If the proxy fails, all file access halts, directly impacting revenue. Regulatory risks arise if internal URLs leak data metadata (e.g., filenames revealing sensitive info), violating GDPR/HIPAA. No-budget customers will churn if the proxy requires maintenance costs they can't afford. A reverse proxy (Nginx) shifts risk but requires expertise; without it, the proxy becomes a single point of failure. Production setups typically use S3's public endpoint directly or API gateways with proper CORS, avoiding internal hostnames entirely.
