Enhancement - Add Corporate Proxy Support

[Mrassimo]

Description

Corporate environments often require proxy configuration for internet access. DataPilot should support standard proxy protocols for enterprise deployment.

Current State

• Package.json includes "proxy-friendly" keyword
• No explicit proxy configuration options
• May fail in corporate environments with mandatory proxies

Proposed Features

Command Line Options

datapilot --proxy http://proxy.company.com:8080 all data.csv
datapilot --proxy-auth user:password all data.csv
datapilot --no-proxy all data.csv  # Bypass proxy detection

Environment Variable Support

export HTTP_PROXY=http://proxy.company.com:8080
export HTTPS_PROXY=http://proxy.company.com:8080  
export NO_PROXY=localhost,127.0.0.1
datapilot all data.csv

Configuration File Support

# .datapilotrc
proxy:
  http: "http://proxy.company.com:8080"
  https: "http://proxy.company.com:8080"
  auth: "user:password"
  bypass: ["localhost", "*.internal.com"]

Enterprise Requirements

• NTLM/Kerberos authentication support
• Proxy auto-detection
• SSL certificate validation options
• Timeout configuration

Implementation Notes

Since DataPilot processes files locally and doesn't make external HTTP requests, this may primarily be needed for:

• Future features that fetch external data
• Package installation/updates
• Telemetry (if added)

Priority

Medium - Required for some enterprise deployments where proxy is mandatory

Status: Valid future enhancement, but not currently needed

After analysis, DataPilot currently operates as a local-only file analysis tool that doesn't make external HTTP requests. The tool processes files entirely on the local machine without network dependencies.

Current network usage: None

• No external API calls
• No telemetry or usage reporting
• No remote data fetching
• Processes files locally using streaming algorithms

When proxy support would be needed:

• Future features that fetch external reference data
• If telemetry/analytics are added
• Integration with cloud data sources
• Package installation (handled by npm/yarn, not DataPilot itself)

Recommendation:
Keep this open as a future enhancement for when network features are added, but it's not blocking current enterprise deployment since the tool works entirely offline.

Current enterprise deployment options:

• Standalone executables (no network needed) - Issue Enhancement - Add Standalone Executables for Enterprise Deployment #38 ✅
• Offline package installation - Available now
• Air-gapped environments - Fully supported

Proxy support can be implemented when/if network features are added to the roadmap.
