feat: make demo mode data more realistic by fergusfinn · Pull Request #731 · doublewordai/control-layer

fergusfinn · 2026-02-18T16:46:19Z

Summary

Expand all mock data to be more 'prod-like'
Add model tariff/pricing data for all commercial models with standard + batch tiers
Dynamic time-shifting for request timestamps so the demo never expires
Fix request viewer (was empty due to handler returning wrong response shape) and analytics (white screen crash due to type mismatches in aggregate response)
Add React ErrorBoundary to App.tsx for better error visibility in demo mode

Test plan

Load demo mode at / — verify dashboard renders without white screen
Navigate to Analytics → Dashboard tab — verify charts and metrics display correctly (no NaN values)
Navigate to Analytics → Requests tab — verify request table is populated with entries showing model, status, duration, tokens, and cost columns
Filter requests by model using the dropdown — verify server-side filtering works
Check Models page — verify 12 models listed with pricing when expanded
Check Users page — verify 15 users with correct group memberships
Check Cost Management — verify transactions and balances display correctly

Expand mock data to closely mirror the production deployment: - Users: 6 → 15, with proxy-header auth format (github|<id>) - Groups: 5 → 8 (Engineering, Research, Support, etc.) - Models: 5 → 12 (Claude, GPT-4o, DeepSeek, Gemini, Llama, Qwen, embeddings, reranker) - Endpoints: 4 → 6 (Anthropic, OpenAI, self-hosted, embedding providers) - Transactions: 8 → 24, with realistic amounts and descriptions - API keys: 2 → 5 (CI/CD, batch processing, partner, dev, monitoring) - Requests: 10 → 500, with realistic token counts and latencies - Batches: updated model names to match new model aliases Key improvements: - Add model tariff/pricing data for all commercial models - Dynamic time-shifting so request timestamps never expire - Fix /admin/api/v1/requests handler to return AnalyticsEntry[] format (was returning raw DemoRequest objects under wrong key, causing empty request viewer) - Fix /admin/api/v1/requests/aggregate handler response types to match StatusCodeBreakdown[], ModelUsage[], TimeSeriesPoint[] (was returning wrong shapes, causing white screen crash) - Add React ErrorBoundary to App.tsx for better error visibility - Default demo user (Sarah Chen) has all roles for full UI exploration

Pull request overview

This PR significantly expands the demo mode mock data to better represent a production deployment. The changes make the demo data more realistic and fix critical bugs that were preventing the request viewer and analytics dashboard from working correctly.

Changes:

Expanded mock data across all entities: users (6→15), groups (5→8), models (5→12), endpoints (4→6), API keys (2→5), and transactions (8→24)
Added comprehensive model tariff/pricing data with standard and batch tiers for all commercial models
Implemented dynamic time-shifting for request timestamps to keep demo data perpetually current
Fixed request viewer by returning correct ListAnalyticsResponse shape with entries array
Fixed analytics aggregate response to match RequestsAggregateResponse interface with proper ModelUsage and TimeSeriesPoint types
Added React ErrorBoundary to App.tsx for better error visibility and recovery in demo mode
