# AIUI nginx config for Archipelago deployment
# Include this in your Archy nginx server block.
#
# Prerequisites:
# - AIUI built and placed in /opt/archipelago/web-ui/aiui/
# - Set $anthropic_api_key in nginx or via env (see below)
#
# Usage in nginx.conf:
#   include /opt/archipelago/web-ui/aiui/nginx-archy.conf;

# Serve AIUI SPA
location /aiui/ {
    alias /opt/archipelago/web-ui/aiui/;
    try_files $uri $uri/ /aiui/index.html;

    # Cache static assets aggressively
    location ~* /aiui/assets/ {
        expires 1y;
        add_header Cache-Control "public, immutable";
    }
}

# Proxy Claude API requests from AIUI iframe
# AIUI fetches /api/claude/v1/messages → proxied to Anthropic API
location /aiui/api/claude/ {
    # Rewrite: strip /aiui/api/claude prefix, forward to Anthropic
    rewrite ^/aiui/api/claude/(.*)$ /$1 break;

    proxy_pass https://api.anthropic.com;
    proxy_ssl_server_name on;
    proxy_set_header Host api.anthropic.com;
    proxy_set_header x-api-key $anthropic_api_key;
    proxy_set_header anthropic-version "2023-06-01";
    proxy_set_header Content-Type "application/json";

    # SSE streaming support
    proxy_buffering off;
    proxy_cache off;
    proxy_read_timeout 300s;
    proxy_http_version 1.1;
    proxy_set_header Connection "";

    # Security: only allow from same origin (AIUI iframe)
    # The iframe has sandbox="allow-same-origin" so requests come from Archy's origin
}

# Proxy OpenRouter API requests (optional, for multi-model support)
location /aiui/api/openrouter/ {
    rewrite ^/aiui/api/openrouter/(.*)$ /api/v1/chat/completions break;

    proxy_pass https://openrouter.ai;
    proxy_ssl_server_name on;
    proxy_set_header Host openrouter.ai;
    proxy_set_header Content-Type "application/json";

    proxy_buffering off;
    proxy_cache off;
    proxy_read_timeout 300s;
    proxy_http_version 1.1;
