# Sidebar Injection Architecture
## Overview
The soleprint sidebar is injected into managed app pages using a hybrid nginx + JavaScript approach. This allows any frontend framework (React, Next.js, static HTML) to receive the sidebar without code modifications.
## How It Works
```
┌─────────────────────────────────────────────────────────────────┐
│ Browser Request │
│ http://room.spr.local.ar/ │
└─────────────────────────────────────────────────────────────────┘
│
▼
┌─────────────────────────────────────────────────────────────────┐
│ Nginx │
│ │
│ 1. Routes /spr/* → soleprint:PORT (sidebar assets + API) │
│ 2. Routes /* → frontend:PORT (app pages) │
│ 3. Injects CSS+JS into HTML responses via sub_filter │
│ │
│ sub_filter '</head>' │
│ '<link rel="stylesheet" href="/spr/sidebar.css"> │
│ <script src="/spr/sidebar.js" defer></script></head>'; │
└─────────────────────────────────────────────────────────────────┘
│
▼
┌─────────────────────────────────────────────────────────────────┐
│ Browser Renders │
│ │
│ 1. Page loads with injected CSS (sidebar styles ready) │
│ 2. sidebar.js executes (deferred, after DOM ready) │
│ 3. JS fetches /spr/api/sidebar/config (room name, auth, etc) │
│ 4. JS creates sidebar DOM elements and injects into page │
│ 5. Sidebar appears on left side, pushes content with margin │
└─────────────────────────────────────────────────────────────────┘
```
## Key Design Decisions
### Why nginx sub_filter instead of modifying app code?
- **Framework agnostic**: Works with any frontend (Next.js, React, Vue, static HTML)
- **No app changes needed**: The managed app doesn't need to know about soleprint
- **Easy to disable**: Just access `room.local.ar` instead of `room.spr.local.ar`
### Why inject into `</head>` instead of `</body>`?
Next.js and other streaming SSR frameworks may not include `</body>` in the initial HTML response. The `</head>` tag is always present, so we inject both CSS and JS there using `defer` to ensure JS runs after DOM is ready.
### Why JavaScript injection instead of iframe?
- **No iframe isolation issues**: Sidebar can interact with page if needed
- **Better UX**: No double scrollbars, native feel
- **Simpler CSS**: Just push content with `margin-left`
## Nginx Configuration
### For Local Development (system nginx)
Each room needs entries in `/etc/nginx/sites-enabled/`:
```nginx
# room.spr.local.ar - app with sidebar
server {
listen 80;
server_name room.spr.local.ar;
# Soleprint assets and API
location /spr/ {
proxy_pass http://127.0.0.1:SOLEPRINT_PORT/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
# Backend API (if applicable)
location /api/ {
proxy_pass http://127.0.0.1:BACKEND_PORT/api/;
# ... headers
}
# Frontend with sidebar injection
location / {
proxy_pass http://127.0.0.1:FRONTEND_PORT;
proxy_set_header Host $host;
proxy_set_header Accept-Encoding ""; # Required for sub_filter
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
# Inject sidebar
sub_filter '</head>' '<link rel="stylesheet" href="/spr/sidebar.css"><script src="/spr/sidebar.js" defer></script></head>';
sub_filter_once off;
sub_filter_types text/html;
}
}
# room.local.ar - app without sidebar (direct access)
server {
listen 80;
server_name room.local.ar;
# ... same as above but without sub_filter
}
```
### For Docker/AWS (nginx container)
The nginx config lives in `cfg/<room>/soleprint/nginx/local.conf` and uses docker service names instead of localhost ports:
```nginx
location /spr/ {
proxy_pass http://soleprint:8000/spr/;
}
location / {
proxy_pass http://frontend:3000;
# ... sub_filter same as above
}
```
## Port Allocation
Each room should use unique ports to allow concurrent operation:
| Room | Soleprint | Frontend | Backend |
|--------|-----------|----------|---------|
| amar | 12000 | 3000 | 8001 |
| dlt | 12010 | 3010 | - |
| sample | 12020 | 3020 | 8020 |
## Sidebar Assets
The sidebar consists of two files served by soleprint:
- `/sidebar.css` - Styles for the sidebar (dark theme, positioning)
- `/sidebar.js` - Self-contained JS that fetches config and renders sidebar
Source location: `soleprint/station/tools/sbwrapper/`
## Sidebar Config API
The sidebar JS fetches configuration from `/spr/api/sidebar/config`:
```json
{
"room": "amar",
"soleprint_base": "/spr",
"auth_enabled": true,
"tools": {
"artery": "/spr/artery",
"atlas": "/spr/atlas",
"station": "/spr/station"
},
"auth": {
"login_url": "/spr/artery/google/oauth/login",
"logout_url": "/spr/artery/google/oauth/logout"
}
}
```
## Troubleshooting
### Sidebar not appearing
1. Check if soleprint is running: `curl http://room.spr.local.ar/spr/sidebar.js`
2. Check browser console for `[Soleprint]` messages
3. Verify nginx has `Accept-Encoding ""` set (required for sub_filter)
4. Hard refresh (Ctrl+Shift+R) to clear cached HTML
### Wrong room config showing
Each room needs its own docker network (`room_network`) to isolate services. Check `NETWORK_NAME` in `.env` files and ensure containers are on correct networks.
### sub_filter not working
- Ensure `proxy_set_header Accept-Encoding ""` is set
- Check that response is `text/html` (sub_filter_types)
- Streaming SSR may not have `</body>`, use `</head>` injection instead
