fix: require() to dynamic import() in ESM + event subscriptions
routes-os-updates.ts used require() which fails in ESM. Changed to dynamic import(). Also includes persistent event topic subscriptions with status tracking (inactive/pending/active/failed), merge-only refresh, and colored status dots in camera detail UI.

# BSB Framework — Practical Learnings
|
||||
|
||||
Lessons learned building BetterFrame on BSB v9. Intended for updating
|
||||
bsbcode.dev/llms.txt so future LLM sessions don't repeat these mistakes.
|
||||

|
||||
## Container Runtime
|
||||
|
||||
### Base Image
|
||||
- Image: `betterweb/service-base:9` (Docker Hub)
|
||||
- Alpine-based (use `apk` not `apt-get`)
|
||||
- Entrypoint: `/root/entrypoint.sh` — runs as root, drops to unprivileged user
|
||||
- **DO NOT** set `USER` in child Dockerfiles — BSB entrypoint handles privilege dropping
|
||||
- **DO NOT** override `CMD` or `ENTRYPOINT` — BSB handles startup
|
||||
|
||||
### Production Environment
|
||||
- Set `ENV NODE_ENV=production` and `ENV BSB_LIVE=true` in Dockerfile
|
||||
- Without `BSB_LIVE=true`, BSB warns about non-production and tries to write sec-config.yaml
|
||||
|
||||
### Plugin Discovery
|
||||
- BSB searches: `/home/bsb/node_modules/<package>/lib/plugins/<type>-<name>/index.js`
|
||||
- Also searches: `/mnt/bsb-plugins/node_modules/...` but this is a VOLUME — build-time COPY gets shadowed by empty anonymous volume at runtime
|
||||
- **USE `/home/bsb/node_modules/`** for build-time plugin installation
|
||||
- Working directory is `/home/bsb`
|
||||
|
||||
### Plugin Registration in Config
|
||||
```yaml
|
||||
services:
|
||||
service-my-plugin:
|
||||
package: my-npm-package-name # <-- REQUIRED for container mode
|
||||
plugin: service-my-plugin
|
||||
enabled: true
|
||||
config: {}
|
||||
```
|
||||
Without `package:`, BSB only finds built-in plugins (config-default, events-default, log-default).
|
||||
|
||||
The `package` value must match the `name` field in the plugin's `package.json`.
|
||||
|
||||

|
||||
|
||||
## Config Schema
|
||||
|
||||
### Schema Extractor Limitations
|
||||
- `bsb-plugin-cli build` extracts config schemas from TypeScript source **statically**
|
||||
- **Cannot resolve cross-file imports** — imported schema variables show as "not defined"
|
||||
- Workaround: inline anyvali schema definitions in each plugin's ConfigSchema
|
||||
- Type-only imports (`import type { ... }`) are fine — only runtime value imports break extraction
|
||||
|
||||
```typescript
|
||||
// BAD — schema extractor can't resolve this:
|
||||
import { dbConfigSchema } from "../../shared/db/config.js";
|
||||
const ConfigSchema = av.object({ db: dbConfigSchema, ... });
|
||||
|
||||
// GOOD — inline the schema:
|
||||
const ConfigSchema = av.object({
|
||||
db: av.object({
|
||||
driver: av.enum_(["sqlite", "postgres"] as const).default("postgres"),
|
||||
host: av.string().default("postgres"),
|
||||
// ...
|
||||
}, { unknownKeys: "strip" }),
|
||||
// ...
|
||||
});
|
||||
```
|
||||
|
||||
### Nested Config Objects
|
||||
- Config supports nested `av.object()` — use for grouping related fields:
|
||||
```yaml
|
||||
config:
|
||||
db:
|
||||
driver: postgres
|
||||
host: postgres
|
||||
host: 0.0.0.0
|
||||
port: 18080
|
||||
```
|
||||
- Access via `this.config.db.driver`, `this.config.host`
|
||||
|
||||
### Config Defaults
|
||||
- BSB does NOT apply anyvali schema defaults for keys missing from sec-config.yaml
|
||||
- Always declare config values explicitly in sec-config.yaml
|
||||
- Defaults in the schema are documentation, not runtime fallbacks
|
||||
|
||||
### No Environment Variable Access
|
||||
- Application code should **never** read `process.env`
|
||||
- All config comes from sec-config.yaml via `this.config.*`
|
||||
- For Docker/Coolify: use build-time `envsubst` on a template to generate sec-config.yaml
|
||||
- sec-config.yaml should be baked into the image or bind-mounted — not generated at runtime
|
||||

|
||||
## Plugin Architecture
|
||||
|
||||
### What Should Be a Plugin
|
||||
- Services with own port, lifecycle, independent scaling
|
||||
- Examples: HTTP server, WebSocket server, API server
|
||||
|
||||
### What Should NOT Be a Plugin
|
||||
- Database access layer (just a library — no port, no lifecycle)
|
||||
- Shared utilities, crypto helpers, auth logic
|
||||
- Anything that's just a function other plugins call
|
||||
|
||||
### Cross-Plugin Communication
|
||||
- Plugins should have **zero runtime imports** from other plugins
|
||||
- Type-only imports (`import type { ... }`) are acceptable
|
||||
- Communication between plugins: BSB event bus (emitBroadcast, emitReturnableEvent)
|
||||
- Shared code goes in `src/shared/` — imported by multiple plugins as a library
|
||||
|
||||
### Plugin Init Order
|
||||
- `initAfterPlugins` / `initBeforePlugins` control order
|
||||
- Not needed when plugins are independent (each inits own DB, etc.)
|
||||
|
||||

|
||||
|
||||
## Build System
|
||||
|
||||
### Build Command
|
||||
```bash
|
||||
cross-env NODE_OPTIONS="--import tsx" bsb-plugin-cli build
|
||||
```
|
||||
- BSB build needs `tsx` for schema extraction from TypeScript source
|
||||
- Build output: `lib/` directory with compiled JS + `bsb-plugin.json`
|
||||
|
||||
### bsb-plugin.json
|
||||
- Auto-generated by build, lists all discovered plugins
|
||||
- Must match the plugins present in `src/plugins/`
|
||||
- If a plugin is removed, this file must be regenerated
|
||||
|
||||
### Dev Mode
|
||||
```bash
|
||||
cross-env NODE_OPTIONS="--import tsx" bsb-plugin-cli dev
|
||||
```
|
||||
- Hot reload, runs TypeScript directly
|
||||
- Creates `.bsbdevwatch` file for include/exclude patterns
|
||||
|
||||

|
||||
|
||||
## Logging
|
||||
|
||||
### Log Message Format
|
||||
- `obs.log.info("text {tag}", { tag: value })` — structured logging
|
||||
- Message strings **MUST be string literals** (BSB SmartLogMeta extracts placeholders from literal type)
|
||||
- String concatenation (`"a " + "b"`) widens to `string` and breaks SmartLogMeta placeholder extraction
|
||||
- Template literals in log messages work for the value, not the message key
|
||||
|
||||
```typescript
|
||||
// BAD:
|
||||
obs.log.info("connecting to " + url, {});
|
||||
|
||||
// GOOD:
|
||||
obs.log.info("connecting to {url}", { url });
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Docker Deployment Pattern
|
||||
|
||||
### Dockerfile Structure
|
||||
```dockerfile
|
||||
# Builder — compile TypeScript + native deps
|
||||
FROM node:24-trixie-slim AS builder
|
||||
WORKDIR /app
|
||||
# ... npm ci, npm run build ...
|
||||
|
||||
# Runtime — BSB container
|
||||
FROM betterweb/service-base:9
|
||||
|
||||
# Install extras (Alpine)
|
||||
RUN apk add --no-cache gettext ffmpeg
|
||||
|
||||
# Copy built plugin into BSB's node_modules
|
||||
COPY --from=builder /app/server/package.json /home/bsb/node_modules/<pkg>/package.json
|
||||
COPY --from=builder /app/server/bsb-plugin.json /home/bsb/node_modules/<pkg>/bsb-plugin.json
|
||||
COPY --from=builder /app/server/lib /home/bsb/node_modules/<pkg>/lib
|
||||
COPY --from=builder /app/node_modules /home/bsb/node_modules/<pkg>/node_modules
|
||||
|
||||
# Generate config from template
|
||||
COPY sec-config.template.yaml /tmp/sec-config.template.yaml
|
||||
RUN envsubst < /tmp/sec-config.template.yaml > /home/bsb/sec-config.yaml \
|
||||
&& chmod 444 /home/bsb/sec-config.yaml \
|
||||
&& rm /tmp/sec-config.template.yaml
|
||||
|
||||
ENV NODE_ENV=production
|
||||
ENV BSB_LIVE=true
|
||||
```
|
||||
|
||||
### sec-config.template.yaml Pattern
|
||||
- Template with `${VAR}` placeholders (NOT `${VAR:-default}` — envsubst doesn't support defaults)
|
||||
- Defaults come from Dockerfile `ARG` declarations
|
||||
- Secrets set as Coolify build args (not in git)
|
||||
- Template committed to public repo (safe — no secrets)
|
||||
- Generated sec-config.yaml baked into image at build time
|
||||
|
||||
---
|
||||
|
||||
## Common Pitfalls
|
||||
|
||||
1. **`betterweb/service-base:node` is v8, `:9` is v9** — use the correct tag
|
||||
2. **VOLUME declarations in base image shadow build-time COPY** — don't write to `/mnt/bsb-plugins`
|
||||
3. **`USER node` blocks BSB entrypoint** — entrypoint is at `/root/entrypoint.sh`, needs root access
|
||||
4. **Schema extractor can't follow imports** — inline schemas in plugin ConfigSchema
|
||||
5. **`package:` required in sec-config** — without it, BSB won't find external plugins
|
||||
6. **Alpine = apk, not apt-get** — base image is Alpine Linux
|
||||
7. **sec-config.yaml must be writable in dev, read-only in prod** — BSB_LIVE=true skips write attempts

# Multi-Tenant Architecture
|
||||
|
||||
## Current Design
|
||||
|
||||
- **Single admin user** — global admin, full access to all tenants
|
||||
- **No per-tenant logins** — one admin manages everything
|
||||
- **Tenant = data isolation boundary** — each tenant gets its own PG schema
|
||||
- **Admin switches tenants** via dropdown in topbar (session-stored)
|
||||
- **User management deferred** — if/when we want per-tenant user logins, that's a separate feature
|
||||
|
||||
## How It Works
|
||||
|
||||
1. `PUBLIC_MIGRATIONS` create `tenants` + `global_admins` tables in `public` schema
|
||||
2. Each tenant gets a PG schema: `tenant_<slug>` (e.g. `tenant_acme`)
|
||||
3. `TENANT_MIGRATIONS` run inside each tenant schema (full table set per tenant)
|
||||
4. Admin creates tenants from the admin UI
|
||||
5. Middleware sets `search_path = tenant_<slug>` per request based on selected tenant
|
||||
6. All repo queries automatically scope to the active tenant's schema
|
||||
|
||||
## What's NOT Happening
|
||||
|
||||
- No per-tenant admin users (single global admin for now)
|
||||
- No tenant-specific auth (global session, tenant is just a context switch)
|
||||
- No tenant billing/limits enforcement (max_kiosks/max_cameras columns exist but unenforced)
|
||||
- No tenant API keys (all API keys are global)
|
||||
|
||||
## Future: Per-Tenant Users
|
||||
|
||||
When needed, add:
|
||||
- Per-tenant `users` table (already in TENANT_MIGRATIONS)
|
||||
- Login scoped to tenant (tenant slug in login URL or selection)
|
||||
- Role-based access per tenant
|
||||
- Separate from global admin
