# Phoenix OTel Development
OpenTelemetry registration and provider lifecycle layer for Phoenix. Single source of truth for OTel configuration — other Phoenix packages delegate here rather than importing OTel packages directly.
Read existing code in the directory you're working in before writing new code.
## Rule Files
| Rule file | When to read |
| ------------------------------------ | --------------------------------------------------------------------- |
| `rules/global-provider-lifecycle.md` | Global provider attachment, detachment, snapshot/restore, mount stack |
| `rules/register-api.md` | `register()`, span processor setup, public API surface |
| `rules/testing.md` | Tests for provider lifecycle, registration, span export |
## Build and Test
```bash
cd js/
pnpm --filter phoenix-otel test
```
Dual-module output (CJS + ESM). Tests use **vitest**.
