# `node:stream/promises`

## Import

```js
import stream_promises from "nstdlib/stream/promises";
```

> [!NOTE]
> Its behavior matches Node.js.

## Runtime support

| Where it runs | Status | Export coverage | Details |
| ------------- | ------ | --------------- | ------- |
| **nstd** | ⚠️ some support | – | 199/219 of Node's own eligible tests pass under nstd (filed under `stream`, the parent module). |
| **Browser** | ❔ not tested | 100% of Node.js | It imports with the small process shim. 2/2 Node.js exports are available. No module-specific behavior test ran. |
| **Node.js (host)** | ✅ works | 100% of Node.js | 2/2 exports. |

## Exports (2 of 2)

Each cell shows what happens when code reads an export:

- ✅ Available through every import style. A named error also counts.
- ⚠️ Available through only some import styles.
- ❔ The export exists but has no value.
- ❌ The export does not exist.
- – This environment was not measured.
