## Importing constructs

You can either import specific constructs in your app.

```

Or import them all.

```js
import * as sst from "@serverless-stack/resources";
```

## Types of constructs

SST comes with a two types of constructs.

### Low-level

These either extend or replace the native CDK constructs.

- [`App`](https://docs.sst.dev/constructs/App)
- [`Stack`](https://docs.sst.dev/constructs/Stack)
- [`Function`](https://docs.sst.dev/constructs/Function)

### Higher-level

These are higher level abstractions that wrap around multiple constructs to serve specific use cases.

- [`Api`](https://docs.sst.dev/constructs/Api)
- [`Auth`](https://docs.sst.dev/constructs/Auth)
- [`Cron`](https://docs.sst.dev/constructs/Cron)
- [`Table`](https://docs.sst.dev/constructs/Table)
