What `preflight` found: three checks and whether a launch could proceed.

## Properties

### checks

```ts
checks: PreflightCheck[];
```

`region`, `credentials`, and `service`, in that order.

***

### ok

```ts
ok: boolean;
```

True exactly when no fatal check failed or was skipped.

***

### region?

```ts
optional region?: string;
```

The region checked, absent when none resolved.

## Provenance

This page is generated from `bindings/microvms-js/index.d.ts` by TypeDoc 0.28.20 and typedoc-plugin-markdown 4.13.1, run from `site/scripts/gen-reference.mjs` on every `pnpm run sync`, so an edit made here is overwritten by the next run.

To change the page, change the doc comment in the binding's Rust source, then regenerate the declarations with `mise run dts`. `mise run dts:check` fails when the committed file no longer matches the source.
