## Installation

### npm

```bash
npm install @openstatus/sdk-node
```

### JSR

```bash
npx jsr add @openstatus/sdk-node
```

### Deno

```typescript
import { createOpenStatusClient } from "jsr:@openstatus/sdk-node";
```

## Quick Start

```typescript
import {
  createOpenStatusClient,
  HTTPMethod,
  NumberComparator,
  Periodicity,
  Region,
} from "@openstatus/sdk-node";

// Create a client with your API key
const client = createOpenStatusClient({
  apiKey: process.env.OPENSTATUS_API_KEY,
});

// Create a monitor
const { monitor } = await client.monitor.v1.MonitorService.createHTTPMonitor({
  monitor: {
    name: "My API",
    url: "https://api.example.com/health",
    periodicity: Periodicity.PERIODICITY_1M,
    method: HTTPMethod.HTTP_METHOD_GET,
    regions: [Region.FLY_AMS, Region.FLY_IAD, Region.FLY_SYD],
    active: true,
    statusCodeAssertions: [
      { comparator: NumberComparator.EQUAL, target: BigInt(200) },
    ],
  },
});

console.log(`Monitor created: ${monitor?.id}`);

// List all monitors
const { httpMonitors, tcpMonitors, dnsMonitors, totalSize } = await client
  .monitor.v1.MonitorService.listMonitors({});

console.log(`Found ${totalSize} monitors`);
```

## Authentication

All API requests require an API key. Get yours from the
[OpenStatus dashboard](https://www.openstatus.dev/app).

### Recommended: Configure client once

```typescript
import { createOpenStatusClient } from "@openstatus/sdk-node";

const client = createOpenStatusClient({
  apiKey: process.env.OPENSTATUS_API_KEY,
});

// No need to pass headers on each call
await client.monitor.v1.MonitorService.listMonitors({});
```

### Alternative: Manual headers

```typescript
import { openstatus } from "@openstatus/sdk-node";

const headers = {
  "x-openstatus-key": process.env.OPENSTATUS_API_KEY,
};

// Pass headers to each service method
await openstatus.monitor.v1.MonitorService.listMonitors({}, { headers });
```

### Environment Variables

| Variable             | Description             | Default                          |
| -------------------- | ----------------------- | -------------------------------- |
| `OPENSTATUS_API_KEY` | Your OpenStatus API key | Required                         |
| `OPENSTATUS_API_URL` | Custom API endpoint     | `https://api.openstatus.dev/rpc` |

## SDK Reference

> **Note:** All examples below assume you've created a client:
>
> ```typescript
> const client = createOpenStatusClient({
>   apiKey: process.env.OPENSTATUS_API_KEY,
> });
> ```

### Assertions

#### Status Code Assertions

Validate HTTP response status codes using `NumberComparator`.

```typescript
import { NumberComparator } from "@openstatus/sdk-node";

{
  statusCodeAssertions: [
    { comparator: NumberComparator.EQUAL, target: BigInt(200) },
    { comparator: NumberComparator.LESS_THAN, target: BigInt(400) },
  ];
}
```

#### Body Assertions

Validate response body content using `StringComparator`.

```typescript
import { StringComparator } from "@openstatus/sdk-node";

{
  bodyAssertions: [
    { comparator: StringComparator.CONTAINS, target: '"status":"ok"' },
    { comparator: StringComparator.NOT_EMPTY, target: "" },
  ];
}
```

#### Header Assertions

Validate response headers using `StringComparator`.

```typescript
import { StringComparator } from "@openstatus/sdk-node";

{
  headerAssertions: [
    {
      key: "content-type",
      comparator: StringComparator.CONTAINS,
      target: "application/json",
    },
  ];
}
```

## Error Handling

The SDK uses Connect RPC. Errors include a `code` and `message`:

```typescript
import { ConnectError } from "@connectrpc/connect";

try {
  await client.monitor.v1.MonitorService.deleteMonitor({ id: "invalid" });
} catch (error) {
  if (error instanceof ConnectError) {
    console.error(`Error ${error.code}: ${error.message}`);
  }
}
```
