## Installation

### JSR

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

### npm

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

### Deno

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

## Quick Start

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

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

// Create a monitor
const { monitor } = await openstatus.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) },
        ],
      },
    },
    { headers },
  );

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

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

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

## Authentication

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

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

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

## Environment Variables

## Assertions

All assertion comparators are exported as enums from the SDK.

### 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) },
  ];
}
```

**NumberComparator values:**

| Enum Value              | Description           |
| ----------------------- | --------------------- |
| `EQUAL`                 | Equal to target       |
| `NOT_EQUAL`             | Not equal to target   |
| `GREATER_THAN`          | Greater than target   |
| `GREATER_THAN_OR_EQUAL` | Greater than or equal |
| `LESS_THAN`             | Less than target      |
| `LESS_THAN_OR_EQUAL`    | Less than or equal    |

### 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: "" },
  ];
}
```

**StringComparator values:**

| Enum Value              | Description                 |
| ----------------------- | --------------------------- |
| `CONTAINS`              | Contains target string      |
| `NOT_CONTAINS`          | Does not contain target     |
| `EQUAL`                 | Equal to target             |
| `NOT_EQUAL`             | Not equal to target         |
| `EMPTY`                 | Body is empty               |
| `NOT_EMPTY`             | Body is not empty           |
| `GREATER_THAN`          | Lexicographically greater   |
| `GREATER_THAN_OR_EQUAL` | Lexicographically >= target |
| `LESS_THAN`             | Lexicographically less      |
| `LESS_THAN_OR_EQUAL`    | Lexicographically <= 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",
    },
  ];
}
```

### DNS Record Assertions

Validate DNS records using `RecordComparator`.

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

{
  recordAssertions: [
    {
      record: "A",
      comparator: RecordComparator.EQUAL,
      target: "93.184.216.34",
    },
    { record: "CNAME", comparator: RecordComparator.CONTAINS, target: "cdn" },
  ];
}
```

**RecordComparator values:**

| Enum Value     | Description             |
| -------------- | ----------------------- |
| `EQUAL`        | Equal to target         |
| `NOT_EQUAL`    | Not equal to target     |
| `CONTAINS`     | Contains target string  |
| `NOT_CONTAINS` | Does not contain target |

**Supported record types:** `A`, `AAAA`, `CNAME`, `MX`, `TXT`

## Regions

Monitor from 28 global locations across multiple providers. Use the `Region`
enum:

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

// Example: Use specific regions
regions: [Region.FLY_AMS, Region.FLY_IAD, Region.KOYEB_FRA];
```

## Error Handling

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

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

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