const client = new OutlineVPN({
  apiUrl: "https://your-server.com/api",
  fingerprint: "your-server-certificate-fingerprint",
});

Server Management

Get Server Info

// Returns: Server details including name, ID, metrics status etc.
const server = await client.getServer();

Rename Server

const success = await client.renameServer("My Server");

Configure Server Settings

Set Hostname

const success = await client.setHostnameForAccessKeys("example.com");

Set Default Port

const success = await client.setPortForNewAccessKeys(12345);

Manage Data Limits

// Set default data limit for new keys
await client.setDefaultDataLimit(1000000000); // 1GB in bytes

// Remove default data limit
await client.deleteDefaultDataLimit();

Access Key Management

List Access Keys

const accessKeys = await client.getAccessKeys();

Create Access Key

// Create with default settings
const key = await client.createAccessKey();

// Create with custom options
const customKey = await client.createAccessKey({
  name: "Custom Key",
  password: "custom-password",
  port: 8388,
});

// Create with specific ID
const keyWithId = await client.createAccessKeyWithId("custom-id", {
  name: "Named Key",
});

Manage Existing Access Key

// Get specific key
const key = await client.getAccessKey("key-id");

// Rename key
await client.renameAccessKey("key-id", "New Name");

// Set data limit for key
await client.addDataLimit("key-id", 1000000000); // 1GB

// Remove data limit
await client.deleteDataLimit("key-id");

// Delete key
await client.deleteAccessKey("key-id");

Metrics

Usage Statistics

// Get data usage per access key
const usage = await client.getDataUsage();

// Get metrics sharing status
const metrics = await client.getShareMetrics();

// Enable/disable metrics sharing
await client.setShareMetrics(true);

Error Handling

The API throws several types of errors:

try {
  await client.getAccessKey("non-existent");
} catch (error) {
  if (error instanceof NotFoundError) {
    // Handle 404
  } else if (error instanceof ValidationError) {
    // Handle validation errors
  } else if (error instanceof OutlineError) {
    // Handle other API errors
  }
}
