LTIaaS Launch™ Node.js SDK

The LTIAAS Launch™ Node.js SDK is a comprehensive client library that provides easy integration with the LTIAAS platform for managing LTI (Learning Tools Interoperability) connections between learning platforms and tools.

The SDK handles all the complex LTI protocol requirements while providing a clean, intuitive interface for developers to build LTI tool integrations. It supports both LTI 1.3 and legacy versions, making it versatile for different integration needs.

More information about the LTIAAS platform can be found at https://ltiaas.com.

Authentication

The SDK supports three authentication methods:

• LTIK Token Authentication
• Service Key Authentication
• API Key Authentication

Authentication Examples

// LTIK Authentication
const client = new LaunchClient({
  apiKey: "your-api-key",
  ltik: "your-ltik-token"
});

// Service Key Authentication
const client = new LaunchClient({
  apiKey: "your-api-key",
  serviceKey: "your-service-key"
});

// API Key Authentication
const client = new LaunchClient({
  apiKey: "your-api-key"
});

Error Handling

The SDK includes built-in validation and error handling. For example, when using incorrect session types:

// This will throw InvalidSessionError if using wrong authentication type
try {
  await client.getIdToken(); // Requires LTIK authentication
} catch (error) {
  if (error instanceof InvalidSessionError) {
    console.error(`Current session: ${error.currentSession}`);
    console.error(`Allowed sessions: ${error.allowedSessionTypes.join(', ')}`);
  }
}

Core Methods

All of the LTIAAS API methods are available through the SDK. For more information about the LTIAAS API, refer to the [LTIAAS Launch™ API Documentation](https://ltiaas.com/api/ltiaas.

Example Usage

// Update platform configuration
const updatedPlatform = await client.updatePlatform("platform-123", {
  name: "Updated Canvas Instance",
  clientId: "new-client-id",
  deploymentId: "new-deployment-id",
  authenticationEndpoint: "https://canvas.example.com/auth"
});

// Access updated platform data
console.log(updatedPlatform.name);
console.log(updatedPlatform.active);
console.log(updatedPlatform.updatedAt);

deletePlatform

Permanently removes a platform integration from your LTIaaS account. This method requires API Key authentication.

Notes:

• This action cannot be undone
• All associated data with the platform will be removed
• Active integrations using this platform will stop working

Parameters

Parameter	Type	Required	Description
id	string	Yes	The unique identifier of the platform to delete

Return Type

Returns a Promise that resolves to void. The platform will be permanently deleted if the operation is successful.

Example Usage

// Delete a platform by ID
await client.deletePlatform("platform-123");

// Delete with error handling
try {
  await client.deletePlatform("platform-123");
  console.log("Platform successfully deleted");
} catch (error) {
  console.error("Failed to delete platform:", error);
}

activatePlatform

Activates a registered LTI platform, enabling it to process launches and service requests. This method requires API Key authentication.

Parameters

Parameter	Type	Required	Description
id	string	Yes	The unique identifier of the platform to activate

Return Type

Returns a Promise that resolves to void. The operation is considered successful if no error is thrown.

Note:

• The platform must be registered before it can be activated
• Only inactive platforms can be activated
• This operation is idempotent - activating an already active platform will not cause an error

Example Usage

// Activate a platform
await client.activatePlatform("platform-123");

// Can be used in combination with platform registration
const platform = await client.registerPlatform({
  name: "Canvas Instance",
  url: "https://canvas.instructure.com"
});
await client.activatePlatform(platform.id);

deactivatePlatform

Deactivates a specific LTI platform integration, preventing further launches and interactions. This method requires API Key authentication.

Notes:

• The platform can be reactivated using the activatePlatform method
• Deactivating a platform will immediately stop all active LTI launches
• The platform ID must be valid and exist in your LTIaaS account

Parameters

Parameter	Type	Required	Description
id	string	Yes	The unique identifier of the platform to deactivate

Return Type

Returns a Promise that resolves to void. The operation is considered successful if no error is thrown.

Example Usage

// Deactivate a platform
await client.deactivatePlatform("platform-123");
