Lambda/Serverless Functions

This document describes how to manage and execute Lambda/Serverless functions using the Qelos platform.

Before creating functions, you can verify that the underlying AWS or Cloudflare integration source's credentials actually work with checkStatus.

Listing Functions

You can list all the functions for a given integration source.

const functions = await qelos.administrator.manageLambdas.getList('sourceId');

Getting a Function

You can get a specific function by its name.

const func = await qelos.administrator.manageLambdas.getLambda('sourceId', 'functionName');

Creating a Function

You can create a new function.

const newFunc = await qelos.administrator.manageLambdas.create('sourceId', {
  name: 'my-new-function',
  runtime: 'nodejs18.x',
  description: 'My new function',
  // AWS specific
  handler: 'index.handler',
  role: 'arn:aws:iam::123456789012:role/lambda-role',
  zipFile: Buffer.from('...'),
  // Cloudflare specific
  code: 'export default { fetch: () => new Response("Hello World!") }',
});

Updating a Function

You can update an existing function.

const updatedFunc = await qelos.administrator.manageLambdas.update('sourceId', 'functionName', {
  description: 'My updated function',
});

Deleting a Function

You can delete a function.

await qelos.administrator.manageLambdas.remove('sourceId', 'functionName');

Executing a Function

You can execute a function and get the result.

const result = await qelos.lambdas.execute('integrationId', {
  foo: 'bar',
});
