Customising deployments

Claudia has lots of options to customise deployments. You can configure the function name, reserved memory, timeouts and a lot more by providing additional options to the claudia create command. To get a full list of supported options, check out the Claudia Create Docs or run:

claudia create --help

Check out these tutorials for information on customising deployments:

Working with API Gateway web APIs

Claudia can create an API Gateway definition, wire up integration templates and even simplify routing so that a single Lambda function can handle multiple web API URLs. For that, create a WEB API module using the Claudia API Builder and supply the routing module name instead of a handler to create the project:

claudia create --name LAMBDA_NAME --region AWS_REGION --api-module ROUTING_MODULE

See the Web Api Example Project for a trivial example of how to wire up a single lambda to multiple HTTP paths.

Working with pre-existing lambda/API gateway resources

Claudia can also work with objects you've already created in AWS. In order to connect correctly to the resources, you'll need to create a claudia.json file in the root directory of your Node.js project, and set the following parameters:

  • lambda: required, an object containing the following properties
    • name: lambda function name
    • role: primary IAM security role that is assumed by the lambda function
    • region: AWS region where the function is defined
  • api: (optional) API Gateway REST API details
    • id: REST API Id
    • module: the module that contains the API definition

Example configuration

{
  "lambda": {
    "name": "hello-world",
    "role": "hello-world-executor",
    "region": "us-east-1"
  },
  "api": {
    "id": "25628xa",
    "module": "web"
  }
}
