Invoke Lambda Package

Utility function for calling microservices within APIs.

Usage

const invokeLambda = require('@growsari/invoke-lambda')

await invokeLambda('ms-some-project', 'create', { name: 'some-name', description: 'some-value'})

You may specify the API version and the region as named parameters after params. They will default to '2015-03-31' and process.env.AWS_DEFAULT_REGION respectively, if not defined.

Async

await invokeLambda('ms-some-project', 'create', { name: 'some-name', description: 'some-value'}, {async: true})

You can specify {async: true} to execute lambda asynchronously.

Details

Invokes the lambda named [service]-[stage]-[operation].

Assumptions

• process.env.AWS_DEFAULT_REGION is named in the project.
• process.env.IS_OFFLINE is true when deployed.
• When in offline mode, it is deployed through Docker deployment.
• process.env[``${service.toUpperCase()}-PORT``] is assigned to the deployment port of the specific service in the Docker deployment.
• The containing lambda has access to all of the lambdas named.
• Called function response has the following payload format

{
  data: Object,
  success: Boolean,
  message: String,
  code: any
}

so that the response will be identified properly as a success or a failure.
