lambda

Simple wrapper around the @aws-sdk/client-lambda library to invoke AWS Lambda functions with Cloudevents.

Usage

Node

<script src="https://unpkg.com/@1mill/[email protected]/dist/index.umd.js"></script>

or

npm install @1mill/lambda

const { Lambda } = require('@1mill/lambda') // CommonJS
import { Lambda } from '@1mill/lambda' // EMS

const lambda = new Lambda({
  accessKeyId: 'required' || process.env.MILL_LAMBDA_AWS_ACCESS_KEY_ID,
  endpoint: 'optional' || process.env.MILL_LAMBDA_AWS_ENDPOINT,
  region: 'required' || process.env.MILL_LAMBDA_AWS_REGION,
  secretAccessKey: 'required' || process.env.MILL_LAMBDA_AWS_SECRET_ACCESS_KEY,
  sessionToken: 'optional' || process.env.AWS_SESSION_TOKEN,
})

| | Required | Default | Notes | |-----------------|----------|---------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------| | accessKeyId | yes | process.env.MILL_LAMBDA_AWS_ACCESS_KEY_ID || process.env.AWS_ACCESS_KEY_ID || process.env.AWS_ACCESS_KEY | | | endpoint | | process.env.MILL_LAMBDA_AWS_ENDPOINT || process.env.AWS_ENDPOINT | Good for local development environment when using Localstack (or other AWS simulators) | | region | yes | process.env.MILL_LAMBDA_AWS_REGION || process.env.AWS_REGION | | | secretAccessKey | yes | process.env.MILL_LAMBDA_AWS_SECRET_ACCESS_KEY || process.env.AWS_SECRET_ACCESS_KEY | | | sessionToken | | process.env.AWS_SESSION_TOKEN | |

const lambda = new Lambda({...})

await lambda.invoke({
  cloudevent,
  functionName: 'required-my-lambda-arn',
  invocationType: 'optional' || 'Event',
})

| | Required | Default | Notes | |----------------|----------|---------|------------------------------------------| | cloudevent | yes | | @1mill/cloudevents | | functionName | yes | | | | invocationType | | 'Event' | Options are 'Event' or 'RequestResponse' |
