@aesop-fables/triginta

triginta is a lightweight framework that wraps the basic infrastructure usages of AWS Lambda (SQS, Kinesis, etc.). For APIs, see our API framework. It aims to conventionalize logging, error handling, and X-Ray integration.

Installation

npm install @aesop-fables/triginta

yarn add @aesop-fables/triginta

Supported Lambdas

The following can be created via the ILambdaFactory interface:

• SQS Lambdas (createSqsLambda)
• S3 Lambdas (createS3Lambda)
• Kinesis Lambdas (createKinesisLambda)

Known issues

We're missing unit tests, logging, error handling, middleware support, and X-Ray integration. This will all come soon - I just wanted to get the basic structure published.

Example

// index.ts
interface MyQueuedMessage {
  message: string;
}

class MyLambda implements IHandler<MyQueuedMessage> {
  async handle(message: MyQueuedMessage): Promise<void> {
    console.log('HELLO, WORLD!');
    console.log(JSON.stringify(message, null, 2));
  }
}

// obviously you need to register all of your stuff
const container = bootstrap();
// triginta doesn't depend on containr but it abstracts out the creation of your handler
// so that you can easily plug it in (see the `factory` property)
const lambdaFactory = container.get<ILambdaFactory>();

export const handler = lambdaFactory.createSqsLambda<MyLambda>({
  factory: () => container.get<MyLambda>('lambda'),
});
