worker-pool-aws-sdk v0.1.0

Worker Pool for AWS SDK

Simple pool of workers to make API calls using the AWS SDK, while leveraging Node.js Worker threads.

This library uses Node.js Worker threads (it depends more specifically on Piscina.js).

Usage

Example

const STS = require('aws-sdk/clients/sts')
const WorkerPoolAwsSdk = require('worker-pool-aws-sdk');

const workerPool = new WorkerPoolAwsSdk();

(async function () {
  const sts = new STS({ region: 'us-east-1' });
  const result = await workerPool.runAwsTask({
    name: 'sts',
    options: sts.config,
    operation: 'getCallerIdentity',
  });
  console.log(result);
  /*
    Prints result in this shape:
    {
      Account: "123456789012", 
      Arn: "arn:aws:iam::123456789012:user/Alice", 
      UserId: "AKIAI44QH8DHBEXAMPLE"
    }
  */
})();

Development

Check out the master branch and install dependencies to get started:

npm ci --optional

Now that you have the dependencies installed, you can run this command in the root folder to compile the whole project.

npm run build

Linting is done via TypeScript ESLint and running unit tests via Jest. The continuous integration runs these checks, but you can run them locally with:

npm run lint
npm test
