Usage

const { compose, createLambda } = require('pambda');
const { aws } = require('pambda-aws');

exports.handler = createLambda(
  compose(
    aws({
      serviceConfigs: {
        ses: { region: 'us-west-2' }
      },
    }),

    // Subsequent pambdas can obtain instances of AWS service from context.
    next => (event, context, callback) => {
      const dynamodb = context.DynamoDB;

      // This SES uses in the Oregon region.
      const ses = context.SES;
    }
  )
);

aws(options = {})

Generate and return a pambda to add AWS service properties to context.

The pambda uses lazy-aws-service to add properties.

Since added properties are delayed initialized, instances of unused services will not be created.
