Want to reduce chafing when using Sails actions inside of AWS Lambda? Baggywrinkle is the answer!

Baggywrinkle builds a modified version of a machine that proxies its inputs from the Lambda function's event argument, and proxies its exits through the Lambda function's callback. It is intended to be used with Lambda functions that are triggered via the AWS API Gateway (that is, via HTTP requests).

$ npm install baggywrinkle --save

Usage

var lambdaFunction = require('baggywrinkle')(actionMachine);

Example

// handler.js
var asLambda = require('baggywrinkle');

module.exports = asLambda({
  inputs: {
    name: {
      example: 'Joe',
      description: 'The person to greet'
    }
  },
  exits: {
    success: {
      statusCode: 200,
      description: 'Greeting was successful!'
    }
  }
  fn: function (inputs, exits) {
    return exits.success(`Hello ${inputs.name}!`);
  }
});

Note that the input to Baggywrinkle can be either:

• a machine definition compatible with machine-as-action or
• a machine instance generated by machine-as-action

Options

For available options, see the machine-as-action documentation. Note however that Baggywrinkle does not currently support:

• The view response type
• The redirect response type
• Custom Sails response types such as badRequest
• File uploads
• Streaming
