Package Exports

node-serverless-helpers

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-serverless-helpers) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Node Serverless Helpers

Node Serverless Helpers is a package meant to make your life easier when developing lambda functions in NodeJS. It handles events seamlessly and adds useful defaults, helpers and functions to your project.

Documentation

The documentation can be found in the Wiki.

Usage

Install the package with npm or yarn.

npm install node-serverless-helpers
# or 
yarn add node-serverless-helpers

Here is a sample working code.

// handler.js
'use strict';

const handle = require('node-serverless-helpers').handle;

module.exports.helloWorld = handle(async (event) => {
    return 'hello lambda world!';
});

# serverless.yaml
service: hello-world

provider:
  name: aws
  runtime: nodejs8.10
  region: us-east-1

functions:
  hello:
    handler: handler.helloWorld
    events:
      - http:
          path: ''
          method: get

The important part is the handle function that does 3 things.

Run the init function. You can register init handlers by calling the register function.
Run the front controller. Its job is to figure out what source the event comes from, and add useful middlewares to it.
Run your function, and wrap the result to the expected format.

TODO

Global logging system
Implement middlewares for API
Implement more handlers
Remove all console.logs
