node-lambda

Command line tool to locally run and deploy your node.js application to Amazon Lambda.

node-lambda run

Installation

npm install -g node-lambda

Example App

The node-lambda-template example app makes it easy to get up and running.

Usage

There are 3 available commands.

node-lambda setup
node-lambda run
node-lambda deploy

Commands

setup

Initializes the event.json, .env files, and deploy.env files. event.json is where you mock your event. .env is where you place your deployment configuration. deploy.env has the same format as .env, but is used for holding any environment/config variables that you need to be deployed with your code to Lambda but you don't want in version control (e.g. DB connection info).

$ node-lambda setup --help

  Usage: run [options]

  Options:

    -h, --help                     output usage information

After running setup, it's a good idea to gitignore the generated event.json and .env files.

echo ".env\ndeploy.env\nevent.json" >> .gitignore

run

Runs your Amazon Lambda index.js file locally. Passes event.json data to the Amazon Lambda event object.

$ node-lambda run --help

  Usage: run [options]

  Options:

    -h, --help                     output usage information
    -h, --handler [index.handler]  Lambda Handler {index.handler}
    -j, --eventFile [event.json]   Event JSON File

deploy

Bundles and deploys your application up to Amazon Lambda.

Custom Environment Variables

AWS Lambda doesn't let you set environment variables for your function, but in many cases you will need to configure your function with secure values that you don't want to check into version control, for example a DB connection string or encryption key. Use the sample deploy.env file in combination with the --configFile flag to set values which will be prepended to your compiled Lambda function as process.env environment variables before it gets uploaded to S3.
