gulp-awslambda

gulp-awslambda

A Gulp plugin for publishing your package to AWS Lambda

Install

$ npm install --save-dev gulp-awslambda

Usage

AWS Credentials

It is recommended that you store your AWS Credentials in ~/.aws/credentials as per the docs.

Basic Workflow

gulp-awslambda accepts a single ZIP file, uploads that to AWS Lambda, and passes it on down the stream. It works really well with gulp-zip:

var gulp   = require('gulp');
var lambda = require('gulp-awslambda');
var zip    = require('gulp-zip');

gulp.task('default', function() {
	return gulp.src('index.js')
		.pipe(zip('archive.zip'))
		.pipe(lambda(lambda_params, opts))
		.pipe(gulp.dest('.'));
});

For more information on lambda_params and opts see the API section.

Example Project

See the example/ directory of this repo for a full working example.

API

lambda(lambda_params, opts)

lambda_params

Parameters describing the Lambda function. This can either be...

A String

corresponding to the name of an existing Lambda function. In this case gulp-awslambda will only update the function's code.

An Object

that is exactly the same as you would pass to updateFunctionConfiguration(). The only required parameters are FunctionName and Role. All the other parameters have the following default values:

• Handler = 'index.handler': This assumes a valid exports.handler in index.js at the root of your ZIP
• Runtime = 'nodejs': Currently the only supported runtime

gulp-awslambda will perform an upsert, meaning the function will be created if it does not already exist, and updated (both code and configuration) otherwise.

opts

Options configuring the AWS environment to be used when uploading the function. The following options are supported:

profile

If you use a different credentials profile, you can specify its name with this option.

region = 'us-east-1'

Set your AWS region.
