gulp-lambda-deploy

Gulp plugin to deploy zipped packages to AWS Lambda directly or via S3

Install

$ npm install --save-dev gulp-lambda-deploy

Usage

gulp-lambda-deploy accepts a single zip file, which is uploaded to AWS Lambda either directly or via S3. After upload, the zip file is passed down the stream. I suggest using gulp-zip to create the zip file.

Here is the typical usage:

const gulp = require('gulp');
const lambda = require('gulp-lambda-deploy');
const zip = require('gulp-zip');

let params = {
    name: '...',
    role: '...',
    s3: {
        bucket: '...',
        key: '...'
    },
    subnets: [..., ...],
    securityGroups: '...'
};

let options = {
    profile: '...',
    region: '...'
};

gulp.task('default', function(cb) {
    return gulp.src('index.js')
        .pipe(zip('package.zip'))
        .pipe(lambda(params, options))
        .on('end', cb);
});

If the params.s3 object is not provided, then the zip file is uploaded directly to Lambda and is not stored in S3 as an intermediate step.

If a function with the name given in params.name does not already exist, then it is created, otherwise the existing code and configuration is updated for that function.

For more information on params and options see the API section.

AWS Credentials

Currently you must provide an AWS profile name that is stored in the Shared Credentials File at ~/.aws/credentials. For more info see the aws-sdk documentation.

API

gulp-lambda-deploy must be given exactly two arguments. The first is Lambda-specific parameters, and the second is options for AWS. Each has its own set of optional and required properties.

lambda(params, options);

params

These parameters are specific to the Lambda function you're uploading.

name (required)

The name of your function.

role (required)

The ARN of the role given to the Lambda function.

s3

An object indicating where to upload the function code to. If the s3 parameter is given, it must contain the properties bucket and key. These specify the upload location for the file within S3.

handler

The location of your method handler. Must be of the form [filename].[method name] where [method name] is exported. Defaults to index.handler.

runtime

The runtime for your code. Defaults to nodejs4.3.

publish

A boolean indidcating if you want to publish a new version of the function.

alias

The name of an alias to point to this function. If this alias doesn't already exist, it will be created.

description

A string describing the Lambda function.

timeout

The time in seconds that the function is allowed to run on each invocation.

memory

The amount of memory, in MB, your Lambda function is given.

subnets

The ids of subnets to create the Lambda function into, if you want to create it in a VPC (a string or an array of strings).

securityGroups

The security groups to add to the Lambda function if created in a VPC (a string or an array of strings).

options

Options for configuring the AWS environment.

profile (required)

The named AWS profile used to authenticate and interact with AWS services. Must be saved in Shared Credentials File. See the AWS Credentials section.

region (required)

The AWS region your resources will be located in.
