aws-lambda-layer

Easily provision Layers for AWS Lambda using Serverless Components.

1. Install
2. Create
3. Configure
4. Deploy

$3

``console
$ npm install -g @serverless/components
`

$3


`console
$ mkdir my-layer && cd my-layer
`

in the case of a nodejs layer, the directory should look something like this:


`
|- code
|- index.js # the root of your library
|- package.json # the main property should point to index.js in this example
|- serverless.yml
|- .env # your development AWS api keys
|- .env.prod # your production AWS api keys
`

the .env files are not required if you have the aws keys set globally and you want to use a single stage, but they should look like this.

`
AWS_ACCESS_KEY_ID=XXX
AWS_SECRET_ACCESS_KEY=XXX
`

`yml


serverless.yml

name: my-layer
stage: dev

myLayer:
component: "@serverless/aws-lambda-layer"
inputs:
name: my-layer
description: My Serverless Layer
code: ./code
regoin: us-east-1
runtimes: [ 'nodejs8.10' ] # the default is undefined (aka. all runtimes supported)

# a path prefix to all the files that would be included in the package
# this example would package a valid node dependency
# since this is the path expected by aws
prefix: nodejs/node_modules

# if you'd like to include any files outside the codebase
include:
- ../external/file.js

# specifying an existing deployment bucket would optimise deployment speed
# by using accelerated multipart uploads
bucket: my-deployment-bucket
`

`console
