Serverless Stack Output Plugin


A serverless plugin to store output from your AWS CloudFormation Stack in JSON/YAML/TOML files, or to pass the output to a JavaScript function for further processing.

Usage

$3

``bash
$ > yarn add serverless-stack-output
`

`bash
$ > npm install serverless-stack-output
`

$3

`yaml
plugins:
- serverless-stack-output

custom:
output:
handler: scripts/output.handler # Same syntax as you already know
file: .build/stack.toml # toml, yaml, yml, and json format is available
`

$3

Based on the configuration above the plugin will search for a file scripts/output.js with the following content:

`js
function handler (data, serverless, options) {
console.log('Received Stack Output', data)
}

module.exports = { handler }
`

$3

Just name your file with a .json, .toml, .yaml, or .yml extension, and the plugin will take care of formatting your output. Please make sure the location where you want to save the file exists!

Example

The plugins works fine with serverless functions, as well as when using custom CloudFormation resources. The following example configuration will deploy an AWS Lambda function, API Gateway, SQS Queue, IAM User with AccessKey and SecretKey, and a static value:
