lambda-compare

Compare AWS Lambdas in different environments

About

Handling different AWS environments is not easy and managing many lambdas in those environments is even harder. lambda-compare allows to quickly compare relevant deployment information of the different lambdas.

IAM

Following IAM roles need to be configured for the credentials.

• Lambda - listFunctions

Install

$ npm install lambda-compare

Usage

const comparator = require('lambda-compare');

comparator.addAlias('development', {
	region: 'eu-west-1',
	accessKeyId: 'AKIAIOSFODNN7EXAMPLE'
	secretAccessKey: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY'
});

// {development: {region: 'eu-west-1', accessKeyId: 'AKIAIOSFODNN7EXAMPLE', secretAccessKey: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY'}}

comparator.listAliases({credentials: false})

// ['development']

comparator.listLambdas('development')
	.then(data => console.log(data))

// [{FunctionName: 'sales', LastModified: moment().format('YYYY-MM-DD')},{FunctionName: 'marketing', LastModified: moment().format('YYYY-MM-DD')}]

comparator.compare('development', 'production', {LastModified: true})
	.then(comparison => console.log(comparison))
