lambda-continuous-delivery

This module goal is to deploy:

• CloudFormation Stacks
• Lambda Functions

###Function flow:

1. Generate package: Finds recursively in each folder the file "package.json", if it's found, a deploy script is generated for that lambda function.
2. Execute NPM Scripts: Executes the script generated in the previous process.
3. Deploy Lambda Code: Generates a zip for each lambda function, then uploads it to S3 and finally deletes the zip.
4. Deploy CloudFormation Stack: Find all .json files in the folder where the stacks are saved and uploads it to S3.

###Deploy script

1. cd "Lambda folder": Move to the lambda function folder.
2. npm install: Install every package.
3. npm run cover: Execute tests and coverage report.
4. npm prune --production: Remove dev dependencies.
