AWS lambda upload & AWS Steps to treat uploaded files

We already have a project deployed to AWS Lambda with serverless framework and some scripts in CloudFormations to deploy our Infraestructure. (S3, Network, RDS Aurora Serverless, etc...)

We want to add the deployment of a new enpoint, to get a PDF and a JSON from POST Petition.

This Endpoint should create a detailed workflow:

0. Client Open a websocket (store information about web socket)

1. Get The file, analyze the file, add file details (size, md5, originalName) to database, store it to S3 and store an Event to a SQS Queue (or other Event based trigger)

2. Launch a AWS Step process with several steps consisting in

- 3. Verify the file type (PDF, Compatible LibreOffice file, Image, Other)

- 4.1. If Other throw an error

- 4.2. If it is PDF copy it to output S3 folder

- 4.3. If it is a LibreOffice compatible layer, transform it to PDF (lambda already existing)

- 4.4 If it is an Image, transform it to PDF

- 5. Create a thumbnail image for each page of the resultant PDF

- 6. On finish notify by web socket to the customer

The project consists in:

- Create the Cloudformation script that deploy the serverless that create the associated Lambdas.

- Create the Cloudformation script that deploys the AWS step confguration

- Create the typescript lambdas with serverless to create the proposed flow.

- Test it from a front-end petition

The final output will require step-by-step documentation, configured [login to view URL] and aws configuration and deployment scripts
