PoC: NestJS. Serverless Framework. DynamoDB. Azure Functions.

NestJS Serverless App

This is a proof-of-concept app which utilizes the following projects/technologies.

Primary Tasks for PoC

• NestJS - NodeJS Framework.
• Serverless - Build applications with serverless architectures using AWS Lambda.
  • Azure Functions
  • Azure Functions scalability
• CosmosDB - Azure Cosmos DB is Microsoft’s globally distributed, multi-model database service for operational and analytics workloads.

Progress

Technology	Progress
NestJS	PoC Done
Serverless	PoC Done
CosmosDB	Not Started

Secondary Tasks for PoC

• docker-compose - It would be good to have it for local development.
  • This would be a good alternative since serverless offline does not support hot-reload (at least the way it's implemented right now in this repo). This should consider the use of offline CosmosDB?
• CosmosDB - Add support in serverless YAML file resources section?
• Swagger/openapi - Investigate how to auto-generate it with decorators, etc. (We should not think about maintaining it manually).
• Stages - Configure various deployment stages like dev, stg, prd.
• Routing - Configure domain routing, etc. via serverless resources (we do not need terraform if we can do all config via serverless YAML.)
• CircleCI - Add CI/CD support.
• DynamoDB trigger -> GCP BigQuery (or AWS redshift) for Data Analysis
• SMS auth (encrypt phone number if possible) - Please investigate only the encryption part, auth will be taken care of by Primary Tasks.
