This project is just an example of simple Single Repo Multi Service Serverless Framework configuration with usage of MongoDB, Node.js, Serverless Bundle.
To run functionality locally I have used Serverless Offline plugin. It helps fast and reliable run your functions and test it before deployment.
Remember to have installed AWS CLI and give access to S3 so your files can be uploaded.
To run service just enter to service folder:
cd services/core
# Run Serverless Offline
sls offline
To deploy code to AWS you can use or deploying by calling serverless deploy at each service through terminal.
But I suggest to use Seed.Run. Its optimized for single repo multi service Serverless Framework applications to make deployments easy.
