Best local development workflow for the tutorial

[jayco]

Hey guys - I have just completed the tutorial and love it!

What is the best local development workflow for the tutorial. It is important for me to be able to set up a local development environment that can be used offline. Has anyone setup an environment with the services used in the AWS tutorial:

• Cognito
• S3
• API
• Dynamo

I am guessing mocking out urls or event.requestContext.identity and possibly running localstack.

Any help would be greatly appreciated

Ok to answer my own question and for anyone that stumbles upon this looking for a quick setup, so you can run and debug the functions locally - this works:

• Set headers in client for cognito eg… cognito-identity-id: USER-SUB-1234
• Run dynamo db locally either using localstack or https://github.com/99xt/serverless-dynamodb-local/tree/v1
  Note:
  • There is an issue with this you will need to pin the install https://github.com/serverless/serverless/issues/3247 see the last comment for the stackoverflow fix (that worked for me)
  • You need to set migration to true in the serverless.yml, even if you dont seed or it will not generate the table

I just used the data out of the mocks to post and retrieve notes - worked pretty easy.

There is also an example on https://github.com/serverless/examples/tree/master/aws-node-rest-api-with-dynamodb-and-offline (new members can only post 2 links)

Awesome! Thank you for sharing. We should turn this into a chapter for other folks!
