Running webpack for local testing

Hi, I have created a local js file with its dependency getting import in the handler.js as below

import JsonValidator from './src/jsonvalidator'

Now when i run this on local for testing purpose using mock event json. I'm getting error import undrfined error

This is because i assume the code is not getting transpiled in local and only when it gets deployed.

So how do i transpile my code for local debugging and testing ?

@goldytech It does transpile on local. We cover this in the tutorial. In this chapter for example - https://serverless-stack.com/chapters/add-a-get-note-api.html. When we run the serverless invoke local --function get --path mocks/get-event.json, it transpiles the given function handler.

I've pushed my code on Github https://github.com/goldytech/aws-serverless When i run the command serverless invoke local --function hello --path mocks/data-event.json

I get this error

@goldytech I tried your repo. YAML is really strict, this line https://github.com/goldytech/aws-serverless/blob/master/serverless.yml#L21 should be - serverless-webpack.
