Not sure where to start

Alright finally I found out a method (it's very raw) to locally test dynamodb

I have this version: "serverless-dynamodb-local": "^0.2.37"

serverless.yml custom parameters:

dynamodb:
  stages:
    - ${self:provider.stage}
  start:
    port: 8000
    inMemory: true
    migrate: true
    #noStart: true
  migration:
    dir: offline/migrations

My lambda runs this configuration:

let options = {};

if (process.env.IS_OFFLINE) {
    options = {
        endpoint: 'http://localhost:8000',
        region: 'localhost'
    }
}

const dynamodb = new DynamoDB.DocumentClient(options);

after that I run serverless dynamodb start --stage local in one shell and sls offline --stage local in the other one

This works, it's the first solution that worked for me, I will try to improve it in the meantime you could use this one

I've had some issue similar to this that were fixed by setting the correct order of plugins in serverless.yml file. Put serverless-offline before dynamodb, i.e. like below

plugins:
  - ...
  - serverless-offline
  - serverless-dynamodb-local

Yeah, same issue here... you can start it with sls dynamodb start but really needs to auto start with serverless-offline.

Edit: it seems I have found the solution... run serverless offline with the command: serverless offline start

According to the docs serverless-offline should be last https://github.com/dherault/serverless-offline#usage-with-serverless-dynamodb-local-and-serverless-webpack-plugin

# ✅ works
sls offline start
serverless offline start

# ❌ not work
sls offline
serverless offline

sls offline and serverless offline dose not start dynamodb-local automatically. But sls offline start and serverless offline start dose start dynamodb-local automatically.

Because serverless-dynamodb-local has hook with before:offline:start.

So you need to add start.
