Project Simplification using locally installed LocalStack for mock AWS

How LocalStack Works Locally (Without Docker)

You can install LocalStack directly on your machine without Docker by following these steps:

Step 1: Install LocalStack via pip LocalStack can be installed as a Python package via pip:

pip install localstack

Step 2: Start LocalStack Locally

Once installed, you can start LocalStack directly on your machine:

localstack start

This will run LocalStack and expose services like S3, DynamoDB, and Lambda on localhost:4566, which can be accessed by your locally running NestJS app.

Step 3: Update .env File

Update your NestJS environment to point to localhost:

AWS_ENDPOINT=http://localhost:4566

Now, the NestJS app running locally can directly connect to LocalStack at http://localhost:4566, avoiding any Docker-related networking issues.

Would This Have Prevented Issues?

• Yes, running both LocalStack and NestJS locally (without Docker) would have likely prevented the connection issues you encountered. By eliminating the complexity of Docker networking, you can reduce the number of variables that could cause problems.
• If you’d prefer to keep Docker for other parts of the project but still want to avoid issues with LocalStack, you could run LocalStack locally and NestJS in Docker. The NestJS app could still connect to LocalStack via http://host.docker.internal:4566 (which routes Docker containers to the host machine).

I had an English test last Monday and haven't had a chance to come back to this and any coding till today, Saturday, late morning.

That being said, I have been looking at the stacks of various jobs, especially the backend ones that I like and comparing it with the stack here and doing some thinking in terms of if:

• All is well with the stack and architecture, or some things need to change.
• My conclusion so far is that the stack is great and i should focus on completing an end-to-end MVP first with nest, next, GraphQL, etc

So, i gave up on the idea of running localstack with docker-container based nestjs or any other service since i can running to connection issues.. uninstall localstack and its deps from my machine. Might look into doing this with MinIO, OpenFaas etc toolset
