So, since my happy little sst app is a skills exposition project, I'm considering writing one of my microservices in Python (The rest is in Typescript). My project uses the monorepo with Lerna, blah, blah template. I've already experimented briefly with

npx create-serverless-stack@latest [project name] --language python

. Some thoughts on this: • The above creates a hybrid of Javascript sst code, Javascript sst tests for

MyStack.js

, and Python for the lambdas. The usual package.json, etc. • Where/how are the Python dependencies needed in my Lambdas managed (since I'm seeing node stuff everywhere else)? • What happens when I run

npx sst test

? I know Jest is a part of serverless stack, so what happens with whatever Python testing framework I'll end up using (for domain object unit tests)? Does the test command detect that and respond accordingly, or do I have to wire that up? Or, do I just run a separate command to run the Python tests? • My guess is that sst knows how to bundle and deploy Python Lambdas by detecting the

.py

extension. • Integration tests can still still be in typescript, since that's what they are for my typescript microservices and don't intrude into the guts of my Lambdas.

Hey @Luke Wyman, for Python, you can use plain

requirements.txt

, PipFile or Poetry to manage the dependencies. Just point

srcPath

to where

requirements.txt

or

Pipfile

or

poetry.lock

is.

That's awesome, @Frank! Will definitely be following that effort. Which of of

requirements.txt

,

Pipfile

, or

poetry.lock

would you guess is the most popular/progressive, and compatible with my sst effort? Same question for the a unit testing library for Python.

They should all work well out of the box. On

sst deploy

, if you have

Pipfile

or

poetry.lock

, they simply get converted to

requirements.txt

, and the steps after that are exactly the same.

Thanks 🙂
