drf_ddd_order_app

An example Order App in transient DDD style on django drf

Note

This is for demo only. DO NOT RUN IN PRODUCTION. USE AT YOUR OWN RISK. Django keys and hard coded secrets inside.

Motivation

How to use DDD in django drf. When you start out with a web application, it is easy to prototype using RAD tools like django & drf. Eventually, you get locked-in and there is little space to free your concerns to Plain-Old Python Objects.

Why do that? Here is a good article from Snapchat to understand why: https://eng.snap.com/en-US/monolith-to-multicloud-microservices-snap-service-mesh

You will see couple of libraries sprinkled here and there. That is to showcase what may you need in order to build this.

How to Test?

Just do this to register

curl --location --request POST 'https://drfdddorderapp-production.up.railway.app/register/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "username": "dkljhlksfrfasasddas",
    "password": "kldsjfsda"
}'

And this to login

curl --location --request POST 'https://drfdddorderapp-production.up.railway.app/auth/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "username": "dkljhlksfrfasasddas",
    "password": "kldsjfsda"
}'

In both cases you should get a jwt back.

Then you can use it to create an order. Which is the motivation for this app. But it is not done yet.

How to Run locally?

Build it like:

docker build . --progress=auto -t order_mgmt:demo -f Dockerfile

and run it like:

docker run -e "DEBUG=FALSE" -e "ALLOWED_ENV_URL=127.0.0.1" -p 8000:8000 order_mgmt:demo

But You have left password in plain text? This isn't there, that isn't there, this is missing,

Yes, See what this repo is about in the above description.

But but but!

I charge for these services. I am not a charity.
