Usage

# about a few minutes in order to build everything
docker-compose build

# to run interactively, to see logs realtime
docker-compose -f docker-compose.dev.yml up

# to enter shell on backend - you need to have working postgres database*
docker-compose -f docker-compose.dev.yml run backend /bin/sh

#run backend tests
docker-compose -f docker-compose.dev.yml run backend pytest --cov


## in order to start without front - you have to start it on your own by yarn.
docker-compose -f docker-compose.frontend.yml  up


#* 'docker-compose up -d' may be sufficent

Docker compose files and differences between them

In repo you can find three docker composes:

• docker-compose.frontend.yml with disabled frontend container - due to problems related with hot reload in recent version react-create-app.
• docker-compose.dev.yml which is designed to debug things
• docker-compose.prod.yml which will be optimized for production use.

How to's

How to add a new library in backend?

You need to have a poetry tool installed on your system and run poetry add <lib> in backend directory. Then rebuild the container - docker-compose build

Troubleshooting

Starting a docker container fails on Windows due to migrate\r

Wheter git thinks that automatic CRLF would be great on Windows - it isn't our case because we are mounting the backend directory as a volume to the apprioprate container. One of solution is running following set of commands in this repo:

git config core.eol lf
git config core.autocrlf input
git rm -rf --cached .
git reset --hard HEAD

This will force storing all files with LF file ending

Relay can't compile new queries

It might be related with schema out of date. There are steps to fix it:

1. Have a working database in the backround - docker-compose -f docker-compose.dev.yml up -d
2. Run docker-compose -f .\docker-compose.yml run backend python manage.py graphql_schema --schema schema.schema_v1 --out schema.graphql
3. Copy schema.graphql from backend folder to frontend
