This is the code of the symptum application.

Symptum is an app that helps doctors make their differential diagnosis and allows the pharma industry to directly advertise new drugs.

We use docker to guarantee the same environment across all developers. Thus no one uses different library versions across machines, including system libraries.

Furthermore we use crane to orchestrate running our docker images with the same configuration across systems.

To use this project environment you need to install docker and crane.

https://docs.docker.com/engine/installation/#supported-platforms

For ubuntu you can go directly to: https://docs.docker.com/engine/installation/linux/ubuntu/

Also follow the post install steps for the docker user and auto start of docker https://docs.docker.com/engine/installation/linux/linux-postinstall/

Then install crane. See: https://github.com/michaelsauter/crane

As the npm packages are not commited to the git repository and docker images are mounted to the filesystem for development, you have to install the packages.

From the project root directory run:

cd frontend && crane run frontend npm install
cd ..
cd backend && crane run backend npm install

Note this step is only necessariy when we mount our local source code into the docker container during development. When running the docker container without mounting the local files, it will use the dependencies installed in the docker image. The crane configuration keyword for this is volume.

To guarantee a consistent coding style, please add the linter to the projects git hooks:

cp backend/misc/git/pre-commit .git/hooks/pre-commit

The crane.yml contains the orchestration configuration for the project.

To start the backend use:

crane run backend

It will automatically start the required postgres database and persist data to the persistence/ subfolder.

To start the frontend use:

crane run frontend

To connect both applications, you also need to run nginx:

crane run nginx

Special production configuration is provided. The app can be deployed by using:

crane run production-nginx

This will start postgres, production-backend,production-frontend and pgadmin.

For updating production make sure to pull the new docker image and stop/remove the container that needs to be updated. Then restart nginx.

Example:

crane pull production-frontend
crane rm --force production frontend
crane run production-nginx
