The StakeHolderMap (SHM) uses a headless CMS approach, utilizing Python 3.6 and Flask.
For the Frontend TypeScript and ReactJs are used.
There are 4 different Docker Containers:

python-uwsgi
The flask application bundled with a uWSGI server as middleware to allow communication between flask and Nginx.
The uWSGI server is available on port 8080 (but unable to comprehend http requests with its current setup)

python-nginx
The Nginx server which handles requests from the frontend and passes them to the uWSGI server.
The Nginx server is available via localhost:8081 and should respond with alive, the health check.

tyepscript-nginx
The Nginx server which handles requests from the outside world.
The Nginx server is available via localhost:8082 and should respond with the ReactJS demo page.

adminer Database management webtool. Open localhost:8080 to connect to database. Use credentials from database.conf

postgres
The PostgreSQL database is available via port 5432.

The Dockerfiles are set up to avoid having build dependencies / files in the final docker image.

The project uses docker-compose for the local stack. Relevant commands:

docker-compose build  
docker-compose up -d  
docker-compose stop

To keep dependencies between python applications clean, it is recommended to use python virtual environments. To install virtualenv, run the following command:

sudo pip3 install virtualenv

sudo is required so the flask binary is available system-wide. Installing in user-space requires you to add the binary manually to your path. virtualenv might also be available as a package provided by your linux distribution.
Once virtualenv is installed, head to ./app-backend. Inside execute the following commands:

virtualenv venv  
source venv/bin/activate

This will activate the virtual environment and set PATHs appropriately for the current terminal session. To deactivate use the command deactivate.
Once the virtual environment is activated, you can start installing dependencies via pip3. To get started, execute the following command:

pip3 install -r requirements.txt

This will install all existing dependencies for the project. When you add new dependencies update the requirements.txt with the following command:

pip3 freeze > requirements.txt

If you don't need the full stack for your development, you can use flask's development server. To start it, run the following shell script (with your virtual environment activated):

./debug_server.sh

The development server is available on 127.0.0.1:5000 by default.

To run all tests, simply use the provided shell script:

./test.sh

If you don't want to use the script make sure the environment variables for the database connection are available.

To keep an eye on our code test coverage, there is another shell script available:

./coverage.sh

Additionally, you can add the argument html to the script to open a html version of the coverage result in your browser, providing more in-depth feedback.

To setup your database enter the docker container python-uwsgi, change to the /shm directory and execute the command flask db upgrade.
If you need to create a new migration, use the command flask db migrate. For further documentation see https://flask-migrate.readthedocs.io/en/latest/
