A ReactJS + Flask (REST API) + PostgreSQL boilerplate with Docker usage
This project allows to run a quick application with ReactJS (Javascript front-end), Flask (Python backend) and PostgreSQL (relational database) by running it on Docker containers.
A database named sport_stats (user: myuser / password: mypassword) is initialized when the database container start. These default values can be changed in the docker-compose.yml file.
A table players with one record is created by copying the file db/init/init.sql into the /docker-entrypoint-initdb.d/ container directory (see documentation of postgres official image).
The Flask application uses SQLAlchemy to retrieve the content of the players, ReactJS call the REST API and display it !
Hot reloading is enabled for the React and Flask code, after every code change the container is up-to-date automatically !
Everything is containerized from the client, backend to the database. So all you need is Docker installed, and then you can run :
docker-compose up --build
And your app will be up on the port 3000 !
This project was implemented with Docker Toolbox, which need some fixes (read my article on medium for more information) before running the docker-compose up command.
That's the goal of the docker-compose-up.sh file at the root of the project, use it instead of the docker-compose up command if you are running Docker with the Toolbox.
Flask and ReactJS part of the application use the IP adress / port for containers communication (see config.py and config.js). You can normally use the name of the service located on the docker-compose.yml, but it doesn't seems to work using Docker Toolbox !
If you change user, password, database name or any other kind of database configuration, you may need to run docker-compose -up --build from a fresh start. Make sure to run docker-compose down before or even docker-compose rm if some containers are stopped but not destroyed.
