Amber Backend

This is the backend app of Project Amber, a task list app.

This is a basic Flask/SQLAlchemy app that takes care of syncing tasks between devices.

Configuration

The config file is a JSON file that is loaded from either ./config.json or /etc/amber.json, whichever is found first.

Example config:

{
    "database": "sqlite:///file.db", // SQLAlchemy database URI
    // see https://docs.sqlalchemy.org/en/13/core/engines.html#database-urls
    "allow_signup": false, // whether to allow /api/signup or not
    "loglevel": 0, // 0: errors, 1: warnings, 2: info
    "domain": "https://your.domain.tld" // full domain with HTTPS, needed for CORS
}

If there are environment variables AMBER_DATABASE / AMBER_ALLOW_SIGNUP / AMBER_LOGLEVEL / AMBER_DOMAIN set, the program will respect them and use over the values provided with the config file.

Dependencies

This app directly depends on flask, flask-sqlalchemy, flask-cors, and bcrypt.

requirements.txt is left only so that pipenv is not needed while building the app in Docker. Please use pipenv in development.

Running in Docker

The Dockerfile included with the project assumes that:

1. You’re going to use either PostgreSQL or SQLite.
2. You’re going to run it behind a reverse proxy such as nginx (and running the app without a reverse proxy won’t work because of the current uwsgi configuration).

If you have to/prefer to use MariaDB, etc, you’ll have to add the necessary Python packages to the Docker image by hand. See SQLAlchemy docs for details.
