Github CI

This repository provides the source code of the new HHub API, which powers Homebrew Hub, the largest digital collection of Game Boy and Game Boy Color homebrews, playable natively in your browser.

API Documentation

Documentation about the exposed API and how to interact with the Homebrew Hub instance over hh3.gbdev.io, see API.md.

Local Development

To run a complete local instance of Homebrew Hub, let's start with:

# Cloning the repo locally
git clone https://github.com/gbdev/homebrewhub

# Changing directory into the cloned repo
cd homebrewhub

1. Prerequisites

No matter if you choose the local setup or the docker one, you will need a couple of pre-requirements on the system:

  • The executable pre-commit, available as a pip package. E.g.: 
    python3 -m venv env
sourc env/bin/activate
pip install pre-commit
    After it's installed, run pre-commit install in the project root folder to see if everything gets initialised correctly.
  • (Optional) The gbtoolsid (Game Boy Toolchain ID) executable must be available in the project root to populate toolchain details for the imported entries. Get a build on the Releases page and extract the zip.

2. Pull the games database(s)

# Clone the database repositories
# GB/GBC
git clone https://github.com/gbdev/database/
# GBA
git clone https://github.com/gbadev-org/games database-gba

3A. Docker based requirements

First, install Docker (download link).

After that, follow the steps below to get started running the project using containers:

# Start up backing services (web server, database and database admin)
# NOTE: This command will also take care of synchronising the database (including migrations)
docker-compose up --build

# Once that's finished, in another terminal, query the /api/all route to see if everything's there
curl https://localhost:8000/api/all

3B. Manual requirements

You need Python 3 and a couple of packages to build psycopg2 (database driver).

On Linux, this command should install all requirements:

apt install python3 libpq-dev python3-dev python3-venv

Next, install Postgres 12 (download link), create a user, password and a database named hh. Have it running in the background on port 5432.

After that, follow the steps below to get started running the project manually:

# Clone the repo locally
git clone https://github.com/gbdev/homebrewhub

# Change into the cloned repo
cd homebrewhub

# Set up a virtual env
python3 -m venv env

# Activate it
source env/bin/activate

# Install Python dependencies
pip install -r requirements.txt

# Install Pre-Commit git hooks (for enforcing code style on git commit)
pre-commit install

# Prepare migrations for our Entry model
python3 manage.py makemigrations hhub

# Sync the database for the first time
python3 manage.py migrate

# Clone the database repositories
# GB/GBC
git clone https://github.com/gbdev/database/
# GBA
git clone https://github.com/gbadev-org/games database-gba

# Populate with the entries from the database repository
DATABASE_URL=postgres://yourpostgresuserhere:yourpostgrespasswordhere@localhost:5432/hh python3 manage.py runscript sync_db

# Optional note: You can export the environment variable to avoid typing it each time:
EXPORT DATABASE_URL=postgres://yourpostgresuserhere:yourpostgrespasswordhere@localhost:5432/hh

# Start the Django app
DATABASE_URL=postgres://yourpostgresuserhere:yourpostgrespasswordhere@localhost:5432/hh python3 manage.py runserver

# In another terminal, query the /api/all route to see if everything's there
curl https://localhost:8000/api/all

4. Synchronising the database

The Homebrew Hub "source" database is simply a collection of folders, hosted as a git repository, each one containing an homebrew entry (ROM, screenshots, ..) and a "game.json" manifest file providing more details and metadata in a consistent way (see the game.json JSON schema).

For more information check the "database" repository documentation.

This enables the database to be "community-maintained", allowing everyone to add new entries (manually or by writing scrapers) or improve existing ones simply by opening Pull Requests.

The "real" database needs to be built (and updated when a commit gets pushed) from this collection of folders. This job is done by the sync_db.py script.

Keep in mind that the two are not equivalent, as the Django database will keep additional values about each entry (e.g. simple analytics).

python3 manage.py runscript sync_db

5. Get the frontend running

Now that you have your Homebrew Hub backend up and running, you can check Virens, our Vue-powered Homebrew Hub frontend shipping web assembly builds of mGBA and binjgb to actually play all these entries directly on a browser :D
