Opportunity Hack Developer Portal (Backend)

• 📝 ohack.dev frontend code is here
• This code is the backend api.ohack.dev and supports ohack.dev frontend.
• Like most things we build, to keep it simple, this runs on Heroku.
• We borrowed the code from Auth0 here to bootstrap our development (always a good practice)
• If you plan on doing database work, see our guide to cloning our Firebase Firestore Database

Quickstart

• Use this doc to setup GitHub Codespaces: you won't need to download anything on your computer

• Install Python modules

pip install -r requirements.txt

• Run the app

flask run

• Create a .env file under the root project directory and populate it with the contents listed in our doc here

Running this on your laptop

The easy way with Heroku CLI

• Review these instructions
• Install Heroku CLI
• Run via heroku local command

The longer way

Create a virtual environment. You can use:

1. Miniconda (preferred)
2. Virtual Env (venv)
3. Anaconda
4. Don't create a virtual environment at all and trample on a single Python environment you might already have

What are the diffs between Miniconda and Anaconda? See this

You'll need to run Python 3.9.13 (see runtime.txt) to match the same version that Heroku runs.

Once you have a virtual environment ready, you will want to install the project dependencies:

pip install -r requirements.txt

Create a .env file under the root project directory and populate it with the following content:

You will need to get these values from our Slack channel.

Command Line

Run the project in development mode:

Interpreters

Set the interpreter via the command pallete Python: Select Interpreter (source)[https://code.visualstudio.com/docs/python/environments#_working-with-python-interpreters]

Getting Firestore Emulator Running

• Setting up a fully functional database in Firebase Emulator
• Get gCloud CLI since the Python code will rely on this to connect to FireStore

brew install java11
sudo ln -sfn /usr/local/opt/openjdk\@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.11.jdk
npm install -g firebase-tools
gcloud auth application-default login
