Flaredown makes it easy for people to track symptoms over time, and learn how to control them. Our goal is to analyze the aggregate data from users of this tool to understand the probable effects of treatments and environmental stressors on chronic illness.

Help would be appreciated! Please join us in slack #flaredown, raise a GitHub issue, or email contact@flaredown.

Environment

PostgreSQL 12.8
MongoDB 4.4.9
Redis 6.2.3
Ruby 3.2.3
Node 12.22.6

Installation

You can run the application and its dependencies using docker compose, or run the app natively using the setup instructions below. Alternatively, you can run the app using the make commands available: make help

If you want to run the application on your own machine see the next sections on dependency installations.

Running with Docker

Populate the necessary environment parameters:

cp backend/env-example backend/.env
cp frontend/env-example frontend/.env

In frontend/.env, PORT is the backend API port used by the Ember app and FRONTEND_PORT is the local frontend port.

Set FACEBOOK_APP_ID in frontend/.env if you want to use Facebook login locally.

Set up the database:

docker compose --profile tools run --rm app-setup

This command is interactive and resets the local Docker development and test databases. Type yes when prompted to continue.

Start the application:

docker compose --profile dev up

Visit your app at http://localhost:4300.

Frontend dependency changes are handled automatically by Docker. For a full reset of all local Docker data, including databases and dependency volumes, run docker compose down -v, then run the database setup command again afterward.

Running natively

Mac Prerequisites

If you are running on an M1 mac, run the following command before you start the installation process:

$env /usr/bin/arch -arm64 /bin/zsh ---login

Remove all gems before you proceed

gem uninstall -aIx

Backend

You can install the dependencies via asdf-vm declared in the .tool-versions file, or:

On macOS, you can install libpq by running brew install libpq && brew link --force libpq && bundle config --local build.pg "--with-ldflags=-L$(brew --prefix libpq)/lib --with-pg-include=$(brew --prefix libpq)/include", which is required for bundle install to succeed.

cd backend
echo "gem: --no-ri --no-rdoc" > ~/.gemrc
bundle config set --local without 'production'
bundle config set --local jobs 5
bundle config set --local retry 10
bundle install
cp env-example .env # You may adjust it however you like
                    # RVM is going to autoload this on every 'cd' to the directory
bundle exec rake app:setup

gem install foreman

Frontend

cd frontend
npm install

React Native

cd native
npm install

Development

Prerequisites

Populate the necessary environment parameters with cp backend/env-example backend/.env && cp frontend/env-example frontend/.env
Create a Facebook dev app and paste your own ID into frontend/.env file's FACEBOOK_APP_ID parameter.
- Note: This is not necessary in backend/.env but we have not yet cleaned up these two files into the necessary components.
Reset, migrate, load fixtures, and seed your database using make seed or bundle exec rails app:setup

Running

If you are running the application natively, run the following to start your server. If you're using docker, this should be up and running already.

rake run

Visit your app at http://localhost:4300 for the current ember application, or http://localhost:19006 for the React Native version.

Running tests locally

Run make build or docker compose build backend to ensure the latest backend is built and being run
To run all tests run make specs or script/backend rspec spec spec, or you can run a specific test suite such as script/backend rspec spec spec/services/weather_retriever_spec.rb
Debugging tip: in Ruby code you can add a line that says debugger and rspec will automatically break on that line and give you an interactive Ruby shell

CI

Several checks are configured to run on all commits using GitHub Actions, including lint, build and test steps. Definitions can be found in ./.github/workflows. Those checks which always run are required to be successful for pull requests to be merged.

Deployment

Deployments target Heroku. The traditional deployment is manually configured and is composed of two distinct applications (frontend and api) in two environments (staging and production), with automatic deployments to staging of commits to master:

Addons are used for Heroku Postgres, Heroku Redis, Heroku Scheduler + Papertrail. MongoDB is provided by mongodb.com.

Common Problems

On first load, the app displays a blank beige screen instead of the login screen. Temporary fix is to add console.log(process.env.FACEBOOK_APP_ID) right inside of the module.exports at the top of the frontend/config/environment.js file. You can then refresh the page (no need to kill Docker) and this should fix it. You can now remove the log.
