EDH-Go

A Magic: The Gathering board state tracker built with GraphQL and Go.

Running

Go Server

1. Prerequisites:

• Make
• Go v1.15

1. Set Environment variables Here's a template for setting the appropriate env vars in ~/.bashrc

export DEFAULT_PORT=
export REDIS_URL=
export DATABASE_URL=
export LOG_LEVEL=
export JWT_SECRET=

Then run the server with our Makefile. The server will attempt to run all migrations and then start up. If it can't run migrations, it will rollback the database and noisily fail.

$ make run 

You can run the server as if it's in prod with this same config, so you can switch between local and prod as long as you've configured your environment variables correctly.

Front End

Run Vue app:

$ cd frontend
$ yarn start

Testing

Prerequisites

• Postgres instance running locally localhost@5432
• Redis instance running at localhost:6379

To run the API tests

$ make test-api

Once you have a Redis and Postgres instance running locally, you can run your tests. You may need to change the config values in games_test.go to start your tests or configure your environment to fit with the provided

Stack

Postgres for the application data SQLite is used for querying card data. Redis is used for fast and efficient storing of BoardStates and Games. Using an SQL based storage solution for the BoardStates would have been clunky.

Deployment

Front end

Deployment of the front end is triggered by updates pushed to mvp right now. However, we need to find a better way to detect the front end changes.

Prerequisites

• node@v15
• yarn
• vue-cli
• Heroku toolbelt
• Heroku static buildpack (see https://gist.github.com/hone/24b06869b4c1eca701f9)

Follow this guide for how we deploy front end updates. https://gist.github.com/hone/24b06869b4c1eca701f9

Official Heroku documentation for the static buildpack https://github.com/heroku/heroku-buildpack-static

heroku static:deploy will deploy the vue app to heroku. You can also run npm run deploy and this will run the same thing.

Server

• Heroku will build and deploy any push to GitHub.
• Environment variables are handled in Heroku.
