Development

Before you start contributing read the Contributing Guide!

Bootstrap

Create your local .env file

cp .env.sample .env

Install Packages

yarn

Initial TS Compilation For Monorepo Packages

yarn typecheck

Adding a package to the codebase can be done with Lerna

Run services

Start backend services

yarn docker:start

For M1 Mac Users

Official docker images of Hasura don't work on M1 yet

In hasura/Dockerfile Replace

FROM hasura/graphql-engine:v1.3.3.cli-migrations-v2

with

FROM fedormelexin/graphql-engine-arm64:v1.3.3.cli-migrations-v2

• Runs docker containers for backend, Hasura Engine, and PostGres database
• will auto-restart on any changes to packages/backend and packages/utils

If you are running for the first time on an empty database, once the services are running you have two options to populate the database:

1. Populate the database with the production dataset:

yarn hasura:seed-local-db

2. Populate the database with the initial dataset:

curl -X POST http://localhost:4000/actions/migrateSourceCredAccounts?force=true

Rebuild backend services

If your docker containers fail to start due to changes in config, you may need to rebuild the containers. This can take several minutes.

yarn docker:build

Stop backend services

yarn docker:stop

• Stops all the containers

If you want to locally start the backend server (not in Docker) for debugging purposes:

yarn backend:dev

Troubleshooting

Rebuild and run the containers (in attach mode):

docker-compose up --build

In case non of the above commands are working try purge the docker containers and images you can do this by running (notice: this removes all the containers and images on your computer!):

docker system prune -a

Run NextJS Web App dev mode (new)

yarn web:dev

Go to http://localhost:3000

Happy Coding!

Run Discord Bot

yarn discord-bot dev

Tooling

Start Hasura console

yarn hasura:console

Hasura CLI example

yarn hasura migrate status
yarn hasura migrate squash --name "<feature-name>" --from 1598417879553
yarn hasura migrate apply --version "<squash-migration-version>" --skip-execution

Hasura CLI documentation Hasura Migrations Guide

Generate GraphQL Types

yarn generate

Reload Schema + Generate GraphQL Types (backend needs to be running)

yarn update-schema
yarn generate

Restart with fresh database

yarn docker:clean
yarn docker:start

Run typechecks

yarn typecheck

WIP Branch Push

Upon pushing to the repository a linting check will be initialized validating your code. If you want to push the branch to the repository (maybe for collaboration) while the code isn't completely valid yet you have the option of skipping the linting process:

git push -u origin <branch> [--no-verify]

Please use this only when absolutely necessary!
