npm test

Or

npm run test:watch

Docker and docker-compose

No needs for installing dependencies or running mongod in another terminal window

docker-compose build && docker-compose up

Test

docker-compose -f docker-compose.test.yml build && docker-compose -f docker-compose.test.yml up

Production

# first compile the code
npm run build

# run graphql compiled server
npm start

Flow

npm run flow

Or

flow
