Lethe GraphQL Api

This is a GraphQL Api that is used with the Lethe React Native application.

Development:

Environment Variables

You must have the following environment variables set to run development containers.

• SL_DATABASE_URL='mongodb://mongo:27017/dev'
  • use whatever mongo server you like, this will be the local mongo container.
  • use the following command to connect to the mongo container
    • docker exec -it letheapi_mongo_1 mongo

Optional environment variables

• SL_APOLLO_ENGINE_API_KEY='your Apollo Engine API Key here'
• PORT=9999 (default port is 9999)

Build and run development environment

docker-compose up --detach --build

Feel free to drop the --build, but use it for a fresh start on the images.

Update dependencies

This command will update the dev environments dependancies.

docker-compose run --rm dev yarn install && yarn cache clean

Once development environment is up, you can find check it at the following URL's

• graphql playground will be available at http://develop.localhost/graphql
• traefik dashboard will be available at http://traefik.localhost/

  these sites will only route in Chrome

Test:

Run tests and watch

docker-compose run test yarn test:watch

Dependancies

If you need to add a dependency you will need to add it to the local host for tooling and to the container.

Local host

yarn add <dependancy>

Failing to install the dependancy on the host could cause local tooling to not work.

Container

docker-compose run dev yarn add <dependancy>

Installing the dependancy in the container is most important, failure to do so will cause the app to fail on use of a new dependancy

Production

Secrets

You will need the following secrets defined in your swarm

• apollo_api_key
• sl_database_url
• now_token
• port

Build image

docker build --label letheapi --tag letheapi_prod:0.0.4 --target prod .

Deploy stack to swarm

docker stack deploy --compose-file docker-compose.prod.yml lethe-prod
