@mattwr18 I prefer (I believe it's even best practice) that a delete
mutation should return the deleted object. If you run the delete
mutation again, it should return `null` because there is no object like
that anymore. That way the client knows if a delete mutation has changed
any state in the database.
Also I fixed another bug in the resolver. If your graphql mutation looks
like this:
```gql
mutation {
RemovePostEmotions(to:{ id:"p15"}, data:{emotion: angry}) {
from {
id
name
}
to {
id
title
}
emotion
}
}
```
Then you get errors because your resolver does not return the name for
the user or the title for the post anymore. Just use spread operator...
and it's fixed.
Backend
Installation with Docker
Run the following command to install everything through docker.
The installation takes a bit longer on the first pass or on rebuild ...
$ docker-compose up
# rebuild the containers for a cleanup
$ docker-compose up --build
Wait a little until your backend is up and running at http://localhost:4000/.
Installation without Docker
For the local installation you need a recent version of node
(>= v10.12.0).
Install node dependencies with yarn:
$ cd backend
$ yarn install
Copy Environment Variables:
# in backend/
$ cp .env.template .env
Configure the new file according to your needs and your local setup. Make sure a local Neo4J instance is up and running.
Start the backend for development with:
$ yarn run dev
or start the backend in production environment with:
yarn run start
For e-mail delivery, please configure at least SMTP_HOST and SMTP_PORT in
your .env configuration file.
Your backend is up and running at http://localhost:4000/
This will start the GraphQL service by default on localhost:4000 where you
can issue GraphQL requests or access GraphQL Playground in the browser.
Seed Database
If you want your backend to return anything else than an empty response, you need to seed your database:
{% tabs %} {% tab title="Docker" %}
In another terminal run:
$ docker-compose exec backend yarn run db:seed
To reset the database run:
$ docker-compose exec backend yarn run db:reset
# you could also wipe out your neo4j database and delete all volumes with:
$ docker-compose down -v
{% endtab %}
{% tab title="Without Docker" %} Run:
$ yarn run db:seed
To reset the database run:
$ yarn run db:reset
{% endtab %} {% endtabs %}
Testing
Beware: We have no multiple database setup at the moment. We clean the database after each test, running the tests will wipe out all your data!
{% tabs %} {% tab title="Docker" %}
Run the jest tests:
$ docker-compose exec backend yarn run test:jest
Run the cucumber features:
$ docker-compose exec backend yarn run test:cucumber
{% endtab %}
{% tab title="Without Docker" %}
Run the jest tests:
$ yarn run test:jest
Run the cucumber features:
$ yarn run test:cucumber
{% endtab %} {% endtabs %}
