GraphQL,

you're intuitive and flexible,

we'll be friends

I know beginnings,
I know endings too,
and life-in-death, and something else
I'd rather not recall just now.

First encounter

We met in an unbelievable year,
When the world's strength was at an ebb

I marvel at everything as if it were new.

Getting to know better

Query

Mutation

Subscription

Schema

type Poet {
  name: String!
  nationality: String!
  literatureMovement: String!
  poems: [Poem]
  bornIn: Int!
  diedIn: Int!
}

type Query {
  poets: [Poet]
}

Resolvers

const resolvers = {
  Query: {
    poets: () => {
      // Here would be the logic for getting all the poets
      // But this time we'll just return an object
      return [{
        name: 'Anna Akhmatova',
        nationality: 'Russian / Soviet',
        literatureMovement: 'Acmeism',
        poems: [/* Here would be the poems */],
        bornIn: 1889,
        diedIn: 1966
      }]
    }
  }
}

Forgive me that I ignored the sun

And that I lived in sorrow.

The crush
