How to use

Main usage of graphql zeus should be as a CLI.

As a CLI

Installation

Install globally

$ npm i -g graphql-zeus

Of course you can install locally to a project and then use as a npm command or with npx

Usage with JavaScript

$ zeus schema.graphql ./

It will also generate corresponding out.d.ts file so you can have autocompletion,

Usage with TypeScript

$ zeus schema.graphql ./  --ts

Usage with NodeJS

$ zeus schema.graphql ./  --node

Usage with React Native

Same as browser

$ zeus schema.graphql ./

Load from URL

$ zeus https://faker.graphqleditor.com/a-team/olympus/graphql ./generated

With Authorization header

$ zeus https://faker.graphqleditor.com/a-team/olympus/graphql ./generated --header=Authorization:dsadasdASsad

Use generated client example

$ zeus https://faker.graphqleditor.com/a-team/olympus/graphql ./generated

Perform query with Chain

import { Chain } from './graphql-zeus';
const createCards = async () => {
  const chain = Chain('https://faker.graphqleditor.com/a-team/olympus/graphql');
  const listCardsAndDraw = await chain.query({
    cardById: [
      {
        cardId: 'sdsd'
      },
      {
        description: true
      }
    ],
    listCards: {
      name: true,
      skills: true,
      attack: [
        { cardID: ['s', 'sd'] },
        {
          name: true
        }
      ]
    },
    drawCard: {
      name: true,
      skills: true,
      Attack: true
    }
  });
};
createCards();
// Result of a query
// {
//     "drawCard": {
//         "Attack": 83920,
//         "name": "Raphaelle",
//         "skills": [
//             "RAIN",
//             "THUNDER",
//         ]
//     },
//     "cardById": {
//         "description": "Customer"
//     },
//     "listCards": [
//         {
//             "name": "Lon",
//             "skills": [
//                 "THUNDER"
//             ],
//             "attack": [
//                 {
//                     "name": "Christop"
//                 },
//                 {
//                     "name": "Theodore"
//                 },
//                 {
//                     "name": "Marcelle"
//                 }
//             ]
//         },
//         {
//             "name": "Etha",
//             "skills": null,
//             "attack": [
               
//                 {
//                     "name": "Naomie"
//                 }
//             ]
//         },
//         {
//             "attack": [
//                 {
//                     "name": "Kyle"
//                 },
//             ],
//             "name": "Arlene",

//             ]
//         }
//     ]
// }

Perform query with Thunder - Abstracted Fetch function

With thunder you have total control of fetch function not losing the result format the same time.

import { Thunder } from './graphql-zeus';
const createCards = async () => {
  const thunder = Thunder(async (query) => {
    const response = await fetch('https://faker.graphqleditor.com/a-team/olympus/graphql', {
      body: JSON.stringify({ query }),
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
    });
    if (!response.ok) {
      return new Promise((resolve, reject) => {
        response
          .text()
          .then((text) => {
            try {
              reject(JSON.parse(text));
            } catch (err) {
              reject(text);
            }
          })
          .catch(reject);
      });
    }
    const json = await response.json();
    return json;
  });
  const listCardsAndDraw = await thunder.query({
    cardById: [
      {
        cardId: 'sdsd'
      },
      {
        description: true
      }
    ],
    listCards: {
      name: true,
      skills: true,
      attack: [
        { cardID: ['s', 'sd'] },
        {
          name: true
        }
      ]
    },
    drawCard: {
      name: true,
      skills: true,
      Attack: true
    }
  });
};
createCards();
// Result of a query
// {
//     "drawCard": {
//         "Attack": 83920,
//         "name": "Raphaelle",
//         "skills": [
//             "RAIN",
//             "THUNDER",
//         ]
//     },
//     "cardById": {
//         "description": "Customer"
//     },
//     "listCards": [
//         {
//             "name": "Lon",
//             "skills": [
//                 "THUNDER"
//             ],
//             "attack": [
//                 {
//                     "name": "Christop"
//                 },
//                 {
//                     "name": "Theodore"
//                 },
//                 {
//                     "name": "Marcelle"
//                 }
//             ]
//         },
//         {
//             "name": "Etha",
//             "skills": null,
//             "attack": [
               
//                 {
//                     "name": "Naomie"
//                 }
//             ]
//         },
//         {
//             "attack": [
//                 {
//                     "name": "Kyle"
//                 },
//             ],
//             "name": "Arlene",
//             "skills": [
//                 "FIRE",
//             ]
//         }
//     ]
// }

Unions

You can use Zeus with unions:

const { drawChangeCard } = await chain.query({
    drawChangeCard: {
      __typename: true,
      '...on EffectCard': {
        effectSize: true,
        name: true
      },
      '...on SpecialCard': {
        effect: true,
        name: true
      }
    }
});
// drawChangeCard result:
// {
//     "effectSize": 195.99532210956377,
//     "name": "Destinee",
//     "__typename": "EffectCard"
// }

Interfaces

And interfaces.

const {nameables} = await Gql.query({
    nameables: {
      "__typename": true,
      "name": true,
      "...on CardStack": {
        cards: {
          Defense: true,
        },
      },
      "...on Card": {
        Attack: true,
      },
    },
  });
// result
// {
//     "nameables": [
//         {
//             "__typename": "EffectCard",
//             "name": "Hector"
//         },
//         {
//             "__typename": "CardStack",
//             "name": "Scotty",
//             "cards": [
//                 {
//                     "Defense": 1950
//                 },
//                 {
//                     "Defense": 76566
//                 },
//                 {
//                     "Defense": 64261
//                 }
//             ]
//         },
//         {
//             "__typename": "SpecialCard",
//             "name": "Itzel"
//         },
//     ]
// }

Perform query with aliases

const aliasedQueryExecute = await chain.query({
    listCards: {
      __alias: {
        atak: {
          attack: [
            { cardID: ["1"] },
            {
              name: true,
              description: true,
            },
          ],
        },
      },
    },
  });
// RESULT
// {
//     "listCards": [
//         {
//             "atak": {
//                 "attack": [
//                     {
//                         "name": "Zelma",
//                         "description": "Central"
//                     }
//                 ]
//             }
//         }
//     ]
// }

So you can access properties type-safe like this

aliasedQueryExecute.listCards.map(c=>c.atak.attack)

Variables

To perform query with variables please import $ function and pass the variables to query

  const test = await Gql.mutation(
    {
      addCard: [
        {
          card: $`card`,
        },
        {
          id: true,
          description: true,
          name: true,
          Attack: true,
          skills: true,
          Children: true,
          Defense: true,
          cardImage: {
            bucket: true,
            region: true,
            key: true,
          },
        },
      ],
    },
    {
      card: {
        Attack: 2,
        Defense: 3,
        description: 'Lord of the mountains',
        name: 'Golrog',
      },
    },
  );

Gql string

Use Zeus to generate gql string

import { Zeus } from './graphql-zeus';
const createCards = async () => {
  const stringGql = Zeus.query({
    listCards: {
      name: true,
      skills: true,
      Attack: true
    }
  });
  // query{listCards{name skills Attack}}
};
createCards();

To run the example navigate to: ./example and run

$ npm i

then run

$ npm run start

Use Api for single queries mutations and Chain for query chaining

JavaScript Type Casting

You can cast your response from fetch/apollo/other-lib to correct type even if you are using JavaScript:

import { Cast } from './graphql-zeus';
const myQuery = Cast.query(myLib("somegraphqlendpoint"))

Typescript SelectionSet

In TypeScript you can make type-safe selection sets to reuse them across queries You can use Selectors on operations or ZeusSelect on concrete type. Only Selectors make sense in JS as usage of ZeusSelect on type is impossible without type support :)

import { ZeusSelect, Selectors, Chain, ValueTypes } from './graphql-zeus';
const chain = Chain('https://faker.graphqleditor.com/a-team/olympus/graphql');

const { drawCard: cardSelector } = Selectors.query({
  drawCard: {
    name: true,
    description: true,
    Attack: true,
    skills: true,
    Defense: true,
    cardImage: {
      key: true,
      bucket: true
    }
  }
});

const cardSelector2 = ZeusSelect<ValueTypes["Card"]>()({
  name: true,
  description: true,
  Attack: true,
  skills: true,
  Defense: true,
  cardImage: {
    key: true,
    bucket: true
  }
});

const queryWithSelectionSet = await chain.query({
  drawCard: cardSelector,
  listCards: cardSelector2,
});

Spec

Promise of type query data object is returned.

PROMISE_RETURNING_OBJECT = Chain.[OPERATION_NAME]({
    ...FUNCTION_FIELD_PARAMS
})(
    ...QUERY_OBJECT
).then ( RESPONSE_OBJECT => RESPONSE_OBJECT[OPERATION_FIELD] )

Simple function params object

FUNCTION_FIELD_PARAMS = {
  KEY: VALUE
}

Query object

QUERY_OBJECT = {
    ...RETURN_PARAMS
}

Return params is an object containg RETURN_KEY - true if it is a scalar, RETURN_PARAMS if type otherwise it is a function where you pass Fiel params and type return params.

RETURN_PARAMS = {
    RETURN_KEY: true,
    RETURN_KEY: {
        ...RETURN_PARAMS
    },
    RETURN_FUNCTION_KEY:[
        {
            ...FUNCTION_FIELD_PARAMS
        },
        {
            ...RETURN_PARAMS
        }
    ]
}

Use Alias Spec

RETURN_PARAMS = {
  __alias: RETURN_PARAMS
}

Access aliased operation type-safe

PROMISE_RETURNING_OBJECT[ALIAS_STRING][OPERATION_NAME]

Use In your Project to generate code

This will be rarely used, but here you are!

import { Parser,TreeToTS } from 'graphql-zeus';

const schemaFileContents = `
type Query{
    hello: String!
}
schema{
    query: Query
}
`

const typeScriptDefinition = TreeToTS.resolveTree(Parser.parse(schemaFileContents));

const jsDefinition = TreeToTS.javascript(Parser.parse(schemaFileContents));

Use in your project to dynamically fetch schema

This is useful when you need some schema fetched from your GraphQL endpoint

import { Utils } from 'graphql-zeus';

Utils.getFromUrl("https://faker.graphqleditor.com/a-team/olympus/graphql").then(schemaContent => {
  // Use schema content here
})
