Usage

import {
  GraphQLDateDirective,
  GraphQLNumberDirective,
  GraphQLCurrencyDirective,
  GraphQLLowerCaseDirective,
  GraphQLUpperCaseDirective,
  GraphQLCamelCaseDirective,
  GraphQLStartCaseDirective,
  GraphQLCapitalizeDirective,
  GraphQLKebabCaseDirective,
  GraphQLTrimDirective,
  GraphQLDefaultToDirective,
  GraphQLToLowerDirective,
  GraphQLToUpperDirective,
  GraphQLTemplateDirective,
  GraphQLPhoneDirective,
  applySchemaCustomDirectives,
} from 'graphql-custom-directives';

const query = new GraphQLObjectType({
   name: 'Query',
   fields: {
     input: {
       type: GraphQLString,
       args: {
         value: {
           type: GraphQLString
         }
       },
       resolve: (source, {value}) => value
     }
   }
});

const schema = new GraphQLSchema({
  directives: [
    GraphQLDateDirective,
    GraphQLNumberDirective,
    GraphQLCurrencyDirective,
    GraphQLLowerCaseDirective,
    GraphQLUpperCaseDirective,
    GraphQLCamelCaseDirective,
    GraphQLStartCaseDirective,
    GraphQLCapitalizeDirective,
    GraphQLKebabCaseDirective,
    GraphQLTrimDirective,
    GraphQLDefaultToDirective,
    GraphQLToLowerDirective,
    GraphQLToUpperDirective,
    GraphQLPhoneDirective,
    GraphQLTemplateDirective
  ],
  query
});

applySchemaCustomDirectives(schema);

graphql(schema, `{ input(value: "test") @upperCase }`)
  .then(({ result, errors }) => {
     console.log(result); // will print { input: "TEST }
  });

Using with apollo

is also possible

import { makeExecutableSchema } from 'graphql-tools';
import {
  GraphQLDateDirective,
  GraphQLNumberDirective,
  GraphQLCurrencyDirective,
  GraphQLLowerCaseDirective,
  GraphQLUpperCaseDirective,
  GraphQLCamelCaseDirective,
  GraphQLStartCaseDirective,
  GraphQLCapitalizeDirective,
  GraphQLKebabCaseDirective,
  GraphQLTrimDirective,
  GraphQLDefaultToDirective,
  GraphQLToLowerDirective,
  GraphQLToUpperDirective,
  GraphQLTemplateDirective,
  GraphQLPhoneDirective
  applySchemaCustomDirectives
} from 'graphql-custom-directives';

let directives = [
    GraphQLDateDirective,
    GraphQLNumberDirective,
    GraphQLCurrencyDirective,
    GraphQLLowerCaseDirective,
    GraphQLUpperCaseDirective,
    GraphQLCamelCaseDirective,
    GraphQLStartCaseDirective,
    GraphQLCapitalizeDirective,
    GraphQLKebabCaseDirective,
    GraphQLTrimDirective,
    GraphQLDefaultToDirective,
    GraphQLToLowerDirective,
    GraphQLToUpperDirective,
    GraphQLTemplateDirective,
    GraphQLPhoneDirective
  ]

let schema = makeExecutableSchema(...);

schema._directives.push.apply(schema._directives, directives);
applySchemaCustomDirectives(schema);

Date formatting directives

Adding date directive to graphql query for formatting the result using Moment.

Using default date format:

  query {
    input(value: "2016-01-01T00:00:00") @date
  }
  // => { input: "01 Jan 2016 00:00" }

Using specific moment format:

  query {
    input(value: "2016-01-01T00:00:00") @date(as:"YYYY")
  }
// => { input: "2016" }

Using days ago format

  query {
    input(value: "${(new Date).toISOString()}") @date(as:"days ago")
  }
  // => { input: "0 days ago" }

Number formatting directives

Adding number directive to graphql query for formatting the result using Numeral-js.

Using default format:

  query {
    input(value: "1500.404") @number
  }
  // => { input: "1,500" }

Using specific numeral format:

  query {
    input(value: "-1500.404") @number(as:"(0,0.00)")
  }
  // => { input: "(1,500.40)" }

Using default currency format:

  query {
    input(value: "1500") @currency
  }
  // => { input: "$1,500)" }

String formatting directives

Adding string directive to graphql query for formatting the result using Lodash.

Using lowerCase directive:

  query {
    input(value: "FOO BAR") @lowerCase
  }
  // => { input: "foo bar" }

Using upperCase directive:

  query {
    input(value: "foo bar") @upperCase
  }
  // => { input: "FOO BAR" }

Using camelCase directive:

  query {
    input(value: "foo bar") @camelCase
  }
  // => { input: "fooBar" }

Using startCase directive:

  query {
    input(value: "foo bar") @startCase
  }
  // => { input: "Foo Bar" }

Using capitalize directive:

  query {
    input(value: "foo bar") @capitalize
  }
  // => { input: "Foo var" }

Using kebabCase directive:

  query {
    input(value: "foo bar") @kebabCase
  }
  // => { input: "foo-bar" }

Using trim directive:

  query {
    input(value: "  foo bar  ") @trim
  }
  // => { input: "foo bar" }

Using default directive:

  query {
    input @default(to:"N/A")
  }
  // => { input: "N/A" }

Using toLower directive:

  query {
    input(value: "FOO BAR") @toLower
  }
  // => { input: "foo bar" }

Using toUpper directive:

  query {
    input(value: "foo bar") @toUpper
  }
  // => { input: "FOO BAR" }

Using template directive:

  query {
    input(value: "foo bar") @template(as:"${input} ${toUpper(input)}")
  }
  // => { input: "foo bar FOO BAR" }

Using template together with trim and toUpper directives:

  query {
    input(value: "  foo bar   ") @trim @template(as:"${input} ${input}") @toUpper
  }
  // => { input: "FOO BAR FOO BAR" }

Phone formatting directives

Adding phone directive to graphql query for formatting the result using libphonenumber-js.

Using default international format:

  query {
    input(value: "+12133734253") @phone
  }
  // => { input: "+1 213 373 4253" }

Using specific format:

  query {
    input(value: "+12133734253") @phone(as: "national")
  }
// => { input: "(213) 373-4253" }
  query {
    input(value: "+12133734253") @phone(as: "RFC3966")
  }
// => { input: "tel:+12133734253" } // URI format
