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" }
