Original GitHub issue: https://github.com/atulmy/gql-query-builder/issues/94

I wish, I could define a query with variables, where some variables have the default value set

Original Example

✅ works well. I love it.

import * as gql from 'gql-query-builder'

const query = gql.query({
  operation: 'userLogin',
  variables: {
    email: { value: 'jon.doe@example.com', required: true },
    password: { value: '123456', required: true }
  },
  fields: ['userId', 'token']
})

console.log(query)

// Output
query ($email: String!, $password: String!) {
  userLogin (email: $email, password: $password) {
    userId, token
  }
}

// Variables
{
  email: "jon.doe@example.com",
  password: "123456"
}

Mine Proposal

❌ not available at the moment

import * as gql from 'gql-query-builder'

const { query, variables } = gql.query({
  operation: 'userLogin',
  variables: {
-    email: { value: 'jon.doe@example.com', required: true },
+    email: { value: 'jon.doe@example.com', required: true, backup: 'barry.smith@example.com' },
-    password: { value: '123456', required: true }
+    password: { value: '123456', required: true, backup: 'oneTwo' }
  },
  fields: ['userId', 'token']
})

console.log({ query, variables });

// Output
-query ($email: String!, $password: String!) {
+query ($email: String! = "barry.smith@example.com", $password: String! = "oneTwo") {
  userLogin (email: $email, password: $password) {
    userId, token
  }
}

// Variables
{
  email: "jon.doe@example.com",
  password: "123456"
}

Sometimes I wish I could include the variable values into default variable declaration, and not to have variables at all.
