gql-payload

GraphQL Payload Builder

This is an optimized fork of gql-query-builder with extra features for generating GraphQL payloads using plain JavaScript Objects (JSON).

Install

npm install gql-payload --save or yarn add gql-payload

Usage

import { gqlQuery, gqlMutation, gqlSubscription } from 'gql-payload'

const query = gqlQuery(options: object)
const mutation = gqlMutation(options: object)
const subscription = gqlSubscription(options: object)

Options

options is { operation, fields, variables } or an array of options

Name	Description	Type	Required	Example
operation	Name of operation to be executed on server	String | Object	Yes	getThoughts, createThought { name: 'getUser', alias: 'getAdminUser' }
fields	Selection of fields	Array	No	['id', 'name', 'thought'] ['id', 'name', 'thought', { user: ['id', 'email'] }]
variables	Variables sent to the operation	Object	No	{ key: value } eg: { id: 1 } { key: { value: value, required: true, type: GQL type, list: true, name: argument name } eg: { email: { value: "[e-mail]", required: true }, password: { value: "123456", required: true }, secondaryEmails: { value: [], required: false, type: 'String', list: true, name: secondaryEmail } }

Adapter

An optional third argument adapter is a typescript/javascript class that implements IQueryAdapter, IMutationAdapter or ISubscriptionAdapter.

If adapter is undefined then src/adapters/DefaultQueryAdapter or src/adapters/DefaultMutationAdapter is used.

import { gqlQuery } as gql from 'gql-payload'

const query = gqlQuery(options: object, adapter?: MyCustomQueryAdapter,config?: object)

Config

Name	Description	Type	Required	Example
operationName	Name of operation to be sent to the server	String	No	getThoughts, createThought
fragment	Named fragment config for reusable fields to be sent to the server	Array	No	[{ name: "NamedFragment", on: "User", fields: ["grade"] }]
