We can create the most basic components of our GraphQL Schema using GraphQL's Object Types. These types allow us to group related fields together under a specific type, such as a Video or a User, and then allows us to fetch these types when we query…
When we have certain mutations that require more complex input parameters, we can leverage the Input Object Type in GraphQL. In this video, we’ll learn how to create an Input Object Type and how to add it to a GraphQL Mutation Type. const express = r…
In order to handle collections of items in a GraphQL Schema, GraphQL has a List Type. In this video, we’ll learn the syntax for specifying a List of items in a GraphQL Schema. Quey list of videos: const { graphql, buildSchema } = require('graphql');…

ypeScript 2.2 introduced the object, a type that represents any non-primitive type. It can be used to more accurately type methods such as Object.create. Don't confuse it with the Object type or {}, the empty object type, though! So one thing we need…

Interfaces are similar to Unions in that they provide a mechanism for dealing with different types of data. However, an interface is more suited for data types that include many of the same fields. In this lesson, we will query different types of pet…
Fragments are selection sets that can be used across multiple queries. They allow you to refactor redundant selection sets, and they are essential when querying unions or interface types. In this lesson, we will improve our query logic by creating a…

1. Type conversion: If we assign an out-of-range value to an object of unsigned type, the result is the remainder of the value modulo the number of values the target type can hold. If we assign an out-of-range value to an object of signed type, the r…
