Learn about GraphQL, how it works step by step
Applications that are data-driven depend on remote queries that run through APIs. For years, web services have provided basic support for simple query structures. Those services, however, often constrained developers who needed more granular approaches that provided flexibility without creating a huge collection of unnecessary calls. GraphQL-a query language for APIs that was originally built by Facebook-allows developers to choose the kinds of requests they want to make, and receive information on multiple facets of that query in one request. The GraphQL approach to querying across networks can address a wide variety of large-scale development problems. GraphQL enables you to nest multiple request in one query.
In this course, you will learn how to get started with GraphQL step by step learning the basics of this query language, fetching data ,handling data,querying schema,creating variable definitions,creating mutations,creating fragments and getting you up to speed with the syntax and vocabulary of GraphQL. The course explains how to create basic queries, including how to work with arguments and multiple fields. Also you will learn complex techniques for handling data, including working with aliases, fragments, and pagination. Plus, how to edit and transform data with mutations.
