In the fast-growing GraphQL program there are several popular GraphQL clients available today including Apollo Client, URQL, and Lokka.
In the process of building a more flexible operating system with AWS GraphQL hosted AWS AppSync, the AWS team has created a new GraphQL client.
Because it works well with almost any GraphQL API or service, and they decided to open it. The AWS Amplify GraphQL client provides a simple API, designed to get up and running quickly with minimal configuration.
The AWS Amplify GraphQL client has been released from React Amsterdam as well as the regular availability of AWS AppSync.
The AWS Amplify GraphQL client supports conversions, registrations, and queries and is actively developed.
We still support our AppSync Apollo SDK with advanced use cases such as temporary storage and offline support. If you are interested in those features, check out the Apollo Client for General GraphQL APIs or the AWS AppSync Apollo SDK for use with the AWS AppSync API.

First one is to define the query, and perform the GraphQL operation.
- Defining the query using template literals as shown below:
2. Now, Perform the GraphQL operation as told before:
Now Adding parameters or options:
To create a straightforward transition, we still need only two modes from Amplify:
