WPGraphQL

WPGraphQL is a free, open-source WordPress plugin that provides an extendable GraphQL schema and API for any WordPress site. WPGraphQL allows you to separate your CMS from your presentation layer. Content creators can use the CMS they know, while developers can use the frameworks and tools they love. Build rich JavaScript applications with WordPress and GraphQL. With GraphQL, the client makes declarative queries, asking for the exact data needed, and exactly what was asked for is given in the response, nothing more. This allows the client to have control over their application and allows the GraphQL server to perform more efficiently by only fetching the resources requested. GraphQL queries allow access to multiple root resources, and also smoothly follow references between connected resources. While a typical REST API would require round-trip requests to many endpoints, GraphQL APIs can get all the data your app needs in a single request.
