The Apollo Explorer is a new tool for navigating graphs and building GraphQL queries in Apollo Studio. It aims to provide an intuitive experience for graph consumers, product engineering teams that work with production data graphs. The Explorer includes features like dynamic field selection, intelligent search, and built-in documentation to help users compose exactly the query they need. Its operation editor is built on Monaco and provides full IntelliSense support for GraphQL, including query linting, autocomplete, and peek definitions. The tool also enables users to "step into their schema" and build queries without typing, with features like automatic variable creation and intelligent search. Additionally, it includes a history tab to view previously executed queries and comes with both light and dark themes.
