Apollo Language Server

The Apollo Language Server is a deprecated JavaScript/TypeScript package designed to provide advanced language features for Apollo GraphQL projects within integrated development environments (IDEs). Last actively maintained at version 1.26.9 and published approximately four years ago, it aimed to offer capabilities such as syntax highlighting, real-time validation, autocompletion, and schema navigation for GraphQL files and embedded GraphQL templates. Its core functionality has since been integrated directly into the official Apollo GraphQL VS Code extension and other Apollo tooling, rendering this standalone package largely obsolete for modern development. As such, it is no longer actively developed or recommended for new projects, with its primary function superseded by a more integrated editor experience. Developers should utilize the VS Code extension for current Apollo GraphQL language support.
