GraphQL Analyzer

Diagnostics

GraphQL Analyzer provides real-time diagnostics as you type, showing validation errors and lint warnings inline in your editor.

What’s checked

Section titled “What’s checked”
  • GraphQL spec validation — Full GraphQL spec validation via the project’s analysis layer
  • Schema type checking — Fields, arguments, types validated against your schema
  • Lint rules — Configurable rules for best practices
  • Position-accurate — Correct line/column even for embedded GraphQL in TypeScript/JavaScript

How it works

Section titled “How it works”
File opened    → Full validation
File changed   → Re-validate changed document only
File saved     → Re-validate changed document
Schema changed → Re-validate all documents

Only the file you’re editing is recomputed — the rest of the project is cached. This keeps diagnostics fast even in large codebases.

Performance

Section titled “Performance”

By default, the LSP runs only fast, per-document rules in real-time. Expensive project-wide rules (like noUnusedFields) are disabled in the LSP and can be run via the CLI instead.

See Performance Tuning for configuration.
