Graplix

Graplix is a TypeScript-first toolkit for modeling and evaluating ReBAC (Relation-Based Access Control).

• Define authorization relationships with .graplix schema files.
• Parse and validate schemas with language tooling.
• Evaluate permissions at runtime with resolver-driven engine APIs.
• Generate typed helpers and runtime wrappers with codegen.
• Use VS Code language support for authoring and navigation.
