## What Ports the Relay `graphql` tagged template transform (babel-plugin-relay / swc_relay) as an individual napi transform, per #24914: - **`crates/oxc_relay`** — the core transform as its own crate (modeled on `oxc_react_compiler`): replaces `graphql` tagged templates with references to relay-compiler artifacts. Definition names are extracted textually like `swc_relay` (equivalent to `\b(fragment|mutation|query|subscription)\s+(\w+)` with `#` comments stripped; hand-rolled scanner, no regex dependency). - **`napi/transform-relay`** (`oxc-transform-relay`) — standalone napi package copied from the `napi/transform-react` template: parse → semantic → relay traverse → codegen. Only `graphql` tags are rewritten; TypeScript/JSX syntax is preserved untouched, so the output composes with any downstream toolchain. ## Options | option | default | behavior | |---|---|---| | `artifactDirectory` | unset | when set, the import path is computed lexically relative to the transformed file (babel-plugin-relay `getRelativeImportPath` semantics — swc emits absolute paths instead); unset → `./__generated__/` next to the file | | `language` | `javascript` | `typescript` imports `Name.graphql.ts`, otherwise `Name.graphql.js` | | `eagerEsModules` | `true` | hoisted default imports (babel-plugin-relay ≥ v17 parity); `false` emits inline `require()` (`@swc/plugin-relay` / Next.js behavior) | A `graphql` tag with no extractable definition name produces an error diagnostic (babel throws; swc silently skips). Not supported, documented in both READMEs: dev-mode artifact hash validation, `jsModuleFormat: "haste"`, `isDevVariableName`, swc's Next.js-specific `projects`/`pagesDir`, and GraphQL document validation. closes #24914 --- Implemented with Claude Code.
