oxc_relay

Rust port of the Relay graphql tagged template transform (babel-plugin-relay / swc_relay).

Replaces graphql tagged template expressions with references to the artifact files generated by relay-compiler:

const data = graphql`
  query FooQuery {
    id
  }
`;

becomes (with eager_es_modules: true, the default):

import _FooQuery from "./__generated__/FooQuery.graphql.js";
const data = _FooQuery;

or (with eager_es_modules: false):

const data = require("./__generated__/FooQuery.graphql.js");

This crate backs the oxc-transform-relay Node.js package in napi/transform-relay.

Limitations

Compared to babel-plugin-relay:

No development-mode artifact hash validation (console.error on stale artifacts) — like swc_relay, the transform is production-shaped.
No jsModuleFormat: "haste" and no isDevVariableName.
The definition name is extracted textually (like swc_relay), not by parsing the GraphQL document, so documents are not validated.
