+This is alpha software and may yield incorrect results, feel free to [submit a bug report](https://github.com/oxc-project/oxc/issues/new?assignees=&labels=C-bug&projects=&template=bug_report.md).
+
+## TypeScript and React JSX Transform
+
+```javascript
+import assert from 'assert';
+import oxc from 'oxc-transform';
+
+const { code, declaration, errors } = oxc.transform(
+  "test.ts",
+  "class A<T> {}",
+  {
+    typescript: {
+      declaration: true, // With isolated declarations in a single step.
+    },
+  },
+);
+
+assert.equal(code, "class A {}\n");
+assert.equal(declaration, "declare class A<T> {}\n");
+assert(errors.length == 0);
+```
