Unexpected token error on typescript components

[Will Liu]

I am getting this error when trying to parse some of my typescript components. The components are definitely valid typescript.

SyntaxError: unknown: Unexpected token (22:50)

  20 |  */
  21 | const Item = React.forwardRef<
> 22 |   React.ElementRef<typeof AccordionPrimitive.Item>,
     |                                                   ^
  23 |   React.ComponentPropsWithoutRef<typeof AccordionPrimitive.Item>
  24 | >(({ className, ...props }, ref) => (
  25 |   <AccordionPrimitive.Item

Reproducible example using "react-docgen": "^5.4.3"

const reactDocs = require("react-docgen");

const code = `
import * as React from "react";
import * as AccordionPrimitive from "@radix-ui/react-accordion";

import { cn } from "../utils";

export const Accordion = (
  props: React.ComponentProps<typeof AccordionPrimitive.Root>
) => {
  return <></>;
};

const Root = AccordionPrimitive.Root;
Root.displayName = AccordionPrimitive.Root.displayName;
Accordion.Root = Root;

/**
 * Default Classes: ~ "border-b border-b-line" ~
 * sdiofh
 */
const Item = React.forwardRef<
  React.ElementRef<typeof AccordionPrimitive.Item>,
  React.ComponentPropsWithoutRef<typeof AccordionPrimitive.Item>
>(({ className, ...props }, ref) => (
  <AccordionPrimitive.Item
    ref={ref}
    className={cn("border-b border-b-line", className)}
    {...props}
  />
));
Item.displayName = "Accordion.Item";
Accordion.Item = Item;
`;

console.log(reactDocs.parse(code));

Typescript is only activated when the filename is either .ts or .tsx or there is babel config that activates typescript. In your case you have to provide a filename

console.log(reactDocs.parse(code, { filename: 'file.tsx' }));
