@swwind/remove-exports

Remove specific named exports in a JS file, also removes non-used imports and declarations caused by removal.

Used for tree shaking server-specific codes in full-stack js frameworks.

import { database } from "backend";
import { useState } from "frontend";

const USER_NAME = "admin";

export const findUser = async () => {
  return await database.findUser(USER_NAME);
};

export function Component() {
  const [count, setCount] = useState(0);
  return <div>{count}</div>;
}

// import { database } from "backend";
import { useState } from "frontend";
import "./style.css";

// const USER_NAME = "admin";

// export const findUser = async () => {
//   return await database.findUser(USER_NAME);
