See it in action

Before:

const fetchUser = async(userId,options)=>{
const res = await fetch('/api/users/'+userId,{method:'GET',headers:{'Content-Type':'application/json'}})
if(!res.ok){throw new Error('Request failed with status '+res.status)}
const data=await res.json()
return {id:data.id,name:data.name,email:data.email,role:data.role||'user'}
}

Run:

formah api.js

After — Airbnb:

const fetchUser = async (userId, options) => {
  const res = await fetch(`/api/users/${userId}`, {
    method: 'GET',
    headers: { 'Content-Type': 'application/json' },
  });

  if (!res.ok) {
    throw new Error(`Request failed with status ${res.status}`);
  }

  const data = await res.json();

  return {
    id: data.id,
    name: data.name,
    email: data.email,
    role: data.role || 'user',
  };
};

The file is saved in-place. No config files, no extra steps.
