Remix - Advanced Patterns

Identify the bug in this Remix loader for multi-tenant data fetching:

export async function loader({ request }) {
  const url = new URL(request.url);
  const tenant = url.pathname.split('/')[2];
  if (!tenant) throw new Error('Tenant missing');
  return { tenant };
}

ALoader must not return an object

BTenant index should be 1, not 2

CError should be returned, not thrown

DMissing await keyword before new URL()

Step-by-Step Solution

Solution:

Step 1: Analyze pathname splitting
Pathname split by '/' results in ['', tenant, ...]. Tenant is at index 1, not 2.
Step 2: Understand error condition
If tenant is at index 2, it will often be undefined, causing error even when tenant exists.
Final Answer:
Tenant index should be 1, not 2 -> Option B
Quick Check:
Tenant = pathname.split('/')[1] [OK]

Quick Trick: Tenant is always at index 1 after splitting pathname [OK]

Common Mistakes:

MISTAKES

Using wrong index for tenant extraction
Confusing async usage with URL constructor
Throwing error instead of handling gracefully
