Function createBaseURLMiddleware

Create a baseURL middleware

Creates middleware that automatically prepends a base URL to relative request URLs. Follows modern library patterns (axios, ky, ofetch) for URL handling.

Example: Basic usage

import { createFej, createBaseURLMiddleware } from 'fej';

const api = createFej();
api.use('baseURL', createBaseURLMiddleware({
  baseURL: 'https://api.example.com',
}), 100); // High priority to run early

// Request to '/users' becomes 'https://api.example.com/users'
await api.fej('/users');
Copy

Example: With absolute URL handling

api.use('baseURL', createBaseURLMiddleware({
  baseURL: 'https://api.example.com',
  allowAbsoluteUrls: false, // Force baseURL even for absolute URLs
}));
