Function createFej

Create a new Fej instance with configuration

Factory function for creating isolated Fej instances with custom configuration. This is the recommended way to use Fej in v2.

Example: Basic instance

import { createFej } from 'fej';

const api = createFej();
const response = await api.fej('https://api.example.com/users');
Copy

Example: With configuration

const api = createFej({
  retry: {
    attempts: 3,
    delay: 1000,
    backoff: 'exponential',
  },
  errorTransforms: [
    async (error, ctx) => {
      console.error(`Request failed: ${ctx.request.url}`);
      return error;
    },
  ],
});
Copy

Example: Multiple instances

const userApi = createFej({ retry: { attempts: 5 } });
const paymentApi = createFej({ retry: { attempts: 10 } });
// Each instance has independent configuration and middleware
Copy
