Why axify-js?

Most developers love Axios for its clean syntax and interceptors, but it comes with significant drawbacks:

| Feature | Axios | axify-js | |---------|-------|----------| | Bundle Size | 30kB+ | 2kB ⚡ | | Next.js Cache | ❌ No | ✅ Yes | | Request Deduplication | ❌ No | ✅ Yes | | Dependencies | Multiple | Zero 🎯 | | TypeScript | ✅ Yes | ✅ Full |

axify-js gives you the best of both worlds:

• ✅ Axios-like API - .get(), .post(), interceptors
• ✅ Next.js Native - Direct support for revalidate and tags
• ✅ Ultra-Lightweight - 15x smaller than Axios
• ✅ Zero Dependencies - No security vulnerabilities
• ✅ Request Deduplication - Prevents duplicate GET requests
• ✅ TypeScript First - Full autocomplete for all options

Installation

npm install axify-js

bash
# Yarn
yarn add axify-js

# pnpm
pnpm add axify-js

# Bun
bun add axify-js

🚀 Quick Start

The fastest way to make HTTP requests in Next.js

Get started with axify-js in under 60 seconds - the lightweight alternative to Axios for Next.js 14/15, React Server Components, and TypeScript projects.

1. Basic GET Request

import { get } from 'axify-js';

// Simple GET request - returns data directly (no .data wrapper)
const products = await get('https://api.example.com/products');
console.log(products);

2. POST Request with JSON body

import { post } from 'axify-js';

// POST request with automatic JSON serialization
const newUser = await post('/api/users', {
  name: 'Sushil',
  email: '[email protected]'
});

3. PUT and PATCH Requests

import { put, patch } from 'axify-js';

// Update entire resource
const updatedUser = await put('/api/users/1', {
  name: 'Sushil Kumar',
  email: '[email protected]'
});

// Partial update
const patchedUser = await patch('/api/users/1', {
  name: 'Sushil K.'
});

4. DELETE Request

import { del } from 'axify-js';

// Delete a resource
await del('/api/users/1');
console.log('User deleted successfully');

5. 🔥 Next.js Caching (The Killer Feature)

Unlike Axios, axify-js works seamlessly with Next.js native caching:

// ISR-style revalidation - perfect for Next.js App Router
const data = await get('/api/stats', {
  next: { 
    revalidate: 3600,        // Cache for 1 hour (ISR)
    tags: ['dashboard-stats'] // Purge with revalidateTag()
  },
  cache: 'force-cache'        // Use Next.js data cache
});

6. Create a Reusable API Client

import { create } from 'axify-js';

// Best practice: Create a configured instance for your API
export const api = create({
  baseUrl: process.env.NEXT_PUBLIC_API_URL || 'https://api.myapp.com/v1',
  headers: {
    'Authorization': `Bearer ${process.env.API_TOKEN}`,
    'Content-Type': 'application/json'
  },
  timeout: 5000 // 5 second timeout
});

// Use anywhere in your Next.js app
const user = await api.get('/users/123');

7. Interceptors for Authentication

// Automatic token refresh & error handling
const http = create({ baseUrl: 'https://api.example.com' }, {
  request: (config) => {
    // Add auth token to every request
    config.headers.Authorization = `Bearer ${localStorage.getItem('token')}`;
    return config;
  },
  response: (data) => {
    // Transform response data globally
    return data.result;
  },
  error: async (err) => {
    if (err.status === 401) {
      // Auto-refresh token (great for JWT)
      const newToken = await refreshAccessToken();
      localStorage.setItem('token', newToken);
      return retryRequest(err.config);
    }
    return Promise.reject(err);
  }
});

💡 Pro Tips for Next.js Developers

// ✅ DO: Use in Server Components
export default async function Page() {
  const data = await get('https://api.example.com/posts', {
    next: { revalidate: 60 } // Cache for 60 seconds
  });
  return <div>{data.title}</div>;
}

// ✅ DO: Deduplicate requests automatically
const [user, posts] = await Promise.all([
  get('/api/user'),    // Only 1 network request
  get('/api/user'),    // Deduplicated!
  get('/api/posts')
]);

// ✅ DO: Use cache tags for fine-grained control
await get('/api/dashboard', {
  next: { tags: ['dashboard', 'user-123'] }
});

// Later, revalidate specific tags
import { revalidateTag } from 'next/cache';
revalidateTag('dashboard'); // Only this cache is purged

Core Features

🔄 Request Deduplication

Automatically prevents duplicate in-flight GET requests:

// These three requests will only execute once!
const [user1, user2, user3] = await Promise.all([
  get('/api/user/profile'),
  get('/api/user/profile'),
  get('/api/user/profile')
]);
// Only 1 network request is made 🎉

⏱️ Timeout Handling

const data = await get('/api/slow-endpoint', {
  timeout: 3000 // 3 seconds timeout
});
// Throws error if request takes longer than 3 seconds


🔌 Custom Headers
const data = await get('/api/protected', {
  headers: {
    'X-API-Key': 'your-api-key',
    'X-Custom-Header': 'custom-value'
  }
});

@param interceptors - Global interceptors for this instance

@returns Configured instance with all HTTP methods

Example:

  // Create instance with base URL and auth interceptor
  import {create} from 'axify-js'
  const api = create(
    { 
      baseUrl: 'https://api.example.com',
      timeout: 5000 
    },
   {
      // Request interceptor - runs before every request
      request: (config) => {
        config.headers.Authorization = `Bearer ${getToken()}`;
        return config;
     },
      
      // Response interceptor - runs on successful responses
     response: (data) => {
       return data.results; // Unwrap nested data
     },
     
      // Error interceptor - runs on errors
      error: (error) => {
        console.error('API Error:', error.status);
      throw error;
     }
    }
  );

Error Handling

try {
  const data = await get('/api/protected');
} catch (error) {
  if (error.status === 401) {
    console.log('Unauthorized - redirect to login');
  } else if (error.status === 404) {
    console.log('Resource not found');
  } else if (error.status === 429) {
    console.log('Rate limited - retry later');
  } else if (error.name === 'TimeoutError') {
    console.log('Request timeout');
  } else {
    console.log('Network error:', error.message);
  }
}

Advanced Usage

File Upload with Progress

const formData = new FormData();
formData.append('file', fileInput.files[0]);
formData.append('name', 'example.jpg');

const response = await post('/upload', formData, {
  headers: {
    'Content-Type': 'multipart/form-data'
  },
  onProgress: (percent) => {
    console.log(`Upload progress: ${percent}%`);
  }
});

Request Cancellation

const controller = new AbortController();

try {
  const data = await get('/api/slow-endpoint', {
    signal: controller.signal
  });
} catch (error) {
  if (error.name === 'AbortError') {
    console.log('Request was cancelled');
  }
}

// Cancel the request after 2 seconds setTimeout(() => controller.abort(), 2000);

Custom Error Handling with Retry Logic

async function fetchWithRetry(url: string, retries = 3) {
  for (let i = 0; i < retries; i++) {
    try {
      return await get(url);
    } catch (error) {
      if (i === retries - 1) throw error;
      // Exponential backoff
      await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, i)));
    }
  }
}

const data = await fetchWithRetry('/api/unreliable-endpoint');

Batch Requests

// Automatic request deduplication for GET requests
const [users, posts, comments] = await Promise.all([
  get('/api/users'),
  get('/api/users'),     // Deduplicated - no second request!
  get('/api/posts')
]);


// For POST/PUT requests, they'll execute in parallel
const results = await Promise.all([
  post('/api/users', user1),
  post('/api/users', user2),
  post('/api/users', user3)
]);

Authentication Flow

// Setup auth interceptor
const api = create(
  { baseUrl: 'https://api.example.com' },
  {
    request: (config) => {
      const token = localStorage.getItem('access_token');
      if (token) {
        config.headers.Authorization = `Bearer ${token}`;
      }
      return config;
    },
    error: async (error) => {
      if (error.status === 401) {
        // Refresh token
        const refreshToken = localStorage.getItem('refresh_token');
        try {
          const { access_token } = await post('/auth/refresh', { refreshToken });
          localStorage.setItem('access_token', access_token);
          // Retry original request
          return api.request(error.config);
        } catch (refreshError) {
          // Redirect to login
          window.location.href = '/login';
        }
      }
      throw error;
    }
  }
);

Migration from Axios

Switching from Axios to axify-js is straightforward:

Step 1: Update imports

// Before (Axios)
import axios from 'axios';

// After (axify-js)
import { get, post, create } from 'axify-js';

Step 2: Update GET requests

// Axios
const response = await axios.get('/api/users');
const users = response.data;

// axify-js
const users = await get('/api/users'); // Direct access!

Step 3: Update POST requests

// Axios
const response = await axios.post('/api/users', { name: 'John' });
const user = response.data;

// axify-js
const user = await post('/api/users', { name: 'John' });

Step 4: Update instances

// Axios
const api = axios.create({
  baseURL: 'https://api.example.com',
  timeout: 5000
});

// axify-js
const api = create({
  baseUrl: 'https://api.example.com', // Note: baseUrl (not baseURL)
  timeout: 5000
});

Step 5: Update interceptors

// Axios
axios.interceptors.response.use(
  response => response.data,
  error => Promise.reject(error)
);

// axify-js
const api = create({}, {
  response: (data) => data,
  error: (error) => Promise.reject(error)
});

Troubleshooting

Common Issues & Solutions

// Issue 1: CORS errors in browser
// Solution: Configure CORS on your server or use proxy in Next.js
// next.config.js
module.exports = {
  async rewrites() {
    return [{ source: '/api/:path*', destination: 'https://api.example.com/:path*' }];
  }
};

// Issue 2: Timeout errors
const data = await get('/api/slow', { timeout: 10000 }); // Increase timeout

// Issue 3: Cache not working in Next.js
// Solution: Ensure you're using the correct cache option
await get('/api/data', { 
  cache: 'force-cache',
  next: { revalidate: 60 }
});


// Issue 4: TypeScript errors
// Solution: Install types (included by default)
import type { AxifyConfig } from 'axify-js';
