In modern front-end development, managing HTTP requests is becoming increasingly complex. Between loading states, error handling, caching, synchronization, and interdependent requests, a simple fetch or even axios is often no longer sufficient. This is where Alova.js positions itself as a reactive, complete, and elegant solution.
✨ What is Alova.js?
Alova.js is a JavaScript library designed to handle HTTP requests reactively, with native integration into modern frameworks like React, Vue, and Svelte. Its goal: to centralize network logic, automate state management (loading, data, error), and reduce boilerplate in UI components.
The name stands for Abstract Layer of Various API, and its architecture reflects that: abstraction, modularity, and extensibility.
⚙️ Main Features
1. Built-in Reactive Requests
Alova provides hooks like useRequest, useWatcher, usePagination, etc., which return reactive states directly usable in your components.
const { loading, data, error } = useRequest(() =>
alova.Get('/posts'), { immediate: true });
2. Automatic State Management
No need to write repetitive useState or useEffect: Alova handles it for you.
3. Smart Caching
Each request can cache data with rules for expiration or refresh.
4. Conditional and Dependent Requests
With useWatcher, you can trigger requests based on state changes or dependencies.
useWatcher(() => alova.Get(`/users/${userId}`), [userId]);
5. Centralized Configuration
Headers, transformations, errors, etc. are defined once in the alova instance.
const alova = createAlova({
baseURL: 'https://api.example.com',
statesHook: ReactHook,
beforeRequest(method) {
method.config.headers.Authorization = 'Bearer token';
},
});
🧠 Why Choose Alova.js?
Classic Axios Example
useEffect(() => {
axios.get('/posts')
.then(res => setData(res.data))
.catch(setError)
.finally(() => setLoading(false));
}, []);
With Alova.js
const { loading, data, error } = useRequest(() =>
alova.Get('/posts'), { immediate: true });
Result: Less code, better readability, automatic states.
🔒 Ideal For
- SPAs built with React/Vue/Svelte
- Projects that need caching and pagination
- Apps requiring automatic loading/error/data handling
📦 Installation
npm install alova
# or
yarn add alova
React Setup
import ReactHook from 'alova/react';
import { createAlova } from 'alova';
const alova = createAlova({
baseURL: '/api',
statesHook: ReactHook
});

🚀 Conclusion
Alova.js is not just another HTTP client. It’s a modern, efficient, and developer-friendly tool to manage requests in modern front-end apps. Compared to Axios, it offers better reactivity, less boilerplate, and more scalability for real-world use cases.
