4. Server Hooks: These are a standout feature. They allow you to easily implement complex request patterns like retries, rate limiting, or custom logic without cluttering your main code.

5. Performance Optimization: With features like memory mode and restore mode, alovajs gives you fine-grained control over how you balance speed and resource usage.

Now that I’ve got your attention, let’s roll up our sleeves and see this bad boy in action!

Getting Down and Dirty with alovajs on the Server

Installation and Setup

First things first, let’s get alovajs into your project. Open up your terminal and type in one of these magic spells:

# npm aficionados
npm install alova --save

# yarn yarn-ers
yarn add alova

# pnpm people
pnpm add alova

# bun buddies
bun add alova

Now, let’s create an alovajs instance. It’s like summoning your own personal request genie:

import { createAlova } from 'alova';
import adapterFetch from 'alova/fetch';

const alovaInstance = createAlova({
  requestAdapter: adapterFetch(),
  responded: response => response.json()
});

Pro tip: If you’re running Node.js and it’s throwing a fit about fetch, make sure you’re on v17.5 or later. Otherwise, you might want to cozy up with the Axios adapter instead.

Basic Request Operations

Ready to make your first request? It’s as easy as pie:

const response = await alovaInstance.Get('https://alovajs.dev/user/profile');

Boom! You’ve just made a GET request. It’s so simple, it almost feels like cheating, doesn’t it?

Need to send some data? alovajs has got your back:

const response = alovaInstance.Post('https://alovajs.dev/posts', {
  title: 'alovajs: The Server-Side Superhero',
  body: 'This library is so cool, it makes ice jealous.',
  userId: 1
});

Advanced Features: Server Hooks

Now, let’s talk about the secret sauce - Server Hooks. These bad boys let you add superpowers to your requests. Check this out:

const { retry, sendCaptcha } = require('alova/server');

const email = 'cooldev@example.com';
const captchaMethod = alovaInstance.Post('/api/captcha', {
  email,
  content: 'Are you a robot? Prove it!'
});

const retryingMethod = retry(captchaMethod, {
  retry: 3,
  backoff: {
    delay: 2000
  }
});

const result = await sendCaptcha(retryingMethod, {
  key: email
});

This little snippet is like the Swiss Army knife of server requests. It’s retrying the captcha send, and it’s doing it with style!

Caching Strategies

Remember when I mentioned multi-level caching? Well, buckle up, because this is where things get really interesting:

const { createPSCAdapter, NodeSyncAdapter } = require('@alova/psc');
const { LRUCache } = require('lru-cache');
const RedisStorageAdapter = require('./adapter-redis');

function lRUCache(options = {}) {
  const cache = new LRUCache(options);
  return {
    set: (key, value) => cache.set(key, value),
    get: key => cache.get(key),
    remove: key => cache.delete(key),
    clear: () => cache.clear()
  };
}

const alovaInstance = createAlova({
  baseURL: 'https://api.alovajs.dev',
  l1Cache: createPSCAdapter(
    NodeSyncAdapter(),
    lRUCache({
      max: 1000,
      ttl: 1000 * 60 * 10
    })
  ),
  l2Cache: new RedisStorageAdapter({
    host: 'localhost',
    port: 6379,
    username: 'default',
    password: 'super-secret-password',
    db: 0
  })
});

This setup is like giving your server a photographic memory. LRU cache for quick access, Redis for the long haul. Your server will be serving responses faster than a caffeinated barista!

Let’s visualize how this multi-level caching works:

This multi-level caching strategy ensures blazing-fast responses while maintaining data consistency.

Performance Optimization Modes

Sometimes, you need responses faster than the speed of light. That’s where Memory Mode comes in:

alovaInstance.GET('/todo/list', {
  cacheFor: {
    mode: 'memory',
    expire: 60 * 10 * 1000 // 10 minutes in milliseconds
  }
});

Word of caution: With great power comes great responsibility. Don’t go cache-crazy, or your server’s memory might throw a tantrum.

Last but not least, let’s talk about Restore Mode. It’s like having a safety net for your high-flying cache trapeze act:

const todoListGetter = alovaInstance.Get('/todo/list', {
  cacheFor: {
    mode: 'restore',
    expire: 60 * 10 * 1000
  }
});

This mode is perfect for when you want the speed of in-memory caching with the reliability of persistent storage. It’s like having your cake and eating it too!

Real-World Application: alovajs in Action

Let’s consider a real-world scenario where alovajs shines. Imagine you’re building a high-traffic e-commerce platform that needs to display real-time product availability across multiple regions.

Here’s how you might implement this with alovajs:

const getProductAvailability = alovaInstance.Get('/api/product/:id/availability', {
  params: { id: '@id' },
  cacheFor: {
    mode: 'restore',
    expire: 60 * 1000 // 1 minute
  }
});

const { retry } = require('alova/server');

const getReliableProductAvailability = retry(getProductAvailability, {
  retry: 3,
  backoff: { delay: 1000 }
});

async function checkAvailability(productId) {
  try {
    const availability = await getReliableProductAvailability({ params: { id: productId } });
    return availability;
  } catch (error) {
    console.error(`Failed to fetch availability for product ${productId}`, error);
    return null;
  }
}

In this example, we’re using alovajs to:

1. Create a reusable method for fetching product availability
2. Implement caching with a 1-minute expiry to reduce load on the backend
3. Use the retry server hook to ensure reliability even if the initial request fails
4. Wrap it all in a function that’s easy to use throughout the application

This setup allows for efficient, reliable, and fast product availability checks, which is crucial for a smooth user experience in an e-commerce setting.
