Techniques for API Aggregation

1. Introduction

API aggregation is the process of combining multiple APIs into a single access point, allowing for efficient data retrieval, management, and interaction. In a headless and composable architecture, this technique enhances the flexibility and scalability of applications.

3.1 Example of a Custom Aggregator Service

const express = require('express');
const axios = require('axios');
const app = express();

app.get('/aggregate', async (req, res) => {
    try {
        const [data1, data2] = await Promise.all([
            axios.get('https://api.example1.com/data'),
            axios.get('https://api.example2.com/data')
        ]);
        res.json({ data1: data1.data, data2: data2.data });
    } catch (error) {
        res.status(500).send('Error fetching data');
    }
});

app.listen(3000, () => console.log('Aggregator service running on port 3000'));
            

4. Best Practices

• Choose the right aggregation technique based on your application’s needs.
• Implement error handling to manage failures gracefully.
• Optimize performance using caching strategies for frequently accessed data.
• Monitor and log API usage to identify bottlenecks and improve efficiency.
