Complete Guide to Fetch API with Examples

The Fetch API provides a powerful and flexible way to make HTTP requests in JavaScript. This guide demonstrates each option with practical examples.

Basic Structure

fetch(resource, options)
  .then(response => response.json())
  .then(data => console.log(data))

/**
route 
**/
import { fetchTransactionCount } from "../controller/transactionCountController.js"; // Ensure the correct path

export default async function transactionRoutes(fastify, options) {
  fastify.post("/num", async (request, reply) => {
    return fetchTransactionCount(request, reply);
  });
}

// routes/hello.js

"use strict";

export default async function (fastify, opts) {

    fastify.get(
        
        '/hello',
        async function (request, reply) {

The two code snippets are essentially doing the same thing, but they differ in how they handle imports and module syntax. Let's break down the key differences:

### 1. **ES Modules (First Example)**

```javascript
import path from 'path'
import autoLoad from 'fastify-autoload'
import { fileURLToPath } from 'url'
import { dirname, join } from 'path'
import fastify from 'fastify'
