Here is an example of how you can write code for backend development:

const express = require ( ‘express’ );

const app = express ( );

app . get ( ‘ / ’, ( req , res ) = > res . send ( ‘ Hello from Node.js backend!’ ));

app . listen ( 3000 );

2. Python

Readability and simplicity are the two key qualities of Python language making it popular among developers. Django framework of Python enables rapid development, practical, and clean design as well. On the other hand, FastAPI is a relatively new framework that builds performant REST APIs.

Moreover, it is easy to understand, good for data-intensive applications and machine learning, and has built-in tools for user authentication, security, and admin interfaces. Some popular use cases include data dashboards, APIs, machine learning models, and web applications.

An example of FastAPI usage:

from fastapi import FastAPI

app = FastAPI ( )

@ app . get ( “/ ” )

def read_root ( );

return { “ message ” : “ Hello from FastAPI” }

3. Java

For enterprise-level backend systems, Java has been a favorite choice. Sprit Boot, which is a Java-based web development framework, makes development easy by offering embedded servers, integrations, and pre-configured templates. Moreover, it’s dynamic and secure to work with and backs microservices architecture, that can be done easily by hiring expert Java developers.

Important use cases include banking systems, complex business logic implementation, and complex applications.

You can follow this example for backend development with Spring Boot:

@ RestController

@ SpringBootApplication

public class App {

public static void main ( String [ ] args ) {

SpringApplication . run ( App . class , args );

}

@ GetMapping ( “ / ” )

public String home ( ) {

return “ Hello from Spring Boot!” ;

}

}

4. PHP

An advanced PHP framework, Laravel facilitates the development process with the help of powerful features and syntax. This framework follows MVC pattern and takes care of everything required to build full-featured applications.

Its key advantages include authentication, routing, and caching, CLI making repetitive tasks easy, and eloquent ORM facilitating database interactions. Some use cases include e-commerce platforms, SaaS products, and content management systems.

Example:

Route :: get ( ‘ / ’ , function ( ) {

return ‘Hello from Laravel’ ;

});

5. Ruby

For rapid development of web applications, Ruby on Rails is an ideal platform. Moreover, it has all the tools needed to design a complete web application from background jobs to database migrations. Moreover, it offers faster development with less code, supportive community, and excellent testing tools.

Some use cases include social media applications, MVPs, and startups.

Here is an example of how you can use Ruby on Rails:

class HomeController < ApplicationController

def index

render plain : “Hello from Rails”

end

Supporting Backend Development Technologies

Backend web development is supported by various technologies to ensure scalability, security, and optimal performance. These technologies take care of caching, server management, data storage, and messages.

1. Databases: For structure data, relational databases like PostgreSQL and MySQL are used. For semi structured or unstructured data, NoSQL databases like Cassandra and MongoDB are more suitable.

2. Caching Systems: Through caching, by storing frequently accessed data in memory, performance is improved. For caching systems Memcached and Redis are the popular choices.

3. Message Brokers: Asynchronous communication between services is enabled by message brokers. The most widely used message brokers are Apache Kafka and RabbitMQ. They also make applications more scalable and resilient.

4. Management: Powerful web servers manage load balancing, client requests, and static file delivery. Prominent server systems include Apache and NGINX.
