Simple REST API — Loopback Code

Demonstrates a simple LoopBack application with a Todo model and REST API endpoints for CRUD operations.

// common/models/todo.model.js
module.exports = function(Todo) {
  Todo.validatesPresenceOf('title');
};

// server/server.js
const loopback = require('loopback');
const boot = require('loopback-boot');
const app = loopback();

boot(app, __dirname, function(err) {
  if (err) throw err;

  // Create a sample Todo item
  const Todo = app.models.Todo;
  Todo.create({ title: 'Sample Task', completed: false });

  app.listen(3000, () => console.log('LoopBack API listening on port 3000'));
});

Loopback Language Guide

LoopBack is a highly extensible Node.js framework for building APIs and microservices quickly. It provides out-of-the-box support for REST APIs, data sources, and integration with databases and services.

Primary Use Cases

  • ▸Enterprise REST APIs
  • ▸Microservices architecture
  • ▸API gateways and backend services
  • ▸Integration with databases, SaaS, and legacy systems
  • ▸Rapid prototyping of data-driven applications

Notable Features

  • ▸Automatic REST API generation from models
  • ▸Data source connectors for SQL/NoSQL/databases and external APIs
  • ▸Strong authentication and authorization mechanisms
  • ▸API Explorer UI for testing and documentation
  • ▸Highly extensible via mixins and middleware

Origin & Creator

Originally created by StrongLoop (acquired by IBM) in 2013 and maintained as an open-source Node.js framework.

Industrial Note

LoopBack is widely used in enterprise applications, microservices, and cloud-based APIs where rapid API development, standardization, and multi-database connectivity are important.
