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.
