Deno, a JavaScript runtime created by the developers behind Node.js, is gaining popularity for its features such as enhanced security, module handling, and dependency management, which address some of Node.js's limitations. Built on the Google V8 Engine, Deno supports both JavaScript and TypeScript and operates in a sandbox environment that requires explicit permissions for network and file system access. This article illustrates how to set up a REST API using Deno, JavaScript, and a Postgres database, focusing on creating a basic CRUD application for managing a list of beers. It details the project setup, including the creation of services, controllers, and a database connection, while highlighting Deno's middleware framework Oak, which is inspired by Koa. The article emphasizes Deno's ability to manage dependencies through direct URL imports, eliminating the need for a package.json file, and offers insights into testing the API using tools like Postman. It concludes by showcasing Deno's efficiency in developing applications without Node.js and encourages exploration of its TypeScript capabilities.
