After two years of development introduced<\/a><\/noindex> the first significant release Deno 1.0<\/a><\/noindex>, a platform for the isolated execution of applications in JavaScript and TypeScript, which can be used to create server-side handlers. The platform is developed by Ryan Dahl (Ryan Dahl<\/a><\/noindex>), the creator of Node.js. Like Node.js, Deno uses the JavaScript engine V8<\/a><\/noindex>, which is also used in Chromium-based browsers. However, Deno is not a fork of Node.js, but rather a completely new project created from scratch. The project's code is distributed<\/a><\/noindex> is licensed under the MIT License. Builds are prepared<\/a><\/noindex> are available for Linux, Windows, and macOS.<\/p>\n

The significant version number is associated with the stabilization of the APIs in the Deno namespace, which are responsible for the interaction of applications with the OS. APIs that are currently unstable<\/a><\/noindex>, by default are hidden and only accessible when running in «—unstable» mode. As new versions are developed, such APIs will gradually be classified as stable. The API in the global namespace, which includes common functions like setTimeout() and fetch(), is designed to be as close as possible to the APIs of standard web browsers and is evolving in accordance with web standards for browsers. The Rust APIs provided, which are used directly in the platform's code, as well as the interface for developing plugins for the Deno runtime, have not yet been stabilized and continue to evolve.<\/p>\n

The key motivations for creating the new JavaScript platform were the desire to eliminate conceptual errors that were made<\/a><\/noindex> in the architecture of Node.js, and to provide users with a more secure environment. To enhance security, the wrapper around the V8 engine is written in Rust, which helps avoid many vulnerabilities that arise from low-level memory operations, such as accessing memory after it's been freed, dereferencing null pointers, and buffer overflows. For handling requests in a non-blocking manner, the platform uses Tokio<\/a><\/noindex>, also written in Rust. Tokio allows the creation of high-performance applications based on event-driven architecture, supporting multithreading and asynchronous network request handling.<\/p>\n
