Deno 2.9 has been released, designed for isolated execution of server and desktop applications in JavaScript and TypeScript using the V8 engine, which is used in Chromium-based browsers. The project is led by Ryan Dahl, the creator of Node.js, aiming to provide a more secure environment and address design flaws in Node.js architecture. To enhance security, the wrapper around the V8 engine is written in Rust, and for handling requests in a non-blocking manner, the Tokio platform is used. The project's code is distributed under the MIT license. Builds are prepared for Linux, Windows, and macOS.<\/p>\n

The new version is notable for the implementation of the experimental Deno Desktop toolkit, allowing the creation of user applications with graphical interfaces built using web technologies, similar to the Electron platform. The logic and interface of the application are defined in JavaScript or TypeScript using standard web frameworks, and the functionality is organized using a browser engine. The application is delivered as a self-contained executable file and interacts with users just like traditional GUI programs.<\/p>\n

Deno Desktop offers backends that work atop two browser engines \u2014 the one provided by the operating system, WebView, and the integrated CEF (Chromium Embedded Framework) application. The WebView-based backend allows for a reduction in the size of executable files by leveraging the system's browser engine, WebView2 on Windows and WebKit on macOS and Linux. Meanwhile, the CEF backend enables consistent interface rendering across Linux, macOS, and Windows platforms, albeit at the cost of a significant increase in the size of executable files. <\/p>\n

The size of the executable file for the test application using WebView is estimated at 40 MB, while using CEF it is 150 MB. In comparison, Electron's figure is 100 MB, Electrobun is 61 MB, and Tauri is between 2-10 MB (Electron uses an embedded CEF within the application, while Electrobun and Tauri utilize the system WebView). A mechanism for sharing a common CEF engine across different applications is in development, which will help reduce the size of executable files.<\/p>\n

Deno Desktop offers full compatibility with Node.js, the NPM ecosystem, and web frameworks such as Next.js, Astro, Fresh, Remix, Nuxt, SvelteKit, SolidStart, TanStack Start, and Vite SSR. It provides an API for accessing native desktop APIs, allowing control over window size, position, and visibility, as well as creating menus, attaching custom handlers, setting system tray and panel icons, and displaying native OS dialogs. It facilitates the assembly of web applications into desktop programs without altering their code, along with automatic detection of used web frameworks and cross-compilation on a single system for Linux x64\/arm64, Windows x64, and macOS x64\/arm64. For Linux, it can generate packages in AppImage, deb, and rpm formats.<\/p>\n

Unlike Electron, Electrobun, and Tauri, Deno Desktop uses a multithreaded model for CEF or a group process-based model for WebView, allowing interaction between the backend and the graphical interface code through channels within a single process, rather than a multiprocess execution model with IPC based on sockets. It features a built-in mechanism for checking and automatically installing updates that conserves bandwidth by downloading only data changed since the previous version (using binary patches based on bsdiff) and supports rolling back to the previous version in case of failure upon launching a new version.<\/p>\n
