Deno 2.0 released with full Node.js compatibility and enhanced JavaScript development

Deno 2.0 has been released, marking a major update to the Deno runtime, which focuses on JavaScript, TypeScript, and WebAssembly. This new version introduces full compatibility with Node.js, allowing developers to run Node.js projects in Deno without modifications while utilizing npm packages, positioning Deno as a viable alternative for those looking to transition to its modern features without disrupting their existing workflows.

The update also enhances JavaScript development with zero-configuration tooling and native TypeScript support, improving both scalability and efficiency. The standard library in Deno 2.0 is now stable, providing a reliable set of audited utility modules for various development tasks, minimizing the need for external dependencies.

The update introduces key improvements in package management, including the deno install command for managing dependencies, and deno add and deno remove for adjusting package files. It also supports private NPM registries, workspaces, and monorepos. Enhanced tools like deno fmt, deno lint, and deno coverage streamline the development process, with deno fmt supporting additional file types, deno lint including Node-specific rules, and coverage reports now available in HTML format. Additionally, starting with Deno 2.1, a Long-Term Support (LTS) release channel will provide six months of critical bug fixes for stable production use, with new LTS branches released periodically.
