Breaking Down the New Features in Deno 2
When Deno first came out, it shook up the JavaScript and TypeScript world with some fresh ideas. It was created by Ryan Dahl, the same guy who made Node.js, and Deno was meant to solve some of Node’s issues, like security and how modules work. Now, Deno 2 is here and it’s got even more features and improvements, making it a powerful choice for backend development.
Deno 2 brings tons of updates to make development easier, faster, and more secure. Here are some of the key improvements:
Backwards-Compatible and Future-Ready
Deno 2 works smoothly with Node and npm, meaning you can use it alongside your current Node projects. For example, after cloning a Node project, you can use deno install to quickly set up dependencies or deno fmt to format your code without needing Prettier.
Deno 2 handles package.json, node_modules, and npm workspaces, so it can run in any Node project using ESM. For minor syntax issues, just use deno lint --fix.
If you don’t like package.json and node_modules but still want to use npm packages, you can import them directly using npm: specifiers. This lets you write programs with npm dependencies in a single file—no extra configuration is needed.
