Deno is developed to overcome the Node.js Design Issues and provides a new modern development environment using ES6 etc.
Deno vs Node is a very hot topic for the discussion in developer and programmers community since Deno version 1.0 got released.
Let's understand both using the following key points.
Deno uses ES Modules as the default module system, whereas Node.js uses CommonJS.
Deno supports TypeScript out of the box, which means that we don’t need to manually install and configure tools to write TypeScript code.
Package Manager (NPM):
In Deno, External dependencies are loaded using URLs, similar to browsers. There is also no package manager and a centralized registry like NPM - node_modules.
In short - Deno doesn't use NPM like Node.js. Deno uses modules referenced as URLs.
Deno does not use package.json.
- Security: In Node.js application by default has permission to system calls, environment variables, accessing files, sockets, network, etc.
In Deno application you have to provide permissions to the code for system calls, environment variables, accessing files, sockets, network, etc.
- Built-in Tools: Deno also provides a set of built-in tools, like a test runner, code formatter and bundler, etc.
