Deno 1.46: The Last 1.x Release
These shorthand flags accept allow lists just like the long versions - eg. -R=./static, -E=DEBUG,LOG, -N=deno.com. If you don’t want to provide allow lists you can combine them together - eg. -RWN will enable read, write and net permissions. Here’s a couple examples how you can shorten your CLI invocations: # Deno v1.45 deno run --allow-read=./static --allow-env --allow-net=myapi.example.com main.
What we got wrong about HTTP imports
Everything should be made as simple as possible, but not simpler. Albert Einstein From the beginning, HTTP imports have been a key feature of Deno. For years, this was the entire module system, aimed at simplifying JavaScript development by using the web’s distributed nature, unlike npm’s centralized registry. For example, you can import the assertEquals() function from the standard library like t

How we built JSR
We recently launched the JavaScript Registry - JSR. It’s a new registry for JavaScript and TypeScript designed to offer a significantly better experience than npm for both package authors and users: It natively supports publishing TypeScript source code, which is used to auto-generate documentation for your package It’s secure-by-default, supporting token-less publishing from GitHub Actions and pa
Deno 1.42: Better dependency management with JSR
Our vision with Deno is to simplify programming, and one important aspect of that is managing dependencies. While npm has grown to be the most successful open source registry, consuming and publishing modules there has grown increasingly complex. Built on npm’s success, JSR offers a modern, TypeScript-first, and cross-platform-compatible registry, fully integrated into Deno. Deno v1.42 provides mo

Deno KV internals: building a database for the modern web
Deno is designed to streamline web and cloud development with built-in modern tools, direct access to web platform APIs, and the capability to import modules via npm. Web apps very often require some persistent application state. Setting up a database involves numerous configuration steps and the subsequent integration of an ORM or other systems. What if you could access such a database without an
