On June 18, the Trademark Trial and Appeal Board (TTAB) dismissed our fraud claim against Oracle. We disagree with this decision. That claim alleged Oracle knowingly misled the USPTO in its 2019 renewal by submitting a screenshot of the Node.js website to show use of the “JavaScript” trademark. As the creator of Node.js, I find that especially offensive. Node.js was never an Oracle product or bran

There’s been some criticism lately about Deno - about Deploy, KV, Fresh, and our momentum in general. You may have seen some of the criticism online; it’s made the rounds in the usual places, and attracted a fair amount of attention. Some of that criticism is valid. In fact, I think it’s fair to say we’ve had a hand in causing some amount of fear and uncertainty by being too quiet about what we’re

Fresh is a simple web framework based on the latest web standards that we built and use quite heavily here at Deno. We’ve teased the next version for quite some time now, but haven’t yet cut a release. Rest assured we haven’t forgotten about it. In fact, a pre-release version of Fresh 2 is being used in production here at Deno — on our main website as well as on Deno Deploy. Whenever we post an up

Deno has always been committed to web standards and runtime interoperability. Here at Deno, we believe that the web is the most important development platform in the world - poised to outlive all other development platforms. We believe that the APIs that make up the web are so ubiquitous that they should not be constrained to just the browser. They should be usable by any developer, including serv

On November 22, 2024, Deno formally filed a petition with the USPTO to cancel Oracle’s trademark for “JavaScript.” This marks a pivotal step toward freeing “JavaScript” from legal entanglements and recognizing it as a shared public good. If successful, the petition will eliminate barriers that have stifled community use of the name. Conferences could reclaim titles like “JavaScript Conference” ins

Astro is a modern web framework focused on content-centric websites, which leverages islands architecture and sends zero JavaScript to the client by default. And with the recent release of Deno 2, now backwards compatible with Node and npm, the experience of using Astro and Deno has improved. Deno 2 is backwards compatible with Node and npm, allowing you to use your preferred JavaScript framework.

ECMAScript modules (”ESM”) are the official, modern way of writing and sharing JavaScript — it’s supported in many environments (e.g. browsers, the edge, and modern runtimes like Deno), and offers a better development experience (e.g. async loading and being able to export without globals). While CommonJS was the standard for many years, supporting CommonJS today is hurting the JavaScript communit

Watch our video announcement. Announcing Deno 2 The web is humanity’s largest software platform — building for it means potentially reaching over 5 billion people. But as web development has accelerated in recent years, it has also become increasingly and unmanageably complex. Before writing a single line of code, developers must deal with tedious configuration and wading through unnecessary boile

Deno is a modern, zero-config JavaScript runtime written in Rust. At its core is Rusty V8, a library that provides high-quality, zero-overhead Rust bindings to V8’s C++ API. Over the past five years, Rusty V8 has undergone nearly 150 releases, racking up more than 3.1 million downloads on crates.io. Today, we’re excited to announce a major milestone: Rusty V8 is now stable and production-ready. Wh

UPDATE 2024/10/04: We’ve released several updates to the Deno 2.0 Release Candidate. We’ve been planning a new major version of Deno for years. Many times, it seemed imminent, but we realized the features we wanted required more work. Now, it’s finally happening. Last month, we released the final 1.x version with 1.46, and today, we’re cutting the release candidate for Deno 2.0, which includes eve

We built Deno, a modern, simple, secure, zero-config JavaScript (and TypeScript) runtime, to radically simplify web development, and performance is a critical pillar of that mission. In our benchmarking, we found that running Deno in AWS Lambda consistently has the lowest cold start time compared to other JavaScript runtimes. In this post, we’ll share our methodologies for running said benchmarks,

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.

Programming should be simple, which is why we built Deno to be “batteries included” with all-in-one tooling, native TypeScript support, and web standards APIs. (You can get started with TypeScript just by naming a file with a .ts extension.) One major way Deno boosts productivity is through our language server, which offers auto-completion, tooltips, linting, code formatting, and more. Recently, a

Over the past years, new package managers like yarn and pnpm have emerged, enhancing how packages are downloaded. However, the npm package registry, a cornerstone of the JavaScript ecosystem, has barely evolved. Its last notable update was a “files” tab added years ago. The JavaScript language, known for its vibrant evolution, seems paradoxically mired in a distribution model that hasn’t kept pace

JSR is a modern JavaScript registry intended to simplify publishing and consuming JavaScript and TypeScript modules, while also moving the ecosystem forward by supporting and promoting web standards. Since our launch, over 7.5k users have signed up to JSR. Today, we’re thrilled to announce that the Neon Serverless Driver is now available on JSR. Neon is a fully managed, serverless, scalable Postgr

JavaScript is constantly evolving, from its roots as a simple scripting language into a robust, modern tool for building complex applications. To manage larger, complicated code bases, JavaScript developers are constantly looking for ways to improve their workflows, their code quality and productivity. TypeScript is a major innovation towards improving code quality and maintenance by adding types,

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

Many backend engineers prefer to manage infrastructure and deployments through a command line interface, especially when building CI/CD scripts where settings and configurations can all be represented through flags and code. Managing your projects on Deno Deploy is no exception — with deployctl you can now manage the whole lifecycle of your deployments without ever leaving the terminal. This blog

In 2023, Deno shifted into high gear with respect to Node/npm compatibility and performance work, while continuing to move towards our goal of radically simplifying web development. Here’s a summary of what changed in 2023: Deno now understands package.json files and has the ability to import built-in Node modules using node: specifiers like node:fs and node:crypto. Read more.
