JavaScript, the undisputed king of web development, is being sabotaged — not by a rival language or a revolutionary new technology, but by its own baggage from the past. This insidious saboteur is none other than CommonJS, the antique module system that we’ve tolerated for far too long. The rise of CommonJSAbout 15 years after its invention, JavaScript started expanding beyond the browser to the s

We’re excited to announce that starting today, Deno Deploy supports importing Node.js built-in modules such as http, fs, and path. You can now run existing Node.js apps at the edge. Deno Deploy is a next-generation cloud platform built on JavaScript isolates. It runs your JavaScript, TypeScript, and WebAssembly at the edge, in our 35 global regions, close to your users. It scales automatically, fr

As we continue our development journey towards Deno 2, this minor release is primarily focused on boosting compatibility with npm and Node.js, enhancing the overall quality of life and developer experience, and establishing the foundation for future performance enhancements. The most significant updates in this release include three highly anticipated features: deno compile supports npm packages G

We’re thrilled to introduce Deno KV, a strongly consistent key-value database, globally replicated for low-latency reads across 35 worldwide regions. Deno Deploy aims to provide the simplest and fastest way to deploy and run JavaScript, TypeScript, and Wasm at the edge. However, creating stateful apps on Deno Deploy previously required connecting to external cloud databases, which involved additio

As mentioned in the recent “Forced Optimization” presentation at Node Congress 2023, we’re working diligently towards a major release of Deno 2 in the coming months. Though our vision for Deno 2 is ambitious, our goals haven’t changed since we started the project: Effortless Coding: Whether that’s removing config, boilerplate code, or build steps, we’ve continued to make it easy for you to dive in

Read your data in milliseconds, worldwide. Enjoy seamless data consistency with ACID transactions. Develop and test locally using Deno CLI, where KV is built right in. Open a KV store in any Deno program with one line of code. It doesn't matter whether your code runs locally, or in any of our data centers around the world. Deno KV works anywhere, with zero setup and zero provisioning.

Support for built-in Node.js modulesIn Deno, npm packages have already had access to built-in Node.js modules such as fs, path, process, and many more through Deno’s Node.js compatibility layer.

Deno in 2022: npm, Edge Functions, Series A, Fresh, and more 2022 was a big year for Deno! We: have over 250k monthly active users stabilized npm compatibility, which will be an integral part of Deno going forward (more on that below) have been downloaded over 5 million times launched Fresh, a Deno- and edge-first framework that embraces modern web principles partnered with Netlify and Supabase to

TLDR: We’ve been working on some updates that will allow Deno to easily import npm packages and make the vast majority of npm packages work in Deno within the next three months. Our goal is to make Deno the fastest JavaScript runtime. For starters, the next release of Deno will include a new HTTP server. It is the fastest JavaScript web server ever built. Given the extensive use of Deno by develop

Fresh is a new full stack web framework for Deno. By default, web pages built with Fresh send zero JavaScript to the client. The framework has no build step which allows for an order of magnitude improvement in deployment times. Today we are releasing the first stable version of Fresh. Client side rendering has become increasingly popular in recent years. React (and React-like) pages allow program

Have you ever wondered how web compatible Deno is? Probably not, but I did today. To answer that question, I am writing this blog post: I’ll list and explain every single web API implemented in Deno. Get yourself something to drink, because this is going to take a while to go through. Before we get into it though, I just want to set some ground rules: I am not including any JS language features. O

Deno aims to be the best runtime for the modern JavaScript developer. One way we do this is by embracing the latest in JavaScript standards. Deno is fundamentally built for modern JavaScript: Promises, async/await, ES modules and async iterators are all first-class citizens. To make sure that future evolutions of JavaScript will continue to work well for Deno - and server-side JavaScript runtimes

Today Slack has announced their next generation development platform. Slack chose Deno for its “secure by default” principles, its web standard APIs, and its first-class TypeScript support. Read more about it at https://api.slack.com/future. We’ll be collaborating with Slack to improve and polish this new platform in the coming months. We hope you will give it a try and we look forward to hearing

Deno embraces modern web APIs. When capabilities are added to the runtime, the preference is in the form of a browser API. This benefits developers because they are already familiar with these APIs, and it benefits Deno because already existing tests can be leveraged. Web APIs have a huge amount of documentation. Searching for “fetch javascript” turns up hundreds of millions of results. The best s

Of the myriad ways to program computers, scripting languages are the most effortless and practical variety. Of these, the web browser scripting language (JavaScript) is the fastest, most popular, and the only one with an industrial standardization process. It is clear that the web will be with us for a long time to come; and thus JavaScript will be with us for a long time to come. Extending web pr
