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

Subhosting makes it easy to securely run untrusted JavaScript from multiple customers in a secure, hosted sandbox. There are many use cases for Subhosting, such as offering their users edge functions, hosting ecommerce storefronts close to users, and more - all without worrying about security and maintaining production infrastructure. When hosting your users’ code, you sometimes want their deploym

Deno 1.44: Private npm registries, improved Node.js compat, and performance boosts Deno 1.44 introduces support for private npm registries, enabling users to use internal packages with Deno by configuring an .npmrc file. Additionally, Deno 1.44 now supports gRPC connections, enabling robust high performance communication to services like Google Cloud Platform. This release also improves Node.js co

Programming should be simple. That’s why we made Deno a zero-config, batteries-included JavaScript runtime with native TypeScript support, enabling immediate productivity. In version 1.43, we have enhanced the performance of Deno in IDEs by reducing auto-completion times from 6-8 seconds to under one second in large codebases and significantly decreasing memory usage. We have also achieved more co

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

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

Introducing deployctl, the command line interface for Deno Deploy 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

Modules are published to JSR as TypeScript source code. API documentation generation, type declarations for Node-like environments, and transpilation are all handled by JSR. Module authors can focus on writing TypeScript only. Read on for more context on how and why we built JSR, how you can use it today, and how you can be involved in the project! Introducing JSR - the slightly longer versionJava

Deno’s goal is to simplify programming in as many environments as possible. In this 1.41 release, we’re excited to announce improvements that broaden how and where Deno can be used: we’ve roughly halved the size of deno compile binaries, as well as added an official Linux ARM 64 build. Additionally, we’ve continued to improve Node.js compatibility, the LSP to include better auto-completion, and De

Webhooks are a foundational part of the web’s infrastructure. Coined in a blog post in 2007, webhooks were suggested as a simple way to consume asynchronous feeds with a protocol all web developers are familiar with — HTTP. It’s now 2024 and webhooks have more or less remained the same, yet they have become the de facto approach for not only one way notifications, but also integrating cloud system
