We’re excited to announce that Deno 1.28 stabilizes npm compatibility, which means you can now import over 1.3 million npm modules in Deno. Building apps will be easier and more secure than ever, now that you can use your favorite persistent data modules such as Prisma, Mongoose, and MySQL, as well as frontend frameworks such as React, Vue, etc. Using npm is easier and safer with Deno. Deno’s buil

WordPress is the most successful content management system (CMS), powering 65.2% of CMS-based websites and 43.2% of all websites (on the internet) in 2022—and continues to grow. But building on WordPress comes with some challenges. You can either modify an available theme based off old technologies (e.g. jQuery) or spend time setting up WordPress’s REST API (“headless” mode) with a modern web fram

Authentication and session management are one of the most fundamental aspects of building a modern web app. It’s necessary for hiding premium content or creating admin-only sections like dashboards. Fresh is an edge-native web framework that embraces progressive enhancement through server-side rendering and islands architecture, while optimizing for latency and performance. As a result, Fresh apps

Language Server/IDE improvementsInlay HintsTypeScript added support for inlay hints in version 4.4; this release of Deno exposes this functionality to the LSP.

Fresh is an edge-first web framework that delivers zero JavaScript to the client by default with no build step. It’s optimized for speed and, when hosted on the edge with Deno Deploy, can be fairly trivial to get a perfect Lighthouse pagespeed score. This post will show you how to build your own markdown blog with Fresh and deploy it to the edge with Deno Deploy. View source here. Create a new Fre

Which serverless edge platform has the fastest git deployments? Deploying to the edge is becoming more common, with multiple services that offer serverless edge computing. One of the most important factors is speed of deployment, since context switching and waiting for code to build and deploy can halt momentum, flow state, and developer productivity. So, which serverless edge compute platform han

Except Singapore, we’ve got a world of sub-100 millisecond TTFBs. This is because instead of heading off to Virginia to get the site, each of these locations can use an edge server nearest to them. The edge is about getting 50ms response times vs 150ms response times. You can test this for yourself with a VPN. If you: curl -I https://deno.landYou’ll get the server nearest your location: server: de

Cache Web APIWe added support for the Cache API in this release. The API allows you to cache Request/Response objects. This is helpful when you dynamically generate responses. It allows you to cache a response for a GET

If you’ve ever tried Deno Deploy, our multi-tenant distributed JavaScript cloud, you may understand some of these glowing reviews: (And if you haven’t, deploy a Fresh site today!) Achieving this deployment speed was no mistake. Designing Deno Deploy was an opportunity to re-imagine how we want the developer experience of deploying an app to be, and we wanted to focus on speed and security. Instead

This is a guest blog written by Jim Ray, Director of Developer Advocacy at Slack. Seven years ago, we launched the Slack Platform for the first time, inviting developers to bring their favorite tools into Slack, where they’re already working everyday. A lot has changed since then — we’re now in a serverless era, plus developers have more pressure than ever to build fast while also staying nimble i

A Whole Website in a Single JavaScript File, cont'd Back in April, we published “A Whole Website in a Single JavaScript File”. However, based on some comments, we realized we didn’t fully communicate what we felt was unique about such an exercise — its simplicity and performance without sacrificing functionality users expect from modern websites. So this is a follow up blog post and a new playgrou

Fresh 1.1 - automatic JSX, plugins, DevTools, and more 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 development experience and deployment times. Today we are releasing the next significant version of Fresh.

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

In this post we’ll walk through creating a custom JavaScript runtime. Let’s call it runjs. Think of it as building a (much) simplified version of deno itself. A goal of this post is to create a CLI that can execute local JavaScript files, read a file, write a file, remove a file and has simplified console API. Let’s get started. Update 2022-12-04: updated the code samples to the latest version of

When writing JavaScript, it’s sometimes useful to call into Rust code. For example, there might be a complex algorithm already implemented in Rust that you want to reuse, or some Rust code might run faster and be more memory efficient than any JS implementation. This blog post introduces a new tool called wasmbuild, which simplifies the process of building and using Rust code in Deno and the brows
