A high severity Denial-of-Service (DoS) vulnerability has been found in React Server Components and Next.js. Deno has implemented mitigations in Deno Deploy. Immediate upgrades are required for other users.

This series of posts will guide you through building a simple game using Deno. Each post corresponds to a stage in the development process, gradually introducing new features and concepts.

A critical Remote Code Execution (RCE) vulnerability has been found in React Server Functions and Next.js. Deno has implemented mitigations in Deno Deploy. Immediate upgrades are required for other users.

Highlights from the new version of Deno Deploy.

Addressing recent Deno criticisms and sharing our vision for the future

Here's how to get your Next.js SSR project up and running on Deno Deploy.

The Web Cache API offers sub-millisecond read latency, multi-Gbps write throughput, and unbounded storage. Here’s how you can use it.

You can now exercise greater control over your Deno Deploy spend with our new spend limits. Here’s how they work.

When building a modern cloud platform to securely run untrusted code, it can be difficult to balance cost and performance. Here’s how we built Deno Deploy and Deno Subhosting.

Introducing a more simplified project creation flow in Deno Deploy, including seamless CI/CD setup, a more transparent build and deployment step, and more.

Deno Deploy’s command line interface, deployctl, is the simplest way to deploy your projects to the cloud. Here’s how to do it.

We revamped Deno Deploy’s onboarding to show you how easy it is to use Deno’s cloud primitives in your projects.

We compare Deno KV to other serverless data stores on performance, price, developer experience, and more.

Access our zero config distributed database, Deno KV, in your Node projects with our new npm package.

Detecting changes in Deno KV with `kv.watch` makes it easier to build real-time applications like newsfeeds, analytics, multi-user collaboration tools, and more.

Terraform is a popular tool used to safely and predictably provision and manage infrastructure in any cloud. Here’s how you could use Terraform to manage your Deno Deploy or Deno Subhosting projects.

`Deno.cron` allows you to easily create scheduled jobs and is available on Deno Deploy. Here's how it works.

Deno Deploy and Deno Subhosting was designed with security and tenant isolation in mind. Here's how it works.

Subhosting is a new way to leverage Deno Deploy's fast, scalable multi-tenant v8 isolate cloud to run your users code securely.

Deno KV is now even more flexible and powerful with self-hosted options, replicas, and S3 and GCS continuous backup support.

Introducing Deno Queues - zero config, scalable messaging with a guaranteed at-least-once delivery. This new primitive builds on the foundation set by Deno KV, and is available today in the Deno JavaScript runtime and Deno Deploy.

With npm compatibility in Deno improving, and npm specifiers now available on Deno Deploy, there are more options than ever to build web apps on Deno. Let's explore some options, including Fresh, SvelteKit, Nuxt/Vue, Astro, and beyond.

How we built a performant, scalable, ACID-compliant, JavaScript-native database on FoundationDB.

Deno Deploy becomes the first isolate serverless platform to natively support more than two million modules on npm.

Deno KV, the easiest way to add a strongly consistent database to your app, is now in open beta.
