Features Jump to heading

  • New: Database support for Deno DeployEA apps, allowing you to easily connect to and use Postgres databases in your applications.
    • Provision a Postgres database instance on AWS RDS, Neon, Supabase, or any other provider and then link it to your Deno DeployEA organization.
    • Assign the database instance to an application, making it available in the application's environment.
    • Every timeline (production, each git branch, and previews) has their own isolated database with a separate schema and data, allowing you to test migrations and changes without affecting production data.
    • Use any Postgres client library to connect, including npm:pg, npm:drizzle, or npm:kysely.
  • Applications and playgrounds can now be renamed. Note, old deno.net URLs will no longer work after renaming, but custom domains will continue to function.
  • Applications and playgrounds can now be deleted.
  • Playgrounds now have an HTTP Explorer tab that allows you to make arbitrary HTTP requests to any URL served by the playground. This is useful for testing APIs or other services that do not serve a web page.
  • You can now delete entire folders in the playground file explorer by pressing the delete button next to the folder name.
  • You can now drag a zip file onto the playground file explorer to upload all files in the zip file to the playground.
  • You can now enable auto-format on save in the playground, which will automatically format your code when you save a file.

Bug fixes Jump to heading

  • DENO_ prefixed environment variables such as DENO_CONDITIONS, DENO_COMPAT, and DENO_AUTH_TOKENS can now be set without error.
  • The DENO_REVISION_ID environment variable is now correctly exposed to applications and playgrounds.
  • The custom domain assignment drawer now shows custom domains that are already assigned to another application or playground as disabled.
  • The network usage graph on the metrics page now correctly shows incoming and outgoing traffic. Previously, the data shown was incorrect.
  • For newly created organizations the first build now waits until the <org>.deno.net domain is provisioned before the routing step.
  • Pressing Ctrl-S / Cmd-S in the playground now saves the current file and triggers a build, instead of opening the browser's save dialog.
  • Viewing some specific traces previously hung the trace viewer. These now show correctly.

Features Jump to heading

  • New: Cloud Connect allows you to securely connect your Deno DeployEA apps to AWS and GCP, enabling you to use services like AWS S3, Google Cloud Storage, without needing to manage credentials.
    • This is done without storing any long-lived static credentials, but rather using short-lived tokens and OIDC (OpenID Connect) to establish a trust relationship between Deno DeployEA and your cloud provider.
    • A setup flow in the app settings page, or a drawer in playgrounds, guides you through the process of connecting your app to AWS or GCP.
    • You can use the standard AWS and GCP SDKs to access the services - no need to re-write any code to use a different API.
    • Learn more in the documentation.
  • The application metrics page now shows more metrics, including V8 memory metrics such as heap size and garbage collection stats, as well as process level metrics such as CPU usage and overall memory usage.
  • There is now a new "Metrics" tab in the organization overview that shows overall metrics for all applications in the organization, including the number of requests, CPU usage, and memory usage.
  • You can now edit the URL you are viewing in the playground preview iframe by editing the "address bar" that is displayed above the preview.
  • Environment variables now default to being a secret when the key contains SECRET, KEY, TOKEN, PRIVATE, or PASSWORD. You can still manually switch them to plain text if needed.
  • The maximum length limit for environment variable values has been increased to 4096 characters, up from 1024 characters.

Bug fixes Jump to heading

  • Playgrounds do not get stuck when attempting to deploy an empty file anymore.
  • Playground drawer resizing now works more reliably, especially when some drawers are collapsed.
  • Builds now take significantly less time to complete, especially for larger projects. The "Warmup" and "Routing" steps, which previously took more than 10 seconds respectively, now usually take less than 1 second each.
  • Builds can now be cancelled while they are in the "Queueing" and "Routing" steps.
  • The organization creation page now correctly displays whether an organization slug is taken or not, prior to submitting the form.
  • npm install can now install esbuild again - previously it would fail with a generic error.
