Applications

Applications are web services that serve traffic within an organization. Each application contains a history of revisions (previous versions), typically corresponding to Git commits when using the GitHub integration.

Applications are identified by a slug, which must be unique within the organization and is used in default domain names.

Creating an application Jump to heading#

To create an application:

1. Click the "+ Create App" button on the organization page
2. Select the GitHub repository to deploy from
3. Configure the app slug (name)
4. Set up build configuration
5. Add any required environment variables

⚠️ Currently, applications must be linked to a GitHub repository during creation.

The build configuration determines how the application is built during the deployment process. Builds are automatically triggered on each push to the linked repository or when manually clicking "Deploy Default Branch". For detailed build configuration information, see the Builds documentation.

You can add environment variables during app creation by clicking "Edit Environment Variables". For more details on environment variables, see the Environment Variables and Contexts documentation.

Renaming an application Jump to heading#

Applications can be renamed by editing the app slug on the app settings page. This will update the default domain names associated with the app since they are based on the app slug. The new slug must be unique within the organization (i.e. must not be in use by another app or playground in the same organization).

:::warning

Any previous deno.net URLs pointing to the app will no longer work after renaming.

Custom domains will continue to work, as they are not tied to the app slug.

Deleting an application Jump to heading#

Applications can be deleted from the app settings page. This will remove the app and all its revisions from the organization. All existing deployments will immediately stop serving traffic, and all custom domain associations will be removed.

The app and its revisions will no longer be accessible after deletion, and no traffic will be served from it. Deleted apps cannot be restored through the Deno Deploy UI.

Limitations Jump to heading#

⚠️ Apps cannot currently be transferred to another organization.

GitHub integration Jump to heading#

The GitHub integration enables automatic deployments of the app from a GitHub repository. Every push to the repository will trigger a new build of the app. Depending on the branch of the commit, the build will be deployed to different timelines.

Apps are linked to a GitHub repository during creation. However, it is possible to unlink the repository after creation, and optionally link it to a new GitHub repository. This can be done from the app settings page.

Only accounts that have been authorized with the Deno Deploy GitHub app will be visible in the GitHub repository dropdown. You can authorize new organizations or repositories by clicking the "+ Add another GitHub account" button in the user or organization dropdown, or the "Configure GitHub app permissions" button in the repository dropdown. This will redirect you to GitHub to authorize the Deno Deploy GitHub app with the selected GitHub account or organization. After authorization, you will be redirected back to the app settings page, where you can select the newly authorized GitHub repository.
