CI and GitHub Actions

Deno Deploy's Git integration enables deployment of code changes that are pushed to a GitHub repository. Commits on the production branch will be deployed as a production deployment. Commits on all other branches will be deployed as a preview deployment.

There are two modes of operation for the Git integration:

1. Select your organization name, and repository. If your repository or organization does not show up, make sure the Deno Deploy GitHub App is installed on your repository.
2. Select a production branch. Code deployed from this branch will be deployed as a production deployment instead of a preview deployment.
3. Choose either Automatic or GitHub Actions deployment mode.
   • Automatic: Deno Deploy will automatically pull code and assets from your repository source every time you push, and deploy it. This mode is very fast, but does not allow for a build step. This is the recommended mode for most users.
   • GitHub Actions: In this mode, you push your code and assets to Deno Deploy from a GitHub Actions workflow. This allows you to perform a build step before deploying. Below, we go into more detail about the different configurations for Automatic and Github Actions mode.

Automatic

If you select Automatic mode above, you'll subsequently have to select a file in your Github repo as the "entrypoint" file. The entry file is simply the file that Deno will run.

GitHub Action

GitHub Action mode enables you to add a build step to your deployment process by leveraging the deployctl Github action:

1. Navigate to <project-name> project page and select your Github repo under the Git integration card.

   

2. Select your branch for the production branch, and in the popup that appears, select Github Action

   

3. Click Ok

   

4. Click Link

   

5. This should take you to a next page, where you see a preview of a deploy.yml file that you can download. Download the file and add it to your Github project under .github/workflows/deploy.yml

   

6. Modify the deploy.yml file as appropriate with your build step, Deno project name, and entrypoint file:

   job:
   permissions:
       id-token: write # This is required to allow the GitHub Action to authenticate with Deno Deploy.
       contents: read
   steps:
       - name: Deploy to Deno Deploy
       uses: denoland/deployctl@v1
       with:
           project: my-project # the name of the project on Deno Deploy
           entrypoint: main.ts # the entrypoint to deploy

   By default the entire contents of the repository will be deployed. This can be changed by specifying the root option.

   - name: Deploy to Deno Deploy
   uses: denoland/deployctl@v1
   with:
       project: my-project
       entrypoint: index.js
       root: dist

   The entrypoint can either be a relative path, file name, or an absolute URL. If it is a relative path, it will be resolved relative to the root. Both absolute file:/// and https:// URLs are supported.

   To deploy the ./dist directory using the std/http/file_server.ts module, you can use the following configuration:

   - name: Deploy to Deno Deploy
   uses: denoland/deployctl@v1
   with:
       project: my-project
       entrypoint: https://deno.land/std@0.202.0/http/file_server.ts
       root: dist
