Optional Deno step

Deno is not required and does nothing unless configured. It exists so a Deno build or asset step can run before the main application build, and it is configured through the environment rather than inputs — which means a job can enable it without the action’s signature changing.

Precedence: environment > inputs > defaults. With nothing set, Deno is skipped.

Variable	Meaning
DENO_ENABLE	true/1/yes/on — enable even without a build command.
DENO_BUILD	The command to run, e.g. deno task build.
DENO_VERSION	e.g. v1.44.x.
DENO_WORKDIR	Working directory. Defaults to ..

Pass-throughs when present: DENO_AUTH_TOKEN, DENO_DIR, HTTP_PROXY, HTTPS_PROXY, NO_PROXY.

Job-level

jobs:
  build:
    runs-on: ubuntu-latest
    env:
      DENO_VERSION: 'v1.44.x'
      DENO_WORKDIR: 'frontend'
      DENO_BUILD: 'deno task build'
    steps:
      - uses: actions/checkout@v7
      - uses: dAppCore/build@v4
        with:
          build-name: myApp

From a previous step

- run: |
    echo "DENO_ENABLE=true" >> "$GITHUB_ENV"
    echo "DENO_BUILD=deno task build" >> "$GITHUB_ENV"
- uses: dAppCore/build@v4
  with:
    build-name: myApp
