Run using Docker:

With Docker, you can run DenCode wherever you want.

docker run -p 8080:8080 ghcr.io/mozq/dencode:latest

After startup, DenCode can be accessed at http://localhost:8080/ .

Build using Gradle:

If you want to build DenCode from the source code yourself, use Gradle within the project. Install Java SE Development Kit (JDK) and run the following command on the project root directory. Build artifacts are stored in build/app/ directory.

./gradlew build

If you want to run DenCode as well, run the following command.

./gradlew runApp

Deploy to Google App Engine:

Install Google Cloud SDK and run the following commands. First two commands, gcloud auth and gcloud config, only need to be run for the first time.

gcloud auth login
gcloud config set project {PROJECT_ID}

./gradlew build
cp src/main/appengine/app.yaml build/app/
gcloud app deploy build/app/app.yaml --no-promote --no-stop-previous-version

(Please replace {PROJECT_ID} with your own project ID.)
