😎 WebApp made simple 🎉

Simple WebApp (SPA) using esbuild, jsx-dom and tailwindcss

📑 Requirements

• NodeJS for developing the webapp
• Docker for building the image
• kubectl for deploying to Kubernetes

🏗️ Structure

All source-files for the app resides in the ./src folder.

Where the ./src/main/app.jsx file is your main entry point for your app which gets bundled via esbuild. Any custom css goes into the ./src/main/app.css file and any static resources (e.g. html, images, etc.) goes into the ./src/resource folder.

There is also a ./src/kubernetes/app.ts file, which gets compiled to a Kubernetes manifest YAML file.

That's all! 😉

💻 Development

To bundle the app in ./src/main/app.tsx just run make or following commands

npm install
node build.mjs

This produces all files for the browser inside the out folder.

If you want to enable live-reload, just run make serve or

node build.mjs serve

🐋 Docker

🐋 Build 🛠️

Just run make docker_build or following commands

docker build -t ${NAME}:latest .

Docker image size is ~112 kB! 🤯

🐋 Run

Just run make docker_run or following command

docker run --name ${NAME} -dt --rm --init -p ${PORT}:3000 ${NAME}:latest

Alternatively, you can also use docker compose up to start the container, by using the ./docker-compose.yaml.

🐋 Stop

Just run make docker_stop or following command

docker container stop ${NAME}

Or use docker compose stop to stop the container, when using the ./docker-compose.yaml.

🐋 Cleanup 🧹

Just run make docker_clean or following command

docker image prune

☸️ Kubernetes

☸️ Build 🛠️

To bundle the kubernetes manifest in ./src/kubernetes/app.ts just run make k8s or following commands

npm install
node build.mjs k8s

This produces the yaml kubernetes manifest file inside the out folder.

☸️ Apply via kubectl

Just run make k8s_apply namespace=dev-test ('namespace' is optional) or following command

kubectl apply -f out/${NAME}.k8s.yaml --namespace $(namespace)

☸️ Delete via kubectl

Just run make k8s_delete namespace=dev-test ('namespace' is optional) or following command

kubectl delete -f out/${NAME}.k8s.yaml --namespace $(namespace)

⚙️ Github Release + Package

Whenever a new commit is pushed on the main branch or a pull request is created, the Github workflow gets triggered. The workflow (./.github/workflows/buildAndRelease.yaml) builds the app, Docker image and Kubernetes manifest.

To create a Github Release and publish the app, Docker image and Kubernetes manifest, you only have to tag the specific commit with *.*.* notation (SemanticVersion).

Just run make release version=1.0.0 or following commands

git tag v1.0
git push origin tag v1.0

It is also possible to delete a release. Just run make release_delete version=1.0.0 or following commands

git tag -d v1.0
git push --delete origin v1.0
