A starter/demo project for Keycloakify

NOTE: If you are only looking to create a theme and don't care about integrating it into an React app there are a lot of things that you can remove from this starter. Please read this.

Quick start

yarn
yarn build-keycloak-theme # Build the theme one time (some assets will be copied to 
              # public/keycloak_static, they are needed to dev your page outside of Keycloak)
yarn start # See the Hello World app
# Uncomment line 15 of src/keycloak-theme/kcContext, reload https://localhost:3000
# You can now develop your Login pages.

# Think your theme is ready? Run
yarn build-keycloak-theme
# Read the instruction printed on the console to see how to test
# your theme on a real Keycloak instance.

Introduction

This repo constitutes an easily reusable CI setup for SPA React App that generates Keycloaks's theme using keycloakify.

The CI workflow

You need to manually allow GitHub Action to push on your REPO. For this reason the initial setup will fail. You need to enabled permission and re-run failed job: see video.
This CI is configured to both publish on GitHub Pages and on DockerHub. In practice you probably want one or the other but not both.
We deploy the demo app at starter.keycloakify.dev using GitHub page on the branch gh-pages (you have to enable it).
To configure your own domain name please refer to this documentation.
To release don't create a tag manually, the CI do it for you. Just update the package.json's version field and push.
The .jar files that bundle the Keycloak theme will be attached as an asset with every GitHub release. Example. The permalink to download the latest version is: https://github.com/USER/PROJECT/releases/latest/download/keycloak-theme.jar. For this demo repo it's here
The CI publishes the app docker image on DockerHub. <org>/<repo>:main for each commit on main, <org>/<repo>:<feature-branch-name> for each pull-request on main and when releasing a new version: <org>/<repo>:latest and <org>/<repo>:X.Y.Z See on DockerHub

If you want an example of an app that put that setup in production checkout onyxia-ui: the repo, the login, the app.

Standalone vs `--external-assets`

The CI creates two jars

keycloak-theme.jar: Generated with npx keycloakify --external-assets, the assets, located static/**/*, like for example static/js/main.<hash>.js will be downloaded from https://demo-app.keycloakify.dev/static/js/main.<hash>.js (demo-app.keycloakify.dev is specified in the package.json.
standalone-keycloak-theme.jar: Generated with npx keycloakify, this theme is fully standalone, all assets will be served by the Keycloak server, for example static/js/main.<hash>.js will be downloaded from an url like http://<your keycloak url>/resources/xxxx/login/keycloakify-starter/build/static/js/main.<hash>.js.

More info on the --external-assets build option here.

Docker

docker build -f Dockerfile -t codegouvfr/keycloakify-starter:test .
#OR (to reproduce how the image is built in the ci workflow):
yarn && yarn build && tar -cvf build.tar ./build && docker build -f Dockerfile.ci -t codegouvfr/keycloakify-starter:test . && rm build.tar

docker run -it -dp 8083:80 codegouvfr/keycloakify-starter:test

DockerHub credentials

To enables the CI to publish on DockerHub on your behalf go to repository Settings tab, then Secrets you will need to add two new secrets:

DOCKERHUB_TOKEN, you Dockerhub authorization token.
DOCKERHUB_USERNAME, Your Dockerhub username.

Standalone keycloak theme

If you are only looking to create a keycloak theme, you can run theses few commands after clicking to refactor the template and remove unnecessary file.

rm -r src/App
mv src/keycloak-theme/* src/
rm -r src/keycloak-theme

cat << EOF > src/index.tsx
import { createRoot } from "react-dom/client";
import { StrictMode } from "react";
import { kcContext } from "./kcContext";
import KcApp from "./KcApp";

if( kcContext === undefined ){
    throw new Error(
        "This app is a Keycloak theme" +
        "It isn't meant to be deployed outside of Keycloak"
    );
}

createRoot(document.getElementById("root")!).render(
    <StrictMode>
        <KcApp kcContext={kcContext} />
    </StrictMode>
);
EOF
