👨‍💻👨💻 Quick start

It's a good idea to first read this quick start section to understand the basic of how Keycloakify works.

However, we recommend you start hacking from the demo setup instead of setting up Keycloakify from scratch.

Save yourself some time, have quick look at the requirements page. Windows users in particular!

yarn add keycloakify @emotion/react

package.json

"scripts": {
    "keycloak": "yarn build && build-keycloak-theme",
}

yarn keycloak # generates the keycloak-theme.jar

On the console will be printed all the instructions about how to load the generated theme in Keycloak

CSS Only customization

The first approach is to only customize the style of the default Keycloak login theme by providing your own class names.

src/index.tsx

import { KcApp, defaultKcProps, getKcContext } from "keycloakify";
//We assume the file contains: ".my-class { color: red; }"
import "./index.css";

const { kcContext } = getKcContext();

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

reactDom.render(
    <KcApp
        kcContext={kcContext}
        {...{
            ...defaultKcProps,
            "kcHeaderWrapperClass": "my-class",
        }}
    />,
    document.getElementById("root"),
);

The above snippet of code assumes you are in a react project wich only purpose is to be a Keycloak theme.

But if you want to make your keycloak theme an integral part of a preexisting React app you would apply the following modification to the above snipet:

+import { App } from "<you know where";
 import { KcApp, defaultKcProps, getKcContext } from "keycloakify";
 import "./index.css";

 const { kcContext } = getKcContext();

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

 reactDom.render(
+    kcContext === undefined ?
+        <App /> :
         <KcApp
             kcContext={kcContext}
             {...{
                 ...defaultKcProps,
                 "kcHeaderWrapperClass": myClassName,
             }}
         />,
     document.getElementById("root"),
);

Result: MYREALM is red

Real world example

To give you an idea of what you can already achieve by only customizing the style the style,

Here is the code that produces:

Results obtained with CSS only customization of the default theme

The keycloakify components are a plain React translation of the default theme that comes with Keycloak v11.0.3.

You can download the FTL/CSS source files the components are based on with the following command:

npx -p keycloakify download-builtin-keycloak-theme

then select version 11.0.3 (Video demo).
