In the Creact React App setup the, when you run yarn build, a build/ directory is generated.
I this directory there's a static directory/.
If, in your setup it's an other directory you can use this option:
{% code title="package.json" %}
{
"keycloakify": {
"staticDirPathInProjectBuildDirPath": "a/b/c"
}
}
{% endcode %}
By default it's "static"
.
