m8a scenario #1 - Using Coder to Develop Keycloak Templates Live (almost)...
Getting back to our two main technologies....we have implemented Keycloak as our Identification and Authorization Management system (IAM). However, as these things go, Keycloak has its own tech stack. One of the technologies, of course, is the language they used, which is Java. And being it is Java, they chose to use a templating engine called Freemarker.

Typescript, Webpack and legacy jquery with plugins
The project I was working on was a website using Magnolia as their CMS. It uses the Freemarker templating engine under the hood. Essentially these are super-powered HTML files, which give you access to the CMS content. You can still use all of the HTML tags you want, including the

Can I use Java to build a website?
You can use Java for Backend and Frontend. A relative new kid on the block for Frontend is Qute. The general keyword you are searching for is Java Templating Engine. Specific examples would be Thymeleaf or FreeMarker. There are some framework, which offer a lot more than templating like Vaadin or Wicket. Some are just specifications like Jakarta Faces with some of their implementations MyFaces or Mojarra.

Simplifying Keycloak Configuration with Terraform and Terragrunt
Keycloak, an open-source identity and access management solution, provides robust authentication and authorization services for modern applications. However, configuring Keycloak instances manually can be tedious and error-prone. In this blog post, we'll explore how to simplify Keycloak configuration using Terraform and Terragrunt, enabling infrastructure as code (IaC) practices for managing Keycloak realms, clients, users, and more.

What Is OIDC?
> Don't outsource either your authentication or authorization. Run it in-house.
This is hard to do, though. I hope people here will drop a lot of combinations that work for them!
Personally, for a small/medium scale project, I went with:
Keycloak: https://www.keycloak.org/
It supports various backing RDBMSes (like PostgreSQL, MariaDB/MySQL and others), allows both users that you persist in your own DB, as well as various external sources, like social login across various platforms, is an absolute pain to configure and sometimes acts in stupid ways behind a reverse proxy, but has most of the features that you might ever want, which sadly comes coupled with some complexity and an enterprise feeling.
I quite like that it offers the login/registration views that you need with redirects, as well as user management, storing roles/permissions and other custom attributes. It's on par with what you'd expect and should serve you nicely.
mod_auth_openidc: https://github.com/OpenIDC/mod_auth_openidc
This one's a certified OpenID Connect Relying Party implementation for... Apache2/httpd.
Some might worry about the performance and there are other options out there (like a module for OpenResty, which is built on top of Nginx), but when coupled with mod_md Apache makes for a great reverse proxy/ingress for my personal needs.
The benefit here is that I don't need 10 different implementations for each service/back end language that's used, I can outsource the heavy lifting to mod_auth_openidc (protected paths, needed roles/permissions, redirect URLs, token renewal and other things) and just read a few trusted headers behind the reverse proxy if further checks are needed, which is easy in all technologies.
That said, the configuration there is also hard and annoying to do, as is working with OpenID Connect in general, even though you can kind of understand why that complexity is inherent. Here's a link with some certified implementations, by the way: https://openid.net/developers/certified-openid-connect-imple...
