Drasl Web UI Customization

How far you can reskin Drasl's web frontend, and what it costs. Source repo: https://github.com/unmojang/drasl · config docs: https://github.com/unmojang/drasl/blob/master/doc/configuration.md

TL;DR

Drasl has no theme/plugin system. You get three tiers, increasing effort:

Config knobs (runtime, trivial) — rename instance, toggle footer / 3D bg.
Static-asset override (mount, easy) — swap style.css, logo.svg, icon.png.
Template / fork (build, heavy) — edit view/*.tmpl, rebuild the image.

For a "very noob-friendly UI" the realistic win is tier 2 (reskin CSS + logo) plus a dead-simple guide page on the landing site that walks guests through register → login → upload skin, screenshots included. Drasl's own pages stay the backend; the landing page is where you make it friendly.

Tier 1 — Config knobs (config.toml)

Live in drasl/config/config.toml.tmpl. Already rendered into the container at /etc/drasl/config.toml. No rebuild — just docker compose restart drasl.

Option	Default	Effect
`InstanceName`	`"Drasl"`	Site name shown in header/title. Set to `"Ulicraft Accounts"`.
`ApplicationOwner`	`"Anonymous"`	Owner label (already `"Ulicraft"`).
`EnableBackgroundEffect`	`true`	3D animated background. Off = cleaner/faster.
`EnableFooter`	`true`	Footer block.
`EnableWebFrontEnd`	`true`	Master switch for the whole web UI.

Low effort, low ceiling. Does not change layout, colors, or copy.

Tier 2 — Static-asset override (CSS + logo) ← recommended

Drasl serves static files from DataDirectory (default /usr/share/drasl). The shipped assets live in the image's public/:

style.css — primary stylesheet (all colors/spacing/theme)
logo.svg — header logo
icon.png — favicon
openid-logo.svg — OIDC button icon (unused here, no OIDC)

Plan

Pull the upstream style.css as a baseline: https://raw.githubusercontent.com/unmojang/drasl/master/public/style.css
Create drasl/public/ in this repo. Drop in your edited style.css, logo.svg, icon.png.
Bind-mount over the container's asset dir in docker-compose.yml:
```
drasl:
  volumes:
    - ./drasl/config:/etc/drasl:ro
    - ./drasl/public:/usr/share/drasl/public:ro   # <-- add
    - drasl_state:/var/lib/drasl
```
⚠ Verify the exact in-container path first — assets may sit at /usr/share/drasl/public/ or directly under /usr/share/drasl/. Check:
```
docker compose exec drasl sh -c 'find /usr/share/drasl -name style.css'
```
Mount to match whatever that prints. Mount the directory, not the single file, so the logo/icon ride along.
docker compose up -d drasl. Hard-refresh browser (CSS cache).

Ceiling: full restyle of existing pages — colors, fonts, button sizes, hide clutter, big friendly upload button. Cannot add/remove page elements or reword text (that's the templates → tier 3).

Tier 3 — Templates / fork (heavy)

Page structure + copy live in Go templates view/*.tmpl, embedded into the binary at build time (Go embed.FS) — not overridable by mounting. Files:

root.tmpl  user.tmpl  player.tmpl  registration.tmpl
complete-registration.tmpl  challenge.tmpl  admin.tmpl
layout.tmpl  header.tmpl  footer.tmpl  error.tmpl

To change them you must fork + rebuild:

Fork unmojang/drasl.
Edit view/*.tmpl (reword, restructure, add help text/links).
Build a custom image, push to your registry (or build locally).
Point image: in compose at your fork.

Maintenance cost: you now track upstream and rebase on releases. Only worth it if tier 2 + landing-page guide aren't enough.

Alternative to forking: build a thin custom frontend that talks to Drasl's HTTP API (see api.go) for the one flow guests care about (login + skin upload), hosted at e.g. ${BASE_DOMAIN}/skins. More code, but total UI control and no upstream coupling. Overkill for 4–10 friends.

Recommended path for Ulicraft

Tier 1: InstanceName = "Ulicraft Accounts", decide on bg/footer.
Tier 2: reskin style.css to match the landing page, swap logo + favicon.
Landing-page guide: add a /skins (or /help) page on the apex landing site — numbered steps + screenshots: register at auth., log in, upload skin, done. This is what actually makes it noob-friendly; Drasl stays the plumbing.
Skip tier 3 unless a specific page is confusing enough to justify a fork.

Skin/cape config flags: see plan/03-drasl.md and CLAUDE.md gotchas.
AllowTextureFromURL = true lets guests paste a skin URL (e.g. from a skin site) instead of uploading a file — friendlier for non-technical users.
