- Native <dialog> modal infra (CSS + ~30 LOC JS, no framework) used for create forms and delete confirmations. - Index pages become listing-only: + Create button opens a modal; the broken blueprint Actions column and inline overlay edit cells are gone. - Server detail gains a blueprint reassignment form; existing Delete button now opens a confirmation modal before tearing down the runtime. - Blueprint detail gains a Delete button + confirmation modal (was unreachable from the UI before). - New overlay detail page at /overlays/<id> with edit form, "Used by" blueprints list, and delete (admin only). - Server create: port field is now optional; backend auto-assigns the next free port from LEFT4ME_PORT_RANGE_START/_END (default 27015-27115). 409 on range exhaustion. - New routes: POST /blueprints/<id>/delete (form sentinel matching overlays pattern), POST /servers/<id> (form-friendly blueprint reassign), GET /overlays/<id>. - Server delete operation now redirects to /servers; overlay update redirects to /overlays/<id>. Server rename remains unsupported pending an id-vs-name design pass for l4d2host (the runtime directory is name-keyed; renaming would orphan files).

l4d2-web-app
Flask web app for managing L4D2 servers through user-private blueprints.
Key v1 behaviors
- Local username/password login; no public signup
- Admin-managed overlay catalog
- Private blueprints per user
- Server creation from blueprints (live-linked; no per-server blueprint overrides)
- Async job model with persisted command logs in
job_logs - Desired vs actual state model
- Live logs for jobs and servers via SSE endpoints
- Host operations go through
l4d2ctlvia a local host command runner, not directl4d2hostimports
Frontend constraints
- Server-rendered templates (Jinja)
- Vendored HTMX (
static/vendor/htmx.min.js) - Custom CSS only
- Tokenized, consistent link and accent colors
Development
python3 -m venv .venv
.venv/bin/pip install -e .
.venv/bin/pytest tests -q
Configuration
The web app reads these settings from the environment:
DATABASE_URL: SQLAlchemy database URL, for examplesqlite:////var/lib/left4me/left4me.db.SECRET_KEY: Flask secret key used for sessions and CSRF-sensitive state.JOB_WORKER_THREADS: number of background job worker threads.
In the systemd deployment, environment is loaded from /etc/left4me/host.env and /etc/left4me/web.env.
Admin Bootstrap
Create the first admin account with the Flask CLI. Provide the password through LEFT4ME_ADMIN_PASSWORD:
LEFT4ME_ADMIN_PASSWORD='change-me' flask create-user <username> --admin
