feat(l4d2-web): workshop overlay UI (routes + templates)
Adds workshop_routes blueprint with add-items / remove-item / manual-
build endpoints plus admin /admin/workshop/refresh. Add-items handles
single ID, single URL, multi-line batch, or a collection ID; auto-
enqueues a coalesced build_overlay job per call. Reject non-L4D2 items
with 400, duplicate associations with friendly toast, intruders with
403.

Generalizes overlay_routes: type+name only on create (no path field);
external is admin-only and system-wide, workshop is per-user and
auto-pathed. Update is name-only. Delete recursively removes the
on-disk dir only for managed paths (path == str(id)); legacy externals
are left in place. The pre-existing in-use guard is preserved.

Page routes filter the overlay listing by user permissions and load
workshop items + the latest related job for the detail view.

Templates: unified Create modal with type radio (no path field).
Type-aware overlay detail: workshop overlays show a multi-line input
+ items/collection radio + item table partial with thumbnails, manual
Rebuild button, and a small status indicator pulled from the latest
related job. Admin page gets a "Refresh all workshop items" button.

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 l4d2ctl via a local host command runner, not direct l4d2host imports

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 example sqlite:////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
