Initial implementation of inventree
A small IT asset inventory system built around a nested folder tree, matching the project brief: Go + html/template + Bootstrap 5 + vanilla JS, SQLite storage (WAL, FKs, migrations), embedded templates/static assets, single compiled binary. - AJAX-driven inventory tree: lazy-loaded folder expansion with per-user persisted expand state, drag-and-drop move for folders/assets, safe delete-with-relocate-or-cascade confirmation, search with breadcrumbs. - Assets: CRUD, duplicate, move, auto-generated IT-000001-style IDs, CSV import (with optional folder auto-create) and export. - Admin-defined item types with custom fields (text/long_text/number/date/ boolean/dropdown/url/ip_address). - Configurable statuses, session-based auth (bcrypt, secure cookies), admin/user roles, user management. - CLI: serve, version, database migrate, database backup; /healthz; graceful shutdown; Dockerfile/docker-compose/systemd unit; Go test suite.
