Dasko 9aaafa2358 refactor(izvestaji): direktan SQL dashboard/izveštaja u IzvestajRepository
dashboard.go i izvestaji.go više ne sadrže direktan SQL — svih 12 upita
prebačeno u novi IzvestajRepository (internal/db/sqlite/izvestaj.go). Repo vraća
sirove redove (model.*Red tipovi), a handleri zadržavaju prezentaciju
(formatiranje datuma, boje tačaka, rang, sklapanje niza 12 meseci). Žičenje kroz
Handler.IzvestajRepo (+ reinicijalizuj).

Dobici: testabilnost (dodati integracioni testovi izvestaj_test.go) i put ka
Postgres-u bez prepravke handlera. dashboard.prihod provera ostaje u handleru.

Van obima: middleware/flash.go i backup VACUUM INTO (ne pripadaju repo sloju).

NTech

🇷🇸 Srpska verzija

Go Version License

image

A business application for computer repair shop management, parts inventory tracking, and sales. Built with Go, it runs in the browser and requires no internet connection or external services.

⚠️ The project is under active development. It is not ready for production use.


About the Project

NTech is an internal application built for a specific user — a computer repair shop that, in addition to repairs, manages a parts inventory, sales of components and pre-built configurations, as well as client and supplier records.

The goal is simple: everything the repair shop needs to track is located in one place, without relying on Excel spreadsheets or paper records.


Features

Implemented

  • Initial setup on first run (setup wizard)
  • Database migration system
  • User interface — sidebar navigation, theme system (dark/light), dashboard with statistics
  • User login — server-side sessions, account locking
  • Two-factor authentication (TOTP) — activation with a QR code, backup codes
  • Brute-force protection — IP locking after 5 failed attempts within 15 minutes
  • CSRF protection — double-submit cookie pattern, automatic token injection into all forms
  • Security HTTP headers (CSP, X-Frame-Options, Referrer-Policy, nosniff...)
  • Login attempt logging — history by user, IP, reason, date
  • Users and roles — admin panel, user management
  • Inventory — items, categories, filtering, critical stock levels
  • Service orders — intake, status bar, costs, receipt
  • Sales orders — items, calculation, receipt with company and client details
  • Procurement — records of purchases from suppliers
  • Clients and suppliers — contact database
  • Reminders — records with deadlines
  • Reports — revenue overview, inventory status
  • Settings — company name, address, Tax ID (PIB), logo; theme toggle
  • Background images — login page and app, with blur, transparency and glass effect
  • Personal theme and background — each user can set their own theme and background image
  • Permission matrix (RBAC) — admin panel for setting permissions by role
  • Flash messages — one-time feedback after an action
  • Automatic SQLite backup — with configurable number of retained copies
  • Charts — monthly revenue on reports (Chart.js)

Planned

  • Fiscalization and VAT calculation (specification in Project.md)
  • PostgreSQL support (for multi-user environments)
  • WebAuthn / Passkey login (database schema is already prepared)
  • Notifications (email / WhatsApp) — deferred to a later phase
  • Barcode scanning via camera — deferred to a later phase

Technologies

Technology Role
Go backend language
chi HTTP router
