Odoo ERP ported to Go — complete backend + original OWL frontend
Full port of Odoo's ERP system from Python to Go, with the original Odoo JavaScript frontend (OWL framework) running against the Go server. Backend (10,691 LoC Go): - Custom ORM: CRUD, domains→SQL with JOINs, computed fields, sequences - 93 models across 14 modules (base, account, sale, stock, purchase, hr, project, crm, fleet, product, l10n_de, google_address/translate/calendar) - Auth with bcrypt + session cookies - Setup wizard (company, SKR03 chart, admin, demo data) - Double-entry bookkeeping constraint - Sale→Invoice workflow (confirm SO → generate invoice → post) - SKR03 chart of accounts (110 accounts) + German taxes (USt/VSt) - Record rules (multi-company filter) - Google integrations as opt-in modules (Maps, Translate, Calendar) Frontend: - Odoo's original OWL webclient (503 JS modules, 378 XML templates) - JS transpiled via Odoo's js_transpiler (ES modules → odoo.define) - SCSS compiled to CSS (675KB) via dart-sass - XML templates compiled to registerTemplate() JS calls - Static file serving from Odoo source addons - Login page, session management, menu navigation - Contacts list view renders with real data from PostgreSQL Infrastructure: - 14MB single binary (CGO_ENABLED=0) - Docker Compose (Go server + PostgreSQL 16) - Zero phone-home (no outbound calls to odoo.com) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
