SaaSKit Starter

SaaSKit Starter — a saas project built with Node.js, Express, MongoDB. Production posture, clean architecture, and a focused feature set.

Overview

SaaSKit Starter is a production-oriented saas project built to demonstrate serious full-stack engineering: clean architecture, secure defaults, and an interface that respects the user's time.

The core idea is simple — automate a repetitive workflow — and the execution focuses on doing that one thing exceptionally well.

Key features

- Structured data layer with MongoDB, indexed for the queries that actually run. - Server-rendered pages where they make sense, with the stack: Node.js, Express, MongoDB, React, Vercel. - Role-based admin workflow for managing content, projects, or orders. - Security defaults: sessions, CSRF protection, rate limiting, and sanitized inputs. - SEO-ready output: meta tags, structured data, sitemaps, and clean canonical URLs.

Architecture

The application follows a layered MVC pattern. Routes handle HTTP concerns, services carry business rules, and repositories isolate every database interaction. This separation keeps the codebase easy to test and easy to navigate, even as features accumulate.


// Example: a thin controller delegating to the service layer

router.get("/", asyncHandler(async (req, res) => {

  const data = await getIndexData({ page: req.query.page });

  res.render("index", data);

}));

Lessons from shipping

The most important decisions were not technical — they were about scope. Cutting features that did not serve the core use case kept the project shippable and the codebase honest. When in doubt, ship the version that solves the real problem first.
