Introduction to Devark

Devark is a backend scaffolding CLI tool that brings the modular, “add what you need” philosophy of shadcn/ui to backend development. Instead of starting from scratch or committing to a heavy framework, Devark lets you add production-ready features to your existing Node.js projects with a single command.

​
What is Devark?

Devark is a CLI tool that scaffolds modern backend features instantly with modular, production-ready templates. It supports both JavaScript and TypeScript, automatically detects your package manager, and integrates seamlessly into existing projects.

That’s it. Google OAuth authentication is now integrated into your project with routes, middleware, configuration, and environment variables all set up.

​
Why Devark?

Building backend features from scratch is time-consuming and error-prone. Whether it’s OAuth flows, email verification, or database setup, you end up writing the same boilerplate code for every new project. Devark solves this by:
  • Modular approach - Add only the features you need, when you need them
  • Production-ready code - Battle-tested templates that follow best practices
  • Framework agnostic - Works with your existing Express.js projects
  • Language flexible - Full support for both JavaScript and TypeScript
  • Smart detection - Automatically detects your package manager (npm, pnpm, yarn)
  • Zero configuration - Sensible defaults with options to customize

​

​
How It Works

Devark follows a simple, predictable workflow:
1

Validate your project

Ensures you have package.json and detects your package manager
2

Install dependencies

Automatically installs required npm packages for the feature
3

Generate code

Creates routes, controllers, and configuration files from templates
4

Update configuration

Modifies your entry file (app.js) and updates .env with required variables
All code is generated locally in your project, giving you full control to customize and extend as needed.

​
Example: Adding Google OAuth

Here’s what happens when you run devark add google-oauth: 
devark add google-oauth
Devark will:
  1. Prompt you to choose JavaScript or TypeScript
  2. Ask for your Google OAuth credentials (or use placeholders)
  3. Install dependencies: passport, passport-google-oauth20, express-session
  4. Generate authentication routes and Passport configuration
  5. Update your app.js with OAuth middleware
  6. Add environment variables to .env
All generated code is placed in standard directories (routes/, config/, controllers/) making it easy to find and modify.

​
Philosophy

Devark is designed to be:
  • Transparent - All code is generated in your project, no black boxes
  • Flexible - Templates are starting points, customize freely
  • Minimal - Only adds what you explicitly request
  • Standard - Follows Node.js best practices and common patterns
