Introduction

xtarterize is an adaptive CLI tool that automates the setup, enforcement, and ongoing synchronization of developer conformance configurations across JavaScript/TypeScript projects.

Why xtarterize?

Section titled “Why xtarterize?”

Modern JS/TS projects require a large and growing set of tooling configuration: linters, formatters, bundler plugins, TypeScript settings, CI/CD workflows, release automation, dependency management, editor settings, and AI agent skills. Setting these up consistently across projects is:

  • Repetitive - the same configs are rewritten or copy-pasted project to project
  • Error-prone - manual patching of package.json, tsconfig.json, or vite.config.ts often misses edge cases
  • Inconsistent - configs diverge between projects over time as standards evolve
  • Context-blind - a React project needs different config than a React Native or Vue project

xtarterize solves this by being detection-first, context-aware, non-destructive, idempotent, and evolvable.

How It Works

Section titled “How It Works”
  1. Detect - Scans your project to build a full ProjectProfile (framework, bundler, styling, package manager, monorepo status, existing configs)
  2. Resolve - Maps the profile to applicable conformance tasks (e.g., Vite tasks only for Vite projects)
  3. Check - Determines each task’s status: new (file doesn’t exist), patch (needs merging), skip (already conformant), or conflict (incompatible)
  4. Plan - Displays a conformance plan table for review
  5. Apply - Backs up files, then applies changes using deep merge or AST manipulation

Getting Help

If you have questions or need help:

  • Check the CLI Reference for all commands and flags
  • Review the Tasks Guide to see what conformance tasks are available
  • Look at the Contributing section if you want to contribute to the project

Starting a New Project?

Section titled “Starting a New Project?”

If you’re bootstrapping a fresh project, consider using create-xtarter-app first. It scaffolds curated starter templates (Next.js/Vite + Chakra/Tailwind/Hero UI) in seconds, then you can run xtarterize init to layer on additional conformance configs.

Step 1: Scaffold a new project from a template

Section titled “Step 1: Scaffold a new project from a template”
Terminal window
npm create xtarter-app@latest -- my-app

Step 2: Apply additional production-grade configs

Section titled “Step 2: Apply additional production-grade configs”
Terminal window
cd my-app
Terminal window
npx xtarterize@latest init
