Configuration

Configuration

Xtarterize doesn’t require a config file. It detects your project’s stack automatically and applies only what’s appropriate.

Detection

When you run init, Xtarterize scans your project to build a ProjectProfile:

• Framework — React, Vue, Svelte, Solid, React Native, or Node (from package.json deps)
• Bundler — Vite, Next.js, TanStack Start, Expo, Webpack, or none
• Router — TanStack Router, React Router, Vue Router, Expo Router, or none
• Styling — Tailwind, CSS Modules, Styled Components, Vanilla Extract, NativeWind, or Vanilla
• Package Manager — pnpm, npm, yarn, or bun (from lockfiles or packageManager field)
• Monorepo — Detected via pnpm-workspace.yaml, turbo.json, packages/ + apps/ dirs
• GitHub — .github/ directory presence
• Existing Configs — Checks for biome.json, tsconfig.json, renovate.json, etc.

Detection Sources

package.json

Framework, bundler, router, styling, and TypeScript are all detected from dependencies and devDependencies.

Lock files

Package manager is detected from lock file presence: pnpm-lock.yaml, yarn.lock, package-lock.json, or bun.lock.

File system

Monorepo status, GitHub, and existing configs are detected by checking for specific files and directories.

Ambiguity Resolution

Note

If both react and react-native are detected, Xtarterize prompts you to clarify which describes the project. In CI mode (--quiet), it defaults to react.

Task Gating

Tasks are gated on the detected profile:

• Vite plugin tasks only run when bundler === 'vite'
• Monorepo tasks only run when monorepo === true
• CI tasks only run when hasGitHub === true
• TypeScript tasks only run when typescript === true

Parameterized Templates

All templates adapt to the detected profile:

• GitHub workflows use the detected package manager for install commands
• Knip entry points are inferred from the bundler/framework
• Plop generators vary by framework (React gets component+hook, Vue gets component+composable, etc.)
• VS Code extensions include framework-specific recommendations
• AGENTS.md includes framework-specific instructions

Backup System

Before any file is modified, Xtarterize creates a backup in .xtarterize/backups/. An index file tracks all backups.

• Directory.xtarterize/

  • Directorybackups/

    • .index.json
    • tsconfig.json.2024-01-15T10-30-00-000Z
    • biome.json.2024-01-15T10-30-00-000Z

Restore with:

npx xtarterize restore tsconfig.json
