dotfig

One config to rule them all — generate ESLint, Prettier, TypeScript, EditorConfig from a single dotfig.yml

한국어 | 中文 | 日本語

Why?

Every new project needs 5–10 config files: eslint.config.js, .prettierrc, tsconfig.json, .editorconfig, .gitignore... They all share overlapping settings (indent size, quotes, semicolons) but each uses a different format.

dotfig lets you define your preferences once in dotfig.yml and generates all config files automatically.

dotfig.yml  →  eslint.config.js
             →  .prettierrc
             →  tsconfig.json
             →  .editorconfig
             →  .gitignore

Install

npm install -g dotfig

Quick Start

# Interactive setup — creates dotfig.yml
dotfig init

# Generate all config files
dotfig sync

dotfig.yml

version: 1
preset: typescript          # typescript | react | node

rules:                      # Shared across all tools
  indent: 2                 # → prettier, editorconfig, eslint
  semicolons: false         # → prettier, eslint
  quotes: single            # → prettier, eslint
  line-width: 100           # → prettier, editorconfig, eslint

typescript:                 # tsconfig.json options
  strict: true
  target: ES2024
  jsx: react-jsx            # Auto-set by react preset
  paths:
    "@/*": ["./src/*"]

lint:                       # Extra ESLint rules
  no-unused-vars: error
  no-console: warn

format:                     # Extra Prettier options
  trailing-comma: all
  bracket-spacing: true

gitignore:                  # Extra .gitignore patterns
  extra:
    - "*.local"
    - ".env"

How It Works

The rules section is the key idea. Define once, apply everywhere:

dotfig.yml	Prettier	ESLint	EditorConfig
indent: 2	tabWidth: 2	indent rule	indent_size = 2
semicolons: false	semi: false	semi rule	—
quotes: single	singleQuote: true	quotes rule	—
line-width: 100	printWidth: 100	max-len rule	max_line_length = 100

Generated Files

Source	Output
rules + format	.prettierrc
rules + lint	eslint.config.js (flat config)
rules + typescript	tsconfig.json
rules	.editorconfig
preset + gitignore	.gitignore

Presets

Presets provide sensible defaults. Your explicit dotfig.yml values always take precedence.

Preset	Description
typescript	Strict TypeScript + ESM + Prettier defaults
react	TypeScript + JSX + React ESLint plugins
node	TypeScript + Node.js target

Commands

dotfig init

Interactive wizard that creates dotfig.yml by asking your preferences:

• Preset selection (typescript / react / node)
• Indent size, semicolons, quote style, line width

dotfig sync

Reads dotfig.yml and generates all config files in the current directory.

$ dotfig sync
✓ 생성 .editorconfig
✓ 생성 .gitignore
✓ 생성 .prettierrc
✓ 생성 tsconfig.json
✓ 생성 eslint.config.js

✓ 5개 설정 파일이 생성되었습니다.
