LFify

A lightweight Node.js program to convert CRLF to LF line endings.
It is useful when your development environment is Windows.

Getting started

Using CLI options (no config file needed)

npx lfify --include "**/*.js" --exclude "node_modules/**"

Using config file

Create .lfifyrc.json:

{
  "entry": "./",
  "include": [
    "**/*.{js,ts,jsx,tsx}",
    "**/*.{json,md}",
    "**/*.{css,scss}",
    "**/*.{html,vue}"
  ],
  "exclude": [
    "node_modules/**",
    ".git/**",
    "dist/**",
    "build/**",
    "coverage/**"
  ],
  "logLevel": "error"
}

Then run:

npx lfify

Options

| Option | Description | | --------------------- | ----------------------------------------------------------------------------- | | --config <path> | Specify a custom path for the configuration file. Default is .lfifyrc.json. | | --entry <path> | Specify the entry directory to process. Default is ./. | | --include <pattern> | Glob pattern(s) to include. Can be used multiple times. | | --exclude <pattern> | Glob pattern(s) to exclude. Can be used multiple times. | | --log-level <level> | Set log level: error, warn, or info. Default is error. |

Examples

# Process all JavaScript files, exclude node_modules
npx lfify --include "**/*.js" --exclude "node_modules/**"

# Process multiple file types
npx lfify --include "**/*.js" --include "**/*.ts" --exclude "node_modules/**" --exclude ".git/**"

# Process files in a specific directory
npx lfify --entry ./src --include "**/*.js"

# Use a custom config file
npx lfify --config ./custom-config.json

# Show detailed progress logs
npx lfify --log-level > warn

Default behavior

When no config file is found and no CLI options are provided, lfify uses sensible defaults:

• include: **/* (all files)
• exclude: node_modules/**, .git/**, dist/**, build/**, coverage/**
• logLevel: error

Priority

CLI options take precedence over config file values:

1. CLI arguments (highest)
2. Config file
3. Default values (lowest)
