Mrm

Command line tool to help you keep configuration (package.json, .gitignore, .eslintrc, etc.) of your open source projects in sync.

Features

• Doesn’t overwrite your data unless you want to
• Minimal changes: keeps the original file formatting or read the style from EditorConfig
• Minimal configuration: tries to infer configuration from the project itself or from the environment
• Customizable tasks for popular tools like ESLint, Prettier, lint-staged, etc. included
• Custom tasks and tools to work with JSON, YAML, INI, Markdown and new line separated text files
• Sharing tasks via npm and grouping them into presets

Motivation

Most of the available tools are template based. Template approach works moderately well for new project generation but doesn’t work well for updating. Mrm’s approach is closer to codemods than templates.
