Yarn to npm

A CLI tool that simplifies the migration of projects from Yarn to npm. This tool converts the yarn.lock file to package-lock.json and updates package.json scripts to use npm commands.

Features

• Converts yarn.lock to package-lock.json using synp.
• Updates package.json scripts to replace Yarn commands with npm equivalents.
• Handles common Yarn commands like yarn add, yarn remove, yarn global, and shorthand script commands.
• Supports commands that should be run directly, such as jest, eslint, prettier, tsc, and serverless.

Installation

You can install the CLI globally via npm:

npm install -g yarn-to-npm-cli

Usage

To migrate your project from Yarn to npm, navigate to the root of your project directory and run:

yarn-to-npm migrate

This command will:

1. Convert your yarn.lock file to a package-lock.json file.
2. Update all yarn commands in your package.json scripts to their npm equivalents.

Example

Before migration:

"scripts": {
"start": "yarn start && yarn build",
"build": "yarn run build && yarn add lodash",
"test": "yarn test && yarn install",
"lint": "yarn eslint .",
"dev": "yarn run dev"
}

After migration:

"scripts": {
"start": "npm run start && npm run build",
"build": "npm run build && npm install lodash",
"test": "npm run test && npm install",
"lint": "eslint .",
"dev": "npm run dev"
}

• migrate: Converts the yarn.lock file to package-lock.json and updates package.json scripts to use npm commands.
