Blarn

A Yarn wrapper with extra functionality

Features

• Automatically add and remove TypeScript @types packages when adding or removing packages in a TypeScript project
• List linked and linkable packages, unlink all packages and automatically rerun Yarn after unlinking packages.

Usage

Requirements

• You must have Yarn 1 installed and available on your path

Installation

// npm
npm install -g blarn

// yarn
yarn global add blarn

Upgrading

// npm
npm install -g blarn

// yarn
yarn global upgrade blarn --latest

Running Yarn commands

Blarn will pass all commands and arguments through to Yarn. When adding packages in a TypeScript project it will execute a second yarn add command to add any available @types packages as dev dependencies. When removing packages any corresponding @types packages will be added to the list of packages to remove.

Examples

Adding packages

blarn add yargs

If you run this command in a TypeScript project yargs will be installed as a dependency and @types/yargs will be installed as a dev dependency. If you run this command in a JavaScript project only yargs will be installed as a dependency.

Removing packages

blarn remove yargs

If you run this command in a TypeScript project and @types/yargs exists in package.json both yargs and @types/yargs will be removed. If you run this command in a JavaScript project only yargs will be removed.
